Systematic paleontology of Sulaimanitherium dhanotri is as follows:
Mammalia Linnaeus ;
Cetacea Brisson ;
Sulaimanitherium dhanotri ;
Sulaimanitherium dhanotri holotypic vertebral column and a few small pieces of limb elements found in the Middle Eocene (about 40 Million years ago) Drazinda shale of Kahan Group from Zamri type locality, Drug Tehsil, Musakhel district of Balochistan. The Drazinda Formation consists of marine green to grey shale in the lower and middle portion (host of Sulaimanitherium), however the upper part is chocolate to maroon. The fossils are hosted by the museum of Geological Survey of Pakistan in Quetta. Genus name Sulaimanitherium is honoring the host Sulaiman Range. Species name S. dhanotri honoring the tribe name of the M. Shahid Ishaq Dhanotr who collected these fossil bones.
2.1. Diagnosis of Sulaimanitherium dhanotri Basilosauridae
Sulaimanitherium dhanotri shares with the Basilosauridae as the long lumbar vertebrae because the other older cetaceans pakicetids, ambulocetids, remingtonocetids, protocetids and dorudontids bear short posterior thoracic, lumbar and anterior caudal vertebrae. Sulaimanitherium dhanotri characterized by the following features. Sulaimanitherium dhanotri have relatively more deep, stocky and less elongated lumbar centra while Basilosaurus cetoides have shallow, slender and more elongated lumbar centra. Sulaimanitherium dhanotri lumber centra are less elongated than Basilosaurus drazindai and Basilosaurus isis. Sulaimanitherium dhanotri lumber centra are more elongated than Basiloterus hussaini. Sulaimanitherium dhanotri lumber centra are transversely more thicker than Basilosaurus drazindai and Basiloterus hussaini. Sulaimanitherium dhanotri have two recessed vascular fenestrae divided by one thin bony septa or partition located in a deep central concavity on the ventral and also dorsal surfaces of lumbar centra while Basiloterus hussaini  from Pakistan have three recessed vascular fenestrae divided by thin bony partitions in the ventral concavity. Sulaimanitherium dhanotri have relatively less longer, less deeper and more thicker lumbar centra than Basilosaurus drazindai lumbar centra of about same position. Sulaimanitherium dhanotri have possibly three fenestrae forming triangle in the core of radial rugosities on anterior view of lumbar centrum, while Basilosaurus drazindai and Basiloterus hussaini lack these three fenestra. Roots of the transverse processes oriented on the mid of lateroventral margin in Sulaimanitherium dhanotri while transverse process arise in the anterolateral margin of the vertebral body of Basilosaurus drazindai . Transverse process of Sulaimanitherium dhanotri is relatively considerably anteroposteriorly less long at the base than the transverse process of Basilosaurus drazindai. As usual in archaeocetes, the pedicles arise closer to the anterior end of the centrum than to the posterior end of Basilosaurus drazindai  while in Sulaimanitherium dhanotri the pedicles are found in the mid centre (centrally oriented or feebly close to anterior termination of centrum. Neural canal of Sulaimanitherium dhanotri is transversely less broad than Basilosaurus drazindai while the lumbar centra are thicker in Sulaimanitherium dhanotri than Basilosaurus drazindai. Cervical centra have strongly ventrally reduced surface. Ventrally reduced surface of cervical centrum is laterally bounded by two ventral keel (one on each side). The cervical centra forms hexagonal wedge shape, two faces on left lateral and two faces on right lateral and one ventral reduced face and one dorsal surface which is base of neural canal.
2.2. Description of Sulaimanitherium dhanotri Basilosauridae
100 holotypic specimens belonging to more than forty vertebrae including cervical, thoracic, lumbar and caudal vertebrae and more than fifty cross sections of ribs, appendicular bones, transverse processes, neural spines, etc. (Figure 1) (Figure 2). These fossils are found as about 10 - 12 m long belt on marine green shale showing associated nature and further there is no duplication and size are same, showing the one individual holotypic animal. The recognizable specimens include 5 cervical vertebrae, 3 or more thoracic, 5 or more lumbar and 3 or more caudal vertebrae which provide facility for description and show a number of important diagnostic landmarks that are best studied in comparison with other basilosaurids. These vertebrae are distinctive in the size, centrum proportions and morphology. The cervical vertebrae include almost complete series (Figure 1). The middle and lower part of the atlas (first cervical vertebra) is preserved and has a very thin vertebral circular body forms and consists of lower and middle parts forming ring shape around the foramen magnum. Atlas centrum is shallow and broadest for adjustment of occipital condyles. The atlas vertebra (centrum with pedicle and neural arch) is subcircular shaped vertebra. The neural canal is generally round, and may be the same size as the foramen magnum. The ventral face is very broad than all other cervicals. Neural canal in atlas seems to be relatively broader than the following cervicals. The dens or odontoid process is destroyed in the axis body.
The cervical vertebral body (centrum) is broad with low height and dorsoventrally compressed. The cervicals (except atlas) and probably anterior thoracic have wedge-shaped. The cervical centra have strongly ventrally reduced surface. The ventrally reduced surface is laterally bounded by two ventral keel (one on

each side). The cervical centra forms hexagonal wedge shape, two faces on left lateral and two faces on right lateral and one ventral reduced face and one dorsal surface which is the base of neural canal. The vertebral body and pedicle and along with neural arch forms the dorsoventrally oval shape. The ventral face is reduced and laterally bounded by keel on each side (on left lateral and on right lateral sides). Then the lower lateral face is started as inclined laterodorsally and then it forms a lateral keel ridge and then dorsal lateral surface is converged (on both sides) toward the neural canal and last face is represented by horizontally straight face and it forms the base of neural canal. The vertebral body or centrum maximum width is 5 cm, height is about 3 cm (up to ventralmost part of neural canal) and length without epiphyses is 5 cm. The epiphyses are well preserved in two vertebrae. Ventrally the cervical centra have reduced plane surface. This ventral plane surface is anteroposteriorly elongated. This surface is laterally bound by lateral inclined surface. There is a pair of ventral keel, each is located on the contact of reduced ventral and inclined lateral surface. Dorsally the cervical centra are horizontal for the inset of neural canal. The lateral surface is inclined plane which dorsally joined the pedicle. The anterior and posterior articular surfaces are set obliquely. It has multi-angled curved form of centra alongwith anterior and posterior surfaces. The measurement of faces in one centrum are as follows; the ventral horizontal plane is narrow (2 cm transversely wide) and long (5 cm anteroposteriorly long), then inclined lateral surface started in dorsolaterally direction and its height or depth is 5 cm from base (laterally equal to horizontal plane) to the upper point (central axis of neural canal) and 5 cm anteroposteriorly long. The central part of ventral surface is flat longitudinally. The pedicle of cervical centra is thick up to 2 cm and cover anteroposteriorly all dorsal surface of centrum. The neural arch has robust postzygapophysis which seems to be not extended beyond centrum. The neural canal of cervical centrum is deep, generally forming subcircular to dorsoventrally suboval shape. In one vertebra the diameter of neural canal is about 3.5 cm transversely and 4 cm dorsoventrally. The transverse processes including diapophysis are laterally oriented in the cervical found on the anterior epiphysis of cervical centra. The transverse processes are preserved on the anterior epiphysis of cervical vertebrae. As a whole cervical vertebrae are tall. The centra are broad. The neural canals are deep. Further neural canal is tall or deep in all cervical except anteriormost one or two cervicals. In this regards the cervical vertebrae of Sulaimanitherium dhanotri matches closely with cervicals of Zygorhiza kochii .
The thoracic centra are relatively shorter than lumbar and longer than cervicals. Thoracic centra are tall than cervical centrum but almost equal to lumbars. Thoracic centra are more wide than cervical centrum but almost equal to lumbars. The transverse processes are situated more dorsally on the vertebra body than lumbars. The transverse processes are lateroventrally (started from mid height of centra) oriented in the a few last thoracics. The centra are slightly broad. Its width is slightly more than height. The height and width almost remain constant in lumbars while length is higly increased. The cranial epiphysis is suboval. The transverse process is triangular to subcircular and thicker dorsoventrally and oriented on the lateral sides of thoracic centra. The epiphysis are massive (not spongy) and porcellaneous type. The epiphysis show ring structure development. These are recognized by the triangular to subrounded shaped transverse process located on the lateral sides of the vertebral bodies. The vertebral bodies have width, depth and length more than cenvical and less than lumbars.
The lumbar centra are anteroposteriorly elongated and transversely oval to suboval shaped. The height and width are almost same as in thoracic, but slightly more than anterior caudals. The ventral position and downward trend of transverse process of this vertebra shows its assignment to lumbar because in dorsal position is more dorsally oriented . One longest preserved centrum of Sulaimanitherium dhanotri is 27 centmeter (cm) long and 17 cm wide and 13 cm high while the Basilosaurus drazindai have different proportion like 30 cm long, 17 cm wide and 14.5 cm high and Basiloterus hussaini have also different proportion like 20 cm long, 15 cm wide and 13.3 cm high. Sulaimanitherium dhanotri have relatively less long, less deep and more thicker lumbar centra than Basilosaurus drazindai lumbar centra of same position. The lumbar centra of Sulaimanitherium dhanotri is relatively less elongated than Basilosaurus drazindai and Basilosaurus isis. The lumbar centra of Sulaimanitherium dhanotri is relatively more longer than Basiloterus hussaini. The lumbar centra are broad as the thoracic and cervical vertebrae. The posterior and anterior parts of centra are plain and show radial texture rugosities suturing with epiphyses. The centra are covered with radiating bony rugosities that interdigitated with the missing epiphyses. The lumbar vertebrae are feebly waisted due to incursion of two ventral fenestrae. Further the lumbar centra are slightly dorsoventrally narrow in the middle of the centrum while anterior and posterior portion of centra is relatively high. The central or sagital ventral keel is not found in any thoracic and lumbar vertebrae but two ventral keels are found in cervicals. Anterior epiphysis or end plate is present in a few vertebrae. Ring structure found on anterior/posterior face of centrum epiphysis. The dorsal and ventral surfaces of centra are not flat but have mid concavities in the ventral and dorsal surfaces. The dorsal surface of centra mostly resemble with the ventral surface, only difference is the ventrally two long and thick vascular fenestrae/foramina/vascular canal and dorsally two relatively shorter, circular and thin fenestrae. These fenestrae typically perforates basilosaurid vertebrae. The mid-dorsal and ventral surfaces show moieties/equal parts/mirror images. There are two rounded vascular fenestrae (left and right vascular fenestrae which are separated by a central thin bony lamina) between the pedicles in Sulaimanitherum dhanotri while only one rounded vascular fenestra is reported in Basilosaurus isis from Jordan . Between left and right transverse process there is a pair of conspicuous, anteroposteriorly elongated oval-shaped, transversely narrow opening fenestrae for the dorsoventral vascular canal. There are two vascular fenestrae (left and right vascular fenestrae which are separated by one central thin bony lamina) in Sulaimanitherum dhanotri which are anteroposteriorly elongated on ventral surface, and rounded on dorsal surface, while three vascular fenestrae separated by bony partitions (2 central thin bony laminae) are reported in Basiloterus hussaini  from Pakistan. The vertebra has a broad, shallow, smooth groove on each side and these broad grooves continue dorsally in the centrum. The sediments filled the dorsoventral vascular canals.
As usual in archaeocetes, the pedicles arise closer to the anterior end of the centrum than to the posterior end of Basilosaurus drazindai  while in Sulaimanitherium dhanotri the pedicles are found almost in the mid centre (centrally oriented or feebly close to anterior termination of centrum) of centrum. The pedicles measure upto 11 cm in length anteroposteriorly and 4.5 cm in width mediolaterally at the base, and it is located in the middle of centrum. Sulaimanitherium dhanotri has centrally oriented thick pedicles upto 4.5 cm while Basilosaurus drazindai have relatively thin pedicles upto 3 cm thick transversely while their anteroposterior lengths are almost same. The pedicle and neural arch cover all along the dorsal length of cervical centra. The neural arch is dorsally broken but its broken surface show that the neural spine is anteroposteriorly long and located in the central longitudinal axis (sagital axis) and posteriorly it becomes thick and approached close to the postzygapophyses (or its remnant). The pre-zygapophysis seems to be relatively low but completely not preserved. The left or right postzygapophyses of Sulaimanitherium dhanotri are thicker elements than Basilosaurus drazindai. The postzygapophyses are preserved posteriorly at the level of preserved neural canal.
The transverse width of neural canal anteriorly about 9 cm and posteriorly about 9.5 cm of Sulaimanitherium dhanotri while it is anteriorly 11 cm and posteriorly 11.5 cm of Basilosaurus drazindai. The neural canal of Sulaimanitherium dhanotri is transversely less broad than Basilosaurus drazindai while the lumbar centra are thicker in Sulaimanitherium dhanotri than Basilosaurus drazindai. The neural canal/cerebral canal of a few vertebrae are preserved perfectly as filled mudstone (Figure 2). The neural canal is a thick, broad and wide canal which is ventrally bifurcated centrally by embedded mid dorsal keel in centra. The bifurcated neural canal is partially subdivided into left and right neural subcanal. At fenestra level the neural canal is relatively more deep and convexing showing connection with the vascular anal. The lateral surface of neural canal is rounded. The dorsal part of neural canal represents sagital anteroposteriorly elongated keel formed by fellow neural arches. The posteriormost part of neural canal is formed by three dorsal keels or crests, one major crest at sagital while other smaller one crest on both left and right limb/flanks. Anteriormost part of neural canal show only one dorsal crest or keel on sagital line.
The transverse process of Sulaimanitherium dhanotri and Basilosaurus drazindai have considerably different proportions and also different positions. The roots of the transverse processes oriented on the mid of lateroventral margin in Sulaimanitherium dhanotri while transverse process arise in the anterolateral margin of the vertebral body of Basilosaurus drazindai . The transverse process of Sulaimanitherium dhanotri at base have anteroposterior length 12 cm and width 4 cm, while Basilosaurus drazindai at base have anteroposterior

length 15.5 cm and 4 cm in width. In this way the transverse process of Sulaimanitherium dhanotri is relatively considerably less long than the transverse process of Basilosaurus drazindai.
No any sacral (fused and coosified vertebrae between the caudal and lumbar vertebrae) are not found. The supposed caudal vertebrae are considerably relatively less long than lumbar. No large limb bones are found only small cross section are found. Sulaimanitherium dhanotri has subtriangular transverse process on moderately long distal thoracic while Chrysocetus fouadassii  from Morocco have anteroposteriorly elongated oval or elliptical shape on short distal thoracics. The Sulaimanitherium dhanotri has relatively large and long lumbar vertebrae while Platyosphys aithai have relatively short lumbars. Further the transverse process of lumbar vertebrae of Sulaimanitherium dhanotri are relatively anteroposteriorly short (less elongated) while Platyosphys aithai have relatively anteroposteriorly long transverse process of lumbar vertebrae. The Sulaimanitherium dhanotri have centrally oriented transverse process (anteroposteriorly located in the centre ventral margin of lateral sides while the Eocetus schweinfurthi of southwestern Morocco and Eocetus drazindai (Basilosaurus drazindai) of Pakistan have anteriorly oriented transverse process. Further the length of lumbar centrum of Sulaimanitherium dhanotri is relatively less than the Eocetus drazindai of Pakistan. B. cetoides lumbar and distal thoracic centra are slender and elongated (height is less and length is high) while Sulaimanitherium dhanotri have relatively less elongated and more deep (high) centra. Basilosaurus is the first Archaeoceti named by . Sulaimanitherium dhanotri is among the largest Basilosauridae.
3. New Baluchithere Rhinoceros from Balochistan Basin
Systematic paleontology of Pakitherium shagalai is as follows:
Pakitherium shagalai ;
Pakitherium shagalai new genus and new species based on cranial and postcranial skeleton found from the Early Eocene Shagala formation (terrestrial red mud and sandstone bone bearing; 50 - 45 Ma) of Shagala Group of Shagala type locality (which is 12 km northwest of Shagala town), Kamardin Kareez, Zhob district, Balochistan. These bones are hosted in museum of Geological Survey of Pakistan in Quetta. Genus name Pakitherium honoring the host country Pakistan and therium for beast. Species name P. shagalai honors the host Shagala formation, area and town. Pakitherium shagalai shared with baluchithere giant rhinoceros Rhinocerotoidea on the basis of enormous thick and relatively less long lower canine (tusk like), the huge and gigantic size and shape of limb bones and ribs. Pakitherium shagalai characterized by enormous thick root with relatively less long tapering canine like incisor (tusk like) with lateral keel and subcircular cross section and thick and huge postcranial skeleton. Further this incisor is relatively less thick and less long (tapering) which is different from more long and more thick incisor of Buzdartherium gulkirao. The new genera Buzdartherium from Sulaiman basin (which is also host of Paraceratherium and Baluchitherium) and Pakitherium first time from Balochistan basin based on cranial and postcranial skeletons and can help for correlation with Paraceratherium cranium and Baluchitherium postcranial skeleton from Pakistan.
Twenty seven (MSID-201 to MSID-227) holotypic cranial (tusk/canine like thick and long tooth) and postcranial skeleton like centrum, a pair of proximal metapodial, a pair of distal ribs, cross section of leg bone and many cross section of alae processes, ribs, neural spines, etc belonging to one individual due to close finding and size matching and no duplication. The canine like 1st incisor root is much thick, stout and massive while tapering crown show black/dark grey enamel (Figure 3). Its cone is blunted/partially broken but its large diameter and massive root morphology show its position as 1st incisor of lower jaw. The broken end of crown show green/light green materials. This lower incisor is directed forward. The preserved length of crown is 6 cm. The lateral maximum diameter at the base of crown is 5 cm and anteroposterior diameter is 6 cm. This incisor show lateral keel. The root is much thicker and representing for its position as 1st incisor (or may be forward pointing lower tooth). This incisor presents high specialization. The partial centrum may belong to thoracic vertebra. One lateral side of the wedge shape centrum is preserved and remaining portion is broken. The preserved posterior/anterior articular surface is slightly inclined. The ventral surface is partially preserved. The central part of ventral surface is smooth horizontal. Lateral sides incline dorsolaterally and its length of ventrodorsal inclined height is 4.5 cm. This centrum resembles closely with the Baluchitherium thoracic centra. However the size and inclinations are also different suggesting different genus. The distal parts of a pair of ribs which show huge sizes and thickness. The width and depth of preserved rib are 6 cm and 4 cm, and preserved length is 15 cm (Figure 3). These distal ribs are not plain but show little concavo-convexo feature. One cross section of limb bone most probably radius or may be fibula diaphysis is also found. This cross section is tapering rapidly on one side than on other side (Figure 3). The collected bone is only diaphysis and proximal or distal epiphyses are damaged because in adult the proximal and distal epiphyses are fused with diaphysis. On the preserved proximal part its maximum dimensions/diameters are 9 cm and 6 cm which also show oval shape diaphysis. The distal part show dimensions of 7 cm and 5 cm and also oval shape. The surface is smooth. The cortical (outer) part of the diaphysis is less than 1 cm. The proximal metacarpals show swollen proximal part. Further its shaft is greatly reduced from proximal swollen part. The maximum dimensions at proximal end are 12 cm and 8 cm. The proximal part of metacarpal show biconcavity on articular surface, both cochleae are biconcave. One cochlea is much greater than other (Figure 3). A pair of very small femora (MSID-228, MSID-229) is also found in association with holotype animal in the same site and same formation show last stage pregnancy and may belong to son/daughter of Pakitherium shagalai mother. The femur expands less toward the proximal end. The femur head is ball like. There are two tuberosities/trochanters on the anterior and posterior side of proximal femur just close to femur head. Dorsally the head and other part of proximal femur show slight convexing arc shape. It may belong to embryo babe/child of Pakitherium shagalai. What is the reason for the death of both mother and her babe/child? However their association shows the daughter/son in mother belly due to pregnancy in Pakitherium shagalai. Further the size and development of femora show the middle to late stage embryo developments.
4. New Baluchithere Rhinoceros from South Punjab
Systematic paleontology of Buzdartherium gulkirao is as follows:
Buzdartherium  ;
Buzdartherium gulkirao  ;
Buzdartherium gulkirao a new genus and species based on tusk like incisor tooth, premolar tooth, tooth cross section, vertebrae, ribs, spines, proximal humerus, ulna, proximal pubis, pubis cross section, proximal ischium, ischium cross section, femur, carpal/astragalous/tarsal, metacarpal/metatarsal, phalanges, and ungual/toe with some bone pieces (Figure 3) collected from ferruginous conglomeratic beds (just below the 5 - 10 m thick silica sand beds) of Oligocene Chitarwata Formation in Taunsa-Gulki section of Dera Ghazi Khan District (Punjab). The etymology of Buzdartherium honor the Buzdar tribe and species name B. gulkirao honor the Gulki locality and Rao M. Ayub-with his kind cooperation this discovery was made. The fossils are hosted in the Museum of Geological Survey of Pakistan, Quetta. Buzdartherium gulkirao shared with Rhinocerotoidea on the basis of enormous thick and long canine (tusk like) like incisor, the huge and gigantic size and shape of ribs and limb bones. Buzdartherium gulkirao characterized by enormous thick and oval shaped cross section of long canine (tusk like) like incisor which externally hosts the subparallel keel like polished fibrous, dorsoventrally elongated structures, oval shaped premolar and sickle shaped large ungula. The close occurrence, relevant sizes and no duplication of thirty seven holotypic specimens MSM-1-Taunsa to MSM-37-Taunsa, tells their association with one individual. The canine like 1st incisor root is much thick and massive while crown show light brown enamel. Incisor tooth is stout and long. Its cone is broken but its large diameter and massive root morphology show its position as 1st incisor. This incisor presents high specialization and includes parallel keel like fibrous dorsoventrally elongated structures on polished enamel external surface. The first cheek tooth is collected which have oval

shaped. One partial centrum may belong to thoracic region with 14 cm preserved length. The preserved posterior/anterior articular surface of centrum with plano-convexo structures is partially eroded and seems to be set obliquely. The other fragment of centrum have no central hollow cavity. The ribs are thick and large again show its assignment to huge rhinoceros. The rib has two facets for articulating with vertebrae. The rib cross section is nearly plain on one side while convexing in other side and convexing line set obliquely from middle to outer side. One curved plate having a head like tuberosity (3 cm high, 7 cm wide and 10 cm long) may belong to proximal humerus. The other plate (11 cm width and preserved length is also 11 cm) may belong to part of ilium and acetabulum because plate has groove like acetabulum. The proximal pubis/ischium has a concave groove for acetabulum or for the adjustment of femur. An oval cross section of pubis/ischium is also collected which shows 4 cm thick and 9 cm wideness, the length preserved is about 10 cm. A proximal ulna having half lunate type preserved groove (11 cm * 8 cm) for adjustment of humerus condyle and some olecranon part is preserved. Dorsally it is triradial. Ulnar cross section have central hollow of 4 cm in dia. The peripheral bone is 1 cm to 2.5 cm thick. A proximal femur with its head (8 cm) is also preserved. The femur expands less toward the proximal end. The femur head is a ball like. There is a prominent ridge on the posterior side just close to femur dorsal surface. Dorsally the head and other part of proximal femur are weathered. The dorsal surface of proximal femur has 14 cm length and width may be 10 - 12 cm. The preserved length of femur is about 15 cm. The lateral surface of femur is convex like. It has circular hollow in the centre of bone cross section and this hollow has thick peripheral bone. The hollow has 6 cm in dia and peripheral bone has 1 cm to 2.5 cm thick layer. The proximal pubis and ischium has a groove for acetabulum. The large size of bones, spines, manus/pes bones and associated ungual/toe show their assignment to baluchithere. The small egg like material found with this assemblage may belong the eucrocodiles or snake eggs or the osteoderms or coprolite of Rhinoceros.
5. Early Horses (Perissodactyls) from Balochistan
Systematic paleontology of Mirvitakri haji is as follows:
Mirvitakri new genus;
Mirvitakri haji new species;
Mirvitakri haji, a new genus and new species of an old horse based on holotypic partial lower jaw including posterior dentary with angular process (MSM-141-4s) (Figure 4). It is found from the Latest Cretaceous terrestrial Vitakri Lameta Formation of Vitakri area, Barkhan District, Balochistan. Genus name Mirvitakri is honoring the Mr. Mir Muhammad Khetran of Vitakri village. Species name M. haji honoring the Haji Ahmad Khetran (field worker), of Rakhni Village, Barkhan district, and Haji Hafeez (Naib Qasid) and Haji Abdullah Jan, Haji Hameed Brohi, Haji Behram Khan and Haji Irfan (drivers) of Geological Survey of Pakistan, Quetta, Balochistan for excellent cooperation and services during most of the fieldworks in the Sulaiman and Balochistan. Holotypic specimen is housed in the museum of Geological Survey of Pakistan, Quetta. The specimen being rounded angular and long nature of dentary it is supposed to be a horse. This extinct horse seems to be small just more than a meter in length. The angular and posterior dentary formed rounded shape. The posterior dentary is transversely thin and show rounded angular profile of lower and posterior views. The preserved posterior dentary angular portion is about 6 cm anteroposteriorly long, 3 cm dorsoventrally high and transversely about 1 cm thick. Due to The lower back of dentary shows the rounded process emerged as angular for the attachment to upper jaw. This fossil of mammal (old horse) is the oldest in Pakistan.
Systematic paleontology of Bolanicyon shahani is as follows:
Bolanicyon shahani ;
Bolanicyon shahani a new genus and new species previously reported as large quettacyonid , but now expected to be a horse due to long dentary and rounded angular. Bolanicyon shahani is based on holotypic dentary with teeth MSM-1068-Western Mach (Figure 4), found at the coal mining at depth of about 500m in the Early Eocene Toi Formation of Gishtari area southwestern Mach, Bolan, Balochistan. Genus Bolanicyon is named after the Bolan river and district of Balochistan. The species name Bolanicyon Shahani honor the coal miner Gul Zaman Shahani who provided the holotypic specimen. Holotypic specimen is housed in the museum of Geological Survey of Pakistan, Quetta. Its 6 molar dentitions (Figure 4) with angular bone are well preserved while the anteriormost portion including long diastema including one canine tooth and further ahead incisors were destroyed. The teeth size increasing posteriorly. Further the transverse thickness of total preserved dentary is increasing backward or posteriorly. The preserved dentary is about 16 cm long and more than 1 cm thick and maximum thick at angular is about 2 cm. It is a small may be about 1 meter in length and also extinct horse. This mammal (old horse or Quettacyonidae) is among the oldest in Pakistan.

Saraikisaurus minhui ;
Saraikisaurus minhui new genus and species based on dentary, collected from Topkinwa 16 locality in the latest Maastrichtian Vitakri Lameta Formation of Fort Munro Group, Barkhan district, Balochistan. Fossil is hosted in the museum of Geological Survey of Pakistan, Quetta. Genus Saraikisaurus named after the local language Saraiki. Species name S. minhui honors the Prof. Dr. Min Huh of Korea. The closeness of the sockets of Saraikisaurus minhui matches with the pterosaur fossil from the Cretaceous of India  which is being referred to it. Saraikisaurus minhui shared with Pterodactyloidea as beak like light, thin, spongy, slender and elongated dentary ramus showing large pterosaur. Saraikisaurus minhui characterized as closeness of teeth and a few overlapped while most of the coeval pterosaurs have far spaced teeth on mandibles and jaws.
Description is as follows. Teeth are anteroposteriorly long and transversely compressed, oval to suboval, heterodont, very close to each other and mostly overlapped and obliquely oriented having direction from anterolaterally to medioposteriorly. The slender partial dentary ramus length is 5.8 cm, height is 2 cm and width is about 1 cm. The first tooth on preserved dentary beak ramus is 6 mm anteroposteriorly and 4 mm transversely wide, the second tooth is 8 mm anteroposteriorly and 4 mm transversely wide, the third tooth is 6 mm anteroposteriorly and 4 mm transversely wide, the fourth tooth is 7 mm anteroposteriorly and 4 mm transversely wide, the fifth tooth is 9 mm anteroposteriorly and 5 mm transversely wide, the sixth tooth is small in size and may showing replacement tooth, the tooth seven is 4 mm anteroposteriorly and 3 mm transversely wide and the eight tooth is 6 mm anteroposteriorly and 4 mm transversely wide. These measurements reveal that the transverse widths are mostly constant and also half of anteroposteriorly length. All the teeth crown are eroded. Closeness of the sockets represents a large number of teeth in Saraikisaurus minhui. The teeth central cavity and peripheral bone are dominantly exposed as cross section. The closeness of sockets and teeth of Saraikisaurus minhui differ from the Cretaceous pterosaurs from Cretaceous of Eastern England , Cearadactylus atrox  from the Early Cretaceous of Brazil, Jianchangnathus robustus  from middle Jurassic to Early Cretaceous of Lioning China, pterosaur oval to suboval/subcircular teeth from mid Cretaceous of Brazil , and lower Cretaceous of Brazil , while the size of teeth of Saraikisaurus minhui matches with the above mentioned pterosaurs. Saraikisaurus minhui is a toothed pterosaur supporting the criteria that the toothed pterosaurs continued upto end Cretaceous mass extinction. Further three or four elongated footprints (but not certain) of Anmolpakhi alleni pterosaurs are also found with the latest Maastrichtian titanosaur manus footprint found from the Sur Muzghai site (pl see detail in the following subtitle 14.3).

14. Footprints and Tracks of Dinosaurs from Pakistan
Footprints and tracks of stocky titanosauriforms or basal titanosaurs, and two groups of titanosaurian sauropods, small and large theropod dinosaurs were found from the Mesozoic strata of Pakistan so far.
14.1. Footprints and Tracks of Titanosauriforms or Basal Titanosaurs Confronted by a Large Theropod Found from the Late Jurassic of Malakhel Area, Pakistan
Trackways of the titanosauriforms (basal titanosaurs or ornithischian) Malakhelisaurus mianwali   confronted by a theropod Samanadrinda, found (Figure 7) from the Late Jurassic (150 - 145 Ma, few beds below Jurassic-Cretaceous boundary) uppermost Samanasuk Limestone of Baroch Nala, Malakhel area, Mianwali District, Punjab. The tracks pattern shows three parallel trackways (Figure 7) indicating a herd. The trackways have a relatively wide gauge (internal trackway width of 0.4 m), asymmetric D shaped manus (about 50 cm × 70 cm) without unguals (autapomorphy of titanosaurs), a large circular symmetric pes with five digits (about 1.3 m × 1.3 m) which have large oval anteriorly directed toes on digits II, III, IV and reduced outer digits I and V, and feeble W-shaped heel. The distinctive toe impressions clearly indicate three portions with a central oval-shaped ungual which is enveloped by a sole cushion of about 5 cm width or thickness, anteriorly encased by a broad reversed U-shaped hoof (Figure 7). The heteropody ratio is 1:4.5. Based on the gauge of the trackway, the hip height is estimated at 4 - 5 m. Trackmakers steps made depressions by compressing cohesive calcareous mud which extruded on the sides. Later on filled by clayey mud. During diagnosis these rocks became hard which is thrusted and exposed by tectonics and erosion.
14.2. Footprints and Tracks of Stocky and Slender Titanosaurs Found from the Latest Cretaceous Strata of Pakistan
Footprints of the stocky titanosaur Pashtosaurus zhobi   were found from the Latest Cretaceous Vitakri Lameta sandstone beds of Sur Muzghai Locality, opposite Musafarpur Thana, Qila Saifullah district, Zhob division, Balochistan. The first trackway shows left and right pes and manus, and the second trackway shows left and right manus (glided) and right pes (Figure 7). Third trackway has minor indication. The ichnite indicates a herd movement, a relatively narrower gauge (0.20 - 0.25 cm internal trackway width), asymmetric D-shaped manus (50 - 55 cm × 70 - 75 cm) without claws (autapomorphy of titanosaurs), and a giant circular symmetric pes with five digits (1.27 m long and 1.28 m wide), with distinctive large oval anteriorly directed toes (all along the front edge) on digits II, III and IV, and reduced outer digits I and V, and well developed W-shaped heel. The central oval ungual is enveloped by a fleshy sole cushion which is anteriorly encased by a U-shaped hoof. The central digit III is inserted in a forward position which creates a W-shaped heel like in extant camels. One manual imprint shows marks of D-shaped metacarpals I, II, III, IV and V. The heteropody ratio is about 1:4.5. The footprints shape matches with the Late Jurassic Malakhel site. The tracks are referred to titanosaurs rather than to stegosaurs. These footprints are very interesting show D-shaped manus affinity to titanosaurs and large circular pes with large oval ungual and anteriorly covered by hoof show affinity to large thyrophoran ornithischian like stegosaurs and hadrosaurs. Titanosaurs have a symmetric five digits pes with toes on central digits II, III, IV and reduced outer digits I and V without toes, while stegosaurs and hadrosaurs have a symmetric pes with only three digits. The pes of titanosaurs is very large while hadrosaurs and stegosaurs have a triangular pes of moderate size. Unguals are full oval in titanosaurs, and half oval and posteriorly blunted in stegosaurs and hadrosaurs. Titanosaurs have a five digits manus without claws while stegosaurs and hadrosaurs have a five digits manus with two unguals (Peter Galton, pers. comm.). Trackmakers steps made depressions by compressing cohesive sandy mud which extruded on the sides. Later on filled by thin clay and then thick sand. During diagnosis the sand formed sandstone and clay formed shale, which are thrusted later on by tectonics and exposed by erosion. Further one D-shaped manus of Pashtosaurus zhobi found in level 2 shows clear impressions of five separated metacarpals (Figure 7). The skin impression found in freshly natural cast formed by filled sand in footprint of the most advanced titanosaur Pashtosaurus zhobi excavated from this site. This sole skin impression reveals tubercles, pits, wrinkles, whorl, loop and contoured textures (Figure 7).
The natural cast of pes footprint of Dgkhansaurus maarri new genus and species based on footprint (Figure 7) is a slender titanosaur found from the latest Cretaceous upper part of Pab Formation (=Vitakri Lameta Formation) of Maarri peak locality, Rajanpur district, Dera Ghazi Khan Division, South Punjab. The Dgkhansaurus is pronunciated as D. G. Khan. Saurus. This genus is named on the name host Dera Ghazi Khan (D. G. Khan) Division and species name established honor the host locality namely Maarri. This pes cast was discovered by Nasir Somro . The pes of Dgkhansaurus maarri is relatively long and thin, slender and it consists of sickle shaped unguals (on digit I, II, III, IV) (Figure 7). While digit V is reduced and has reduced or no ungual. The Dgkhansaurus maarri have slender and laterally directed toes or unguals while in some other cases but outside Pakistan have slender and anteriorly directed toes or unguals. Trackmakers steps made depressions by compressing cohesive sandy mud which extruded on the sides. Later on filled by sand. During diagnosis the sand formed sandstone, which are thrusted later on by tectonics and upper beds having cast of footprints exposed by erosion.
There are two types of pes unguals and pes outlines of footprints showing slender and stocky titanosaurs. The slender titanosaurs are represented by elongated pes with relatively small-sized sickle-shaped unguals (resemble to sauropod saurischians), and the stocky titanosaurs are represented by rounded or circular pes with relatively large-sized oval-shaped anteriorly directed unguals (resemble to sauropod saurischians but also differentiated). This hypothesis of two groups of titanosaurs is also assisted and verified by bone fossil records especially large-sized oval-shaped rugose ungual bone fossils reported from Pakistan. Like these large oval and rugose unguals (previously as oval osteoderms) were also reported from Malawi, Argentina and India. Now it needs finding of complete pes bones. Dgkhansaurus maarri is a derived slender titanosaur, while Pashtosaurus is stocky titanosaur and Malakhelisaurus is stocky titanosauriforms.
14.3. Footprints of Pterosaurs from Sur Muzghai Site, Zhob Division, Balochistan, Pakistan
The footprints of Anmolpakhi alleni flying reptile pterosaurs (Figure 7) found on level 2 (third bed just below Pashtosaurus zhobi titanosaur ichnotype bed) of Sor Muzghai locality, Musafar Pur Thana area, Qila Saifullah District, Zhob division, Balochistan Province, Westernmost Sulaiman basin. This ichnite is hosted by the latest Cretaceous Vitakri Formation (upper part of Pab sandstone). The pterosaur footprints are associated with asymmetric D shape manus footprint of Pashtosaurus zhobi titanosaur. Manus and pes footprints of Anmolpakhi alleni are recorded. Genus name Anmolpakhi derived from Urdu and Saraiki word Anmol mean “can not be purchased”, while Pakhi in Saraiki language mean flying animal/ birds. The species name A. alleni is after Mr. Nicholas Allen British Journalist which helped a lot for the preparation of 3-D models and preservation of Level 5 ichnotype of Pashtosaurus zhobi from this site. The ichnite of Anmolpakhi alleni is located at 30˚57'36" North and 69˚08'24" East in situ in Sor Muzghai site. The pterosaur footprints are about 20 - 30 cm long and 8 - 10 cm wide representing hind and fore limb footprints. The pterosaur footprints are parallel with each other. These tracks match closely with pterosaur footprints from the Cretaceous of South Korea. These are found only about one meter width of small exposure of sandstone bed, further excavation reveal better results. The depth of footprints/tracks is very small showing light weight pterosaurs (Figure 7).
14.4. Trackways of Large and Small Theropod Dinosaurs from the Late Jurassic Strata of Malakhel Area, Pakistan
The Samanadrinda surghari   large theropod trackway including 5 footprints in a single trackway (Figure 7) confronted by a herd of Malakhelisaurus mianwali titanosauriforms (early titanosaurs or may be ornithischian) were found from the Late Jurassic (150 - 145 Ma) upper successions of Samanasuk Limestone of Baroch Nala, Malakhel area, Mianwali District, Punjab. Limestone dips 52˚ west and strike north 50˚ east. The trackway pace and stride and straight alignment of pes print reveal a running large bodied theropod attacked obliquely on a herd of Malakhelisaurus mianwali. This site reveals the very large theropod moved and attacked as solitary. The measurement of the first preserved left footprint shows following analysis. Very Large (72 cm long; 60 cm broad) tridactyl footprint have digit length ratios III/II = 1.45 and III/IV = 1.1, respectively. The length to width ratio is about 1.2. Phalangeal pads visible in digit II are two, in digit III are three, and in digit IV are four. Toes thick, sharply tapered, digit III is slightly larger than digit IV, while digit III is considerably larger than digit II. It means digit III and digit IV are subequal. Divarication angle of digits II-IV is 50˚. On comparison with  data, the Samanadrinda surghari footprints characters and ratios are different. Samanadrinda may be an ancestor of ceratosaur abelisauroids while Himalayadrinda is the ancestor of noasaurids. Samanadrinda surghari divarication angle about 50˚ are close to Anomoepus sp. The footprints of Samanadrinda from Pakistan are larger than giant theropod footprint from the Early Jurassic of Poland  and also larger than Indian theropod footprints . Applying  revised formula of H= 4.586 L, the height upto hip is 3.3 m and applying  formula H = 4W, the height become 2.4 m. In average height is 2.85 m. It belongs to a biped that has over 2.5 m height at the hip and 10 - 12 m long. Footprints formation process is as follows. The theropod stepped on a thick cohesive calcareous mud layer, its foot sinking to the top part of an underlying calcareous mud layer, producing a negative relief. The calcareous mud was squeezed out sidewise. Later clayey mud layer filled the footprints depression and other succession continued. Diagenesis turned the calcareous mud into limestone and the mud layer into shale. Shale and upper sequences eroded after tectonic uplift. The footprints on hard beds remained preserved and exposed after erosion of upper beds by tectonic uplift which tilted host bed more than 50˚.
400 m southward from the site of Malakhelisaurus mianwali titanosauriforms confronted by a Samanadrinda surghari theropod ichnotype, two close tracks of a couple of Himalayadrinda potwari  small bodied theropods (Figure 7) found from the middle Jurassic (170 - 160 Ma) Samanasuk limestone of Baroch Nala, Malakhel area, Mianwali District, Punjab. The host limestone bed is few beds below the Samanadrinda (+Malakhelisaurus) host bed. Limestone dips 52˚ west and strike north 50˚ east. The tracks of Himalayadrinda potwari was about 20 m high from nearby ground. The convergence of two tracks of small theropods shows interaction behavior. These tracks are very significant for early evolution and diversification of small theropods. This site reveals that smaller theropod moved as herd or at least a couple while large theropod moved as solitary. The tridactyle footprints are small (approximately 15 cm long; 12 cm broad) with the ratio of digit III/digit II = 1.4 and the ratio of digit III/digit IV = 1.0. The length to width ratio is about 1.2. Toes slender, sharply tapered, digit III and digit IV are subequal while digit III is considerably larger than digit II. The divarication angle of digits II - IV = c. 70˚ - 90˚. The last toe or claw turned inward. According to comparison with  data, this Himalayadrinda is unique small theropod. Reference  mentioned interdigital angle upto 50˚ of theropod footprints from Brazil but Himalayadrinda from Pakistan have angle upto 90˚ (Figure 1). While  mentioned interdigital angle upto 80˚ of footprints which is close to Himalayadrinda footprints. This study reveals that the Himalayadrinda potwari (divarication angle of digits II – IV = c. 70˚ - 90˚) is the ancestor of noasaurs theropods while Samanadrinda surghari (divarication angle of digits II - IV = c. 50˚) is the ancestor of abelisauroid theropods. Applying  revised formula of H = 4.586 L and  formula H = 4 W, the general height of Himalayadrinda is about 0.5 m. It belongs to a biped that has 0.3 - 0.5 m height at the hip and 1.0 to 1.5 ms long. This close affinity of Himalayadrinda small theropods with Brazil (South America) like titanosaurs and mesoeucrocodiles again shows paleobiogeographic affinity with South America. This close affinity is due to common Gondwanan early seed radiations and heredity resulted at Early Cretaceous. Trackmakers steps and digits made depressions by compressing cohesive

15. Comparison of Recognized Four Titanosaur Taxa from Indo-Pakistan Subcontinent with Four Titanosaur Taxa of Madagascar
Indo-Pakistan titanosaurs were reported from the latest Maastrichtian (67 - 66 Ma) Vitakri Lameta Formation . References   recognized four titanosaur taxa from India. On the basis of diverse cranial, vertebral and limb materials from Pakistan, the reference  also recognized four coexisting titanosaur taxa such as Gspsaurus pakistani  (including a mid caudal of Antarctosaurus) the thick lense shaped proximal tibia bearing medium bodied Gspsaurinae; and Saraikimasoom vitakri  (including two caudals and a tibia of Titanosaurus blanfordi) the subcircular proximal tibia bearing small bodied Saraikimasoominae gspsaurids, and Pakisaurus balochistani  (including one vertebra of Titanosaurus indicus; one robust straight tooth of Titanosaurus rahioliensis) the thin bone tibia bearing the large sized pakisaurid; and filled the gaps in Isisaurus colberti like femur, tibia, fibula and metacarpal. All these four recognized taxa of Indo-Pakistan have synapomorphies of poripuch  the most derived titanosaurs which have procoelous all the anterior, middle and distal caudals except the first caudal in stocky taxa . There was longstanding issue and controversy that how many valid titanosaur existed in the latest Cretaceous of Indo-Pakistan. Now it became certain, consistent and confident by finding of four types of tibiae from Pakistan (especially proximal tibiae-unique gifts in global world). Four type of tibiae (Figure 7) including two diverse stocky tibiae like rounded proximal tibia of Saraikimasoom with equal transverse and anteroposterior width, and anteroposteriorly lense shaped proximal tibia of Gspsaurus; and two diverse slender tibiae with low transverse thickness like transversely thin proximal tibia of Pakisaurus with lateral fibular ridge as arc shaped ended just below the cnemial crest, and transversely thin proximal tibia of Isisaurus with lateral fibular ridge as parallel/subparallel to anterior profile of cnemial crest and shaft. These four types of tibiae and associated diverse cranial and postcranial elements are discovered from Pakistan belonging to four taxa of Indo-Pakistan subcontinent , solved the longstanding issue of number of titanosaur’s taxa from Indo-Pakistan. Besides titanosaurs, two large theropods Vitakridrinda  and Vitakrisaurus   and two large sized mesoeucrocodiles Induszalim   and Pabwehshi , and pterosaur Saraikisaurus minhui were also discovered from Pakistan.
The Maastrichtian Vitakri Lameta Formation (terrestrial red muds, and sandstone) of Indo-Pakistan correlated with the Maastrichtian Maevarano Formation (terrestrial red muds, and sandstone) of Madagascar. Further four coexisting latest titanosaurs hosted by Vitakri Lameta Formation also match closely with four latest titanosaurs hosted by Maevarano Formation. Further the finding of diverse 4 types of caudal vertebrae and diverse 4 types of tibiae and other diverse skeletal elements from Pakistan belong to four poripuch titanosaur taxa which provided the facility for correlation and comparison with Malagasy titanosaur fossils. This interpretation is consistent with the four coexisted latest titanosaurs from Indo-Pakistan peninsula. From Madagascar, the titanosaurian three taxa identified on the basis of diverse caudal vertebrae and fourth titanosaur taxon identified on the basis of slender tibia with lateral fibular articular ridge forms arc shape and ended just below the cnemial crest. Because four types of tibia associated with typical vertebrae from Pakistan. First, the large caudal vertebra UCB 92829 of Titanosaurus madagascariensis  from Madagascar matches closely with Saraikimasoom of Indo-Pakistan peninsula due to strong ventral reduction of caudal. Second, the other small caudal vertebra UCB 92305 of Titanosaurus madagascariensis  from Madagascar may be close to Isisaurus (Sulaimanisaurus) from Indo-Pakistan due to almost square shape (although slightly broad) and no ventral reduction. Third, the caudal vertebra FMNH PR 2209 of Rapetosaurus  from Madagascar show close resemblance to Gspsaurus from Indo-Pakistan landmass due to slightly tall and ventrally reduced caudal vertebra. Fourth, the transversely narrow slender tibia with arc shaped lateral fibular condylar ridge ended just below the cnemial crest, humerus and teeth of Rapetosaurus  from Madagascar matches closely to Pakisaurus from South Asia. This shows the dual affinity (chimera) of fossils of Titanosaurus madagascariensis  and also the dual affinity (chimera) of fossils of Rapetosaurus krausei .
Indo-Pakistan subcontinent now occupied and covered South Asia while the present research revealing previous contact with Gondwana is consistent with Indo-Pakistan paleobiogeographic hypothesis. The latest Cretaceous titanosaurian sauropods of Indo-Pakistan show paleobiogeographic affinity to Madagascar, revealing earliest Cretaceous contact of Indo-Pakistan landmass with Madagascar, instead of present contact with Asia. Indo-Pakistan started northward journey at Early Cretaceous (135 Mya) and continued journey as island during most of the Cretaceous. Indo-Pakistan plate first time collided with Asia during the latest Cretaceous (67 - 66 Mya) just before or at the time of Cretaceous-Paleogene mass extinction. This northward migration from southern hemisphere to northern hemisphere of earth via equator is responsible for the geological, tectonics, paleontological, evolutionary and morphological changes in Indo-Pakistan landmass.
