The evolutionary success of mammals is rooted in their high metabolic rate. A high metabolic rate is sustainable thanks to efficient food processing and that in turn is facilitated by precise occlusion of the teeth and the acquisition of rhythmic…

Protocetid cetaceans were first described from the Eocene of India in 1975, but many more specimens have been discovered since then and are described here. All specimens are from District Kutch in the State of Gujarat and were recovered in deposits…

The family Remingtonocetidae is a basal family of Eocene cetaceans only known from near shore marine environments of India and Pakistan. We describe a new skull for Remingtonocetus harudiensis which elucidates the anatomy and functional morphology of…

Discoveries of three species of Eocene sirenians in District Kachchh, State of Gujarat, India, are reported. A species of the protosirenid Protosiren is represented by cranial and postcranial material, and the halitherime dugongid Eosiren is…

Procreodi is an order of Paleocene and Eocene mammals thought to lie at the base of the radiation of the paraphyletic condylarths.' Taxa within the order have been linked to the origins of other condylarth groups, and of some living orders. Within…

Multituberculate and eutriconodontan endocasts differ from those of primitive therian mammals in their lack of visible midbrain exposure oil the dorsal side and in having a vermis-like triangular bulge (recognized herein as the cast of a large…

A collection of fossil material from Eocene deposits of Pakistan includes remains belonging to various taxa of actinopterygian fishes. The material comes from predominantly freshwater deposits, as well as a few marine deposits, in the Kuldana…

The skulls and isolated tympanics are described for the earliest whales, pakicetids, from the H-GSP Locality 62 in the Ganda Kas area in Northern Pakistan. Currently three pakicetid genera are known: Pakicetus, Ichthyolestes, and Nalacetus.…

The early Eocene of Panandhro Mine (northwestern India) has produced a rich snake fauna largely dominated by palaeophiids. Three families are present: Palaeophiidae, ?Madtsoiidae or Boidae, and an indeterminate family of Colubroidea. The…

The thick (> 4000 m) coarsening-upward terrestrial Neogene sequence of the Sulaiman Range (Middle Indus Basin, central Pakistan) is the western extension of the Siwalik outcrop belt of the Sub-Himalayas. The near-shore to terrestrial sedimentation in…

Examination of preserved skin from a duckbill dinosaur revealed disruption of the normal scale pattern and replacement by granulation tissue. Wrinkles radiating outward from the scar document wound contraction similar to that seen in modern injuries.…

In order to assess the presence of tuberculosis in Pleistocene bison and the origin of tuberculosis in North America, 2 separate DNA extractions were performed by 2 separate laboratories on samples from the metacarpal of an extinct long-horned bison…

Odontochelys semitestacea, the oldest known turtle, from the Late Triassic of China, shows a pathology. Sharply defined, focal depressions were noted on the articular surfaces of both humeri, documenting avascular necrosis. Diving habits of Mesozoic…
