The sauropod dinosaur, Barapasaurus tagorei, is known from the Early Jurassic Kota Formation (Sinemurian to Pliensbachian) of India. The taxon is represented by c. 300 bones that were found associated with large fossilized tree trunks and were collected from the interface of sandstone and mudstone units covering an area of c. 276 m 2 . The collection includes one partial skeleton; most of the remainder of the bones were disarticulated, disassociated and dispersed, but taphonomic analysis permits recognition of associated elements comprising several individuals. Skeletal anatomy of Barapasaurus includes several teeth, vertebrae from the caudal cervicals rearward to the terminal caudals, and most elements of the appendicular skeleton. Barapasaurus is characterized by spoon-shaped teeth with bulbous bases and grooves on the anterolabial and posterolingual sides of the crown, coarse tubercles on the carina, acamerate cranial and dorsal vertebrae, lateral laminae of the middle and caudal dorsal neural spines composed of spinodiapophyseal and spinopostzygapophyseal laminae, neural canal of the mid-dorsal vertebrae opens dorsally through a narrow slit into a large cavity and sacrum with four co-ossified vertebrae. Phylogenetic analysis reveals that Barapasaurus is basal in comparison with Vulcanodon and is removed from Eusauropoda.

Changes in terrestrial vertebrate faunas during the Mesozoic

Summary The precise time-range of any terrestrial group is difficult to establish, due to the uncertainties of preservation and discovery and due to the difficulty of ascertaining the relative ages of faunas from different areas. Differences between such faunas may be due to ecological and zoogeographical factors as well as to age differences. Even when a relative time-sequence has been established, it is difficult to correlate this with the standard section for the period; this is particularly true for the Triassic faunas. As seen in the South African record, the climate became progressively hotter and drier from the Carboniferous Dwyka glaciation until the deserts of the Upper Triassic. The earliest Triassic fauna is a swamp fauna which still included elements of most of the more conservative, synapsid reptiles. During the remainder of the Triassic, these synapsids were gradually replaced by the evolving diapsids. The more primitive members of the Diapsida were themselves replaced in the Jurassic by more progressive members of the group. The earliest mammals, those of the Triassic and Jurassic, were probably homoiothermal though not viviparous. None larger than a cat is known until immediately after the disappearance of the dinosaurs. The reasons for this apparent inability of somewhat larger (e.g. pig-sized) mammals to co-exist with the dinosaurs are not obvious.
