The postcranial skeleton of the reptile Gephyrosaurus bridensis is described. The material was extracted from the Lower Jurassic fissure infillings of South Wales and comprises the broken and dissociated bones of many different individuals. The skeleton, like the skull, retains many primitive features which justify the inclusion of Gephyrosaurus within the Eosuchia. A comparison of the skeleton with that of other genera supports the conclusion that Gephyrosaurus represents a separate eosuchian…

A PARTIAL SKELETON OF THE TRITHELEDONTID PACHYGENELUS ( THERAPSIDA : CYNODONTIA ) by
TLDR
A specimen of the tritheledontid Pachygenelus is described which has most of the skull and vertebral column, a complete shoulder girdle, andMost of the forelimb, closely comparable to those of Massetognathus and Eozostrodon.
Morphological evidence for bipedalism in the Late Triassic prolacertiform reptileLangobardisaurus
TLDR
Morphological evidence and size-related criteria are consistent with a facultative digitigrade configuration while standing erect, and the elongation of the neck, a hallmark of the prolacertiforms, may have assisted these efforts, as in Chlamydosaurus.

TLDR
This study shows how developmental osteology can help in the identification of gecko bo~es by describing the appendicular skeleton and its calcification at 3 ages in Bunopus tuberculatus.

Rhynchocephalians (Diapsida: Lepidosauria) from the Jurassic Kota Formation of India
TLDR
New sphenodontian material from the Jurassic Kota Formation of peninsular India indicates the presence of a primitive pleurodont lepidosauromorph similar to the basal rhynchocephaliansGephyrosaurus and Diphydontosaurus from Britain.

A bird-like skull in a Triassic diapsid reptile increases heterogeneity of the morphological and phylogenetic radiation of Diapsida
TLDR
The phylogenetic position of drepanosaurids indicates the presence of archaic Permian clades among Triassic small reptile assemblages and that morphological convergence produced a remarkably bird-like skull nearly 100 Myr before one is known to have emerged in Theropoda.
Postcranial Osteology of Azendohsaurus madagaskarensis (?Middle to Upper Triassic, Isalo Group, Madagascar) and its Systematic Position Among Stem Archosaur Reptiles
TLDR
Using the most comprehensively sampled phylogenetic analysis of early archosauromorphs, the clade encompassing Azendohsaurus, Trilophosaurus, Spinosuchus, Pamelaria, and Teraterpeton is found, and it is suggested that most major divergences within this group occurred in the Triassic.
Fossil lizards from the Jurassic Kota Formation of India
TLDR
A lizard assemblage from the Upper Member of the Kota Formation of peninsular India, usually considered to be of Early–Middle Jurassic age, is reported, providing evidence that iguanians had begun to diversify before the break-up of Pangea.
