The histology of rhynchosaur (Diapsida, Archosauromorpha) ankylothecodonty. [PDF]
J AnatDental evolution is a major topic in vertebrate palaeontology and provides key insights into the evolutionary history of several amniote clades. This study investigates rhynchosaur ankylothecodonty within the broader evolutionary context of Archosauromorpha.

Growth patterns and life-history strategies in Placodontia (Diapsida: Sauropterygia) [PDF]
Royal Society Open Science, 2015 Placodontia is a clade of durophagous, near shore marine reptiles from Triassic sediments of modern-day Europe, Middle East and China. Although much is known about their primary anatomy and palaeoecology, relatively little has been published regarding ...

Systematics of putative euparkeriids (Diapsida: Archosauriformes) from the Triassic of China [PDF]
PeerJ, 2014 The South African species Euparkeria capensis is of great importance for understanding the early radiation of archosauromorphs (including archosaurs) following the Permo–Triassic mass extinction, as most phylogenetic analyses place it as the sister taxon

Inter-relações filogenéticas dos rincossauros (Diapsida, Archosauromorpha) [PDF]
, 2015 Rhynchosauria é um grupo basal de arcossauromorfos (Reptilia, Diapsida) encontrados em rochas triássicas de praticamente todo o mundo, que no Triássico Médio e início do Triássico Superior foram os principais componentes de muitas faunas continentais ...

Postcranial paleoneurology of the Diapsida [PDF]
Journal of Zoology, 1995 The relationships between the size of the spinal cord and the size of the neural canal, and between gross spinal cord anatomy and locomotor style, were documented in a wide range of living diapsids. Observed relationships were used to make predictions about spinal cord anatomy and about limb use and position in related fossil taxa.

A new phylogeny of ichthyosaurs (Reptilia: Diapsida) [PDF]
Journal of Systematic Palaeontology, 2017 The largest phylogenetic analysis of ichthyosaurs to date is presented, with 114 ingroup taxa coded at species level. Completeness of the taxa included varied from > 98% to < 2%; 10 taxa were removed a priori using Concatabominations due to incompleteness and taxonomic uncertainty.

Sexual dimorphism in Champsosaurus (Diapsida, Choristodera) [PDF]
Lethaia, 2004 Two nearly complete specimens of Champsosaurus (Diapsida, Choristodera) with distinctive morphologies, from the Tullock Formation (Early Paleocene) of northeastern Montana, USA, were described as different species. The limb bones of C. ambulator are more robust than those of C. laramiensis, indicating that C. ambulator was more adapted for walking than

A new stem saurian reptile from the late Permian of South Africa and insights into saurian evolution [PDF]
Swiss Journal of PalaeontologyThe evolutionary radiation of diapsid reptiles that includes all extant and most extinct reptiles is well-represented in the Mesozoic and Cenozoic fossil records, however, the earliest stages recorded in the Paleozoic Era are limited to comparatively few

A new sphenodontian (Diapsida: Lepidosauria) from the Upper Triassic (Norian) of Germany and its implications for the mode of sphenodontian evolution [PDF]
BMC Ecology and EvolutionThe Arnstadt Formation of Saxony-Anhalt, Germany has yielded some of Germany’s most substantial finds of Late Triassic tetrapods, including the sauropodomorph Plateosaurus and the stem-turtle Proganochelys quenstedti. Here, we describe an almost complete
