Systematics and evolutionary history of proterosuchian archosauriforms
TLDR
The results obtained here suggest that the evolutionary history of the archosauriforms during the Early Triassic can be subdivided into a first phase characterized by the short-lived “disaster-clade” Proterosuchidae and a second phase that witnessed the initial morphological and probably palaeoecological diversification of the group.
The internal cranial anatomy of Champsosaurus lindoei and its functional implications
TLDR
The presence of the putative neomorphic bone is confirmed, which may be homologous with the pre-existing stapes, or developed through incomplete fusion of dermatocranial ossification centres, and geometric morphometric analyses of the semicircular canals suggest that Champsosaurus were well adapted for an aquatic lifestyle.
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.
Osteology and taxonomic revision of Hyphalosaurus (Diapsida: Choristodera) from the Lower Cretaceous of Liaoning, China
TLDR
Observations from a variety of growth stages reveal that significant ontogenetic change in the proportions of the body and limb bones occurred in both species of Hyphalosaurus.
An evaluation of the phylogenetic relationships of the pterosaurs among archosauromorph reptiles
TLDR
Critical evaluation of the analyses that produced these results suggests that the orthodox position retains far greater support and no close link can be established between pterosaurs and protorosaurs.
Diversity of diapsid fifth metatarsals from the Lower Triassic karst deposits of Czatkowice (southern Poland); functional and phylogenetic implications
Three morphotypes of the fifth metatarsal (MttV), one of the most informative bones of the postcranium, have been described herein from the Early Triassic karst deposits of the Czatkowice locality
Late Triassic Tanystropheids (Reptilia, Archosauromorpha) from Northern New Mexico (Petrified Forest Member, Chinle Formation) and the Biogeography, Functional Morphology, and Evolution of Tanystropheidae
TLDR
These fossils and others from Late Triassic sites in the American West suggest that tanystropheids underwent a previously unrecognized radiation in North America just prior to their extinction.
The Origin and Early Evolution of Sauria: Reassessing the Permian Saurian Fossil Record and the Timing of the Crocodile-Lizard Divergence
TLDR
A revision suggests a minimum fossil calibration date for the crocodile-lizard split of 254.7 Ma, and early archosauromorph growth strategies appear to be more diverse than previously suggested based on new data on the osteohistology of Aenigmastropheus.
Cranial anatomy of a new genus of hyperodapedontine rhynchosaur (Diapsida, Archosauromorpha) from the Upper Triassic of southern Brazil
TLDR
The cranial anatomy of the rhynchosaur previously known as Scaphonyx sulcognathus allows its assignment to a new genus Teyumbaita, suggesting that the group survived the end-Carnian extinction event.
