The histology of rhynchosaur (Diapsida, Archosauromorpha) ankylothecodonty. [PDF]

open access: yesJ Anat
Dental 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]

open access: yesRoyal 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]

open access: yesPeerJ, 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

A new stem saurian reptile from the late Permian of South Africa and insights into saurian evolution [PDF]

open access: yesSwiss Journal of Palaeontology
The 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

Susceptibility of Gecko Cell Line for Cultivation and Adaptation of Infectious Bursal Disease Virus as an Experimental Vaccine. [PDF]

open access: yesVet Med Sci
First successful cultivation of IBDV on reptile‐derived Z1 cells yields high‐titre virus and induces immunity in chickens. This scalable, egg‐free platform offers a promising alternative for vaccine production, leveraging evolutionary kinship between reptiles and birds for next‐generation poultry disease control.

A new sphenodontian (Diapsida: Lepidosauria) from the Upper Triassic (Norian) of Germany and its implications for the mode of sphenodontian evolution [PDF]

open access: yesBMC Ecology and Evolution
The 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

The holotype of the basal archosauromorph Prolacerta broomi revisited [PDF]

open access: yesActa Palaeontologica Polonica, 2023
Prolacerta broomi is one of the most important of fossil reptiles. First considered as one of the earliest members of squamates, this basal archosauromorph has been used as a model for diapsid morphological evolution ever since its discovery, playing ...

Trifold origin of the reptilian ear ossicle and its relation to the evolutionary modification of the temporal skull region. [PDF]

open access: yesJ Anat
The columella‐complex in reptile middle ears involves the footplate, columella shaft, and extracolumella. The latter is partly of quadrate developmental origin, whereas the footplate derives from the mesodermal otic capsule, the shaft and another part of the extracolumella from the hyoid arch.

CARINTHIASUCHUS KANDUTSCHI, A NEW ARCHOSAUR (REPTILIA: DIAPSIDA) FROM THE TRIASSIC OF AUSTRIA

open access: yesRivista Italiana di Paleontologia e Stratigrafia
A partial skeleton of a small reptile with a distinctive maxilla, dentition, caudal vertebrae and osteoderms from the marine Partnach Formation (Ladinian-earliest Carnian) near Jadersdorf (Gitschtal, Hermagor) in the Gailtal Alps of Carinthia (Austria),

Colobops: a juvenile rhynchocephalian reptile (Lepidosauromorpha), not a diminutive archosauromorph with an unusually strong bite [PDF]

open access: yesRoyal Society Open Science, 2020
Correctly identifying taxa at the root of major clades or the oldest clade-representatives is critical for meaningful interpretations of evolution. A small, partially crushed skull from the Late Triassic (Norian) of Connecticut, USA, originally described
