The phylogenetic relationships of basal archosauromorphs, with an emphasis on the systematics of proterosuchian archosauriforms [PDF]

open access: yesPeerJ, 2016
The early evolution of archosauromorphs during the Permo-Triassic constitutes an excellent empirical case study to shed light on evolutionary radiations in deep time and the timing and processes of recovery of terrestrial faunas after a mass extinction ...

open access: yesFrontiers in Earth Science, 2017
Over the past two decades, a wealth of marine and terrestrial reptiles, including protorosaurian archosauromorphs, has been described from Triassic shales and limestone layers in southern China.

Morphology of the temporal skull region in tetrapods: research history, functional explanations, and a new comprehensive classification scheme

open access: yesBiological Reviews, Volume 96, Issue 5, Page 2229-2257, October 2021., 2021
ABSTRACT The morphology of the temporal region in the tetrapod skull traditionally has been a widely discussed feature of vertebrate anatomy. The evolution of different temporal openings in Amniota (mammals, birds, and reptiles), Lissamphibia (frogs, salamanders, and caecilians), and several extinct tetrapod groups has sparked debates on the ...

Anatomia, paleobiologia e filogenesi di Macrocnemus bassanii Nopcsa 1930 (Reptilia, Protorosauria) [PDF]

open access: yes, 2016
Macrocnemus bassanii is a Middle Trias diapsid reptile that belongs to the group of the Protorosauria. Its main features are the elongated stiff neck and the hindlimbs which are much longer than the forelimbs. The aim of this study is to clarify some aspects of its anatomy that are still controversial, like the structure of the nasal region, the ...

Forged soft tissues revealed in the oldest fossil reptile from the early Permian of the Alps

open access: yesPalaeontology, Volume 67, Issue 1, January/February 2024.
Abstract Tridentinosaurus antiquus represents one of the oldest fossil reptiles and one of the very few skeletal specimens with evidence of soft tissue preservation from the Cisuralian (Early Permian) of the Italian Alps. The preservation and appearance of the fossil have puzzled palaeontologists for decades and its taphonomy and phylogenetic position ...
