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

Royal 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

The braincase of Mesosuchus browni (Reptilia, Archosauromorpha) with information on the inner ear and description of a pneumatic sinus [PDF]

PeerJ, 2019
Rhynchosauria is a group of archosauromorph reptiles abundant in terrestrial ecosystems of the Middle Triassic. Mesosuchus is one of the earliest and basalmost rhynchosaurs, playing an important role not only for the understanding of the evolution of the

Bone histology and growth in Stenaulorhynchus stockleyi (Archosauromorpha: Rhynchosauria) from the Middle Triassic of the Ruhuhu Basin of Tanzania

Comptes Rendus - Palevol, 2016
Abstract The bone histology of non-archosauriform archosauromorphs is understudied but is important for tracing the evolution of growth in archosaurs and their closest relatives. Here, we describe the femoral and tibial histology of a single individual of Stenaulorhynchus stockleyi , a Middle Triassic rhynchosaur from Tanzania.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

Anatomical Record
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

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

Biological 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 ...

Osteohistology of hyperodapedontine rhynchosaurs from the Upper Triassic of Southern Brazil [PDF]

Acta Palaeontologica Polonica, 2015
The first osteohistological study focused exclusively on rhynchosaurs (non-archosauriform archosauromorphs), based on the hyperodapedontines Teyumbaita sulcognathus and Hyperodapedon sp., from the Upper Triassic of Southern Brazil, indicates a relatively
