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.

TANYSTROPHEUS (ARCHOSAUROMORPHA, PROLACERTIFORMES) REMAINS FROM THE TRIASSIC OF THE NORTHERN FRIULI (NE ITALY) [PDF]
Rivista Italiana di Paleontologia e Stratigrafia, 2000 The first diagnostic remains of the large prolacertiform Tanystropheus are reported from northeastern Italy. They include a proximal caudal vertebra from the Middle Triassic of Aupa valley (Udine, Friuli) and a cervical vertebra from the Carnian of Fusea

Widespread azendohsaurids (Archosauromorpha, Allokotosauria) from the Late Triassic of western USA and India [PDF]
Papers in Palaeontology, 2021 AbstractArchosauromorph reptiles underwent rapid lineage diversification, increases in morphological and body size disparity, and expansion into new adaptive landscapes. Several of the primary early archosauromorph clades (e.g. rhynchosaurs) are easy to differentiate from others because of their characteristic body types, whereas the more lizard‐like ...

A new archosauriform species from the Panchet Formation of India and the diversification of Proterosuchidae after the end-Permian mass extinction [PDF]
Royal Society Open Science, 2023 Proterosuchidae represents the oldest substantial diversification of Archosauromorpha and plays a key role in understanding the biotic recovery after the end-Permian mass extinction.

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

Functional and ecomorphological evolution of orbit shape in mesozoic archosaurs is driven by body size and diet. [PDF]
Commun Biol, 2022 The orbit is one of several skull openings in the archosauromorph skull. Intuitively, it could be assumed that orbit shape would closely approximate the shape and size of the eyeball resulting in a predominantly circular morphology.
