Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae)

Journal of Anatomy, Volume 248, Issue 6, Page 1026-1063, June 2026.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...

Braincase anatomy and palaeoneurology of Venetoraptor gassenae, a lagerpetid pterosauromorph from the Late Triassic of southern Brazil

Palaeontology, Volume 69, Issue 2, 2026.
Abstract There is a growing consensus that pterosaurs and the flightless Lagerpetidae are closely related. This relationship is supported by apomorphies throughout the skeleton, including endocranial character states such as a well‐developed floccular fossa and a tall anterior semicircular canal. Our knowledge of lagerpetid anatomy has been improved by

Osteology of the first skull of Aetosauroides scagliai Casamiquela 1960 (Archosauria: Aetosauria) from the Upper Triassic of southern Brazil (Hyperodapedon Assemblage Zone) and its phylogenetic importance. [PDF]

PLoS One, 2018
Aetosauria, which includes 30 species, is a diverse group of armored pseudosuchian archosaurs restricted to Upper Triassic beds. Three species occur in Brazil, and one of these, Aetosauroides scagliai Casamiquela, 1960, also occurs in Argentina.

Mosaic evolution in an asymmetrically feathered troodontid dinosaur with transitional features [PDF]

, 2017
Asymmetrical feathers have been associated with flight capability but are also found in species that do not fly, and their appearance was a major event in feather evolution.

The phylogeny of basal archosaurs [PDF]

, 1994
Archosaur systematics has received much attention from the mid 1970s and several influential works on this topic have emerged. As discrepancy exists among proposed phylogenies, some of the most important of the papers in question are assessed here ...

A new species of the Late Triassic aetosaur Desmatosuchus (Archosauria: Pseudosuchia)

Comptes Rendus Palevol, 2005
Reanalysis of known armor of the stagonolepidid (aetosaur) Desmatosuchus has shown distinct differences in the lateral armor among individuals known from Carnian and Norian age rocks in the southwestern United States. Combined with previously reported cranial differences it is apparent that Norian specimens of Desmatosuchus represent a species distinct

Endocranial anatomy and phylogenetic position of the crocodylian Eosuchus lerichei from the late Paleocene of northwestern Europe and potential adaptations for transoceanic dispersal in gavialoids

The Anatomical Record, Volume 308, Issue 2, Page 636-670, February 2025.
Abstract Eosuchus lerichei is a gavialoid crocodylian from late Paleocene marine deposits of northwestern Europe, known from a skull and lower jaws, as well as postcrania. Its sister taxon relationship with the approximately contemporaneous species Eosuchus minor from the east coast of the USA has been explained through transoceanic dispersal ...
