Novel data on aetosaur (Archosauria, Pseudosuchia) osteoderm microanatomy and histology: palaeobiological implications

, 2018
One of the most striking features of aetosaurs is the possession of an extensive bony armour composed of dorsal, ventral and appendicular osteoderms.

Taxonomy and phylogeny of the Aetosauria (Archosauria: Pseudosuchia) including a new species from the Upper Triassic of Arizona [PDF]

, 2014
textAetosaurians are a clade of pseudosuchian archosaurs that were globally dispersed during the Late Triassic Epoch. Aetosaurians are characterized by a suite of osteoderms that covered much of the body.

Histología de osteodermos de archosaurioformes no Avemetatarsianos: nuevas inferencias paleobiológicas

, 2019
La presencia de osteodermos es un rasgo compartido por numerosos grupos de Archosauriformes (principalmente dentro de Pseudosuchia y formas no arcosaurianas), cuyo estudio micronanatómico e histológico se ha incrementado en los ultimos años.

Osteohistología de Archosauriformes triásicos sudamericanos (Reptilia: Eucrocopoda): implicancias paleobiológicas

Los arcosauriformes fueron los reptiles dominantes durante el Mesozoico. En los inicios de esta era, en el Período Triásico, los arcosauriformes radiaron en una gran variedad de formas, siendo Archosauria el grupo predominante.

Cranial anatomy of the aetosaur Paratypothorax andressorum Long & Ballew, 1985, from the Upper Triassic of Germany and its bearing on aetosaur phylogeny [PDF]

, 2020
The large aetosaur Paratypothorax andressorum has so far been known only by its osteoderms. Here we describe for the first time the skull of a complete, articulated specimen of this taxon that was found in the type horizon at Murrhardt, southwestern ...

A new archosaur from the Manda beds (Anisian, Middle Triassic) of southern Tanzania and its implications for character state optimizations at Archosauria and Pseudosuchia

, 2014
The presence of early pseudosuchians and avemetatarsalians in Anisian beds of Africa demonstrates that the archosaur radiation was well underway by the beginning of the Middle Triassic.

Cranial anatomy, intraspecific variation, and positional variation within Calyptosuchus wellesi (Pseudosuchia: Aetosauria) based on new specimens from the Upper Triassic Chinle Formation (Adamanian, early middle Norian) of Petrified Forest National Park, Arizona, USA

Journal of Paleontology
Abstract Calyptosuchus wellesi is an aetosaur known from the upper Blue Mesa Member and lowermost Sonsela Member of the Chinle Formation in Arizona, and the Tecovas Formation of the Dockum Group of Texas.
