Abstract Aetosauria is a clade of obligately quadrupedal, heavily armoured pseudosuchians known from Upper Triassic (late Carnian–Rhaetian) strata on every modern continent except Australia and Antarctica. As many as 22 genera and 26 species ranging from 1 to 6 m in length, and with a body mass ranging from less than 10 to more than 500 kg, are known. Aetosauroides scagliai was recently recovered as the most basal aetosaur, placed outside of Stagonolepididae (the last common ancestor of…

Redescription of Calyptosuchus (Stagonolepis) wellesi (Archosauria: Pseudosuchia: Aetosauria) from the Late Triassic of the Southwestern United States with a discussion of genera in vertebrate paleontology

Mapping of aetosaurian elements from the Placerias Quarry allows for the recognition of associated material providing support for referrals of non-osteoderm material and provides a proposed taxonomic relationship that cannot be unambiguously supported, even by phylogenetic analyses.

Revised phylogenetic analysis of the Aetosauria (Archosauria: Pseudosuchia); assessing the effects of incongruent morphological character sets

A new phylogenetic analysis of the Aetosauria includes more than 40 new characters that focus on better sampling the cranial and endoskeletal regions, and represents the most comprenhensive phylogeny of the clade to date.

A New Aetosaur (Archosauria, Suchia) from the Upper Triassic Pekin Formation, Deep River Basin, North Carolina, U.S.A., and Its Implications for Early Aetosaur Evolution

ABSTRACT Aetosaurs are an extinct clade of quadrupedal, heavily armored archosaurs that had a worldwide distribution during the Late Triassic. Aetosaur fossils from the Upper Triassic Pekin

Anatomical Details of Aetosauria (Archosauria: Pseudosuchia) as Revealed by an Articulated Posterior Skeleton from the Upper Triassic Ischigualasto Formation, San Juan Province, Argentina

Abstract. Aetosaurs are an early-diverging clade of “crocodile-line” archosaurs whose oldest records come from Argentina and Brazil. Articulated skeletons of aetosaurs are rare, but offer insight

Osteology of the Late Triassic aetosaur Scutarx deltatylus (Archosauria: Pseudosuchia)

Aetosaurians are some of the most common fossils collected from the Upper Triassic Chinle Formation of Arizona, especially at the Petrified Forest National Park, and Scutarx deltatylus is potentially an index taxon for the upper part of the Adamanian biozone.

Intraspecific Variation in Aetosauroides scagliai Casamiquela (Archosauria: Aetosauria) from the Upper Triassic of Argentina and Brazil: An Example of Sexual Dimorphism?

It is concluded that the intraspecific variation observed in A. scagliai is compatible with the hypothesis of sexual dimorphism, and the need to explore the sources of intraspokecific variation in aetosaurs is suggested.

A new species of Coahomasuchus (Archosauria, Aetosauria) from the Upper Triassic Pekin Formation, Deep River Basin, North Carolina

Abstract. We describe a new species of the aetosaur Coahomasuchus, C. chathamensis, based on an incomplete, but largely articulated, anterior portion of a skeleton recovered from a quarry in the

The First Braincase of the Basal Aetosaur Aetosauroides scagliai (Archosauria: Pseudosuchia) from the Upper Triassic of Brazil

These features show that the braincase of aetosaurs is suitable for providing further phylogenetic information and may contribute to resolving controversies within Pseudosuchia relationships.

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

These analyses reinforce that recurved and unconstricted maxillary teeth, the shovel-shaped premaxilla and the presence of a tuber on the surangular are plesiomorphic features of Aetosauria.

Cranial Anatomy and Dentition of the Aetosaur Typothorax coccinarum (Archosauria: Pseudosuchia) from the Upper Triassic (Revueltian–Mid Norian) Chinle Formation of Arizona

ABSTRACT Our understanding of Typothorax coccinarum is primarily based on postcranial material, along with a few isolated cranial elements. Here we describe the first complete articulated skull of



A new aetosaur (Reptilia: Archosauria) from the Upper Triassic of Texas and the phylogeny of aetosaurs

Detailed phylogenetic analysis reveals that several North American aetosaur taxa are junior subjective synonyms of previously named taxa.

Aetosaurs (Archosauria:Stagonolepididae) from the Upper Triassic (Revueltian) Snyder Quarry

Both species of aetosaur from the Snyder quarry appear to be anagenetic descendants from more primitive members of the same genus, D. chamaensis from D. haplocerus (Cope) and T. coccinarum from T. antiquum (Hunt).


The distinctive characteristics of the dorsal armor of A. eisenhardtae are a mosaic of features, most of which are found singly or doubly in other aetosaur genera, which indicates a much more complex evolution of aetOSaur armor than previously understood.

ABSTRACT We report two nearly complete, articulated skeletons of the crurotarsan archosaur Typothorax coccinarum from the Upper Triassic Bull Canyon Formation of east-central New Mexico. These are

A new aetosaur genus (Archosauria: Pseudosuchia) from the early Late Triassic of southern Brazil

The recognition of a suite of derived features in Aetobarbakinoides, which is one of the oldest known aetosaurs, is in agreement with an older origin for the group, as it is expected by the extensive ghost lineages at the base of the main pseudosuchian clades.

A New Desmatosuchine Aetosaur (Archosauria: Suchia) from the Upper Triassic Tecovas Formation (Dockum Group) of Texas

The recognition of morphologically distinct specimens such as the holotype and referred material of Sierritasuchus demonstrates that past practices of assigning aetosaur specimens to known taxa based on superficial resemblance has masked diversity in this clade.


Ornithischian dinosaur body fossils are extremely rare in Triassic rocks worldwide, and to date the majority of such fossils consist of isolated teeth. Revueltosaurus is the most common Upper
