Lithodendron: The Science and History Journal of Petrified Forest National Park
Recent collecting of fossil vertebrates in the Chinle Formation at Petrified Forest National Park (PEFO) and reinvestigation of historic collections resulted in the recognition of a new aetosaurian taxon, Kryphioparma caerula. Although distinctive, K.

A new species of Desmatosuchus (Archosauria: Aetosauria) from the Upper Triassic of the Chama basin, north-central New Mexico. [PDF]
, 2002 We describe a new species of the aetosaur Desmatosuchus, D. chamaensis, from the Upper Triassic Snyder quarry, Petrified Forest Formation of the Chinle Group, Chama basin of north-central New Mexico. D. chamaensis is also present in the Bull Canyon Formation of east-central New Mexico. D. chamaensis is distinguished from the type and only other species

Revision of Redondasuchus (Archosauria: Aetosauria) from the Upper Triassic Redonda Formation, New Mexico, with description of a new species [PDF]
, 2006 We describe a new species of aetosaur, Redondasuchus rineharti, based on isolated scutes and an incomplete femur from a single locality in the Upper Triassic Redonda Formation of east-central New Mexico. R. rineharti is distinguished from R. reseri, the only other species of Redondasuchus, by its scute morphology, specifically by its large size ...

AbstractMaximum individual body size in pseudosuchian archosaurs is not well constrained in the fossil record, but it may be influenced by a variety of factors including basal metabolic rate, evolutionary relationships, and environmental conditions.

ABSTRACTAetosaurs comprise a clade of quadrupedal, armored, omnivores to herbivores that lived across much of the supercontinent of Pangea during the Late Triassic. Their relative abundance in many units, and the rarity of other Triassic herbivores, points to them as key components of Late Triassic ecosystems.

Journal of Systematic Palaeontology, 2007
Synopsis Study of aetosaurian archosaur material demonstrates that the dermal armour of Desmatosuchus chamaensis shares almost no characters with that of Desmatosuchus haplocerus. Instead, the ornamentation and overall morphology of the lateral and paramedian armour of ’D.’ chamaensis most closely resembles that of typothoracisine aetosaurs such as ...

We describe for the first time small «25 mm) dorsal paramedian, lateral, and appendicular /ventral scutes (osteoderms) of aetosaurs from the Blue Hills in Apache County, east-central Arizona. These diminutive scutes, collected by c.L. Camp in the 1920s, preserve diagnostic features of the common Adamanian aetosaur Stagonolepis. Stagonolepis wellesi was

Intraspecific Variation inAetosauroides scagliaiCasamiquela (Archosauria: Aetosauria) from the Upper Triassic of Argentina and Brazil: An Example of Sexual Dimorphism? [PDF]
Ameghiniana, 2015 Aetosaurs are a group of quadrupedal, armoured pseudosuchian archosaurs from the Upper Triassic. They are characterized by dorsal and ventral carapaces, and appendicular osteoderms, all of them ornamented.
