Review of osteoderm function and future research directions
Osteoderms are bone plates in the skin that occur in virtually all major tetrapod clades. Much has been speculated about their function, but many questions remain unanswered. This review provides an overview of the current state of knowledge and future research directions in this field.

Pelvic girdle morphology in Stagonolepis, with remarks on aetosaur systematics
In recent years, the Upper Triassic deposits at Krasiejów (south-west Poland) have yielded several tetrapod taxa, both aquatic and terrestrial. Stagonolepis olenkae is one of the terrestrial vertebrates recovered there; a quadrupedal, armoured aetosaur ...

The Los Colorados Formation (Upper Triassic, Norian) is characterised by its extensive tetrapod fossil record, especially of archosaurs. As part of this record, Aetosauria (Late Triassic pseudosuchians characterised by the presence of dorsal, ventral and appendicular osteoderms) is represented only by Neoaetosauroides engaeus.

Aetosaurs were a group of armoured pseudosuchians, recorded in most of the Upper Triassic continental deposits worldwide. Several osteohistological contributions of aetosaurs focused on their osteoderms, but rarely on appendicular bones. Here, we analyse

Reinterpretation of the holotype of Malerisaurus langstoni, a diapsid reptile from the Upper Triassic Chinle Group of West Texas [PDF]
The holotype of Malerisaurus langstoni from the Late Triassic (Otischalkian) Trilophosaurus quarry 2 of West Texas is a chimera. The holotype represents at least 6-7 individuals of four reptilian groups: Trilophosauridae, Rhynchosauridae, Parasuchidae ...

The phylogenetic relationships of Pseudosuchia, the crocodile-line of Archosauria, are still poorly resolved, in part, due to the lack of crucial braincase information for several key taxa.

X-Ray Computed Tomographic Reconstruction And Bone Histology Of The Aetosaur Coahomasuchus Chathamensis (Archosauria: Stagonolepididae) From The Upper Triassic Pekin Formation, Deep River Basin, North Carolina And A Re-Analysis Of Its Phylogenetic Relationships [PDF]
Aetosauria is a clade of armored, quadrupedal archosaurian omnivores to herbivores known from Upper Triassic units globally. However, there remains debate about their: intra-clade relationships, internal skeletal structure, and patterns of growth.

Osteoderms of juveniles of Stagonolepis (Archosauria: Aetosauria) from the lower Chinle Group, east-central Arizona [PDF]
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.

Bone Histology of Phytosaur, Aetosaur, and Other Archosauriform Osteoderms (Eureptilia, Archosauromorpha) [PDF]
As in other archosauriforms, phytosaurs and aetosaurs are characterized by the presence of well-developed osteoderms. Here we provide a comparative study on the microstructure of phytosaur (five taxa) and aetosaur (thirteen taxa) osteoderms. For outgroup
