The higher-level phylogeny of Archosauria (Tetrapoda: Diapsida)
- S. Brusatte, M. Benton, J. Desojo, M. Langer
- Environmental Science
- 12 March 2010
This analysis produces a well-resolved phylogeny, which recovers mostly traditional relationships within Avemetatarsalia, places Phytosauria as a basal crurotarsan clade, finds a close relationship between Aetosaurian and Crocodylomorpha, and recovers a monophyletic Rauisuchia comprised of two major subclades.

A Middle–Late Triassic tetrapod assemblage from South America reveals a series of faunal turnovers prior to the rise of dinosaurs in the region.
An unusual new archosauriform from the Middle–Late Triassic of southern Brazil and the monophyly of Doswelliidae

The phylogenetic analysis indicates that Doswellidae is the closest large monophyletic entity to Archosauria, which achieved a wide palaeolatitudinal distribution during the late Middle and Late Triassic time span.
Aetosauria: a clade of armoured pseudosuchians from the Upper Triassic continental beds

- 13 June 2013
Aetosauria is a clade of obligately quadrupedal, heavily armoured pseudosuchians known from Upper Triassic strata on every modern continent except Australia and Antarctica, and there is increasing evidence that at least some aetosaurs relied on invertebrates and/or small vertebrates as a food source.
The Evolution of Extreme Hypercarnivory in Metriorhynchidae (Mesoeucrocodylia: Thalattosuchia) Based on Evidence from Microscopic Denticle Morphology

A cladistic analysis shows that ziphodont dentition may have evolved independently in Dakosaurus and Geosaurus, or been acquired earlier by their common ancestor and secondarily lost in Torvoneustes and related taxa.
CRANIAL MORPHOLOGY OF THE LATE TRIASSIC SOUTH AMERICAN ARCHOSAUR NEOAETOSAUROIDES ENGAEUS: EVIDENCE FOR AETOSAURIAN DIVERSITY
The conical shape of the teeth of N. engaeus differs from the slightly compressed teeth of Desmatosuchus, Stagonolepis and Typothorax, and the distinctly recurved teeth of Aetosaurus and Aetosauroides, which suggests a variety of food-item preferences among aetosaurs.
The Cranial Osteology and Feeding Ecology of the Metriorhynchid Crocodylomorph Genera Dakosaurus and Plesiosuchus from the Late Jurassic of Europe

It is hypothesized that trophic specialisation enabled these two large-bodied species to coexist in the same ecosystem and is supported by Plesiosuchus manselii having a very large optimum gape, while Dakosaurus maximus possesses craniomandibular characteristics observed in extant suction-feeding odontocetes.
Osteology and cranial musculature of Caiman latirostris (crocodylia: Alligatoridae)
- Paula Bona, J. Desojo
- BiologyJournal of morphology
- 1 July 2011
The skull of C. latirostris differs from that of other caimans and possesses several characters that are potential diagnostic features of this species and should be analyzed within the phylogenetic context of the Caimaninae to evaluate its evolutionary implications for the history of the group.
Cranial anatomy of the aetosaur Paratypothorax andressorum Long & Ballew, 1985, from the Upper Triassic of Germany and its bearing on aetosaur phylogeny
The resemblance of Paratypothorax and Aetosaurs in many cranial features, their close relationship as suggested by the present analysis, and the immature state of all available Aetosaurus specimens suggest two new alternative hypotheses.
The Late Triassic Ischigualasto Formation at Cerro Las Lajas (La Rioja, Argentina): fossil tetrapods, high-resolution chronostratigraphy, and faunal correlations

- Geography, Environmental ScienceScientific Reports
- 29 July 2020
The temporally calibrated Ischigualasto biostratigraphy suggests the persistence of rhynchosaur-dominated faunas into the earliest Norian, and partially fills the ghost lineage between younger ornithischian records and the oldest known saurischians at ca.
