On the homology of crocodylian post‐dentary bones and their macroevolution throughout Pseudosuchia

The Anatomical Record, 2022
AbstractThe lower jaw of early tetrapods is composed of several intramembranous ossifications. However, a tendency toward the independent reduction of the number of bones has been observed in the mandible of mammals, lepidosaurs, turtles, crocodiles, and birds.

Anatomy, taxonomy and phylogenetic relationships of Prestosuchus chiniquensis (Archosauria: Pseudosuchia) from the original collection of von Huene, Middle-Late Triassic of southern Brazil [PDF]

Palaeontologia Electronica, 2020
A review of the type and referred material of von Huene shows that Prestosuchus is a valid taxon represented by, at least, three different species: the lectotype and para-lectotype of Prestosuchus chiniquensis, an unnamed species from Brazil (UFRGS-PV ...

The first braincase of the basal aetosaur Aetosauroides scagliai (Archosauria: Pseudosuchia) from the Upper Triassic of Brazil

Journal of Vertebrate Paleontology, 2021
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. Recently, erpetosuchids and ornithosuchids have been recovered as close relatives to Aetosauria, sharing several braincase features. Here we provide the description

Osteology of the Late Triassic Bipedal Archosaur Poposaurus gracilis (Archosauria: Pseudosuchia) from Western North America

The Anatomical Record, 2019
ABSTRACTPoposaurus gracilis is a bipedal pseudosuchian archosaur that has been poorly understood since the discovery of the holotype fragmentary partial postcranial skeleton in 1915. Poposaurus. gracilis is a member of Poposauroidea, an unusually morphologically divergent clade of pseudosuchians containing taxa that are bipedal, quadrupedal, toothed ...

Axial skeleton ontogeny in the Parasuchia (Archosauria: Pseudosuchia) and its implications for ontogenetic determination in archosaurs

Journal of Vertebrate Paleontology, 2007
Abstract The sequence of neurocentral suture closure is one criterion for the determination of ontogenetic stage in extant crocodylians. This pattern is frequently used to assess ontogeny for a variety of fossil archosaurs that may or may not follow the same sequence and timing of suture closure.
