Desmatosuchus was a large quadrupedal reptile measuring 4.5 m (15 ft) to over 5 m (16 ft) long and weighing about 280–300 kg (620–660 lb). [2][3][4][5] Its vertebral column had amphicoelous centra and 3 sacral vertebrae. This archosaur's most distinguishing anatomical characteristics were its scapulae which possessed large acromion ...
Gorgetosuchus? Desmatosuchinae is a major subfamily of aetosaurs within the clade Desmatosuchia. [ 1] It is a stem-based taxon defined as all aetosaurs more closely related to Desmatosuchus than to Stagonolepis,[ 2] Aetosaurus, or Paratypothorax. [ 1] The clade Desmatosuchinae has often been restricted to a few closely related aetosaurs with ...
Postosuchus, meaning "Crocodile from Post ", is an extinct genus of rauisuchid reptiles comprising two species, P. kirkpatricki and P. alisonae, that lived in what is now North America during the Late Triassic. Postosuchus is a member of the clade Pseudosuchia, the lineage of archosaurs that includes modern crocodilians (the other main group of ...
Desmatosuchus was likely one of the largest known aetosaurs, at 4–6 m (13–20 ft) in length and 280 kg (620 lb) in weight. [12] [3] [13] Aetosaurs which do not fit into these two categories, such as Stagonolepis and Neoaetosauroides, generally had narrow forms, slender limbs, and a restriction in the carapace above the hip.

Binomial name. †Rioarribasuchus chamaensis. (Zeigler, Heckert & Lucas, 2003) Synonyms. Desmatosuchus chamaensis Zeigler, Heckert & Lucas, 2003. Rioarribasuchus is a genus of aetosaur. Fossils have been found from the Chinle Formation in Arizona and New Mexico that date back to the upper Late Carnian stage of the Late Triassic .
Pinus, the pines, is a genus of approximately 111 extant tree and shrub species. The genus is currently split into two subgenera: subgenus Pinus (hard pines), and subgenus Strobus (soft pines). Each of the subgenera have been further divided into sections based on chloroplast DNA sequencing [1] and whole plastid genomic analysis. [2]
The classification of Acaenasuchus as an independent taxon has been the topic of controversy due to its similarities to Desmatosuchus. Upon review by Andrew B. Heckert and Spencer G. Lucas, the characters that Long and Murry claim to distinguish between the two species may not represent novel scute features but rather ontogenetic variation. [6]
A study estimating moment arms for major pelvic limb muscles in extant and fossil archosaurs, aiming to investigate the idea that bird-line archosaurs switched from hip-based to knee-based locomotion between Archosauria (especially Neotheropoda) and Aves, is published by Allen, Kilbourne & Hutchinson (2021).
