Desmatosuchini
Desmatosuchinae is a major subfamily of aetosaurs within the clade Desmatosuchia. It is a stem-based taxon defined as all aetosaurs more closely related to '' Desmatosuchus'' than to '' Stagonolepis,'' ''Aetosaurus'', or '' Paratypothorax''. The clade Desmatosuchinae has often been restricted to a few closely-related aetosaurs with spiny armor, such as ''Desmatosuchus'', '' Longosuchus'', and ''Lucasuchus''. It was later expanded to include a number of '' Stagonolepis''-like aetosaurs with less specialized armor. Under this more expansive usage, the strongly-supported clade encompassing "traditional" desmatosuchines (''sensu stricto'') was given a new name, Desmatosuchini. Synapomorphies that diagnose this clade can be found in the osteoderms. These include tongue-and-groove articulations for lateral plates present in dorsal presacral paramedian plates and large spikes on the lateral cervical, dorsal, and caudal plates.

Aetosaur
Aetosaurs () are heavily armored reptiles belonging to the extinct order (biology), order Aetosauria (; from Ancient Greek, Greek, (aetos, "eagle") and (, "lizard")). They were medium- to large-sized Omnivore, omnivorous or Herbivore, herbivorous Pseudosuchia, pseudosuchians, part of the branch of archosaurs more closely related to crocodilians than to birds and other dinosaurs. All known aetosaurs are restricted to the Late Triassic, and in some strata from this time they are among the most abundant fossil vertebrates. They have small heads, upturned snouts, erect limbs, and a body ornamented with four rows of plate-like Osteoderm, osteoderms (bony scutes). Aetosaur fossil remains are known from Europe, North America, North and South America, parts of Africa, and India. Since their armoured plates are often preserved and are abundant in certain localities, aetosaurs serve as important Late Triassic tetrapod index fossils. Many aetosaurs had wide geographic ranges, but their stra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gorgetosuchus
''Gorgetosuchus'' is an extinct genus of aetosaur from the Late Triassic of the North Carolina, represented by the type species ''Gorgetosuchus pekinensis''. It is mainly known from osteoderms, including the front half of an articulated carapace. ''Gorgotesuchus'' is typically considered a basal desmatosuchin, though alternative interpretations exist. Discovery ''G. pekinensis'' was named and described by Heckert ''et al.'' (2015) on the basis of ten rows of bony plates called osteoderms, representing the front part of an armored carapace that would have covered the back of the animal. These plates were found embedded in sandstone and conglomerate boulders near a brick quarry in Chatham County, North Carolina, which likely originated from the Late Triassic Pekin Formation. (The Pekin Formation consists of interbedded red mudstones, siltstones, sandstones and conglomerates; it was the fine-grained mudstones and siltstones that the mining operation was targeting for brick-makin ...

Stagonolepis
''Stagonolepis'' is an extinct genus of stagonolepidid aetosaur known from the Late Triassic (Carnian stage) Hassberge Formation of Germany, the Drawno Beds of Poland, and the Lossiemouth Sandstone of Scotland. Supposed fossils from North and South America have been placed into their own genera, '' Calyptosuchus'' and '' Aetosauroides'', respectively. Description ''Stagonolepis robertsoni'' was about long. It was a quadrupedal animal covered in thick armoured scales that ran down the length of its body. A slow-moving browser, it would have used this heavy body armour to repel attacks from contemporary thecodont carnivores. ''Stagonolepis'' had a very small head for its size; it was only , accounting for less than 10% of the total body length. It had no teeth in the front of its jaws, but instead had a beak-like tip that arched upwards. This would have allowed it to uproot plants in a similar manner to a modern pig. The peg-like teeth at the back of its mouth would have b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
