The first, Pseudosuchia, was established as a stem-based clade in 1985. [5] It includes crocodiles and all archosaurs more closely related to crocodiles than to birds. The second, Crocodylotarsi, was named in 1988, possibly as a replacement for Pseudosuchia. [ 6 ]
The name Pseudosuchia was originally given to a group of superficially crocodile-like prehistoric reptiles from the Triassic period, but fell out of use in the late 20th century, especially after the name Crurotarsi was established in 1990 to label the clade (evolutionary grouping) of archosaurs encompassing most reptiles previously identified as pseudosuchians.
Suchia is a clade of archosaurs containing the majority of pseudosuchians (crocodilians and their extinct relatives). It was defined as the least inclusive clade containing Aetosaurus ferratus, Rauisuchus tiradentes, Prestosuchus chiniquensis, and Crocodylus niloticus (the living Nile crocodile) by Nesbitt (2011). [1]
Rauisuchians are a category of archosaurs within a larger group called Pseudosuchia, which encompasses all archosaurs more closely related to crocodilians than to birds and other dinosaurs. First named in the 1940s, Rauisuchia was a name exclusive to Triassic archosaurs which were generally large (often 4 to 6 metres (13 to 20 ft)), carnivorous ...
Poposauroidea was a diverse group of pseudosuchians, containing genera with many different ecological adaptations. Some (Poposaurus and shuvosaurids) were short-armed bipeds, while others (ctenosauriscids and Lotosaurus) were robust quadrupeds with elongated neural spines, creating a 'sail' like that of certain "pelycosaurs" (like Dimetrodon) and spinosaurids.

Aetosaurus is an extinct genus of pseudosuchian reptile belonging to the order Aetosauria.It is generally considered to be the most primitive aetosaur. [1] Three species are currently recognized: A. ferratus, the type species from Germany and Italy; [2] A. crassicauda from Germany; [3] and A. arcuatus from eastern North America. [4]
Prestosuchus (meaning "Prestes crocodile") is an extinct genus of pseudosuchian in the group Loricata, which also includes Saurosuchus and Postosuchus.It has historically been referred to as a "rauisuchian", and was the defining member of the family Prestosuchidae, though the validity of both of these groups is questionable: Rauisuchia is now considered paraphyletic and Prestosuchidae is ...
