Since the definition of Crurotarsi relies on phytosaurs, their placement outside Pseudosuchia ( and thus Archosauria ) means that the clade Crurotarsi includes both pseudosuchians and avemetatarsalians.
22.
The holotype of " Vytshegdosuchus " is also the oldest material currently considered as belonging to Archosauria from Russia, and the only from the Early Triassic.
23.
The choristoderans continued as a minor group until the Miocene, and the Archosauriformes were important factors in early Triassic environments before giving rise to the even more successful Archosauria.
24.
The phylogenetic analysis also indicates that Doswellidae is the closest large monophyletic clade to Archosauria ( only the Chinese archosauriform " Yonghesuchus " nested closer to archosaurs ).

Michael Benton classifies all dinosaurs within the Series Amniota, Class Sauropsida, Subclass Diapsida, Infraclass Archosauromorpha, Division Archosauria, Subdivision Avemetatarsalia, Infradivision Ornithodira, and Superorder Dinosauria.
26.
Recent studies of the evolutionary relationships of early archosauriforms suggest that phytosaurs evolved before the split between crocodile-and bird-line archosaurs and are the sister taxon of Archosauria.
27.
Crocodilians are more closely related to birds and dinosaurs than to most animals classified as reptiles, the three families being included in the group Archosauria ('ruling reptiles').
28.
However, the phylogenetic analysis in that paper resulted in Erpetosuchidae being part of a polytomy with the two main branches of Archosauria, Pseudosuchia and Avemetatarsalia, a distant position from Crocodylomorpha.
29.
However, the presence of vertebrae in the intestines suggests that the exit was wide and that non-avian theropods in this respect were more like present Lepidosauromorpha than extant Archosauria who regurgitate.
30.
A phylogenetic analysis was conducted along with the naming of the genus . " Koilamasuchus " was found to be closely related to Archosauria, a crown group that includes living crocodilians and birds.
