What is "suchia"

Suchia is a clade of archosaurs that includes all pseudosuchians except for the ornithosuchids. It includes crocodilians and their extinct relatives. It was defined as the least inclusive clade containing Aetosaurus ferratus, Rauisuchus tiradentes, Prestosuchus chiniquensis, Gracilisuchus stipanicicorum, and Crocodylus niloticus (the living Nile crocodile) by Nesbitt (2011).
