Brevirostres is a clade of crocodylians that includes alligatoroids and crocodyloids. Brevirostres are crocodylians with short snouts, and are distinguished from the long, slender-snouted gharials. It is defined phylogenetically as the last common ancestor of Alligator mississippiensis (the American alligator) and Crocodylus niloticus (the Nile crocodile) and all of its descendants. Below is a cladogram showing the phylogenetic relations of Brevirostres from Brochu (1997):
