Massively simplified cladogram of crocodilians and their relatives, with numerous lineages not shown. The affinities between "rauisuchians", aetosaurs and crocodylomorphs are shown here as being unresolved, but some studies find aetosaurs to be closer to crocodylomorphs than are other croc-group archosaurs. Other studies find at least some "rauisuchians" to be closer to crocodylomorphs than are other croc-group archosaurs. Within Crocodylomorpha, some studies find thalattosuchians to be further away from Crocodylia than is Notosuchia. Originally used in <a href=W"[link]
