Anyone care to fix the Tapejara entry? Tupandactylus (the creature with the tall crest) has been recognized as distinct since 2007.

Did some proofreading. Made some changes. Recent evidence suggests Mosasaurs are more closely related to monitor lizards than snakes, so I added that. Added that crocodilians are members of the clades Crurotarsi and Pseudosuchia. Note: they're essentially the same except Crurotarsi includes the phytosaurs whereas Pseudosuchia doesn't.

More specifically, Crurotarsi includes phytosaurs by definition while Pseudosuchia does not. If phytosaurs are closer to crocs than to birds, they do fall under Pseudosuchia. However, if phytosaurs are outside of Archosauria altogether (which may well be the case) as in Nesbitt's extensive phylogeny, they do not fall under Pseudosuchia and Crurotarsi includes all archosaurs, including birds (as Crurotarsi is defined as anything descended from the last common ancestor of phytosaurs and crocs).
