	Headless dinosaurs \| Science Buzz
		Thecodonts were also ancestral to pterosaurs (flying reptiles).
		There are many fossil thecodonts known, several of which are probably close to the true ancestors of both crocodiles and dinosaurs.
		But it is unlikely that we'd ever be able to say which exact species of thecodont gave rise to which exact species of early dinosaur or crocodile.

		The primitive dinosaurs of the Triassic were neither as abundant nor as varied as they would become in Jurassic and Cretaceous times.
		The dinosaurs are a large group of reptiles belonging to the Archosauria ("ruling reptiles"), which also includes the pterosaurs, or "winged lizards"; crocodilians, the only surviving archosaurs; and the thecodonts, primitive "socket tooth" archosaurs, who were the ancestors of all other archosaurs.
		The thecodonts were still very common, but died out by the end of the Triassic.

	Responses to dinosaur-lung claims
		Croc pubes are only about one tenth as long as the trunk, and when articulated together are broader than they are long!
		I am hard pressed to come up with archosaurs with pubes as short as those of crocodilians, only a few "thecodonts" are similar.
		What are elongate -- to an extreme among archosaurs -- are the pubes of theropods and birds.
