Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
There is no official, canonical list of pterosaur genera, but the most thorough attempts can be found at the Pterosauria section of Mikko Haaramo's Phylogeny Archive, [1] the Genus Index at Mike Hanson's The Pterosauria, [2] supplemented by the Pterosaur Species List, [3] and in the fourth supplement of Donald F. Glut's Dinosaurs: The Encyclopedia series.

Since it was first described, Poposaurus has been variously classified as a dinosaur, a phytosaur, and a "rauisuchian".

However, as a pseudosuchian, it is more closely related to living crocodilians than to dinosaurs. [1]
