Dinosaurs belong within Archosauria, a wide group of extinct and extant reptiles that also includes modern crocodilians as well as pterosaurs and various basal groups of Triassic age. This chapter considers the origin of the dinosaurs in terms of phylogeny and the timing of events. It discusses the cladistic analysis of Archosauria, followed by an account of the evolutionary events that led to the radiation of the dinosaurs.

Keywords:   dinosaurs, Archosauria, crocodilians, pterosaurs, phylogeny, cladistic analysis
