The name "Saurischia" means "lizard-hipped" and was chosen because of similarity of the animals' hip bones and pelvic joint to that of lizards (although, ironically, birds actually evolved from Saurischians, and not Ornithischia ("bird-hipped") dinosaurs). It should be noted that some groups of Saurischians (the Dromaeosaurids and Therizinosauroids) did later independently evolve a bird-like pubis arrangement
Saurischian dinosaurs included herbivores (plant-eaters), carnivores (meat-eaters) and omnivores, in constrast to the Ornithischia, who were all herbivores (plant-eaters).
The Saurischian order has itself been divided into a number of subgroups. These include:
Saurischian dinosaurs first appeared about 230 million years ago, and survived until the end of the Cretaceous period, about 65 million years ago
