what kind of eater is the saurischia
Move deeper into the systematics of dinosaur groups by selecting one of the boxes containing a picture. With the discovery of many new species since the 1840s, the Dinosauria now contains two major groups of dinosaurs: the Ornithischia, or bird-hipped dinosaurs, and the Saurischia, or lizard-hipped dinosaurs. The division between the two groups was made by H.G. Seeley in 1888. The etymology behind the two names (bird-hipped vs. lizard-hipped) is not very accurate, since some saurischians had bird-like hips, and ornithischians' hips were somewhat birdlike due to convergent evolution, not due to direct ancestry.
