ornithischian dinosaurs: One of the two major groups of dinosaurs, the other being the saurischians.
Dinosaurs are divided into two main orders: saurischians, which have forward-pointing pubic bones, and ornithischians, which have backward-pointing pubic bones.
For example, among the 12 major vertebrate clades, extinctions were concentrated in seven of them; sharks, ornithischians, pterosaurus, saurischians, non-trilasghemic mammals, lizards, and marsupials accounted for about 75% of the extinctions (4).
