Ornithischians

An Ornithischian dinosaur had a hip like a bird and they were all plant eaters. The Ornithischians all showed an improvement on their hind limbs, but on their forelimbs they did not get much improvement. One of the earliest suborder groups of the Ornithischians were the Ornithopods, but there were also the Thyreophoras, the Ankylosaurias and the Ceratopias. Because of the hip, which looked like a bird, some scientists believe that this group of dinosaurs evolved into some of our present birds.
