Leptoceratops
Mary Evans Picture Library/Deagostini Editore
Leptoceratops was a herbivore with a long, slender body (about 2 metres), short forelimbs, and may have spent most of its time walking or standing on its hind legs. It is considered to be one of the more primitive ceratopsians, without large frills and horns. It lived about 68-65 million years ago in North America.
