Einiosaurus was a medium-sized ceratopsian dinosaur that lived in North America approximately 74.5 million years ago and was first discovered in the 1980s in Montana, United States. The name means \"Buffalo Lizard,\" which stands for an American Indian term and a Greek term. Ennio means \"bison or buffalo\" and \"Saurus\" means lizard. The remains were discovered by Jack Horner in 1985 and excavated between 1985 and 1989 by field crews from the Museum of the Rockies. There were at least 15 bones of various ages, belonging to old and young individuals.<\/p>\n\n\n\n

It was a horned dinosaur or known as a ceratopsian. These animals were \"Cretaceous buffaloes\" because they lived in large herds. Unlike any other dinosaur, it had an impressive curved horn that was used as a defensive weapon or just for show. According to scientists, the ornament could be colorful for mating or helped individuals recognize others of the same species. However, the frill was unreliable and contained two large holes, the reason why it had not been an effective shield. But thanks to its spines that were used as protection to ward off predators. <\/p>\n\n\n\n

The Einiosaur's forward-curved nose horn made it unique among the others. It had a horny beak and walked on four short, stout legs. It lived in a warm, semi-arid environment and stayed in a shallow lake bed.<\/p>\n\n\n\n

Einiosaurus grew to 4.5 in length and weighed 1,300 kg.<\/p>\n\n\n\n
