Monoclonius, A dinosaur that is often confused with another species called Centrosaurus because they were very much alike. Actually so much identical that many scientists think that they are the same species but only different ages or sexes.

Monoclonius have been found in the regions of Canada, Mongolia , and Montana . The first fossil was found in 1876. It was a full body and head, but without feet. Mr. Edward Cope has made the discovery and then described the dinosaur. Not long after, in 1889 he then discovered the Triceratops..

The Dinosaur had a large head, a spike on its nose like a rhinoceros, and heavily armored body, and was 9feet tall, and 20 feet long at an adult full grown age. It was a herbivore as well like many of the other dinosaurs in its group (Ceratopsidae).
