Protoceratops Mourii

Protoceratops Mourii is an extinct ceratopsid that live in what is now Europe, Pakistan, Mongolia, China, and Siberia during the early Cenozoic era from 63 million years ago to 45 million years ago. They are most likely herbivorous based on a modern Korean goatbird and their extinct relatives of the Mesozoic era. They grew to about the size of a pig and were probably about as docile as modern sheep. They were very common during the earliest part of the Cenozoic era probably due to lack of competition and had abundance of food, so they were the most common of the early Cenozoic land animals, about as common as Lystrosaurus during the early Triassic (which also became just as common), as both Lystrosaurus and Protoceratops survived and find any plants available. The Protoceratops, however, finally became extinct in about 45 million years ago for some odd reason, but it may have been due to competition from newer mammal herbivores and/or from being overhunted by newer mammal predators.
