The 20ft long Xenoceratops foremostensis, is the oldest known large-bodied horned dinosaur from the region.

Dr. Michael Ryan, curator of vertebrate paleontology at The Cleveland Museum of Natural History, said:

“Starting 80 million years ago, the large-bodied horned dinosaurs in North America underwent an evolutionary explosion. Xenoceratops shows us that even the geologically oldest ceratopsids had massive spikes on their head shields and that their cranial ornamentation would only become more elaborate as new species evolved.”

Kieran Shepherd, curator of paleobiology for the Canadian Museum of Nature, which holds the specimen, said:



“This discovery of a previously unknown species also drives home the importance of having access to scientific collections. The collections are an untapped source of new material for study, and offer the potential for many new discoveries.”
