Described in a study published in the current issue of Proceedings of the Royal Society B, Nasutoceratops titusi, or "big-nose, horn-face," is named for its most significant features: the two enormous horns protruding from its head and its prodigious snout. It the first from the group of short-frilled, horned dinosaurs to have been found in the American south, revising previous theories that those dinosaurs lived only in the north.
“It’s not every day you find a whole new group of dinosaurs,” says Scott Sampson, a paleontologist at The Denver Museum of Nature & Sciences and the lead author on the study, in a phone interview. “And this is a linchpin to demonstrate that there were distinct dinosaur communities in the north and south.”
