Long-horned Dinosaur Fossil in Mexico

SALT LAKE CITY, May 28 (UPI) — A rhino-sized dinosaur that roamed Mexico 72 million years ago grew horns as long as 4 feet, researchers from the University of Utah said.

Coahuilaceratops magnacuerna, a plant eater, had the longest horns of any species of its time, said paleontologists from the university’s Museum of Natural History.


The fossilized remains, found in the Mexican state of Coahuila, gives scientists new insight into the ancient history of western North America.

“We know very little about the dinosaurs of Mexico, and this find increases immeasurably our knowledge of the dinosaurs living in Mexico during the Late Cretaceous” period, paleontologist Mark Loewen said in a release Friday.

The Coahuila region 72 million years ago was a humid estuary with lush vegetation, much like the modern Gulf Coast of the southeastern United States. Dinosaur bones from the area were found covered with fossilized snails and marine clams, indicating the dinosaurs lived adjacent to the seashore, Loewen and his team said.
