Coahuilaceratops , First Horned Dinosaur From Mexico A new species of horned dinosaur unearthed in Mexico has larger horns that any other species - up to 4 feet long - and has given scientists fresh insights into the ancient history of western North America. The 72-million-year-old rhino-sized creature - Coahuilaceratops magnacuerna - was a four- to five-ton plant-eater belonging to a group called horned dinosaurs, or ceratopsids. The nameCoahuilaceratops magnacuerna (Koh-WHE-lah-SARA-tops mag-NAH-KWER-na), refers to the Mexican state of Coahuila where it was found, and to the Greek word “ceratops” meaning “horned face.” The second part of the name, magnacuerna, is a combination of Latin and Spanish meaning “great horn,” in reference to the huge horns above the eyes of this dinosaur. Loewen explained that Coahuilaceratops represents the first occurrence of an identifiable species of horned dinosaur in southern Mexico. “The horned dinosaurs are an extraordinary example of vertebrate evolution,” he said. They evolved and diversified on Laramidia along a thin strip of land that stretched from Alaska to Mexico. “Finding this horned dinosaur so far south in Mexico offers us a different picture of what the ancestors ofTriceratops were like.”
