ScienceDaily (May 28, 2010) — 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, according to a research team led by paleontologists from the Utah Museum of Natural History at the University of Utah.

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.
The study, partially funded by the National Geographic Society, was conducted by Mark Loewen, Scott Sampson, Eric Lund and Mike Getty, paleontologists at the Utah Museum of Natural History. Also involved were Andrew Farke of the Raymond M. Alf Museum in Claremont, Calif.; Martha Aguillón-Martínez, Claudio de Leon and Rubén Rodríguez-de la Rosa from the Museum of the Desert in Saltillo, Mexico; and David Eberth of the Royal Tyrrell Museum of Palaeontology in Alberta, Canada.
The new species is to be announced in the book "New Perspectives on Horned Dinosaurs" to be released next week by Indiana University Press.
