First horned dinosaur from Mexico

n herbivores and carnivores, perhaps representing a previously unknown assemblage of species.

"Rather than focusing only on individual varieties of dinosaurs, we are attempting to reveal what life was like in Mexico 72 million years ago, and understand how the unique ecosystem of Mexico relates to ecosystems to the north at the time," said Loewen.

Few North American dinosaurs from this time period are known outside of the Drumheller region of Alberta. Eberth explained that researchers now have two points of comparison to examine not only different dinosaurs, but also different environments and ecologies.

As might be suspected, paleontologists are excited about the future paleontological potential of this area. "There are definitely more dinosaurs to be discovered in the region," Lund said.

"Dinosaurs from this particular period are important because this is a time that is relatively poorly understood," said Don Brinkman, a researcher at the Royal Tyrrell Museum. He is studying non-dinosaur vertebrates found at the site, including turtles, fish, and lizards. "The locality in Mexico goes a long way to filling in a gap in our knowledge of the record of changes in dinosaur assemblages throughout the Late Cretaceous."

Fact Sheet: Major Points of the Paper - Coahuilaceratops magnacuerna

  • Coahuilaceratops is the first horned dinosaur (ceratopsid) and only the fourth dinosaur species from Mexico to be named and described in scientific literature.

  • Coahuilaceratops represents the southernmost occurrence of a ceratopsid dinosaur.

Relationships

  • Coahuilaceratops is a chasmosaurine ceratopsid, often called a "ceratopsian" or "horned" dinosaur, and was almost certainly an herbivore.

  • Coahuilaceratops is closely related to the famous ceratopsid dinosaurs that appeared in
