A Big-Nosed Horn-Faced Dino

The discovery of a new species of horned dinosaur supports the idea that similar but separate species evolved on the same landmass thanks to a natural barrier.

Nasutoceratops in the swamps of southern LaramidiaRAUL MARTINResearchers have described a new species of dinosaur with a big nose and unusually long horns that lived in western North America roughly 76 million years ago. The 5-meter-long creature, which is detailed in a paper out yesterday (July 18) in the Proceedings of the Royal Society B, has been named Nasutoceratops titusi, which means “big-nose horned-face.”

Paleontologists unearthed multiple specimens, including an almost complete skull, in Utah’s Grand-Escalade National Monument. In the Late Cretaceous period, this area was the southern part a swampy, subtropical island called Laramidia, cut off from the rest of North America by an inland sea.

Nasutoceratops’s distinct headgear distinguishes it from other centrosaurines, a group of horned dinosaurs that includes Centrosaurus and Styracosaurus. The discovery that a previously unknown centrosaurine roamed the southern part of Laramidia provides support for the idea that some sort of barrier caused divergent evolution on the continent, because the new species is distinct from those found in what would have been Laramdia’s northern reaches. It is not clear what barrier separated them, however.

The function of the big nose, and the large empty spaces it contained, is also mystery.
