Many kinds of horned dinosaurs roamed what is now western North America 85 to 66 million years ago. The most famous - and also the largest - was Triceratops, named for the three prominent horns on its face.

Now, a new species of horned dinosaur has been identified. Dr. Jordan Mallon, a paleontologist from The Canadian Museum of Nature in Ottawa, identified the new species from 76-million-year-old fossils found in Montana's Judith River geological formation.

Nicknamed "Judith," this dinosaur had horns that stuck out sideways above the eyes, as well as numerous bony spikes on a frill at the back of the skull. "Judith" provides more evidence of the diversity of horned dinosaurs.
