Scientists have added another dinosaur species to the prehistoric catalog, and this one was found in present-day Utah.

Researchers working in Grand Staircase-Escalante National Monument discovered the new species of dinosaur— a large, horned, herbivorous creature that could have been anywhere from 19 to 26 feet long and weighed in at one to two tons. It took them three field seasons to excavate the fossils.

The dinosaur, named Machairoceratops cronusi, is thought to have lived about 77 million years ago. It’s uncommon for a dinosaur of this type to be discovered in this region of the United States, as usually their fossils are found in places like Alaska and Montana.

“Even in a place like western North America, where intense work has been conducted over the past 150 years, we are still finding species new to science," Patrick O’Connor, a coauthor on the study reporting the find, said in a statement.
