Paleontologists from the Denver Museum of Nature and Science started digging up the bones at the site where a police substation is under construction.

A spokesperson for the Denver Museum of Nature and Science said that the fossil belongs to that of a Triceratops classified as a “sub-adult” in late teens or early 20s.
