DENVER (AP) — Paleontologists say fossilized bones unearthed at a suburban Denver construction site are those of a large adult triceratops.

Maura O'Neal, a spokeswoman for the Denver Museum of Nature & Science, said Friday the partial skeleton included a limb bone and several ribs of the three-horned dinosaur.

The Denver Post reports the bones were found at a construction site near a retirement community in Highlands Ranch in May in a rock layer that dates back 65 million to 68 million years.

Construction crews are using heavy equipment to dig a deep trench in search for other dinosaur fossils...
