A rare dinosaur fossil is found.

FOX's Chris Foster reports:

Construction crews building a new public safety facility in Thornton, Colorado found it: The skull and skeleton of a Triceratops:

(Sertich) "We have the horn core and part of the eyes."

Joe Sertich, with the Denver Museum of Nature and Science says the bones have probably been there for 66 million years.

Most fossil finds are more like 10 or 12,000-years-old.

(Sertich) "Dinosaurs get bulldozed all the time around Denver. This is just one of those lucky times that the right person was there and they noticed what was going on."

The bones are still in the ground to be analyzed and carefully extracted.
