Construction workers working on the new public safety building in Thornton, Colorado found a rare triceratops skeleton and skull last week.
The find is one of three triceratops skulls found along the Front Range and has likely been laying there for at least 66 million years, Denver Museum of Nature and Science curator of dinosaurs Joe Sertich said in a statement.
So far, a horn and shoulder blade have been discovered. Sertich said that most fossils found in the Denver area are from the Ice Age, roughly 10,000-12,000 years ago, belonging to mammoths, camels and the like. DMNS scientists will stabilize the area, carefully expose the fossil and look for any other bones to be safely extracted.
