Construction workers in Thornton were moving dirt for a new police station last month when they uncovered something unusual: a dinosaur. The triceratops skeleton may be the most complete found in the Denver metro area, and it may not be alone. Joe Sertich, curator of dinosaurs at the Denver Museum of Nature and Science, tells Colorado Matters that the Denver metro area sits on land that is good for finding dinosaur bones. "We find them somewhat frequently, but it’s nice to get this attention because it's so close to people. It’s like a window for people to what’s under their feet."
