Denver’s City Park, which was once a dinosaur habitat 67.5 million years ago, has yielded a surprising discovery – a partial-bone fossil of a plant-eating dinosaur.
The find was made during a drilling test to explore geothermal energy potential in January. The core samples reached depths of 1,000 feet into the ground, uncovering the fossilized vertebrae hidden beneath the museum’s parking lot.
Museum scientists have identified the fossil as similar to the Thescelosaurus or Edmontosaurus, a type of dinosaur that roamed during the Late Cretaceous era. The discovery is being hailed as “magical” by Earth sciences research associate Bob Raynolds, who stated that it has never been an opportunity for him to study deep geologic layers with such precision.
The fossil is now on display at the Denver Museum of Nature & Science in its “Discovering Teen Rex” exhibition.
