US EditionDenver Museum of Nature & Science Finds Nearly 70-Million-Year-Old Dinosaur Fossil
DENVER COUNTY, COLORADO, JUL 9 – Researchers uncovered a Late Cretaceous plant-eater vertebra 763 feet underground, offering rare insight into Denver's ancient ecosystem, museum officials said.
- In January 2025, during geothermal drilling nearly 763 feet below the parking area of a natural history museum in Denver’s City Park, researchers uncovered a dinosaur fossil estimated to be around 67.5 million years old.
- The fossil find resulted from a scientific coring initiative driven by the museum's exploration of geothermal energy to replace natural gas heating and cooling systems.
- Museum researchers identified the fossil as a vertebral centrum from a plant-eating dinosaur similar to Thescelosaurus or Edmontosaurus, revealing a rare view of Denver's Late Cretaceous ecosystem.
- Patrick O'Connor described the discovery as unlike any other dinosaur find he has experienced, while Bob Raynolds called the discovery truly extraordinary.
- This discovery, the deepest and oldest such fossil within Denver city limits, offers scientific value and public educational potential while enriching understanding of urban paleontology.
