Officials stumbled upon a 67-million-year-old dinosaur bone beneath the Denver Museum of Nature and Science during a drilling project, the DMNS announced on Wednesday.

The Denver Museum of Nature and Science is filled with exhibits of dinosaur skeletons. And in the scientific equivalent of tossing couch cushions, its scientists discovered a dinosaur fossil deep — really deep — below the surface of one of its own parking lots, the museum announced this week.

This dino-mite find, which Hagadorn described as "quite the cherry" on top of the project's intended mission, was discovered 763 feet below the surface and was identified as the "deepest and oldest dinosaur fossil ever found within the city's limits," the museum said in a press release.
