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.

The Denver Museum of Nature and Science made a surprise discovery during a project on the museum's parking lot: a 70 million-year-old dinosaur fossil.
