Dinosaur footprint discovered at NASA flight center

GREENBELT, Md. (CNN/NASA) - A dinosaur tracker made a gargantuan find in the middle of a NASA campus in Greenbelt, Md.

As it turns out, Ray Stanford discovered the back footprint of a large dinosaur known as the Nodosaur at NASA's Goddard Space Flight Center.

"And I love the paradox," Stanford says. "Here is space scientists, and they walk along here, and they're walking exactly where this big, bungling, heavy, armored dinosaur walked, maybe 110- to 112 million years ago."

Nodosaur tracks are rarely found in the U.S., according to Stanford.
