Scientists have discovered a track from a three-toed dinosaur said to be about 70 million years old, in the Denali national Park, in Alaska.

According to an Associated Press report, a University of Alaska Fairbanks student first discovered the footprint on June 27, while taking a geology field course.

The fossil is 9 inches long and 6 inches wide.

Anthony Fiorillo, curator of earth sciences at the Dallas Museum of Natural History has assigned greater importance to the discovery.

"It's not necessarily the track itself that's significant," the Associated Press quoted Fiorillo as saying, "It's where it is that's got us all excited." Fiorillo guessed the dinosaur was 9 to 13 feet long.

"You are looking at a very large, birdlike animal except it has teeth and a tail and instead of wings, it has arms," Fiorillo continued.

The Associated Press reports that Susi Tomsich, an undergraduate at the University of Alaska Fairbanks, noticed the track on the underside of a ledge.
