1. Bird Track Marker
Inscription. Birds are descendants of theropod (meat-eating) dinosaurs and their tracks look similar: three long narrow toes with claw marks. However, bird tracks are generally smaller than most theropod tracks.

This print is wider than long and the toes are splayed. The fossil track here is a bird footprint.

Tracks made by wading birds are typically wider than long. Left and right footprints are mirror images.

Theropod tracks, like those found at Dinosaur Ridge, are consistently longer than they are wide. The toes are less splayed than those of birds and point forward. The left and right footprints are offset based on the walk of the animal while bird tracks are in a straight line.

 
Erected by The Greater Denver Area Gem and Mineral Council, the Rocky Mountain Association of Geologists, and the Friends of Dinosaur Ridge.
