Grand Canyon Trip #11

Zion National Park.

Cottonwoods at Zion National Park.

Tracks of a small upright dinosaur in sandstone south of Zion National Park. Paleontologists believe this might be the small carnivorous dinosaur (Megapnosaurus) that walked through this Jurassic marshland area about 200 million years ago. It may have hunted in packs. Bones of this species have been found in Arizona.
