Eubrontes Dinosaur Footprint

Caption

This Eubrontes dinosaur footprint -- including three toes and a heel -- measures roughly 16 inches long. Dinosaur footprints are named by their shape because the species and genus of animal that made them isn’t known, although Eubrontes tracks are believed to have been made by upright-walking, meat-eaters smaller than Tyrannosaurus rex. Eubrontes is one of four types of dinosaur footprints identified by University of Utah geologists at a Jurassic Period dinosaur "trample surface" in northern Arizona. The footprints previously had been thought to be modern potholes eroded by water. The inset outlines the footprint shape.
