A dry wash full of 112-million-year-old dinosaur tracks that include prints left behind by an ankylosaurus, dromaeosaurus and a menacing ancestor of the Tyrannosaurus rex, are set to be opened to the public this fall near Moab, Utah.
Utah Bureau of Land Management paleontologist ReBecca Hunt-Foster says there are more than 200 tracks in an area smaller than a football field.
They were first discovered in 2009. Since then, paleontologists led by a team at the University of Colorado at Denver have studied them and prepared them for display. It's set to open in October.
The tracks are from the early Cretaceous period. They include a set of 17 consecutive footprints left by Tyrannosaurus rex ancestor and the imprint of an ancient crocodile pushing off into the water.
