MONDAY, AUGUST 25, 2014 HEALTH & SCIENCE Dinosaur footprints set for public display in Utah

SALT LAKE CITY: A dry wash full of 112-million-year- old dinosaur tracks that include an ankylosaurus, dromaeosaurus and a menacing ancestor of the Tyrannosaurus Rex, is set to open to the public this fall in Utah. There are more than 200 tracks near the city of Moab from 10 different ancient animals that lived during the early Cretaceous period, said Utah Bureau of Land Management paleontologist ReBecca Hunt-Foster. They were first discovered in 2009 by a resident. Since then, paleontologists led by a team at the University of Colorado at Denver have studied them and prepared them for display. The tracks include a set of 17 consecutive footprints left by WASHINGTON: Panda cub Bao Bao licks her birthday cake at the National Zoo in Tyrannosaurus rex ancestor and the imprint of an Washington. — AP photos ancient crocodile pushing off into the water.
