Dinosaurs have come to life at Hogle Zoo, as 13 animatronic dinosaurs that roar, move, snarl and spit settle in for the summer. The life-size dinosaurs include an Allosaurus as well as a Tyrannosaurus rex, Styracosaurus, Kentrosaurus, Megalasourus, Suchomimus, Dilophosaurus and a Brachiosaurus. The Zoorassic Park display opens Saturday and will continue through August 21.
