Jurassic World is the long-awaited next installment of the groundbreaking Jurassic Park series. T. rex's, velociraptors, triceratops--as well as some all-new dinosaurs--will roar across the screen in this epic action-adventure directed by Colin Trevorrow starring Chris Pratt, Bryce Dallas Howard, Ty Simpkins and Nick Robinson! Was Tyrannosaurus rex a speedy and savage hunter, or was it a slow-moving scavenger, surviving on scraps left from other dinosaurs' kills? World renowned tyrannosaur expert Dr. Thomas R. Holtz, Jr., shares the evidence on both sides of the argument in this easy-to-read, easy-to-understand Step into Reading book that young dinosaur enthusiasts will heartily devour.
