How it got its name

Aside from being one of the largest of the known carnivorous dinosaurs, Tyrannosaurus rex — T. rex, for short — is the dinosaur that has arguably received the most media exposure. It had a starring role in the "Jurassic Park" movies and has a renowned exhibit at the American Museum of Natural History in New York City.


The name Tyrannosaurus rex means "king of the tyrant lizards": "tyranno" means tyrant in Greek; "saurus" means lizard in Greek, and "rex" means "king" in Latin. In 1905, Henry Fairfield Osborn, president of the American Museum of Natural History at the time, named Tyrannosaurus rex.T. rex was a member of the Tyrannosauroidea family of huge predatory dinosaurs with small arms and two-fingered hands.Tyrannosaurus rex, or “Tyrant Lizard”, one of the largest dinosaurs to have walked the earth, lived 70 million years ago in what is now North America. Weighing in at 7.5 tons, standing 15-20 feet tall and 40 feet long.


T. rex was a fierce predator! This dinosaur’s massive jaws were lined with 50-60 serrated teeth, some measuring 9 inches long. Preserved bone and muscle fragments in T. rex feces show that it took big, bone-crushing bites consuming up to 500 lbs of meat in one bite! Its 4-foot-long jaws were big enough to swallow an adult human!See this massive meat-eater along with seven other dinosaur species at Dinosaurs Come to Life, a special outdoor exhibit at Clyde Peeling’s Reptiland. Due to its popularity, Dinosaurs Come to Life has been extended through the end of October 2011.
