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.
