Named the “king of the tyrant lizards,” T. rex was built to rule. "Tyranno" means tyrant in Greek; "saurus" means lizard in Greek; and "rex" translates to "king" in Latin. T. rex was a member of the Tyrannosauroidea family of huge predatory dinosaurs with small arms and two-fingered hands. It was a giant carnivore and primarily ate herbivorous dinosaurs, including Edmontosaurus and Triceratops. The predator acquired its food through scavenging and hunting, grew incredibly fast, and ate hundreds of pounds at a time.
