Henry Fairfield Osborne, president of the American Museum of Natural History, named Tyrannosaurus Rex in 1905. The generic name is derived from the Greek words meaning “tyrant”and sauros, meaning “lizard. Osborn used the Latin word Rex meaning “king”, for the specific name.
The full binomial therefore translates to “tyrant lizard the king” or “King Tyrant Lizard”, emphasising the animal’s size and perceived dominance over other species of the time.
