Tyrannosaurus rex (order Saurischia, suborder Theropoda) A giant, carnivorous dinosaur which lived during the Upper Cretaceous in N. America and possibly in Asia. Individuals grew to 12 m in length, 5 m tall, and weighed about 7 tonnes. The name means ‘king of the tyrant lizards’, but T. rex was probably a scavenger with a top speed of 16–40 km/h.
