Tyrannosaurus rex

T. rex on a charge, jaws agapeTyrannosaurus rex was a giant theropod that lived in North America in the Late Cretaceous Period, during the very last years of the Age of Dinosaurs. Longer than the width of a doubles tennis court, it was one of the largest flesh-eating animals ever to walk on Earth. An eight-year old child could have stood in its gaping mouth, surrounded by rows of dagger-like, saw-edged teeth, some up to 18 centimetres (7 inches) long. Relying on its keen senses of sight, smell and hearing, T. rex hunted or scavenged for its food.

Hunting technique

Using its excellent sense of smell, T. rex would pick up the scent of a herd of Triceratops. Following at a distance and out of sight, it would look out for stragglers: the young, old or injured. When one was spotted, it would get as close as possible before rushing at it, jaws gaping, overcoming its prey with the force of its attack. It would then hold it down with its arms or feet before delivering a fatal bite to its neck.

The name Tyrannosaurus means “tyrant lizard”; rex means “king”. It is the only dinosaur commonly known by its full scientific name.
