Tyrannosaurus rex, often abbreviated as T. rex, was a large theropod dinosaur that lived during the Late Cretaceous period, approximately 68 to 66 million years ago. It is one of the most well-known and studied dinosaur species. T. rex was a bipedal carnivore, meaning it walked on two legs and ate meat. Its massive size, powerful jaws, and sharp teeth made it an apex predator in its ecosystem.

Fossils of T. rex have been found in western North America, primarily in the United States and Canada. The average adult T. rex is estimated to have been around 12 meters (40 feet) long, with a height of about 4 meters (13 feet) at the hips. Its skull was remarkably large, measuring up to 1.5 meters (5 feet) in length. The teeth were serrated and could grow up to 30 centimeters (12 inches) long, including the root.

The diet of T. rex is a subject of ongoing scientific research. Evidence suggests it preyed on large herbivores like hadrosaurs and ceratopsians, but it may have also scavenged carcasses. Its forelimbs were notably small, with only two functional digits, leading to much speculation about their purpose. T. rex went extinct along with all other non-avian dinosaurs during the Cretaceous-Paleogene extinction event.
