Tyrannosaurus rex is probably the most familiar dinosaur in history. Its name means 'tyrant lizard king' and to many it represents the ultimate predator. This magnificent animal has long been at the heart of dinosaur attractions. This bipedal carnivore is known for its massive head with what is theorized as one of the strongest bites to have ever existed on land.
Tyrannosaurus rex fossils have been found across the once island continent of Laramidia – now western North America. Teeth were the first fossil find in 1874 near Golden in Colorado. The largest skeleton find so far was by Sue Henrickson at the Hell Creek Formation in South Dakota.
Tyrannosaurus rex ranged across a number of different ecosystems. These vary between inland and coastal subtropical regions, and semi-arid plains. To the north it is considered the dominant predator, but to the south Alamosaurus dominated.
