Tyrannosaurus Rex: A Complex Dinosaur

Tyrannosaurus Rex, represented by a skull and a tooth in the Earth Sciences Museum, was a fierce carnivorous predator and scavenger that lived in the late Cretaceous, 68 - 66 million years ago. Weighing in at over 7 tons, over 4 metres tall at its hips and 12 metres in length, it is one of the most recognizable dinosaurs19. It is a lizard hipped, or Saurischian, dinosaur. Although it is often portrayed as a predator, it also scavenged, similar to many modern mammals4. Over 50 specimens have been identified throughout Western North America, which was known as the island continent of Laramidia when T. rex roamed the earth18. Its large skull was balanced by its long, heavy tail, with short powerful limbs. Its two claws made it easy to tear through
