Humans and Tyrannosaurus never interacted at any time. Researchers still debate whether this dinosaur scavenged more frequently, or primarily hunted live prey. This allowed them to feed on the carcasses of large dinosaurs, and more efficiently kill prey. Scientists believe that T-rex had the strongest bite of any terrestrial animal known to man. This is because they would have required large amounts of food to maintain such a large size, and likely couldn’t afford to be picky. These reptiles likely fed on a wide variety of prey. Archaeologists have found seven specimens in Montana, four in South Dakota, one in Wyoming, and one in Saskatchewan. This does not necessarily mean that these creatures did not roam the entire American continent, but simply that these areas met conditions for fossilization. There are thirteen known specimens, all of which hid under the earth in the United States and Canada. Researchers found all of the Tyrannosaurus rex fossils today in North America. These water sources likely attracted wide variety of prey for these carnivores to feed on. They lived in coastal swamps, open forests, and likely remained close to water sources. Scientists believe that the T-rex lived in areas with high humidity and semi-tropical temperatures. The landscape of their range was very different 65 million years ago, as was much of the world. These dinosaurs likely utilized a wide range of habitats. The Tyrannosaurus had jaws lined with sharp teeth, which could grow up to 12 in. In fact, their head was disproportionately large, and required an extremely muscular neck to support it. This creature had an impressively large head.
