It could run on two legs or walk on four legs, weighed approximately 7,000 to 8,000 pounds and reached up to 40 feet in length. The actual fossilized dinosaur that the museum’s bronze cast is based upon was discovered in South Dakota in 1995 by paleontologists.
Did T Rex eat Edmontosaurus?
T. rex was a huge carnivore and primarily ate herbivorous dinosaurs, including Edmontosaurus and Triceratops. The predator acquired its food through scavenging and hunting, grew incredibly fast and ate hundreds of pounds at a time, said University of Kansas paleontologist David Burnham.

How did T. rex mate?
Due to certain size constraints, the fearsome Tyrannosaurus Rex was unable to, say, take a mate into his arms. Instead, he was left with his nose, which out-extended his arms, to perform such “pre-copulatory play,” as the scientists said.

Do dinosaurs Still Exist?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
How did hadrosaurs chew?
Hadrosaurs had teeth arranged into what are called dental batteries – rows of stacked teeth designed for crushing and grinding tough, fibrous plant matter to increase its digestibility. These tooth batteries could contain up to 300 individual teeth in each part of the jaw!
Did hadrosaurs chew their food?
The tooth scratches also reveal how hadrosaurs chewed. A novel analysis of microscopic scratches on fossilized teeth reveals how plant-eating duck-billed dinosaurs used a now-extinct type of jaw to chew their food.

Friendliest Dinosaurs: Stegosaurus
The Stegosaurus is one of the friendliest dinosaurs to have ever been discovered. The Stegosaurus was a lizard-like, herbivorous dinosaur that lived in areas around the United States and Portugal between 155 and 150 million years ago.
