This is Tyrannosaurus rex, a meat-eating dinosaur from the Late Cretaceous. Look at its huge head, powerful hind legs and two very short front limbs.
Classification used here: Tyrannosaurid theropod dinosaur. Fossils assigned to Tyrannosaurus rex are known from Late Cretaceous (about 68–66 million years ago) and have been found in western North America (United States and Canada). The museum uses 11.5–13 m (about 38–43 ft) as the reference body length and describes the diet as meat-eater. Tyrannosaurus rex was a giant theropod dinosaur. Fossils show a huge skull, robust teeth and short, two-fingered front limbs. Scientists still debate exactly how those front limbs were used. This exhibit focuses gently on the animal’s shape and does not show hunting.

I’m Leon, a developer and a dad. When my daughter was three, dinosaur chases on television frightened her, so I made a 3D prehistoric animal museum where she could look quietly and listen only when she wanted to.
The museum is free, with no sign-up, adverts or visitor tracking. Finding one interesting detail at a time is plenty.
