Tyrannosaurus rex

Tyrannosaurus rex is a large coelurosaurid theropod from Late Cretaceous North America.

In Real life
The Tyrannosaurus is the most famous dinosaur ever known. It is one of the largest theropod dinosaurs known, with only Saurophaganax, Giganotosaurus, individual harcharodontosauruses, Mapusaurus, and Spinosaurus being longer, with only the Giganotosaurus, Mapusaurus, and Spinosaurus being heavier. Tyrannosaurus is popular mostly for once being the largest known theropod dinosaur and it's small, two fingered arms.

The Tyrannosaurus is one of the most well known theropods due to the large amounts of fossils of it found. Tyrannosaurus had no natural predators, and the only possible competition known was the much smaller Dakotaraptor and the oviraptorsaur Anzu. Tyrannosaurus is known to have hunted ceratopsians like Triceratops and Leptoceratops, and hadrosaurs like Edmontosaurus, Miasaura, and Lambeosaurus, Pachyycephalosaurus and it's possible young/relatives Stygimoloch and Dracorex, ankylosaurids like Denversaurus, Edmontia, and Ankylosaurus and the Ornithimimids Ornithomimus and Struthomimus.

Their is an ongoing debate whether Tyrannosaurus had feathers, one side pointing out that some some small patches of fossilized skin shows that the whole animal doesn't have feathers, while the other side argues that the skin impressions just showed it was less feathered than previously thought, with feathers only on the neck and around the shoulders.
