A Tyrannosaurus rex, a massive, meat-eating dinosaur with huge jaws, tiny arms, and a long tail. Depicted as a green tyrannosaur standing on its hind lefts facing left, often with a textured back, sharp teeth, and clawed toes.

May be used to represent various dinosaurs, including raptors. See also 🦕 Sauropod.

May also be used to call a person a dinosaur, i.e. imply that they are old-fashioned or out-of-touch with modern sentiments.

Google’s T-rex used to look somewhat like a velociraptor, though the design has since changed. Samsung’s T-Rex was previously red, Microsoft's brown, and Facebook’s only a green head with open jaws.

T-Rex blev godkendt som en del af Unicode 10.0 i 2017 og føjet til Emoji 5.0 i 2017.
