Tyrunt is a small reptilian dinosaur-like Pokémon that resembles a young Tyrannosaurus Rex. Its rocky scales are brown, and it has a gray lower jaw and underbelly. Tyrunt has a very large head and a gaping maw with four sharp fangs. Its arms and claws are tiny compared to its size. It has a fringe of white spiny scales around its neck, two orange spikes atop its head, and one orange spike on its tail. It has large and powerful hind legs with three long, sharp claws on each.
In order to obtain Tyrunt, it must be resurrected from the Jaw Fossil. Tyrunt evolves into Tyrantrum starting at level 39 during the day.
