About Tyrannomimus
What it was like
Tyrannomimus was an early ostrich-like dinosaur, a relative of Deinocheirus and Garudimimus. Some features of its skeleton look like those of tyrannosaurs, which gave it its name. It probably had long legs for running.
Its world
It lived in the Early Cretaceous in what is now Japan. Its bones come from the Kitadani Formation, a rich site shared with the predator Fukuiraptor, the plant eaters Fukuisaurus and Koshisaurus, and the sauropod Fukuititan.
How it was found
Hattori and colleagues named it in 2023 from one find. The type species is Tyrannomimus fukuiensis.
