Field notes

About Gualicho

What it was like

Gualicho was a large two-legged predator with very short arms and only two fingers, much like a tyrannosaur. It was not a close relative of the tyrannosaurs, so short arms seem to have evolved several times.

Its world

It lived in the Cretaceous, in what is now Argentina. It comes from the Huincul Formation, where it shared the land with the giant predators Mapusaurus and Meraxes, the abelisaur Skorpiovenator and the huge sauropod Argentinosaurus.

How it was found

Apesteguia and colleagues named Gualicho in 2016. Its name comes from a spirit of local folklore, since the dig had bad luck.
