About Siats
What it was like
Siats was a large two-legged meat eater known from part of one skeleton. It was probably a megaraptoran, a group of hunters with big hand claws, though scientists disagree about where it fits.
Its world
It lived in the Late Cretaceous, around 94 million years ago, in what is now Utah. Its bones come from the Cedar Mountain Formation. At the time, tyrannosaurs in North America were still small, and Siats may have been one of the top hunters.
How it was found
Zanno and Makovicky named Siats in 2013. The name comes from a monster in the legends of the local native people. Only one find is known.
