Siats

Siats is an extinct genus of large megaraptoran theropod dinosaur known from the Late Cretaceous Cedar Mountain Formation of Utah, US. It contains a single species, Siats meekerorum. S. meekerorum would be the first neovenatorid discovered in North America and the geologically youngest allosauroid yet discovered from the continent. However, recent phylogenetic analysis suggests that all megaraptorans are actually tyrannosauroids.
