Siats (/see-ats/) is an extinct genus of large theropod dinosaur known from the Late Cretaceous Cedar Mountain Formation of Utah, United States. It contains a single species, Siats meekerorum.[1][2] It was initially classified as a megaraptoran, a clade of large theropods with very controversial relationships. Siats may be a neovenatorid allosauroid,[1] a coelurosaur of uncertain phylogenetic position,[3] or a tyrannosauroid. Recent studies suggest however a carcharodontosaurid classification.[4]
