Imperobator ("powerful warrior") is a genus of paravian theropod that lived during the Maastrichtian stage of the Late Cretaceous period in what is now Antarctica. It contains a single species, I. antarcticus, recovered from the Snow Hill Island Formation.[1] Before its description, it was informally nicknamed the "Naze dromaeosaur", despite the lack of a "sickle claw" characteristic of the group. In 2019, the describing authors suggested that Imperobator was about the same size as Utahraptor.
