English: Imperobator is a paravian theropod from the Late Cretaceous of Antarctica. Most of the body is unknown, but it is estimated that Imperobator was around 2 m tall. This shows that it exhibited gigantism, a trait not often seen among paravians. Despite prior assignment to Dromaeosauridae, Imperobator has since been assigned to the clade Paraves due to certain characteristics that differ from those of dromaeosaurids, including the lack of a sickle claw. Based on evidence from other paravians, Imperobator likely had a feathery covering on most of its body. It was probably carnivorous, however it is unclear whether it scavenged or hunted its prey.
