       The name Orkoraptor is derived from‭ '‬Orr-Korr‭' ‬the Aoniken name for the La Leona River of Argentina.When first described,‭ ‬Orkoraptor was thought to be a coelurosaur thus a possible tyrannosauroid.‭ ‬However later studies have since caused this notion to be dismissed as Orkoraptor seems to actually be a form of late surviving allosaurid.‭
       It's possible that the geographic isolation‭ ‬of South America from the rest of the world during the Cretaceous may have protected the lineage that led to Orkoraptor from other newly appearing forms.‭ ‬This is also reflected in the fact that Orkoraptor is one of the southernmost carnivorous dinosaurs that have been discovered in South America.‭ ‬Unless future fossil finds prove otherwise,‭ ‬Orkoraptor may have been restricted to the south due to the abundance of carcharodontid and abelisaurid theropods further north.
