 In this analysis, "Austroraptor" is found to be a more basal member of Unenlagiinae.It has been suggested that unenlagiines had better capacities for running and pursuit predation than other dromaeosaurids.While Laurasian dromaeosaurids (Eudromaeosauria) were more stocky and had shorter legs and had an active predatory lifestyle, unenlagiines could likely maintain high speeds for extended amounts of time because they were more gracile.
