Saurornitholestines

Saurornitholestines are dinosaurs in the subfamily Saurornitholestinae of the theropod group Dromaeosauridae. The saurornitholestines currently include 3 monotypic genera: Atrociraptor marshalli, Bambiraptor feinbergorum, and Saurornitholestes langstoni. All are medium-sized dromaeosaurs from the Late Cretaceous of western North America. The group was originally recognized by Longrich and Currie as the sister taxon to a clade formed by the Dromaeosaurinae and Velociraptorinae. However, not all phylogenetic analyses recover this group and/or with the same proposed genera.
