Saurornitholestinae Explained

Saurornitholestinae is a subfamily of the theropod group Dromaeosauridae. The saurornitholestines currently include monotypic genera Atrociraptor marshalli, Saurornitholestes langstoni, and possibly Bambiraptor feinbergi and Acheroraptor temertyorum. 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.^[1] However, not all phylogenetic analyses recover this group and/or with the same proposed genera.^{[2] [3] [4]}

Classification

Below are the results for the Eudromaeosauria phylogeny based on the phylogenetic analysis conducted by Jasinski and colleagues in 2020 during the description of Dineobellator. The group was recovered, but this time with the exclusion of Bambiraptor which is recovered as a sister taxon of Eudromaeosauria:^[5]
