Anchiornithidae is a family of small paravian dinosaurs.^[1] Anchiornithids have been classified at varying positions in the paravian tree, with some scientists classifying them as a distinct family, a basal subfamily of Troodontidae,^[2]^[3]^[4]^[5] members of Archaeopterygidae,^[2]^[6] or an assemblage of dinosaurs that are an evolutionary grade within Avialae^[7] or Paraves.^[8]
