Archaeopterygidae is a group of

troodontid.[3][4][5] A few studies have recovered Anchiornis and Xiaotingia (usually considered part of a distinct clade, Anchiornithidae) to also be members of the Archaeopterygidae,[6] though most subsequent analyses have failed to arrive at the same result. Uncertainties still exist, however, and it may not be possible to confidently state whether archaeopterygids are more closely related to modern birds or to deinonychosaurs barring new and better specimens of relevant species.[7] Teeth attributable to archaeopterygids are known from the earliest Cretaceous (Berriasian) Cherves-de-Cognac locality and the Angeac-Charente bonebed of France.[8][9]

Classification

The

phylogenetic definition for Archaeopterygidae was given by Xu and colleagues in 2011: the clade comprising all animals closer to Archaeopteryx than to the house sparrow or Dromaeosaurus.[6]

The family

cladistic definition of Archaeopterygidae explicitly excluded them.[11]

The family Anchiornithidae has had some of the members or the entirety of the group placed as archaeopterygids in various systematic studies.[6][12][1] The cladogram below shows the results of the phylogenetic analysis by Cau (2020).[1]
