The wing phalanges (Phalanx proximalis digiti majoris) of European Accipitriformes and Falconiformes

The authors compared the first phalanx of the second wing finger of 33 European diurnal raptors. The importance of studying this bone lies in the fact that, although it has diagnosable characteristics, it was practically neglected by osteologists and paleontologists. Thus, fossil materials can be id...
