From: The earliest Tyrannida (Aves, Passeriformes), from the Oligocene of France
Right carpometacarpus of the Luberon fossil NT-LBR-014, compared with extant species (Pipridae). (b,c), inverted left carpometacarpi. In (c), the angle of view (ventral) is slightly different from that in (a,b,d) (slightly cranio-ventral, in (b) more than in (a,d)). *The facies articularis radiocarpalis is masked under the matrix. facies art. rad., facies articularis radialis; facies art. uln., facies articularis ulnaris; os met. maj., os metacarpale majus; os met. min., os metacarpale minus; proc. ext., processus extensorius; synos. met. dist., synostosis metacarpalis distalis. The angles of view prevent from seeing the processus dentiformis when present. Scale bars, 5 mm.
