Fig. 2 in Hindlimb morphology of Palaeotis suggests palaeognathous affinities of the Geranoididae and other "crane-like" birds from the Eocene of the Northern Hemisphere

Fig. 2. Tibiotarsi of palaeotidid, geranoidid, eogruid, and struthionid birds. A. Palaeotis weigelti Lambrecht, 1928 (Palaeotididae) from the middle Eocene of the Geiseltal, Germany, GMH XXXVIII-6-1964; distal end of right tibiotarsus in cranial (A1, A2), medial (A3, A4), and distal (A5) views; in A2 and A4 surrounding matrix was digitally removed, the dotted line in A4 indicates the reconstructed outline of the missing caudal portion of the condylus medialis. B. Palaeogrus princeps Portis, 1885 (?Palaeotididae) from the middle Eocene of Italy; distal end of left tibiotarsus in cranial (B1), medial B2), and distal (B3) views (from Portis 1885; mirrored). C. Galligeranoides boriensis Bourdon, Mourer-Chauviré, and Laurent, 2016 (Palaeotididae) from the early Eocene of southern France, paratype: MHNT.PAL.2013.16.1; distal end of right tibiotarsus in cranial view (from Bourdon et al. 2016). D. Galligeranoides boriensis Bourdon, Mourer-Chauviré, and Laurent, 2016 from the early Eocene of southern France, holotype, MHNT.PAL.2013.16.3; distal end of right tibiotarsus in cranial view (from Bourdon et al. 2016; mirrored). E. Eogrus aeola Wetmore, 1934 (Eogruidae), AMNH 2946; distal end of right tibiotarsus in cranial view (mirrored). F. cf. Eogeranoides campivagus Cracraft, 1969 from the early Eocene of Wyoming, USA, AMNH 5127; distal end of right tibiotarsus in cranial (F1) and medial (F2) views (mirrored). G. Palaeophasianus meleagroides Shufeldt, 1913 (Geranoididae) from the early Eocene of Wyoming, USA, holotype, AMNH 5128; distal end of left tibiotarsus of in cranial (G1) and medial (G2) views (mirrored). H. Extant Struthio camelus Linnaeus, 1758 (Struthionidae), SMF 2438; distal end of right tibiotarsus in cranial (H1) and medial (H2) views. Scale bars 10 mm (for B scale is based on measurements in Portis 1885).
