From: On the taxonomy and osteology of the Early Eocene North American Geranoididae (Aves, Gruoidea)
Left leg of a geranoidid from the Early Eocene (Wasatchian) Willwood Formation of the Bighorn Basin in Wyoming, USA (AMNH 5127; cf. “Eogeranoides campivagus”). The specimen consists of various fragments that were assembled for the photo. a Left tibiotarsus and femur. Left tarsometatarsus in b lateral and c dorsal view. The misalignment of the midsection of the shaft is due to the preservation of the fossil fragments. d Distal end of the tarsometatarsus of AMNH 5127 as figured by Shufeldt (1913: fig. 78). e Distal tarsometatarsus of AMNH 5127 as it is now after preparation. Right tarsometatarsus of Eogrus aeola (AMNH 2937) from the Middle Eocene Irdin Manha Formation of the Shara Murun region in Inner Mongolia (China) in f dorsal and g plantar view. h Detail of distal end in dorsal view. In d, e, and h, the trochleae are numbered. Scale bars 10 mm for d, e, and h, and 50 mm for a–c, f, and g
