Diagnosis

|---|---|---|
| M. Stucchi et al. 2015 | The specimen is recognized as belonging to a species in Cathartidae in having a deep fossa infracotylaris dorsalis and sulcus extensorius, a large eminentia intercotylaris, and a crista plantaris medialis that extends distally approximately one-third the length of the shaft and by the shape and relative position of the trochleae (sensu Emslie, 1998). The specimen MUSM 2423 is identified as representing a species of condor that is distinguished from smaller vultures (Cathartes, Coragyps) and Sarcoramphus by its large size and prominent eminentia intercotylaris. The fossil speci- men differs from tarsometatarsi of other fossil and extant condors (the species in Gymnogyps, Breagyps, Geronogyps, Perugyps, Vultur, Aizenogyps, and Hadrogyps) by (1) shaft long and relatively narrow, with total length and proximal width exceeding all known species; (2) distinct fossa infracotylaris dorsalis and sulcus extensorius on the proximal half of shaft, with upper third relatively larger and deeper than in
all other species, and with minute foramina vascularia proxi- malia; (3) hypotarsus in plantar view forms a plate that is deeper than wide; and (4) trochlea metatarsi III with proximodistally long anterior articular surface that tapers proximally, with the proximal edge nearly reaching the height of the canalis interosseus distalis. |
