The bone displays adult features including a distinct crista and fossa trochanteris, articular facet for the antitrochanter, and femoral head with the neck and the fovea ligamentum capitis developed, but it is clearly immature in that the exposed shaft is densely covered with short, fine striations, the fossa trochanteris is spongy, and the head retains dense, fine pores.

) skeletons. The developmental stage of the fossil most closely matches that of a condor that died at 136 days old (USNM BIRDS 658188), in which the femur is likewise at or close to full adult size and form, has a finely striated shaft, dense pores on the femoral head, and the fossa trochanteris still spongy. The fossil femur is more advanced developmentally than a bird that died at 80 days old (USNM BIRDS 658191), which has not attained adult size and has the articular ends not fully formed or ossified. In two older condor chicks that died ten or fifteen days after the usual age of fledging (AMNH 32153, 184 days, and USNM BIRDS 658221, 187 days), the surface of the femoral shaft has attained the smooth surface texture and rugose topography seen in adult birds, although both femora retain some porous structure on the proximal articular surface.
