Specimens of Archaeopteryx original classification of a new taxon, "Archaeopteryx bavarica". The hind limbs, while showing no morphological differences from previously known specimens, were perhaps the best preserved yet and showed some unprecedented details. For example, the right foot was preserved so tightly flexed that the claws of the first and fourth toes are overlapping, indicating that a grasping or perching function was present in "Archaeopteryx", possibly as sophisticated as that of modern birds. Only the imprints of wing and tail feathers are present, and all sign of feathers comes from the counterslab. No body feathers are evident. The right wing displays a
Specimens of Archaeopteryx "Archaeopteryx" likely indicated it had very little flight ability. The furcula (wishbone) is well-preserved and lies between the scapulae; its boomerang-like shape reveals a 75-degree angle between its branches. De Beer identified a compressed mass of bone as a sternum in the London specimen, but later researchers disputed this as more likely to be a concretion of vertebrae encrusted by calcite. That "Archaeopteryx" lacked a bony sternum is in agreement with the modern consensus that many specimens of "Archaeopteryx", including the London, likely represented immature animals whose sterna were still cartilaginous. The pelvic girdle is separated into its three components
