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
Dinosaur vision Dinosaur vision Dinosaur vision was, in general, better than the vision of most other reptiles, although vision varied between dinosaur species. Coelurosaurs, for example, had good stereoscopic or binocular vision, whereas large carnosaurs had poor binocular vision, comparable to that of modern alligators. Most carnosaurs, including "Carcharodontosaurus" and "Allosaurus", did not have very good binocular vision, comparable to modern alligators. They possessed binocular vision which was restricted to a region only 20° wide, which is understandable, as they hunted mostly large and slow prey. Their keenest sense was probably smell. Deinonychosaurs, like "Stenonychosaurus" and "Velociraptor", had better binocular vision than
