For instance, it has a long ascending process of the ankle bone, interdental plates, an obturator process of the ischium, and long chevrons in the tail. In particular, Ostrom found that "Archaeopteryx" was remarkably similar to the theropod family Dromaeosauridae. Specimens of "Archaeopteryx" were most notable for their well-developed flight feathers.
Specimens of Archaeopteryx Justice in Karlsruhe, which upheld the Superior District Court's decision in 2003, bringing a 14-year lawsuit to a close and earning the sixth "Archaeopteryx" specimen its name of Solnhofen. The Solnhofen specimen represents the largest "Archaeopteryx" individual known. It is represented by a nearly-complete skeleton on a plate sized 39 x 52 cm. There is no counterslab associated with this specimen. The skeleton shows a death posture typical of theropods and especially similar to that of the Eichstätt specimen. The animal's carcass was likely deposited and buried completely articulated. Despite the specimen's skeletal completion, plumage traces are very faint and
