Dinosaur senses primitive birds like "Archaeopteryx" and "Hesperornis". The optic nerve was large in "Carcharodontosaurus". Among dinosaurs, theropods had exceptionally large eyes. Deinonychosaurians, especially troodontids, had forward-facing eyes, suggesting stereoscopic vision and improved depth perception. Tyrannosauroid snouts allowed for a 55˚ binocular field of view, less than a modern human but more than their hadrosaurid prey. Dinosaur senses Dinosaur senses are difficult subjects of study for paleontologists since soft tissue anatomy rarely fossilizes. The three semicircular canals of the inner ear of "Allosaurus fragilis", when viewed from the side, had a subtriangular outline. This subtriangular inner ear configuration is present in "Carcharodontosaurus",
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
