Peter Wellnhofer Peter Wellnhofer Peter Wellnhofer (born Munich, 1936) is a German paleontologist at the "Bayerische Staatssammlung fur Paläontologie" in Munich. He is best known for his work on the various fossil specimens of "Archaeopteryx" or "Urvogel", the first known bird. Wellnhofer's other work includes "The Illustrated Encyclopedia of Pterosaurs". "Wellnhoferia", a bird closely related to "Archaeopteryx", or a species of the Urvogel itself, was named in his honor. In 2007 a special meeting of pterosaur experts in Munich was dedicated to Wellnhofer, describing him as "the foremost authority on pterosaurs for the last four decades." The meeting produced a festschrift in
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.

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
