American Archaeoptery-X

The Thermopolis-specimen, after the actual location in the Wyoming Dinosaur Centre, Thermopolis, is one of the best preserved fossils of Archaeopteryx, and the X-th in the order. The finding circumstances are unknown, in 2001 it was offered for sale, presumably by a private Swiss collector, first to the German museum of Senckenberg, but the costs were to expensive. It was so acquired by the Dinosaur Centre, finally described and presented in 2005 to the public. In this specimen the second toe is notable, like in the Deinonychosauria it could be stretched backwards.
