Wellnhoferia
Wellnhoferia is a genus of early prehistoric bird-like theropod dinosaur closely related to Archaeopteryx. It lived in what is now Germany, during the Late Jurassic. While Wellnhoferia was similar to Archaeopteryx, it had a shorter tail and its fourth toe was shorter than in Archaeopteryx. Andrzej Elżanowski of the Institute of Zoology of the University of Wrocław, Poland, determined the differences resulted from a "phylogenetic reduction rather than individual variation."
The type specimen is the Solnhofen Specimen of Archaeopteryx. Discovered in the 1960s near Eichstätt, Germany and described in 1988 by Wellnhofer, it is currently located at the Bürgermeister-Müller-Museum in Solnhofen. It was originally classified as a Compsognathus by an amateur collector.
Although Elżanowski found significant differences between Wellnhoferia and Archaeopteryx, a 2007 study by Mayr et al. found Wellnhoferia was a specimen of Archaeopteryx lithographica. Senter and Robins, however, supported Elżanowski's naming of a new genus.
