Wellnhoferia
Wellnhoferia (named after Peter Wellnhofer) 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 (2001) of the Institute of Zoology of the University of Wrocław, Poland, determined the differences resulted from a "phylogenetic reduction rather than individual variation."[1]
The type specimen is the Solnhofen Specimen of Archaeopteryx (BSP 1999). Discovered in the 1960s near Eichstätt, Germany and described in 1988 by Wellnhofer (as a specimen of Archaeopteryx),[2] 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. [3] found Wellnhoferia was a specimen of Archaeopteryx lithographica. Senter and Robins (2003), however, supported Elżanowski's naming of a new genus.[4]
