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."
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"), 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 (2003), however, supported Elżanowski's naming of a new genus.
