One specimen of this creature was controversially re-classified into the genus Wellnhoferia.
One specimen of this creature was controversially re-classified into the genus Wellnhoferia. All known remains of this prehistoric creature were discovered in the Solnhofen limestone deposits. This denizen of the Late Jurassic period was once thought to be closely related to Compsognathus, but is now thought to be more closely related to the dromaeosaurs. This creature lacked a breastbone, and thus was probably incapable of lifting its arms over its body and engaging in flapping, the process its descendents use for flying. For ten points, name this oldest known fossilized bird.
