The quarrying of this lithographic limestone subsequently yielded spectacular finds, including Archaeopteryx, commemorated in the bird's full name Archaeopteryx lithographica. All 13 known specimens have come from the Solnhofen area.GeographySolnhofen is located on the Altmühl in Bavaria. It contains two districts: Hochholz and Eßlingen.
