Only 13 specimens of Archaeopteryx - and one special feather - are known to exist since the first Archaeopteryx fossils were discovered in 1860. Almost all come from the same deposit of Solnhofen Limestone in Bavaria, Germany - rock that began to form when the region was covered by a shallow prehistoric sea. Most of the specimens are housed in German institutions, some are in the hands of private collectors, and one has gone missing.
