Specimens of Archaeopteryx
''Archaeopteryx'' fossils from the quarries of Solnhofen limestone represent the most famous and well-known fossils from this area. They are highly significant to paleontology and avian evolution in that they document the fossil record's oldest-known birds.〔
Over the years, eleven body fossil specimens of ''Archaeopteryx'' and a feather that may belong to it have been found. All of the fossils come from the upper Jurassic lithographic limestone deposits, quarried for centuries, near Solnhofen, Germany.〔〔(National Geographic News- ''Earliest Bird Had Feet Like Dinosaur, Fossil Shows'' ) - Nicholas Bakalar, 1 December 2005, Page 1.

== The feather ==
The initial discovery, a single feather, was unearthed in 1860 or 1861 and described in 1861 by Christian Erich Hermann von Meyer. The fossil consists of two counterslabs, designated BSP 1869 VIII 1 (main slab) and MB.Av.100 (counterslab). Its two counterslabs are currently located at the Bavarian State Collection of Paleontology and Geology of Munich University and the Museum für Naturkunde in Berlin, respectively.〔 This feather is generally assigned to ''Archaeopteryx'' and was the initial holotype, but whether it actually is a feather of this species or another, as yet undiscovered, avialan is unknown. There are some indications it is indeed not from the same animal as most of the skeletons (the "typical" ''A. lithographica'').
