Specimens of Archaeopteryx 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, twelve body fossil specimens of "Archaeopteryx" and a feather that may belong to it have been found, though one of these specimens was reassigned to another genus by two researchers in 2017.
