Site near Stuttgart, Germany, where a human skull was discovered in gravels of the Holsteinian (penultimate) interglacial some 250,000 or 300,000 years ago. No artifacts were found, but the Steinheim skull is older than any Neanderthal or Homo sapiens skeleton, and is closer to the Swanscombe skull than to any other specimen. The Steinheim and Swanscombe skulls may belong to a distinct subspecies of Homo, but have also been classified as early Neanderthaloids or primitive Homo sapiens.
