Archaic Homo sapiens. Homo antecessor Homo heidelbergensis Homo neandertalensis. Archaic Homo.
This mandible was found by a workman in the Rösch sandpit just north of the village of Mauer near Heidelberg, Germany, in 1907. The workman showed the find to the anatomist O. Schoentensack, who provided the initial description of the specimen. The mandible is complete with only the premolars and first two molars on the left side missing. The molars were recovered separately, although the premolars were lost.
The braincase profile is low and slopes back from a large supraorbital torus reminiscent of earlier H. erectus specimens.
There is also the remnant of a sagittal keel and an occipital torus at the back of the skull, also recalling H. erectus. However, the face is more modern in appearance (less prognathic, flatter) and the brain size of about 1300 cc. is larger than seen in H. erectus.
Thus, this cranium preserves many traits that are reminiscent of earlier H. erectus and hints of more modern traits known later in H. sapiens.
