A large broken lower jaw of Homo erectus or pre-Neanderthaler type found in the Mauer sands near Heidelberg, Germany. It is dated to either the Mindel Glaciation or the Günz-Mindel Interglacial - probably the latter. No tools were recovered from the stratum, but there was associated fauna (elephant, rhinoceros, bear, horse, saber-toothed cat). Although it dates from perhaps 400,000 years ago, it is not very different from the Neanderthals of c 50,000 years ago.
