discovery site Bilzingsleben) is a former stone quarry in Thuringia, Germany, notable for its wealth of palaeolithic human fossils and artifacts.

The emerging spring waters in turn have dissolved the local calcareous rocks and formed the interglacial travertine deposits that cover the Bilzingsleben site.

The site itself was part of a fluvial terrace in Pleistocene, Central European river basin now situated 1.5 km (0.93 mi) south of the village of Bilzingsleben, Sömmerda district at 175 m (574.15 ft) above sea level in an old travertine quarry, called Steinrinne, where travertines have been quarried since early modern times and the material was used in the towns of the region, for example Kindelbrück's city wall.

In 1710 David Siegmund Büttner published his book "Rudera diluvii testes i.e. Zeichen und Zeugen der Sündfluth" (Signs and witnesses of the flood).

Under the auspices of the Halle State Museum of Prehistory a systematic excavation was launched in 1971 that lasted until 1992 during which 1,600 m2 (17,222.26 sq ft) were documented and several human fossils were unearthed.

The first phase (limnic chalk mixed with travertine sand) is dominated by hazel (Corylus), ash (Fraxinus) and oak (Quercus).

The second phase (pure limnic chalk) is dominated by hornbeam (Carpinus), alder (Alnus) and pine (Pinus).

Among the mammals are: Woodland animals predominate, but there are some species that prefer more open habitats as well, like rhinoceros, horse and bison.

One bone fragment, an elephant tibia, has two groups of 7 and 14 incised parallel lines and might represent an early example of art.

The regular spacing of the incisions, their subequal lengths and V-like cross-sections suggest they were created at the same time, with a single stone tool.
