is located on the northern border of the Thuringian Basin, a depression made of triassicKeuper. To the North are the Kyffhäuser mountains, Hainleite and Schmücke that contain mainly Bunter sandstone and Muschelkalk deposits. The regions are separated by the local hercynianfault-line. The fault-line is the cause for numerous springs in this area. The emerging spring waters in turn have dissolved the local calcareous rocks and formed the interglacial travertine deposits that cover the Bilzingsleben site. The 400.000 year long conservation is attributed to the travertine's remarkable resilience to erosional processes. The site itself was part of a fluvial terrace in Pleistocene, Central European river basin now situated south of the village of Bilzingsleben, Sömmerda district at 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.
History of the excavation
bones at the site had already been found since the 13th century. In 1710 David Siegmund Büttner published his book "Rudera diluvii testes i.e. Zeichen und Zeugen der Sündfluth". In 1818 Freiherr Friedrich von Schlotheim found a human skull covered by limeconcretions. It is lost today. In 1908 geologist Ewald Wüst of the University of Halle-Wittenberg published his first work on local flint artifacts. Amateur researcher Adolf Spengler took up work at the site in 1922. In 1969 Dietrich Mania, later professor at the University of Jena, discovered numerous fossils and artifacts during a routine investigation. Under the auspices of the Halle State Museum of Prehistory a systematic excavation was launched in 1971 that lasted until 1992 during which were documented and several human fossils were unearthed. Consequently administration of the site has been handed to the University of Jena.
In 1974 a piece of a human skull was identified among the finds. To date, 37 human bones and teeth have been found, mainly parts of the skull. They represent the remains of at least three individuals and have been classified as Homo erectus bilzingslebenensis by Emanuel Vlcek. The remains of the skulls show that they have been intentionally smashed postmortem, maybe as part of a burial rite.
Environment
Both plant impressions in the travertine and pollen remains allow the reconstruction of the local environment. There are two deposition phases. Both are dominated by woodland species. The first phase is dominated by hazel, ash and oak. The second phase is dominated by hornbeam, alder and pine. 36 plant species are attested by impressions in the travertine, among them 14 tree and shrub species:
The woods were mainly made up of oaks and box. Herbs like wormwood, sorrel, ferns and grasses attest the presence of open steppes or meadows. Sedges and rushes grew on the lakeshore, waterlilies and Sphagnummoss in the lakes. The remains of 54 species of animals have been found in Bilzingsleben, 35 species of mammals, six kinds of birds, three reptiles, three amphibians and five kinds of fishes. Among the mammals are:
Woodland animals predominate, but there are some species that prefer more open habitats as well, like rhinoceros, horse and bison. Mollusks attest to a climate that was warmer and wetter than today. The average annual temperature is supposed to have been 9° to 13°C, the annual precipitation 800 mm.
Important finds
The lithic industry is characterized by chopping tools of diminutive sizes. There are no true hand axes. The raw material is mainly flint, although quartzite, quartz and travertine have been used as well. There are numerous bone tools. Some hoes are made of antler or ivory. Even wooden artefacts have been preserved. One bone fragment, an elephanttibia, 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. The tibia dates to between 350,000 and 400,000 years ago. The interpretation as an early calendar is a possibility.
Structures
D. Mania found large stones arranged in a circular manner. He thought that it probably was a base for a dwelling. However, ring-center analysis showed that the site was an open air site. C. Gamble proposed that humans congregated at the site around the fire.
