Although preservation of Paleolithic faunal assemblages from open-air settings is often poor, the Lower Paleolithic sites of Schöningen provide exceptionally well-preserved mammalian faunal material for investigating hominin/animal relationships. Pleistocene fossil assemblages, however, usually reflect a complex taphonomic history in which natural and anthropogenic processes are often superimposed. A number of examples of osseous finds that resemble tools were recently discovered in the MIS 9 deposits of Schöningen 12 II. Non-anthropogenic agents are known to produce surface modifications mimicking human artifacts and the identification of osseous remains used and/or deliberately modified by ancient hominins is often controversial in such old contexts. Multiple lines of evidence are thus useful for distinguishing between osseous artifacts and "eco-facts". In this paper, the recognition of the use of bone for different technological purposes by late Middle Pleistocene hominins is addressed through a multi-proxy study combining geoarcheology, bone taphonomy, zooarcheology, and use-wear analysis. This allowed the identification of the processes and agents responsible for the formation and modification of the different bone assemblages of Schöningen 12 II. Our analysis points to different types of bones having been likely used as tools. These results expand the diversity of the organic technological repertoire of the Middle Pleistocene hominins, making Schöningen 12 II a remarkable new source of information on osseous technology long before the Upper Paleolithic, the period traditionally viewed as the start of the systematic use of bone tools. Together with other observations of bone tools documented during the Lower and Middle Paleolithic, the results from Schöningen show that archeologists may have underestimated the diversity and importance of osseous technology among archaic hominins., (Copyright © 2015 Elsevier Ltd.

Within the various archaeological horizons in Schöningen, the presence of hominins is repeatedly demonstrated by the recovery of stone artifacts, broken bones, and bones with cut marks. The Spear Horizon, 13 II-4, with its ca. 1500 stone artifacts and ca. 12,000 faunal remains, represents by far the richest archaeological layers in Schöningen. Systematic waterscreening over a period of 15 years has fostered the recovery of numerous small flakes that otherwise would have remained undetected. Based on the stone artifacts published by H. Thieme and the lithic artifacts recovered from the ongoing excavations of the University of Tübingen and the Archaeological Heritage Office of Lower Saxony since 2008, we present here the main aspects of these lithic assemblages. The main features of the lithic assemblages recovered from the different find horizons and concentrations provide a consistent signature, suggesting a robust and repetitive technological strategy. The assemblages, which are made of local, high quality flint, lack handaxes and are clearly not related to the Acheulean. Intensely retouched scrapers, as well as denticulates, notched pieces, and points on thick flakes, angular debris, and non-anthropogenic thermal spalls are the most numerous retouched forms. The assemblages also contain a smaller number of thinner forms. Reduction sequences are short and Levallois technology is absent. Although some of the retouched forms are reminiscent of the Middle Paleolithic, the relatively non-standardized short reduction sequences technically oriented toward the production of thick and broad flakes are consistent with a classification in the late Lower Paleolithic., (Copyright © 2015.
