The wooden artifacts from Schöningen's Spear Horizon and their place in human evolution.

Ethnographic records show that wooden tools played a pivotal role in the daily lives of hunter-gatherers including food procurement tools used in hunting (e.g., spears, throwing sticks) and gathering (e.g. digging sticks, bark peelers), as well as, domestic tools (e.g., handles, vessels). However, wood rarely survives in the archeological record, especially in Pleistocene contexts and knowledge of prehistoric hunter-gatherer lifeways is strongly biased by the survivorship of more resilient materials such as lithics and bones. Consequently, very few Paleolithic sites have produced wooden artifacts and among them, the site of Schöningen stands out due to its number and variety of wooden tools. The recovery of complete wooden spears and throwing sticks at this 300,000-y-old site (MIS 9) led to a paradigm shift in the hunter vs. scavenger debate. For the first time and almost 30 y after their discovery, this study introduces the complete wooden assemblage from Schöningen 13 II-4 known as the Spear Horizon. In total, 187 wooden artifacts could be identified from the Spear Horizon demonstrating a broad spectrum of wood-working techniques, including the splitting technique. A minimum of 20 hunting weapons is now recognized and two newly identified artifact types comprise 35 tools made on split woods, which were likely used in domestic activities. Schöningen 13 II-4 represents the largest Pleistocene wooden artifact assemblage worldwide and demonstrates the key role woodworking had in human evolution. Finally, our results considerably change the interpretation of the Pleistocene lakeshore site of Schöningen.

A double-pointed wooden throwing stick from Schöningen, Germany: Results and new insights from a multianalytical study.

The site of Schöningen (Germany), dated to ca. 300,000 years ago, yielded the earliest large-scale record of humanly-made wooden tools. These include wooden spears and shorter double-pointed sticks, discovered in association with herbivores that were hunted and butchered along a lakeshore. Wooden tools have not been systematically analysed to the same standard as other Palaeolithic technologies, such as lithic or bone tools. Our multianalytical study includes micro-CT scanning, 3-dimensional microscopy, and Fourier transform infrared spectroscopy, supporting a systematic technological and taphonomic analysis, thus setting a new standard for wooden tool analysis. In illustrating the biography of one of Schöningen's double-pointed sticks, we demonstrate new human behaviours for this time period, including sophisticated woodworking techniques. The hominins selected a spruce branch which they then debarked and shaped into an aerodynamic and ergonomic tool. They likely seasoned the wood to avoid cracking and warping. After a long period of use, it was probably lost while hunting, and was then rapidly buried in mud. Taphonomic alterations include damage from trampling, fungal attack, root damage and compression. Through our detailed analysis we show that Middle Pleistocene humans had a rich awareness of raw material properties, and possessed sophisticated woodworking skills. Alongside new detailed morphometrics of the object, an ethnographic review supports a primary function as a throwing stick for hunting, indicating potential hunting strategies and social contexts including for communal hunts involving children. The Schöningen throwing sticks may have been used to strategically disadvantage larger ungulates, potentially from distances of up to 30 metres. They also demonstrate that the hominins were technologically capable of capturing smaller fast prey and avian fauna, a behaviour evidenced at contemporaneous Middle Pleistocene archaeological sites.

A 51,000-year-old engraved bone reveals Neanderthals' capacity for symbolic behaviour.

While there is substantial evidence for art and symbolic behaviour in early Homo sapiens across Africa and Eurasia, similar evidence connected to Neanderthals is sparse and often contested in scientific debates. Each new discovery is thus crucial for our understanding of Neanderthals' cognitive capacity. Here we report on the discovery of an at least 51,000-year-old engraved giant deer phalanx found at the former cave entrance of Einhornhöhle, northern Germany. The find comes from an apparent Middle Palaeolithic context that is linked to Neanderthals. The engraved bone demonstrates that conceptual imagination, as a prerequisite to compose individual lines into a coherent design, was present in Neanderthals. Therefore, Neanderthal's awareness of symbolic meaning is very likely. Our findings show that Neanderthals were capable of creating symbolic expressions before H. sapiens arrived in Central Europe.

Excavations at Schöningen and paradigm shifts in human evolution.

The exceptional preservation at Schöningen together with a mixture of perseverance, hard work, and sheer luck led to the recovery of unique finds in an exceptional context. The 1995 discovery of numerous wooden artifacts, most notably at least 10 carefully made spears together with the skeletons of at least 20 to 25 butchered horses, brought the debate about hunting versus scavenging among late archaic hominins and analogous arguments about the purportedly primitive behavior of Homo heidelbergensis and Neanderthals to an end. Work under H. Thieme's lead from 1992 to 2008 and results from the current team since 2008 demonstrate that late H. heidelbergensis or early Neanderthals used sophisticated artifacts made from floral and faunal materials, in addition to lithic artifacts more typically recovered at Lower Paleolithic sites. The finds from the famous Horse Butchery Site and two dozen other archaeological horizons from the edges of the open-cast mine at Schöningen provide many new insights into the technology and behavioral patterns of hominins about 300 ka BP during MIS 9 on the Northern European Plain. An analysis of the finds from Schöningen and their contexts shows that the inhabitants of the site were skilled hunters at the top of the food chain and exhibited a high level of planning depth. These hominins had command of effective means of communication about the here and now, and the past and the future, that allowed them to repeatedly execute well-coordinated and successful group activities that likely culminated in a division of labor and social and economic patterns radically different from those of all non-human primates. The unique preservation and high quality excavations have led to a major paradigm shift or "Schöningen Effect" that changed our views of human evolution during the late Lower Paleolithic. In this respect, we can view the behaviors documented at Schöningen as a plausible baseline for the behavioral sophistication of archaic hominins of the late Middle Pleistocene and subsequent periods.

The Spear Horizon: First spatial analysis of the Schöningen site 13 II-4.

The Spear Horizon (Schöningen 13 II-4) from Schöningen, Lower Saxony, Germany, is one of the most important archeological sites dating to the Middle Pleistocene. Until today, the numerous finds have only been published individually, often outside of their context. Here we present for the first time the distribution map of the Spear Horizon together with a spatial analysis of the different categories of remains (flint, bones, and woods). The finds are situated in a 10 m wide belt, which runs parallel to a former lakeshore. The distribution of faunal remains correlates closely with the distribution of flint artifacts and wooden objects. We have been able to distinguish five different sectors that can be aligned with different events or activities. The greatest density of finds was evident within an area of 11 × 15 m, where most of the horse skulls were recovered. Some of the square meters contain more than 150 finds. During the excavation the profiles were continually documented and these data help us to reconstruct the shoreline of the paleo-lake with considerable accuracy. Over a distance of 60 m, the thickness and density of the organic mud and peat layers could be reconstructed in high resolution. The distribution of finds shows no preferred orientation or selection through size. The analyses only indicate small-scale dislocations and limited taphonomic alterations. The fraction of lithic artifacts with size ranges less than 2 cm are preserved, while some smaller bone fragments are missing. Most of the wooden artifacts are in-situ, but were deformed by the ice load during the Saalian ice age. While some small charcoal remains as well as a burnt artifact have been observed, there is no evidence of burnt bones. Our results allow a first insight into the formation history of the site.

Overview and new results from large-scale excavations in Schöningen.

Archaeological finds including spears, other wooden artifacts, lithic artifacts, and bones with impact scars and cut marks document the repeated presence of hominins on the shoreline of an approximately 300,000 year old lake near Schöningen in Northern Germany. Continuing excavations have uncovered in the locality "Schöningen" at least 20 sites dating to the late Lower Paleolithic. Schöningen is therefore not only a singular archaeological site with remarkable finds; it is a vast locality that preserves a multifaceted archaeological landscape with numerous sites. Ongoing excavations have exposed several large surfaces with organic materials dating to MIS 9. In particular, recent excavations have uncovered new sections belonging to the original Spear Horizon from Schöningen 13 II-4 (the Horse Butchery Site). Current research in Schöningen places the exceptional artifacts within a spatial and environmental context, and provides a wealth of new information on the subsistence strategies and settlement dynamics of the inhabitants of these short-term lakeside occupations. Schöningen, with an overall excavated area of 9400 m(2), is one of the largest excavated archaeological localities from MIS 9. Here we present a summary of all the sites, as well as the most relevant excavated areas since 2008 (excavations Tübingen/NLD).

New insights on the wooden weapons from the Paleolithic site of Schöningen.

The Paleolithic site of Schöningen is famous for the earliest known, completely preserved wooden weapons. Here we present recent results of an ongoing analysis of the nine spears, one lance, a double pointed stick, and a burnt stick dating to the Holsteinian, c. 300 kyr. Macroscopic and microscopic analyses, as well as studies of thin sections, contribute to a better understanding of the manufacture of the wooden weapons. They were deposited in organic sediments at a former lakeshore among numerous bones of butchered horses. In general, the spears are extremely well-preserved and show no or little sign of taphonomic alteration, although some of the weapons are broken and parts were slightly moved, probably by water action. The excellent preservation conditions provide considerable information on the operational sequence of production. The hunters selected thin trunks of spruce or pine and initially stripped off the bark. Traces of cutting, scraping, and smoothing can be observed on the spear surfaces in detail. In the case of spear X, repeated use of the weapon is implied by re-sharpening of the tip. Analyses of wood anatomy provide information on climatic conditions and contribute to the better understanding of the development of the site.

The Middle Pleistocene tunnel valley at Schöningen as a Paleolithic archive.

Schöningen represents one of the key sites for Lower Paleolithic archaeology in central Europe, where a Middle to Late Pleistocene sedimentary succession, locally up to 45 m thick, has been preserved in an Elsterian tunnel valley. After deglaciation, the tunnel valley remained underfilled and provided the accommodation space for Holsteinian interglacial deposition and also kept the artifact-bearing strata below base level for subsequent erosion. The Holsteinian (MIS 9) succession consists of laterally and vertically stacked lacustrine delta systems, which were controlled by repeated lake-level changes. In the face of changing climatic and environmental conditions the long-lived interglacial lake provided an attractive site for animals and early humans. Artifacts were deposited on the subaerial delta plain and became embedded during lake-level rise. Although the area was considerably affected by erosion and glacitectonic deformation during the subsequent Saalian glaciation, the artifact-bearing Holsteinian strata were preserved in the deeper part of the tunnel valley. Tunnel valleys should be regarded as potential archives for interglacial deposits, which may contain important Paleolithic sites. Tunnel valleys may provide accommodation space and also have a high preservation potential. Interglacial lakes situated within underfilled tunnel valleys represented attractive sites for animals and early human hunter-gatherers.
