Using a database of 499 archaeological assemblages from 332 sites in Europe, we statistically test a model of the economic reactivity of the hunter-gatherer production system to climatic variations. This model predicts an increase in the diversity of lithic tools during harsh cold periods, in order to maintain carrying capacity, and a reduction during favorable climatic periods. Diversity was m...

In this paper we examine ways to predict the distribution of siliceous rock in Europe, using a Bayesian technique known as ‘Weights-of-Evidence’. We use the technique to classify bedrock geological formations in terms of their likelihood of yielding tool-quality lithic raw materials, and we use the results to reexamine possible causes of a west–east cline in maximum lithic raw material transfer...

Solutrean culture has been interpreted as a response to the Last Glacial Maximum in western Europe. However, to establish a link depends of our knowledge of the impact of global climatic changes at a local level and of the differential preservation and significance of the record. The identification of lithic sources, technology, function, and place of discard, is an effective way to mitigate so...

Introduction: Lunar meteorite Dhofar 961, a complex, lithic-clast-rich impact breccia [1,2], was called out by [3-6] as a candidate for an origin in the South Pole – Aitken (SPA) Basin region of the Moon (the SPA Terrane) on the basis of its relatively mafic, but nonmare lithologic and major-element chemical composition. It also has an incompatible-element signature that differs from the KREEP-...

The later Pleistocene archaeological record of southernmost Africa encompasses several Middle Stone Age industries and the transition to the Later Stone Age. Through this period various signs of complex human behaviour appear episodically, including elaborate lithic technologies, osseous technologies, ornaments, motifs and abstract designs. Here we explore the regional archaeological record usi...

The Palaeolithic sequence from Sodmein Cave in the Egyptian Eastern Desert, near Quseir, contains seven stratified archaeological levels from the Middle and Upper Palaeolithic. The lowest archaeological level (Middle Palaeolithic level 5) consists of huge fireplaces associated with a lithic assemblage in which Nubian Levallois technology and bifacial tools are present. From this level, six frag...

Endometrial carcinoma is the most frequent genital tract malignancy. The first symptom (guidesymptom) is usually metrorrhagia; however, in around 10% of cases it is not. In contrast, osseous metastases are infrequent in endometrial cancer. The bones of the pelvis and lower extremities are those most frequently involved in disseminated metastatic diseases. In these cases, endometrial cancer is u...

In the second half of the 19th century Pleistocene faunas were discovered in two sites, Sedia del Diavolo and Monte delle Gioie, contained in deposits of the Aniene River in the area of Rome (Latium, Italy). Fieldwork by A.C. Blanc in the late 1930's proved the association of fauna and lithic industry within fluvial deposits interbedded with volcanoclastic layers. A human femoral diaphysis and ...

Recent research suggests that variation exists among and between Oldowan stone tool assemblages. Oldowan variation might represent differential constraints on raw materials used to produce these stone implements. Alternatively, variation among Oldowan assemblages could represent different methods that Oldowan producing hominins utilized to produce these lithic implements. Identifying differenti...
