The Neanderthals of Okladnikov Cave Altai: Environment and Diet Based on Isotopic Analysis*

The discovery of a Mousteroid industry in the northwestern Altai represents a major finding in Eurasian Paleolithic studies. Isotopic analyses of bone collagen of late Western European Neanderthals have repeatedly indicated that they were extremely carnivorous. However, no corresponding information was previously available for the Neanderthals of the Altai. With this in mind, an isotopic study was conducted to assess the diet of the Middle Paleolithic inhabitants of Okladnikov Cave. Collagen was extracted from seven well preserved bone samples of adults and children and 13С/12С and 15N/14N ratios were calculated. The δ13С content suggests that all individuals were members of a local trophic chain based on plants of the moderate climatic zone. However, the δ15N content demonstrates that their trophic level was high. These findings suggest that the lifestyle of Neanderthals in the northwestern Altai was similar to that of the late European Neanderthals. Both evidently subsisted by hunting large herbivores.     

Earliest hunters and gatherers of South America

Traditional syntheses of the archaeology of the late Pleistocene period in South America have focused primarily on the peopling of the continent by North American cultural groups and on identifying associations among regional sites. This focus has tended to ignore the widespread culture diversity of the period and the possible effects of different paleolandscapes on human migration and colonization, such as the presence of unglaciated tropical and temperate environments in the northern lowlands, the gateway to the interior. The earliest known cultural assemblages are characterized by various unifacial and bifacial lithic industries that may represent regional processes reminiscent of an Archaic lifeway. The major archaeological sites and associated artifact assemblages are examined in terms of regional and continental patterns of environmental and cultural change. Results suggest that the Pleistocene archaeological record of South America must be explained in its own terms and that the events and processes producing this record either occurred earlier than previously thought or are very different from those in North America.
