Human occupation continuity in southern Italy towards the end of the Middle Palaeolithic: a palaeoenvironmental perspective from Apulia.

ABSTRACT: After the last interglacial [Marine Isotope Stage (MIS) 5e] Europe was affected by several harsh climatic oscillations. In this context southern Italy acted, like the rest of peninsular Mediterranean Europe, as a 'glacial refugium', allowing the survival of various species, and was involved in the spread of 'cold taxa' (e.g. woolly mammoth and woolly rhino) only during the coldest phases (MIS 4 and MIS 2). Both late Mousterian and early Upper Palaeolithic sites testify to a human occupation continuity in southern Italy and especially in Apulia in this time span. Here we present a focus on three key Apulian Palaeolithic sequences (Grotta di Santa Croce, Riparo L'Oscurusciuto and Grotta del Cavallo - layers F-E) jointly spanning from the late MIS 4 to the demise of Neanderthals around 43 ka. Novel chronological, sedimentological and zooarchaeological data are discussed for the first time in the light of the palaeoenvironmental information provided by recent analyses carried out on a speleothem from Pozzo Cucù cave (Bari) and the results of the magnetic susceptibility analysis from Riparo L'Oscurusciuto. This integrated reading allows a better understanding of the role played by the Apulian region as both a refugium for late Neaderthals and a suitable habitat for the early settling of modern humans.

Project description:In the Early to Middle Miocene, a series of lakes, collectively termed the Dinaride Lake System (DLS), spread out across the north-western part of the Dinaride-Anatolian continental block. Its deposits, preserved in numerous intra-montane basins, allow a glimpse into the palaeoenvironmental, palaeobiogeographic and geodynamic evolution of the region. Lake Gacko, situated in southern Bosnia and Herzegovina, is one of the constituent lakes of the DLS, and its deposits are excellently exposed in the Gračanica open-cast coal-mine. A detailed study of the sedimentary succession that addresses facies, sediment petrography, geophysical properties, and fossil mollusc palaeoecology reveals repetitive changes in lake level. These are interpreted to reflect changes in the regional water budget. First-order chronologic constraints arise from the integration of radio-isotopic and palaeomagnetic data. (40)Ar/(39)Ar measurements on feldspar crystals from a tephra bed in the upper part of the sedimentary succession indicate a 15.31 ± 0.16 Ma age for this level. The reversed magnetic polarity signal that characterises the larger part of the investigated section correlates to chron C5Br of the Astronomically Tuned Neogene Timescale. Guided by these chronologic data and a detailed cyclostratigraphic analysis, the observed variations in lake-level, evident as two ~ 40-m and seven ~ 10-m scale transgression-regression cycles, are tuned to ~ 400-kyr and ~ 100-kyr eccentricity cycles. From the tuning, it can be inferred that the sediments in the Gacko Basin accumulated between ~ 15.8 and ~ 15.2 Ma. The economically valuable lignite accumulations in the lower part of the succession are interpreted to indicate the development of swamp forests in conjunction with lake-level falls corresponding to ~ 100-kyr eccentricity minima. Pedogenesis, rhizoliths and palustrine carbonate breccias in the upper part of the section reveal long-term aridity coinciding with a ~ 400-kyr eccentricity minimum. Eccentricity maxima are interpreted to trigger lake-level high-stands. These are accompanied by eutrophication events caused by enhanced denudation of the surrounding basement and increased detrital input into the basin. The presented age model proves that Lake Gacko arose during the Middle Miocene Climatic Optimum and that the optimum climatic conditions triggered the formation of this long-lived lake.
