Human settlement of Italy during the Younger Dryas
No full textA thorough review of the evidence of human settlement in Italy during the Younger Dryas (YD) is presented, making use of 14C-dated sites and, in some instances, of sites dated by proxy indicators (lithic seriation, cold-adapted animal species). Calibrated dates within the range 12.9-11.6 ka BP are retained. The analysis is arranged following a geographical division between northern Italy, with the pre-Alps and the north-eastern slope of the Apennine, and south-central Italy, with Sicily. In total, 31 dated sites are included, some of which multi-layered. The elusive evidence from Sardinia is also briefly discussed. It is underlined that there are far more cave sites than open-air sites in this sample, mostly because archaeological research has focused on caves, while taphonomy explains the partial destruction of the record in the open. A wide range of environments was settled, from coastal areas to river valleys, from lake basins and high plateaux to mountain ranges up to c. 1500 m asl. The most frequently hunted animals were either ibex (mountains as well as rocky cliffs, even at sea level and in the South), or hydruntine horse (plains and hills), accompanied by red deer. Birds, molluscs, and fish were also important resources at some sites. Rituals are indicated by a number of formal burials, while artwork includes Azilian pebbles and geometric wall engravings. In the pre-Alps, there are changes in the settlement pattern as campsites were smaller and shorter-lived than during the Alleröd. However, the same mountains and high elevation hunting grounds were exploited in the YD as before, and Alpine passes were crossed. Elsewhere, all over peninsular Italy, cave sites were in use again and again. Even if the climate was worsening, with temperatures markedly lower than during the Alleröd, the general conclusions are that, in the case of Italy, at the YD some limited indicators of stress can be detected so far only in Alpine areas
MORPHOMETRIC ANALYSIS TO EXPLORE THE SURROUNDINGS OF THE MELKA KUNTURE PREHISTORIC SITE
No full textThe area of Melka Kunture (central Ethiopia) is one of
the most important clusters of Paleolithic sites in Eastern
Africa. The archaeological record spans from ca. 1.7 Ma
onwards, with a number of stratified occurrences of Oldowan,
Acheulean, Middle Stone Age and Late Stone Age
industries, together with faunal remains and human fossils.
However, the archaeological sites are affected by present
day processes. These processes are mainly triggered by the
climatic conditions and specific Paleo-landscape forms
and features in the nearer surroundings of Melka Kunture
and the upper Awash catchment. Hence, the main aims
and objectives of this study are the assessment of the present
day geomorphological and hydrological processes as
well as the detection of Paleo-landscape pattern.
Based on fieldwork, aerial photo interpretation and a detailed
DEM analysis we derived a geomorphological map
of the Melka Kunture area. Furthermore, we assessed the
major landscape forming process using physically based
models and a detailed Terrain Analysis. For this study
we utilized the SRTM-X with 25m resolution and ALOS/
PRISM DEM with 10m resolution.The study reveals the spatial distribution of present day
landscape forming processes. Especially surface runoff
and soil erosion processes were analysed in detail. Moreover,
we identified evidences for specific Paleo-landscape
pattern in the surroundings of Melka Kunture. In
part these features can be explained with tectonic activity,
on the other hand they indicate specific pattern of
the Paleo-drainage network
