Application of 3D shape descriptors for the comparative study of blade assemblages – A case

study from the Upper Paleolithic of Western Syria

The description of the morphology of lithic debitage is a fundamental part of the analysis of lithic assem-

blages. Regarding lithic blades, longitudinal convexity, twist and the shape of the lateral edges are important

morpho-technological characteristics. In the past, researchers have recorded these morpho-technological

characteristics as qualitative attributes, because they are not readily quantiable. Here we present a quantita-

tive approach for the description of these characteristics by using 3D models of lithic blades. Our approach

combines two methods: 1) multivariate analysis of Elliptic Fourier coefcients deduced from 3D outlines

of blades, and 2) estimating curvature and torsion as geometric properties of a space curve tted to the

ventral surfaces of blades.

We apply the quantitative approach to the comparative study of Upper Paleolithic blade assemblages from

the stratied sites Baaz Rockshelter and Jaburd II in Western Syria. Our results indicate a non-directional

pattern of change in the shapes of blades and point to discontinuities in the production of specic forms

during the Upper Paleolithic. Comparisons between the shapes of blades from Baaz Rockshelter (layers VII

and V) and Yabrud II (layers 5 to 1) reveal that the characteristics of the analyzed assemblages from Baaz

Rockshelter nd no direct equivalents in Yabrud II. This observation points to potential differences in the

cultural background of the populations occupying both sites.

Although we are only now beginning to use quantitative approaches to characterize the shape of lithic arti-

facts, our results demonstrate that kind quantication of lithic assemblages bears great potential for the

study of morphological variability.

Environment and game exploitation in the east of the Aquitaine basin during late Upper Palaeo-

lithic: information from the natural trap of the Igue du Gral (Sauliac-sur-Célé, Lot, France)

Southwest France is a region with a particularly high density of Middle and Upper Palaeolithic sites. The

occupation of the Quercy region by modern humans began in the Late Upper Palaeolithic but remained

sparse compared with the Perigord at the same time. Hunting strategies concentrated on small ungulates like

reindeer or chamois. Until recently, this kind of prey spectrum was thought to indicate a scarcity of large

ungulates.

Research on natural traps in this region carried out in the last 10 years allows a new interpretation of human

choices. The natural trap of the Igue du Gral contains very rich and well preserved paleontological assem-

blages. Unusually for the region, there are several distinct horizontal strata inducted by different opening/
