A new method for the quantitative analysis of cutmark micromorphology

Cutmarks found on the fossilised bones of butchered animals provide direct evidence for the procurement of meat through technological means. As such, they hold some of the oldest available information on cognitive ability and behaviour in human evolution. Here we present a new method that allows a three-dimensional reconstruction of cutmark morphology and the quantification of profile parameters. We have tested this new technique on cutmarks that were experimentally inflicted on a pig rib using a steel knife and an un-retouched flint flake at different angles. The method allows for the cross-sectional shape, the sharpness and depths of the resulting cutmarks to be quantified. The data show that knife mark sections are characterised by a V-shape or √-shape depending on the inclination of the knife. Cutmarks produced with the flint flake were less clearly defined and generally less sharp than those produced by the knife. We discuss the method's potential to provide new information on butchery technique and cognitive abilities developed by the human lineage, from the earliest tool-using hominins through to modern Homo sapiens.     

Zooarchaeological Evidence for Domestic Rituals in the Iron Age Communities of North‐Eastern Iberia (Present‐Day Catalonia) (Sixth–Second Century BC)

Many socio‐economic changes occurred in southern Europe during the first millennium BC. In north‐eastern Iberia societies evolved from the small‐scale local groups of the Late Bronze Age to the more complex societies of the Iron Age. Together with a diversity of material changes (detected in pottery, agricultural techniques, architecture, etc.), a new ritual manifestation is attested in the Ancient Iberian Period (about 550 BC), lasting until some time after the Roman conquest. This consisted of sheep and goats (among other species) being carefully deposited below the floors of some domestic buildings. In this article the characteristics of these associated bone groups are described and their significance is discussed.     

Marble Pieces in the Romanesque Portal of Glory of the Santiago de Compostela Cathedral. New Data through a Multi-Analytical Approach

ABSTRACT

Probably the most important Romanesque artwork in Spain, the Portal of Glory of Santiago de Compostela is essentially made in granite, the most abundant stone in the NW of Iberia, with the only exception of five marble pieces. Different hypothesis on the origin of these marbles have previously been proposed based on visual assessment or by directly assuming a local source. To shed light on their quarry provenance, a multi-analytical study was performed combining polarized-light optical microscopy, cathodoluminescence microscopy, XRPD, SEM-EDS and stable C and O isotopes. The comparison of the results with the available databases reveals the use of marbles from the Estremoz Anticline (Portugal) in the three exquisitely carved columns strategically placed in the central arcade, whereas the other two pieces are local marbles, illustrating a more complex consumption of this noble material than that initially expected.
