This paper presents the results of excavations at an Upper Palaeolithic site that was discovered at Rookery Farm, Great Wilbraham, Cambridgeshire in 2002. Diagnostic lithic material – three penknife points – indicates that the site was probably occupied between 12,000 and 11,000 BP, a time of deteriorating climatic conditions. Excavations discovered a small task site, located to take advantage of water and a lithic raw material source. The paper discusses Rookery Farm in relation to other sites of this date and patterns of mobility and settlement across north-west Europe.

Lithic Raw Material

In terms of supply of good quality raw materials for stone tool manufacture, the area of southeastern Poland is rather poor. Considering research conducted so far, there are only few sites that can be the basis for analysis. Nevertheless, certain phenomena seem to be characteristic on sites in southeastern Poland in the later phase of the Upper Palaeolithic and in the Late Palaeolithic. There are usually more than one kind of raw material present. Apart from local erratic flint, imported Świeciechów (grey white-spotted) and ‘chocolate’ flint dominate. The presence of both Jurassic (areas near Cracow) and Volhynian flints are poorly recorded, whereas resources from the south are almost absent. These imported raw materials indicate the existence of particularly strong relations linking the areas of southeastern Poland with the Sandomierz Upland, and much weaker relationships with the territories of Lesser Poland and Western Ukraine

A study of the differential preservation of the famous Côa engravings, in the light of the site of Fariseu, place the distribution of the art in a chronological setting, which is in turn placed within the context of lithic raw material procurement.

Section Analysis

The present paper discusses the contribution of Micropaleontology and Biostratigraphy to the archaeological research using as a case study the Upper Palaeolithic cave of Kastritsa in the Ioannina basin, north-west Greece. Thin section analysis applied to a selected number of stone tools from the site suggested that raw materials employed in their manufacture could originate from the Ioannina basin or even from outcrops in the proximity of the cave. This suggest that once Palaeolithic groups arrived at the cave, they practised low mobility which in turn suggests that a range of subsistence opportunities were available in the area allowing to its inhabitants extensive stays. This hypothesis is well supported by the archaeological record of the site. Micropaleontology and Biostratigraphy can be a useful method in the investigation of raw material provenance, especially when sedimentary rocks are studied, and it can provide significant insights into huntergatherer mobility strategies.

AbstractMicrocrystalline cellulose (MCC) is a semi-crystalline material with inherent variable crystallinity due to raw material source and variable manufacturing conditions. MCC crystallinity variability can result in downstream process variability. The aim of this study was to develop models to determine MCC crystallinity index (%CI) from Raman spectra of 30 commercial batches using Raman probes with spot sizes of 100 µm (MR probe) and 6 mm (PhAT probe). A principal component analysis model separated Raman spectra of the same samples captured using the different probes. The %CI was determined using a previously reported univariate model based on the ratio of the peaks at 380 and 1096 cm−1. The univariate model was adjusted for each probe. The %CI was also predicted from spectral data from each probe using partial least squares regression models (where Raman spectra and univariate %CI were the dependent and independent variables, respectively). Both models showed adequate predictive power. For these models a general reference amorphous spectrum was proposed for each instrument. The development of the PLS model substantially reduced the analysis time as it eliminates the need for spectral deconvolution. A web application containing all the models was developed.

Previous morphometric studies have identified variation in fluted-point thickness data but have seldom considered its cultural or technological sources. New data from western and eastern North America suggest that variation in fluted-point thickness results from variability in lithic raw-material selectivity and bifacial-flaking techniques.
