1. Introduction

The study of archaeological objects relies at its very base (and though at any higher level of inference) on criteria and variables chosen to systematise and categorise the record. Typologies have frequently been used in Paleolithic research on stone tools (Bordes 1961; 1967; Laplace 1962; 1972; Sonneville-Bordes and Perrot 1954). Notwithstanding their success, they were frequently questioned and discussed (e.g. Semonov 1970). Two methodological problems became apparent almost from their initial introduction into alaeolithic research rstly the inconsistent selection o de ning variables and secondly their vulnerability to subjectivity during analysis. These aspects still play an important role in current discussions (see for example Aubry et al. 2008 and contributions therein; Schmidt and Mom 2012; Shott 2003) and shall be addressed in the following by two case studies conducted on lithic tools deriving from the Solutrean technocomplex of the Iberian Peninsula.

2. Solutrean Points and Typological Classification

The Solutrean technocomplex occurs in south-western France and Iberia and lasts from about 25 to 19 ky cal BP (calibrated before present). It was originally de ned by the presence o invasively shaped artefacts, summarised as ‘Solutrean points’, which were produced using pressure retouch or soft-hammer direct percussion to shape one or both surfaces. Being distinct from artefacts occurring in the earlier (Gravettian) and subsequent (Badegoulian, Magdalenian) technocomplexes,

olutrean points ere used as inde ossils to de ne and internally subdivide the cultural succession of the Solutrean (Smith 1966). Spatially and temporally restricted occurrences of several Solutrean point types are recorded during the Upper Solutrean (Banks 2009; Jordá Cerdá 1955; Soler 1986; Straus 1983; Zilhao 1997).

Some of these well-established point types are of similar or equal shape, but are conventionally

Abstract:This paper presents results of a shape analysis conducted on lithic Solutrean points from the Iberian Peninsula. By using SECANTO, a computer application especially designed for this purpose, the variability of shapes between and within selected Solutrean point types is explored and discussed. Shape has always been considered an important variable in the analysis of prehistoric lithic Solutrean points, namely in typologicalapproaches. o e er, esides eingrarelyo jecti edand uanti a lymeasured,littleefforthas eenmadetounderstandinterrelation et eenmorphologyandtechni uesappliedduringproductionprocesses,ortheeffectso use li eonthearte acts shape.Thestudyin estigatestheseinterrelationsanddemonstratesthepotentialo ano jecti edcomputationalapproacho shapeanalysis.Theanalysiscanbe used to identify and explore methodological problems in existing typologies as well as to set up new models on shape variability in lithic tools.

distinguished because o different technological strategies applied during production. In the following case studies, we concentrate on these speci c types. hey directly allo investigating relations between shape and technological organisation of tool production and use, as well as spatial distribution. Morphometric studies often ignore effects o technological choices during production and use-life of tools, but we argue that this interplay must be considered a key concern in morphometric analysis in general (Schmidt and Mom 2012). Morphometric studies which do not consider the processes of production, function, and use will hardly be able to pose and answer relevant questions to the prehistoric records.

3. Materials and Methods

3.1 Studied material

Data presented in this study were obtained within the framework of a techno-functional analysis of almost 1500 Solutrean points – including preforms and fragments – deriving from 63 Spanish and Portuguese sites. The sample comprises about ell preserved and nearly nished specimens, attributed to Upper Solutrean contexts. Out of this database, four point types were selected for the present study. Classically they are referred to as unifacial points, Laurel Leaf points, ‘Franco-Cantabrian shouldered points’ and ‘Mediterranean’ shouldered points. In total, the subsample comprises 231 specimens.

The common distinction between ‘unifacial points’ and bifacial ‘Laurel Leaf’ points (cf. Sonneville-Bordes and Perrot 1954) proved to be of chronological signi cance or the Early to iddle Solutrean context in France and Iberia (Smith 1966;

Zilhao 1997). However, within the Iberian Upper Solutrean context, this technological dichotomy already proved to be irrelevant for several point types e.g. tanged and inged points iffagom 2006; concave based points, Schmidt 2013), but remained uncontested so far in the case of leaf-shaped points.

Shouldered points from the Iberian Solutrean are generally distinguished into two types, the Franco-Cantabrian and the Mediterranean shouldered points (Fortea Pérez and Jordá Cerdá 1976; Jordá Cerdá 1955), which, as the names suggest, did show distinct spatial distributions (see below). To avoid these geographical names, they will be referred to as shaped shouldered points (‘Franco-cantabrian shouldered points’) and abrupt retouched shouldered points (‘Mediterranean shouldered points’).

3.2 Comparing shapes using SECANTO

The use of computer programs improves ob ectivity e ciency and reproducibility in the area of shape analysis considerably. We used the computer program E om Schmidt and Mom 2012) to objectify and quantify the differences in shape bet een each analysed specimen. Fig. 1 shows how the ‘shape distance‘ between two points is measured.

The two points are scaled along the vertical a is to e ual height. ubse uently the differences (distances) between the outer boundaries of the two projected shapes are measured. Both the left side and the right side of the shapes contribute 150 values. he differences are s uared and summed after which the square root of the sum is taken. The value o the resulting uanti er is a measure or

the difference in shape bet een the t o points c . Schmidt and Mom 2012).

Repeating this calculation for all pairs of points in the data set, results in a symmetric distance matrix with values of zeros along the diagonal axis. This distance matrix is the basis for subsequent statistical analyses of the data set.

3.3 Explorative statistics

ifferent statistical methods can be used or the exploratory analysis of the distance matrix. For our purpose, we use the Principal Coordinate Analysis (PCoA), also known as metric multidimensional scaling (MDS). The calculations were done with the free statistical package PAST (Hammer, Harper and Ryan 2001).

The PCoA positions the objects within a space o reduced dimensionality based on the E distance values. The eigenvalues (“importance of a given dimension in accounting for variation in inter-point distances”, Shennan 2004, 347) and percentages (“percentage of the inter-point distance in the data accounted for by that dimension”, ibid.) are provided for the 1st and 2nd principal coordinate. For interpretation of the two-dimensional scatter plot, it is necessary to re-examine the structuring factors of the distribution, as calculation in this case starts from a single distance value, not from several variables de ning each specimen. o do so the distribution has to be checked against morphological characteristics of the individual points.

4. Case Studies

To test and evaluate the exploratory potential o shape analysis using E e per ormed

two case-studies on lithic Solutrean points. These analyses demonstrate the ability and potential that lies in an ob ecti ed computational approach. t enables a working hypothesis about the reasons for different ranges and patterns o variability in shape.

4.1 First case study: shapes and technological strategies

he rst case study e plores the variability of shapes between all four classical Solutrean point types of the Iberian Peninsula introduced above: the shaped and the abrupt retouched shouldered point types, the unifacial points, and the bifacially shaped (Laurel Leaf) points, the latter two summarised subsequently as leaf-shaped points. The total sample consists of 231 specimens.

E amining the output o the o analysis o the E distance matri ig. sho s that the 1st coordinate captures variability of the length-width proportions, with broad and short specimens in the negative range (to the left) and elongated ones in the positive range (to the right). The 2nd coordinate displays variability of morphology and ratio between stem (shoulder) and point, and basal and terminal end, respectively. The main observations are:

• E discriminates bet een the t o morphological groups of shouldered points and leaf-shaped points, although morphological differences ithin these groups are greater than between them.

• verlap on the rst t o a es e ists or specimens with extremely short stems (shouldered points) or elongated and asymmetric shapes (leaf-shaped points).

• ased on shape alone no differentiation can be made between the unifacial points and Laurel Leaf points.

• ased on shape alone no differentiation can be made between the two technologically distinct types of shouldered points (shaped and abruptly retouched).

• difference in morphological variation e ists between shouldered and leaf-shaped points: the latter cover almost the same variability of shapes, while there is a distinct pattern among shouldered points.

• For leaf-shaped points, the results suggest that the distinction between unifacial points and Laurel Leaf points – which involves distinct technological strategies of blank production and modi cation has little effect on the nal shape in the Iberian Upper Solutrean context. It also indicates that possible resharpening processes similarly affected the morphology o both types, although short and broad specimen

ith short terminal ends most likely affected by resharpening) tend to be bifacially shaped points (Fig. 2, upper left area). Our working hypothesis based on the E analysis is that the two technological strategies were applied interchangeably to obtain identical morphological tools.

Contrarily, abrupt retouched and shaped shouldered points show distinct patterns: the

spectrum o shapes is much more de ned among abrupt retouched than among shaped shouldered points (Fig. 2). The former are in general more elongated and thin, with a tendency towards specimen with very short stems (shoulders) compared to the terminal (pointed) part. The latter show a greater heterogeneity which includes a number of points with very short pointed ends in relation to the size of their stems. Two hypotheses can be proposed based on the observations made on shouldered points. Firstly, technological strategies chosen during production do have an in uence on the extent of shape variability of the tools. Secondly, shaped shouldered points were probably more intensely resharpened than abrupt retouched ones.

However, other than in leaf-shaped points, the two technological types show regionally distinct distributions across the Iberian Peninsula. This leads us to the second case study that looks at the geographical variability of their shapes.

4.2 Second case study: shape, technology, and geographical distribution

For shouldered points, we would like to test hether the differences in shape variability represent geographical phenomena related to the technological strategy used during production.

The distribution of shaped shouldered points is mainly restricted to northern and western parts of the Iberian Peninsula, while abrupt retouched points occur dominantly in south-eastern and western Iberia, and are very rare in northern Iberia (Fig. 3). The area of overlap, where both types occur in comparable numbers (although generally few) is the western region, i.e. in Portugal (Aubry 2001; Bicho et al. 2003; Cascalheira 2010; Zilhao 1997).

n the rst step the sample as again discriminated by the technology o modi cations that is between shaped/partially shaped (n=79) and abruptly retouched (n=61) shouldered points (Fig. 4). In a second step, the sample is divided by three main regions; northern, south-eastern and western Iberia (Fig. 5).

Taking a closer look at the variability of shape or these t o technological point types the rst t o

principal coordinates of the PCoA (Fig. 4) capture

Spatial distribution of shaped and abrupt retouched shouldered points (n=369) taken from a database comprising specimen which are excluded from the present analysis of shapes (i.e. fragmented points). Pie-charts reflect ratio between the two types for each single site (n=41, not divided by single assemblages).

the following morphological characteristics: the 1st coordinate accounts again for the length/width ratio of the points, the ratio being in this visual output higher (elongated points) on the left (negative values) and lower (short and broad) at the right (positive values). The 2nd coordinate captures the ratio between length of stem and length of point (negative values = longer stems; positive values = longer points).

s stated above the E analysis indicates that shapes are signi cantly less variable among abrupt retouched shouldered points. Moreover, they tend to dominate the thin and elongated point morphologies. Shaped and partially shaped shouldered points of southern Spain and

ortugal obviously undergo different processes.

esharpening most likely affects the terminal part of these tools and therefore reduces the point/stem as well as the overall length/width ratio. It can

be expected that such specimens are sorted to the right of the scatter diagram (Fig. 4). Only shaped shouldered points occur here, indicating that they repeatedly underwent resharpening processes, contrary to abruptly retouched points.

Comparing this output to a now spatially coded PCoA of the same sample (Fig. 5), shouldered points in northern Iberia do cover even both, the left and right extreme of shape-variability on the 1st coordinate. Contrarily, variability is much less pronounced in western as well as in south-eastern Iberia. It appears that the shaped shouldered points of western Iberia are as standardised as the abruptly retouched ones in these areas, while morphologies of abrupt retouched shouldered points in northern Iberia are extremely heterogeneous.

Several hypotheses can be set up based on these observations to e plain the different patterns requiring analysis of raw material, blank selection,

point production, and use-life. Variability could emerge rom different availability o good uality ra material in the areas. Technologically, the material suggest that the selection of more standardised blanks during the process of manufacture of shouldered points in western and southern Iberia – be they shaped (west) or abruptly retouched (west and south-eastern) – led to more standardised morphologies. Also, points from northern Iberia underwent resharpening processes more frequently than those in other areas. Such longer use-life cycles could also account for the overall less frequent occurrence of shouldered points in northern Iberian sites.

5. Final Remarks

Our study demonstrates the potential for ob ecti ed computational approaches to the analysis of shapes. It shows that such data can be used to identify and subsequently explore problematic methodological issues in existing typological systems. Moreover, we hope we showed its usefulness as a tool to develop hypothesis on shape variability of lithic points. It stimulates research questions on technological organisation of prehistoric hunter gatherers, and provides insights into regional and temporal variability.
