REFITTING AT LAPA DO ANECRIAL: STUDYING TECHNOLOGY AND MICRO SCALE SPATIAL PATTERNING THROUGH LITHIC RECONSTRUCTIONS.
Lapa do Anecrial is a cave site located in central Portuguese
Estremadura. Three field seasons already completed have provided a stratigraphic
sequence spanning the transition from the Gravettian to the Solutrean in
Central Portugal. In layer 2 (Terminal Gravettian), the more extensively
excavated, excellent post-depositional conditions have preserved several
clusters of lithic artifacts and fauna, representing activities taking
place around a hearth. The refitting studies, already concluded, reaffirm
the excellent post-depositional preservation of the site: more than 51%
(92% by weight) of the lithic assemblage was refitted, making possible
an almost complete view of the reduction sequences and strategies used.
This paper presents the various advantages of the application
of refitting to the Lapa do Anecrial layer 2 assemblage: both for lithic
technology and spatial analysis. The main technological characteristics
of the studied assemblage will be described. The reconstructions show how
a carinated thick-nosed bladelet production strategy was often associated
(in the same block) with traditional prismatic bladelet technology. Such
association, which results in high core to cobble ratios, was detected
not only for flint, but also for quartz, a raw material usually considered
as having inferior knapping qualities.
The combination of the lithic reconstructions with the
tri-dimensional spatial patterning of the artifacts makes possible a first
attempt to interpret the micro-scale spatial organization of the short-term
occupation of Lapa do Anecrial, during Terminal Gravettian times.

REFITTING AND THE BRITISH LOWER PALAEOLITHIC: A CRITICAL REVIEW
Refitting is a well established but time-consuming and
costly method of analysis, and in the context of the British Lower Palaeolithic
has been criticised for telling us little about behaviour or cognition.
This paper reviews the British evidence and the role refitting has played
in enhancing our understanding of taphonomy, technology and behaviour.
It is argued: that for taphonomy it is a basic and essential tool of analysis
for assessing the integrity of assemblages; that for furthering our understanding
of technology, its real potential has sometimes not been realised; and
that for insights into behaviour, its real value lies in the recognition
of repeated patterns of movement. Despite the costs it must remain an important
tool for understanding fine-grained behavioural signatures.

REFITTING AND SPATIAL STRUCTURE AT THE ALLEN SITE
This paper discusses patterns of lithic refits and artifact
and feature distributions at the Allen site, a stratified Paleoindian camp
in Nebraska. Low refit frequencies within and between horizontally
discrete artifact concentrations suggest that these concentrations are
aggregates deposited as dumps during camp cleanup. The similar locations
of such concentrations throughout 2000 years of site occupation, and the
lack of evidence in the refits for vertical movement of artifacts, suggest
that old dumps were magnets for new ones. Variation in refit patterns
and in the relation between artifact and hearth frequencies in different
levels suggests a long-term trend towards more temporary, and perhaps less
frequent, site use that parallels trends in other aspects of the site assemblage.

DU BON USAGE DES REMONTAGES EN PRÉHISTOIRE? (INTÉRÊTS ET LIMITES) LE CAS DU GISEMENT MAGDALÉNIEN DE PINCEVENT.
Depuis près de 40 ans, le gisement magdalénien
de Pincevent fait l’objet de fouilles scrupuleuses et développées
tant au plan diachronique qu’au plan synchronique.
Claudine Karlin en 1964 lors de l’étude de l’habitation
n°1 avait lancé « la mode » et systématisé
ce qui devait devenir une véritable méthode d’étude
des séries lithiques. Un peu moins de 40 ans plus tard et 4500 m2
fouillés plus loin, nous avons pu appliquer cette méthode
au plus vaste sol d’occupation magdalénien du gisement de Pincevent,
le niveau IV20. Les premiers résultats de cette réflexion
avaient été présentés dans les actes du symposium
: « The Big Puzzle » en 1990.
Dans le cadre d’une thèse soutenue en 1994, il
nous a été donné de documenter plus encore les comportements
techniques mais aussi économiques et spatiaux d’un groupe de magdaléniens.
En réalisant un taux de remontages de plus de 90% sur le matériel
lithique provenant d’une zone du niveau IV20, nous avons en effet pu sérieusement
traiter des modalités techniques et économiques du débitage,
inscrire l’outillage au sein de son système de production mais également
discuter de l’organisation spatiale des activités concernant la
taille du silex et l’utilisation des produits obtenus. Quelques inférences
sur la composition du groupe ont également pu être avancées
s’inspirant des travaux de Nicole Pigeot menés à Etiolles
ou de ceux de Sylvie développés à Pincevent.
A travers quelques exemples pris dans cette étude
particulière, nous discuterons ici de l’intérêt de
la méthode des remontages mais également de ses limites fusse
t’elle appliquée à hauteur de 90 % d’une industrie lithique.

BENEFITING BY REFITTING AT LATE PALAEOLITHIC REKEM (BELGIUM)
The procedure of refitting is most benefited from when
fully embedded in an integrated research program. Refitting can then help
to entangle a wide variety of research topics also touched upon with other
approaches (petrography, attribute analysis, usewear, etc.). The late Palaeolithic
site of Rekem serves as a case study in this respect. The lithic material
from this large camp site offered excellent refitting potential (some 2500
artefacts conjoined so far), permitting a detailed study of reduction strategies
and spatial distributions. With regard to lithic technology, the refitting
data provided better insights into both flint reducing methods and knapping
styles as well as into the processes of tool manufacture, use, maintenance
and discard. Derived from these data, the method also informed on social
aspects (skills of the artisans) and economic features (the material ‘output’
of the various sequences and its role in further activities). On a spatial
scale the results of refitting could be used to measure the degree of vertical
dispersal and to assess the disturbance on the site by natural post-depositional
processes. Most importantly, however, the mapping of refits supplied important
insight into the horizontal patterning of human activities both in and
between the various loci of the site. At Rekem, such patterning shows the
relationship between manufacturing process and artefact discard and elucidates
the transport patterns of various kinds of artefacts and tool types.

L’APPORT DES REMONTAGES DANS L’APPROCHE DE LA COMPLEXITÉ TECHNIQUE ET ÉCONOMIQUE DES CHAÎNES OPÉRATOIRES DU PALÉOLITHIQUE MOYEN.
La complexité des chaînes opératoires
de production lithique au Paléolithique moyen est un phénomène
que l’on perçoit depuis un certain nombre d’années au travers
de pratiques telles que le débitage sur éclats. Grâce
à l’exploitation de l’information dynamique apportée par
l’étude d’ensembles remontés, on est désormais en
mesure de cerner les mécanismes et la logique technique d’une telle
complexité. Dans les deux gisements qui sont pris en exemple ici
(Le Pucheuil et Etoutteville, Haute-Normandie, France), les remontages
dévoilent l’existence de chaînes opératoires longues
et ramifiées, avec plusieurs objectifs techniques clairement hiérarchisés.
La chaîne opératoire principale fait appel dans les deux sites
aux principes du débitage Levallois, sur lequel repose l’essentiel
de l’investissement technique. Les chaînes opératoires secondaires
sont réalisées à partir des sous-produits de la chaîne
opératoire Levallois. A partir d’un même bloc de silex, 2
voire 3 principes de débitage ont été indépendamment
mis en œuvre, pour autant de types de produits obtenus. Le débitage
Levallois, généralement considéré comme très
dispendieux en matière première, serait-il au contraire dans
certains contextes l’un des champions toutes catégories de l’économie
de la matière première ?

SICKLE MANUFACTURE IN BRONZE AGE DENMARK – PUZZLING FLINTS FROM BJERRE.
This contribution presents the results of an ongoing research
project aiming at a contextual "chaîne opératoire" analysis
of Early Bronze Age flint sickle production technology. The lithic inventories
examined belongs to a cluster of seven settlement sites from Bjerre, situated
in the flint-rich region of Thy, Northern Jutland. The analyses presented
involve a reconstruction of core reduction sequences (through refitting)
as well as technological studies (through attribute analyses) aiming at
a dynamic reconstruction of primary production sequences. The following
discussion will assert the "chaîne opératoire", complexity
and completeness of assemblages, technological skills, and degree of specialization
in tool production (pressure flaked artifacts versus simple retouched tools)
as well as the resulting sociocultural and behavioral implications for
our interpretation of Early Bronze Age lithic technology.

AUSTRALIAN POINT AND CORE REDUCTION: A REFITTING CASE STUDY
Refitting of knapping floors in Queensland Australia is
used to analyze the production technology employed during the mid-late
Holocene. Examination of refits at quarries is the basis of a study not
only of the general sequence of reduction but also the solutions that knappers
apply to solve problems they encounter. A series of refitted knapping floors
at increasing distances from quarries reveals the progressive modification
of bifacial points and cores as material is transported through the landscape.
Some general principles are explicated.

THE HAMBURGIAN SITE AT OLDEHOLTWOLDE (NL): THE MULTIFACETED OUTPUT OF REFITTING
Refitting analysis of flint artefacts resulted in insights
concerning a multitude of aspects. Its most rewarding contribution is the
creation of dynamic pictures, e.g. showing movements of flint implements
from production centres to activity areas. In total, 850 flint artefacts
are involved in 179 refitgroups (containing up to about 100 artefacts).
The Hamburgian chaîne opératoire for blade production
could be reconstructed; the en éperon technique is not part
of it. Because of differences in knapping skill, revealed by larger
refitgroups, three flintknappers were identified: a master knapper (probably
an adult man), an advanced pupil (probably an older boy) and a totally
unskilled knapper (probably a young boy). Only a minority (about a quarter)
of the tools were manufactured at the site. The many imported tools include
all the points and most of the scrapers. Especially notched tools and ‘Zinken’
were made, used and discarded on the site. The final occupation phase saw
the production of many tools and blades that were taken away from the site.
By combining refitting results with ring and sector analysis, it can be
shown that the occupants probably rotated around the outdoors hearth, in
response to changes in wind direction.

TOWARDS AUTOMATED LITHIC REFITTING: DREAM OR REALITY?
The multidisciplinary “Partnership for Research in Stereo
Modeling” (PRISM) at Arizona State University conducts research on various
topics in 3D modeling. One of the pilot projects involves an attempt to
(partially) automate the lithic refitting process. Lithic refitting has
proven to be a tremendous tool for prehistorians to reconstruct lithic
technology, study taphonomy, and investigate spatial patterning. The drawback
to lithic refitting, as one of many lines of evidence drawn upon to study
the prehistoric past, is the enormous time investment it requires. Furthermore,
due to understandable limitations in the access to lithic collections imposed
by the various antiquities departments throughout the world, lithic refitting
is often left out of the research agenda altogether. These problems point
to a need for automated lithic refitting.
We have scanned the products of an experimental lithic
collection to serve as test data for creating a refitting program. The
results of these tests and prospects for future development will be presented
in this paper. Although numerous difficulties remain, we are optimistic
that as 3D scanning technologies improve and research within computer "puzzling"
applications advances, the initial difficulties in the development of automated
lithic refitting will be overcome.

THE CONTRIBUTION OF REFITTING TO THE UNDERSTANDING OF THE LEVALLOIS REDUCTION STRATEGY
At the Middle Palaeolithic workshop site of Taramsa-1
in Upper Egypt, a number of dense lithic scatters were found in primary
context. Raw material volumes exploited from nearby Nilotic gravels were
reduced here according to the Levallois strategy. For one of the scatters,
dated around 65 ky, all the reduction sequences present were completely
refitted.
Analysis of the temporal patterns present in these reductions
shows a clear clustering of patterns. The latter are interpreted as implementations
of individual design patterns by specialist-chertknappers. Spatial distribution
patterns seem to support that interpretation. The paper concludes with
a discussion of some wider implications of these results in terms of
the nature of Middle Palaeolithic lithic reduction systems and behaviourial
complexity.

THE INTERPRETIVE POTENTIAL OF LITHIC REFITS IN A MIDDLE PALEOLITHIC SITE: THE ABRIC ROMANÍ (CAPELLADES, SPAIN).
The Abric Romaní (Romaní rockshelters) has
provided a thick stratigraphic sequence including several Middle Paleolithic
archaeological levels dated between 40 and 70 ka BP. These levels have
been exposed over large surfaces and are characterized by a high temporal
resolution. Moreover, many structures, including hearths, have been documented.
This allows spatial analysis to be developed. Refitting of lithic artifacts
forms a substantial part of this analysis. The refits obtained at a series
of levels excavated in recent years and dated between 45 and 52 ka BP have
provided some interesting results especially concerning three main issues:
a) the definition of spatial units, especially in hearth-related assemblages;
b) the organization of campsites and the connection between activity areas;
and c) the temporal relationships between the artifacts and spatial units.
