“…Prepared cores at PL1 (n=27) comprise 12% of the core assemblage and are characterized by preferential (Figure 11, G) and to a lesser extent, centripetal recurrent (Figure 10, H) forms (Boëda, 1991;Boëda, 1993;Boëda, 1995). A comparison of length, width, thickness and weight measures between prepared cores and all other cores from PL1 demonstrate the similarity in length and width values while displaying marked differences in measurements for both thickness and weight (Table 4).…”

“…Similarly, such reduction sequences would form the method of repeated flake detachment for recurrent forms. In effect, primary flakes would have provided the hierarchical delineation between the preparation and production surfaces of the core required for Levallois (prepared core) technology (Boëda, 1991;Boëda, 1993;Boëda, 1995;Chazan, 1997;Van Peer, 1992). In any event, the proposed use of such forms as cores intimately relates to an additional technological aspect of the PL1 core assemblage, the occurrence of cores-onflakes.…”

Existing data suggest weak human occupation of southern Africa's Winter Rainfall Zone (WRZ) during later Marine Isotope Stage (MIS) 3, the causes of which are unknown. Here we report briefly on the results of recent surveys of alluvial terrace sites of the Doring River in the WRZ, which document occupation over a broad expanse of the later Middle Stone Age (MSA) and Pleistocene Later Stone Age. We then report on test excavations at one terrace site, denoted Putslaagte site 1 (PL1), describe in detail the assemblage of flaked stone artefacts produced from that excavation, and present two OSL ages obtained from 0.8 m to 1.5 m below surface. The results suggest that a) artefact accumulations at PL1 are dense, b) the technological systems documented are characteristically MSA but differ in form from the range of systems known from other excavated sites in the region, and c) that the assemblages accumulated in MIS 3. Taken together with the survey data the results introduce new variation into the later MSA in southern Africa, and imply reorganisation of land use in the WRZ in late MIS 3 rather than abandonment. We suggest that a research emphasis on rock shelter deposits may have produced misleading depictions of regional occupation.

“…Las características básicas de los núcleos en su estado final de explotación son las definidas por Boëda (p. ej.

Sin embargo, la gestión del volumen total y el ritmo de la explotación muestran un proceso tecnológico diferente.…”

This study presents the technological structure observed in levels B and Bb (Boreal) from La Cativera. A dual technological pattern is observed. For one side simplified blade exploitation is observed and for the other, a normalized short flake production is documented too. A new ¹⁴C data corroborates the chronological position of both levels despite showing technical schemes which significantly vary from those of synchronous sites. The B and Bb levels match in time with the so called Notched and Denticulate Mesolithic industries, however the observed knapping patterns present a major affinity with the Late Magdalenian or Epipalaeolithic Late Glacial knapping schemes.

Este trabajo presenta la estructura tecnológica observada en los niveles B y Bb (Boreal) de La Cativera, donde se observa una dualidad entre explotaciones laminares simplificadas y una producción de lascas cortas normalizadas. Una nueva datación inédita refuerza la posición cronológica de estos niveles pese a que las estrategias de talla de los mismos difieren significativamente de las documentadas en yacimientos sincrónicos. Los niveles B y Bb coinciden en el tiempo con los conjuntos del Mesolítico de Muescas y Denticulados, sin embargo el análisis tecnológico de la industria lítica lo pone en relación más directa con los conjuntos del Magdaleniense final y/o Epipaleolítico microlaminar propios del Tardiglaciar

“…In contexts without extensive refitting sequences, however, the emic focus has led to the construction of abstract cognitive or volumetric rules, such as Boëda's (1993Boëda's ( , 1994Boëda's ( , 1995 criteria for the production of Levallois and other flaking technologies, but without the evidential support normally associated with other aspects of low-level and middle-level theory in archaeology. Without traditional artifact drawings of debitage and cores (sensu Addington 1986or Inizan et al 1999 accompanied by attribute studies of the dynamic aspects of reduction to substantiate the abstract schematic drawings (e.g., Baumler 1988;Dibble 1987;Henry 1989;Kuhn 1990), there is little evidence independent of the researcher's gestalt for other archaeologists to use to evaluate the validity of the emic interpretations.…”

There are more areas of overlap as well as distinction between the Reduction Sequence and Chaîne Opératoire methods of archaeological analysis than the current debate recognizes. While methodological differences have been acknowledged, high-level theory differs to a greater degree than is currently appreciated, partly due to the social practice of archaeology in different contexts. This paper compares and evaluates examples of reduction sequence and chaîne opératoire research to demonstrate how high-level theory goals impact middle-range theory and even low-level theory practices (i.e., how data are constructed and published). The paper then utilizes the distinction between an emic decision hierarchy and an etic production hierarchy to elucidate how the practitioners of both methods can more successfully integrate their approaches. An alternative to both methods is offered to demonstrate how common epistemological problems can be resolved. As an example of this alternative approach, the paper compares blank production behaviors and tool kit morphologies among Levantine Ahmarian, as well as among Levantine Aurignacian assemblages, from Kebara Cave, Israel. This case study demonstrates that the two Ahmarian assemblages are more different, rather than more similar to each other, in comparison to the Levantine Aurignacian assemblages. This suggests that a typological approach to these assemblages conceals significant behavioral data.
