Abstract

A number of lithic studies over the past several years have indicated that average flake weight (size) appears to be a direct reflection of the ease of lithic procurement, with the greater the distance to the lithic source, the smaller the respective general flake size. Similar high-quality lithic materials from Pot Creek Pueblo and the Cerrita pithouse site of the Taos area of the northern Rio Grande Valley in New Mexico provide an excellent basis for the study of the effects of source distance on the metrical attributes of lithic material due to the wide array of local and nonlocal lithic resources available at varying distances from the two settlements and utilized within them. The analysis indicates that flake thickness and volume (flake length × width × thickness) provide statistically significant linear trends and patterns in relation to respective source material distance. The general flake dimensional-decremental trend with increasing source distance probably reflects smaller lithic parent material sizes with increasing material source distance as well as a lithic technology oriented toward greater material conservation and less technological variability as the distance to the respective lithic material source increases.     

The Organization of Late Paleoindian Lithic Procurement Strategies in Western Wisconsin

Abstract

The applicability of employing an organization of technology framework to the analysis of prehistoric lithic procurement strategies is demonstrated here. Analysis reveals that a spatial separation is present in the distribution of lithic raw materials used by Late Paleoindian populations in western Wisconsin. This raises the possibility that lithic raw material functioned as a stylistic indicator of group membership. To evaluate this suggestion microstylistic traits present on a large sample of diagnostic Late Paleoindian projectile points were examined. Significant differences in stylistic traits were observed between sample areas. Furthermore, these differences correspond to spatial differences in raw material use. The correlation between lithic raw material use and microstylistic traits is consistent with the idea that lithic raw material serves as a stylistic marker of group membership, and indicates the presence of some form of social boundary within western Wisconsin during the Late Paleo indian Period.     

The application and misapplication of mass analysis in lithic debitage studies

The technique of debitage mass analysis based upon size grades of debitage populations is shown to be prone to errors when making interpretations about the kind of tool produced or the kind of lithic reduction technology used. Significant sources of error may originate from differences in individual flintknapping styles and techniques, raw material size and shape variants, and mixing of debitage from more than one reduction episode. These sources of error render debitage Mass Analysis ineffective for determining the kind of stone tool reduction activities practiced at excavated sites. Mass Analysis may be effective for determining artifact reduction sequences if it is used on debitage from a single reduction episode or part of a reduction episode. However, it is shown that Mass Analysis when used for assessing reduction sequence information, must also control for the effects of raw material variability, assemblage mixing, and flintknapping styles.     

Excavations at Prehistoric Sites on the Navajo Indian Irrigation Project,Northwestern New Mexico

Abstract

The results of a large excavation project in the San Juan Basin of NW New Mexico are summarized in this article. Discussion is limited to prehistoric and protohistoric sites, 22 of which were excavated. The majority of the remains are small, surface aceramic sites that are believed to relate to the Archaic Cultural Complex. These sites reflect a specialized adaptive strategy focusing on seasonal mobility and the exploitation of resources occurring at or adjacent to sand dunes. The lithic assemblages from these sites generally are homogeneous and reflect opportunistic usage. Occupation of the project area during the Anasazi phases was limited. A considerable protohistoric Navajo occupation is apparent, with one excavated site suggesting a very specialized economic orientation emphasizing antelope procurement. The research focus of the project was on comprehensive lithic analysis and on paleoeconomy. Several methodological considerations are discussed, as is the necessity for developing a unified research perspective that will produce comparable data for the region.     

Reconnaissance survey for Palaeolithic sites in the Debed River Valley,northern Armenia

Abstract

The southern Caucasus is a critical region for those interested in Palaeolithic research because of its varied topography and location at the crossroads of Europe, Africa, and Asia. Modern Armenia sits at the heart of this area, but has until now played a small role in broader debates, largely because of its paucity of well-excavated and well-dated sites. To improve this situation, a survey was conducted for Palaeolithic sites along the valley of the Debed River (Lori Depression, northeastern Armenia). Twenty-three open-air sites, spanning the Lower through the Upper Palaeolithic periods, were identified. Most of the lithic material is of Middle Palaeolithic manufacture. Upper Palaeolithic material is also well represented, but only a handful of Lower Palaeolithic artifacts have been identified. Test excavations at several sites suggest that they preserve in situ deposits that may help us to understand the role of the southern Caucasus in the Palaeolithic occupation of Eurasia.     

Taphonomy at Hermies,France: A Mousterian Knapping Site in a Loessic Context

Abstract

The recent excavation of Hermies, a Mousterian (Middle Palaeolithic) flintknapping site in northern France, sheds light on natural alteration of a lithic assemblage in a loessic sediment. An extensive, well preserved stratigraphic zone grades into a more disturbed area. During excavation we recorded taphonomic indicators such as the dip and strike of in situ pieces, the scattering of artifacts and refitting of broken specimens, and microscopic alteration, principally natural, of flakes. While the composition of the lithic assemblage is less sensitive to erosion than we would expect, the vertical and horizontal dispersion of finds at Hermies is related to natural processes active in the lower and wetter parts of the site. Of particular note is that the dispersion can be associated with polish produced by the natural growth of roots rather than by human use. Some “tools”conventionally identified as denticulaters and notches display no use-wear, and we suggest they were created accidentally by processes such as shock, trampling, and crushing within dense clusters of debitage. This correlation of debitage clusters with increased presence of notches and denticulates is reported from many open-air Mousterian sites; since these two tool forms define the Denticulate Mousterian facies, some reevaluation of those facies is necessary.     

Book Reviews

Abstract

Obsidian studies play an integral part in archaeology around the world, particularly in the Americas, but few archaeologists have employed obsidian studies to understand Native American life at historical archaeological sites. Yet, obsidian sourcing and hydration analysis can provide critical insights into site chronology and use, lithic recycling, and procurement and trade at contact and colonial sites. Obsidian geochemical sourcing and hydration analyses of a 19th-century rancho site in northern California have revealed new information on Native Americans who labored there in the second quarter of the 19th century. The obsidian data indicate a significant amount of lithic manufacture and use, a change in obsidian procurement in the 1800s, and an unprecedented number of obsidian sources represented on-site. The implications for general obsidian studies, as well as for regional archaeological issues, concern the problems with popular sourcing methods in northern California and the need to revisit current understandings of the first micron of hydration rim development.     

Raw material availability,flaking quality,and hunter–gatherer technological decision making in northern Tierra del Fuego Island (southern South America)

The technological organization and lithic raw material procurement of Holocene hunter–gatherers have been topics of considerable interest in northern Tierra del Fuego Island. Ongoing archaeological investigations indicate that most of the rocks employed by native human populations came from secondary deposits of fluvio-glacial and marine origin. However, a primary geological source for two distinctive lithologies has been recently discovered near the Chorrillo Miraflores Valley (Tierra del Fuego, Chile). These raw materials became the focus of further research since one of them (a silicified tuff) has been identified in several archaeological sites of Tierra del Fuego. Some of these sites are located more than a hundred kilometers away from the source. A regional survey of potential lithic sources along with petrographic and geochemical analyses confirmed that the silicified tuff is only available at Chorrillo Miraflores. Here we present the technological analysis of artifacts manufactured on Miraflores silicified tuff that were recovered from the Argentine portion of northern Tierra del Fuego composed of Espíritu Santo and San Sebastian Capes. The role of utilitarian currencies in the prehistoric use of this lithology is assessed through the application of the Metcalfe and Barlow (1992) field processing model. The results show that this raw material may not have been exclusively selected for its flaking quality, although an alternative functional efficiency hypothesis is also introduced. Finally, its spatially restricted availability as well as unique macroscopic aspect suggests its selection and use may have been mainly influenced by social factors.     

The Duck Lake Site and Implications for Late Archaic Copper Procurement and Production in the Southern Lake Superior Basin

Abstract

Few sites relating to Archaic procurement of copper have been archaeologically investigated in the southern part of the Lake Superior basin. The Duck Lake site, located in the Ontonagon River watershed of Michigan's Upper Peninsula, is within the source area for native copper. Investigations at this site reveal a field camp consisting of one or more occupations by Late Archaic groups. Lithic analysis demonstrates a strong reliance on non-local raw materials, and suggests a degree of residential mobility within a region known to the occupants. Lithic material was obtained through embedded procurement and exchange with more distant groups. Copper likely entered the early Late Archaic exchange system in the Midwest through frequent interactions and trade between groups, and appears consistent with a down-the-line model of exchange.     

Explaining the monopoly in shell-bead production on the Channel Islands: drilling experiments with four lithic raw materials

Significant political and economic developments among the Chumash of southern California were catalyzed in part by the emergence of an intensive, specialist-driven shell-bead industry during the second millennium CE on the Santa Barbara Channel Islands. The production of millions of beads depended in turn on the availability of lithic microdrills of standardized form and materials. Channel Islanders quarried a particular stone type, a blocky Monterey Formation chert, from multiple outcrops situated close to the eastern shores of Santa Cruz Island. Rich archaeological assemblages document the lithic and shell byproducts of these intertwined production systems, each of which endured for several centuries (CE 1150–1819). Islanders invariably chose Island chert for making microdrills: hundreds of thousands of specimens recorded to date are of this material. Furthermore, nearly every microlith in all of Chumash territory (post CE 1150) was produced on the islands; the large populations on the mainland did not participate in microlith making or bead making after CE 1150–1200. We argue that this pattern had its roots not only in the patchiness of key resources and shifting regional social relationships, but also in the physical properties of available raw materials. Here we experimentally assess the properties of Santa Cruz Island chert alongside three important mainland raw materials—Grimes Canyon fused shale, Coso obsidian, and Vandenberg chert—that potentially could have been tapped to make microliths. We test the proposition that Island chert outperforms other lithic materials in drilling efficiency and drill use life. Our experimental results from 108 drilling trials reveal sharp distinctions in performance characteristics across the four materials. We infer that the process by which Islanders became the more-or-less exclusive manufacturers of shell-bead currency in southern California was facilitated by both the efficacy and physical properties of the Island cherts and the propitious locations of the outcrops.     

X-ray fluorescence analysis and intra-island exchange in the Society Island archipelago (Central Eastern Polynesia)

We apply X-ray fluorescence (XRF) geochemical analysis to a collection of 'Opunohu Valley lithic artifacts from Mo'orea island to investigate the local scale of raw material procurement, adze production, use, and exchange within the Society Island archipelago. We use these data to document the distribution of non-local versus local volcanic artifacts in 'Opunohu Valley house sites, ritual sites, and specialized sites, as a means for establishing intra-site production and consumption patterns, and access to exotic, possibly superior, stone resources, and how these two themes correlate with site function or household wealth and status. Overall, 30% of the artifacts analyzed via WDXRF derive from non-local sources, notably two other islands in the archipelago outside of the political boundaries of Moorean chiefdoms. Our case study thus provides the first direct material evidence of intra-archipelago trade and exchange in the Society Islands. Intra-archipelago trade in adzes was certainly in place by as early as A.D. 1350, if not earlier, and continued up until the time of European contact. In addition, our analyses have identified a local adze production locale in the Afareaitu district of Mo'orea island. The patterns of local versus non-local adze production and exchange strongly suggest that dual interaction spheres were involved. The correlation between adzes and adze-related debris produced from off-island sources and sites with specialized use, which were often reserved for the social, ritual, and political elites in Ma'ohi society suggests that some of the exotic adzes derived from gift exchange between Mo'orea and ruling elites in Tahiti and the Leeward Islands. These adzes from afar would have solidified socio-political and ideological alliances between elites in the Windward and Leeward sectors of the archipelago.     

Big fish and great auks: Exploitation of birds and fish on the Isle of Portland,Dorset, during the Romano-British period

Abstract

The paper considers the assemblage of bird and fish bones from a Romano-British settlement on the Isle of Portland, on the southern coast of England. Compared with contemporary sites, the assemblage includes an unusually large number of fish bones from a wide range of marine species, including large cod, other Gadidae, several species of seabream, scad and bass. The bird assemblage includes bones of a butchered great auk. This provides the first evidence that this extinct species was nesting off the shores of central southern England and being exploited for food in this period. Other seabirds identified included razorbill, great northern diver and gannet. The species represented are discussed in relation to other Romano-British sites, particularly the Roman town of Dorchester, situated 15 km away. Many of the species have been discovered on only a few contemporary sites and the presence of the seabream in particular indicates that seawater temperatures may have been warmer than until very recently. Possible cultural changes in diet and food procurement in the Roman period are also considered.     

We will be known by the tracks we leave behind: Exotic lithic raw materials,mobility and social networking among the Côa Valley foragers (Portugal)

The aim of this study is to establish different socio-cultural models based on lithic raw material sourcing integrated with regional rock art distributions to infer social behaviours within the context of central Iberian Upper Palaeolithic societies. Specifically, we focus on Upper Palaeolithic hunter–gatherer mobility and social interaction in the Côa Valley. This study relies on a knowledge of regional geology and field work to identify the sources of the lithic raw material found at Côa Valley Upper Palaeolithic sites. We expose the context of use and discard of flint, which is naturally absent from the region, and other local materials. From this, we present a GIS based analysis concerning space, time and least-cost paths travelled. This analysis, along with the environmental data available, forms a baseline to evaluate different anthropological models on hunter–gatherer lithic use, mobility, and social networks. We conclude with a three-level model for social interaction, in the context of aggregation activities between different social meta-groups, which involves embedded procurement, long-distance raw material exchange, and symbolic community, reflected in the largest known open-air Upper Palaeolithic rock art concentration.     

Archaeological survey,paleogeography, and the search for Late Pleistocene Paleocoastal peoples of Santa Rosa Island,California

Abstract

The northern Pacific Coast is an important area for understanding human colonization of the Americas, but Late Pleistocene coastal sites are rare and interglacial sea level rise has inundated the continental shelf and the primary areas where Paleocoastal archaeological sites are likely to occur. Here we outline a terrestrial archaeological survey project designed to identify Paleocoastal sites on Santa Rosa Island, California. Using reconstructions of ancient shorelines and paleogeography, we predicted that sites might be found where lithic resources, freshwater springs, caves or rockshelters, and strategic vistas drew Paleocoastal peoples into the island interior. We identified nine new Paleocoastal sites, including four radiocarbon dated to >11,000 cal b.p. that are among the oldest sites on North America’s Pacific coast. Our targeted survey demonstrates an important technique for investigating island and coastal settings where sea level rise remains a significant challenge for locating early sites.     

Life at the end of the Holocene moist phase in south‐east Arabia — the Late Neolithic site of Jebel Thanais 1 (JTH1)

The surface site of Jebel Thanais 1 is located in the Emirate of Sharjah (U.A.E.) at the western flank of the Jebel Faya/Jebel Buhais anticline structure. A dense scatter of lithic artefacts and fireplaces indicates Stone Age settlement activities in this area. Radiocarbon dates obtained from fireplaces date the occupation of the site to both the beginning and the very end of the fifth millennium cal. BC. During the second half of the fifth millennium the deterioration of climatic conditions in south‐east Arabia had a noticeable impact on settlement patterns and subsistence strategies. While coastal habitation sites from this time are well known along the shores of the Oman peninsula, only a few poorly dated sites allow insights into habitation and raw material procurement strategies and lithic technology in the interior. Investigations into the spatial structure of the site and an analysis of lithic finds will contribute to a better understanding of this period.     

A tale of two sites: Functional site differentiation and lithic technology during the Late Pithouse period in the Mimbres area of Southwestern New Mexico

The raw materials from which stone tools are made can provide considerable information relevant to behavioral variation within a prehistoric population. By examining the stone used for tools from two different types of Late Pithouse period (A.D. 550-1000) residential sites from the Mimbres Mogollon area of Southwestern New Mexico, this paper illustrates how understanding the lithic landscape of a region provides a means to assess behavioral variation in stone procurement practices. The analysis indicates that the differences in mobility and economic pursuits between longer-term residential sites containing pit structures and a shorter-term seasonal residential site with ephemeral architecture structured the raw material procurement practices of site’s occupants. Pit structure sites were focused on agricultural pursuits and used a technology that centered on the production of informal tools fashioned from locally available raw materials. The seasonal residential site focused on wild resources and evidenced greater reliance on formal tool production using raw materials acquired from beyond the immediate vicinity of the site. Despite increasing sedentism and agricultural dependence of the region’s population, some portion of the population exercised seasonal mobility strategies and associated technological and behavioral practices more typical of hunting and gathering populations, suggesting a diverse socio-economic system within the region.     

Bipolar Reduction and Behavioral Variability During the Mid-Late Holocene at Eagle's Nest,Mount Sinai Harbor,New York

Recent syntheses for the Long Island Sound region argue for long-term cultural continuity amongst Holocene coastal hunter-gatherers. These notions derive primarily from studies of quartz lithic assemblages, which archaeologists argue show structural stasis over time. The remaining variability is explained with a ‘distance to source' model in which near-coastal sites tend to show a lack of quartz conservation while interior sites show quartz recycling. Under this model, technological strategies traditionally associated with raw material conservation (e.g., bipolar reduction) should not occur at near-coastal sites. We test the ‘distance to source’ model by reexamining a quartz lithic assemblage from Eagle's Nest-Long Island's richest Holocene coastal hunter-gatherer site. We find conclusive evidence for bipolar reduction in the site's “block/shatter” materials. Toolmakers used bipolar reduction to conserve raw material. Toolmakers also used anvils and bipolar reduction to open quartz cobbles, to stabilize freehand cores, to efficiently access cutting edges, and possibly to create crushed coarse quartz temper for pottery production. Our results point to previously unrecognized aspects of behavioral variability in the Eagle's Nest lithic assemblage and to possible revision of the ‘distance to source’ model. Similar variability may be present at other North American sites with quartz “block/shatter” material.     

Late Pleistocene Techno-traditions in Southern Africa: A Review of the Still Bay and Howiesons Poort, c. 75–59?ka

The focus of this paper is on two remarkable techno-traditions in the prehistory of southern Africa, the c. 75?C71?ka Still Bay and the c. 65?C59?ka Howiesons Poort. These were periods when the technological and behavioural repertoire of early Homo sapiens expanded rapidly to include novel technologies such as heat treatment of lithic materials, pressure flaking of stone points, manufacture of complex armatures including the bow and arrow, and the production of symbolic artefacts including shell beads and engraved ochre, bone and ostrich eggshell. In this paper I first review briefly the historical background relating to the recognition of these techno-traditions; second, concentrate on the archaeological sites known to contain these assemblages within southern Africa; and third, discuss aspects of the precocious material culture that appears during these phases.     

Plants and Technology: Current and Future Directions

Abstract

Located within the driftless area of southwestern Wisconsin, the Withington site provides a unique opportunity to examine the adaptive responses of Early Paleoindians exploiting this region. With a lithic assemblage dominated by Hixton Silicified Sandstone from sources over 170km to the north, chipped stone technological attributes and raw material diversity suggest that the occupants of the site were highly mobile, employed a mixed organizational strategy of toolstone transport, and possessed a wide knowledge of the lithic and social landscape. While our recent understanding of the early archaeological record of this region has progressed, a lack of published reports continues to hinder the incorporation of data from this area into larger models of Early Paleoindian subsistence and settlement. As part of an on-going research effort to address this, I present here a report and analysis of lithic material recovered from the site.     

Systematic Reworking of Lithics from Earlier Cultures in the Early Holocene of Dakhleh Oasis,Egypt

Abstract

A raw material form scarcely mentioned in the literature on lithic production—chipped stone artifacts manufactured by members of still earlier cultures—is used for a substantial portion of the toolkits in certain industries of Dakhleh Oasis, south-central Egypt. In one group of early Holocene (Masara) sites, the majority of double patinated tools are chunky burins, systematically manufactured from Levallois flakes and similar thick-sectioned older artifacts. Since fresh chert and other workable stone is available in the area, it appears that old, recycled lithics constitute the preferred raw material for these tool classes. The sites in question seem to be field camps where the burins were both made and used.
