Terminal Pleistocene–Early Holocene lithic technological organization around Lake Mojave,California

Abstract

The surface lithic scatters at two areas around Soda Lake were intensively surveyed and 3133 artifacts were analyzed in the field using four main variables to infer how Terminal Pleistocene–Early Holocene foragers organized lithic technology around pluvial Lake Mojave, California. Results indicate that early stage bifaces and flake tool blanks were created at a fine-grained volcanic (felsite) quarry/workshop complex in the Soda Mountains survey area and transported elsewhere. In addition, fine-grained volcanic bifaces were reduced and bifaces and flake tools of cryptocrystalline silicates and obsidian were finished, used, and/or discarded at a habitation area on the ancient shorelines near Little Cowhole Mountain. Comparisons with nearby sites of similar ages (at Ft. Irwin and China Lake) reveal many similarities in lithic technological organization. Lake Mojave—an important locus of prior research—can now be integrated into recent Mojave Desert and Great Basin technological organization studies.     

The Hogeye Clovis cache,Texas: quantifying lithic reduction signatures

The Hogeye Clovis cache is comprised of 52 late-stage bifaces, finished points, and knife/cores cached in central Texas. Because these artifacts were all likely made and cached approximately 13,000 years ago by one or a handful of knappers belonging to a single band with a shared Clovis cultural template, Hogeye provides a rare opportunity to investigate Clovis lithic reduction signatures. This paper builds on previous analyses and presents new methods for quantifying Clovis biface production signatures, including serial flaking and the timing of last overshot flaking. The results show that the Hogeye cache bifaces technologically and morphologically differ from other regional Clovis biface reduction signatures. Additional data is needed to determine whether these differences reflect individual knapping preferences or regional cultural signatures. The methods used and developed here are not Clovis-specific and could be modified and combined with other analytical techniques to identify reduction signatures in biface assemblages from other times and places.     

A quantitative assessment of intraspecific morphological variation in Gahagan bifaces from the southern Caddo area and central Texas

ABSTRACT

This investigation aggregates intact or reconstructed Gahagan bifaces from the southern Caddo area and central Texas to test the hypothesis that Gahagan biface morphology differs between the regions. The Gahagan bifaces (n=102) were scanned, then analyzed using a novel landmarking protocol and the tools of geometric morphometrics. Results provide a preview of the significant differences in Gahagan biface morphology expressed between the southern Caddo area and central Texas regions. The size discrepancy represents an inversion of current theoretical constructs that posit a decrease in tool size thought to articulate with an increase in distance from the raw material source. It is posited that the contrasting morphologies represent two discrete communities of practice; one (emergent Caddo horticulturalists) where Gahagan bifaces were enlisted primarily for burial and ritualistic activities, and the other (central Texas hunter-gatherers) where Gahagan bifaces were utilized over a longer time span in more practical and utilitarian contexts.     

Flakes Crossing the Straits? <Emphasis Type="Italic">Entame</Emphasis> Flakes and Northern Africa–Iberia Contact During the Acheulean

The entame core method was defined after studying the Acheulean bifaces from the site of Ternifine, Algeria. This specialized core method for the production of larges flakes (>10 cm) used for biface blanks involves the detachment of primary large flakes from skillfully selected quartzite cobbles. While technologically simple, a competent selection of raw material and dexterous detachment of the flake resulted in a blank perfectly suitable for the production of bifaces, with minimal further shaping required. This core method resulted in high frequencies of entame blanks in the Ternifine lithic assemblages, as well as from the Iberian Peninsula Acheulean, but not in assemblages from other large flake Acheulean sites. It is suggested that the frequent use of the entame core method common to both North Africa and the Iberian Peninsula indicates similarity in lithic tradition during the Acheulean. This may support the view of North African origin for the Iberian Acheulean during the Middle Pleistocene.     

PINE BARRENS AND POSSUM’S RATIONS: EARLY ARCHAIC SETTLEMENT IN THE NORTH CAROLINA SANDHILLS

Abstract

Competing models of Early Archaic settlement in the Southeast propose broad-scale organization conditioned by either lithic raw material availability or seasonal exploitation of biotic resources and social interaction. We offer a view from beyond the quarries and away from the river with data from the North Carolina Sandhills, a unique physiographic zone of the interior Coastal Plain. Analysis of the distribution of Early Archaic sites at Fort Bragg, including posited upland base camps, raw material use, and application of GIS least-cost path analysis, suggests intensive interriverine settlement, with watershed divides serving as conveyance corridors between high-quality toolstone areas in the Piedmont and resource blooms in the Coastal Plain. Some settlement changes are evident within the Early Archaic sequence, including a gradual shift from logistical to residential mobility and infilling of the local landscape. In the proposed Sandhills model, biocultural needs, social interaction, and requirements for high-quality toolstone are identified at the local band level. Mobility and settlement are considered to be broadly structured by networks of interriverine trails between the major resource areas of the Piedmont and Coastal Plain. Aspects of both the bandmacroband model and Uwharrie-Allendale model apply to the Early Archaic record of the Sandhills, but with closer affinities to the latter.     

Experimental analysis of the practical limits of lithic refitting

We report on the results of an experiment aimed at determining the effects of experience/aptitude, lithic reduction type (biface v. core), and flake size cut-offs on different rates of success in refitting studies. We found that experience matters, but that there can be large differences in aptitude for refitting; that cores are easier to refit than bifaces; and that the effort of refitting increases considerably for flakes smaller than 5–6 g. We propose the use of an asymptotic equation fit to a cumulative curve as a way to determine when a study has reached the point of diminishing returns for a given flake size cut-off, and to help determine differences in aptitude for refitting.     

From Crafting to Caching: Technological and Iconographic Analyses of Blue Creek Cache 37

This paper presents technological and iconographic analyses of a Late Classic (a.d. 600–830) lithics cache recovered from the ancient Maya site of Blue Creek, Belize. The cache consisted of 21 obsidian prismatic blades and a number of chert artifacts, including 21 stemmed bifaces, a large laurel leaf biface, and a tridentate eccentric. The technological analysis of the stemmed bifaces identified three distinct stem production techniques that may be attributable to a combination of idiosyncratic knapping gestures and laterality, or handedness. A survey of Maya iconography demonstrated that large laurel-leaf bifaces and tridentate eccentrics occur in scenes depicting sacrifice and the burning of human remains, often by ritual specialists titled ch’ajoom, or “person of incense.” It is suggested that the presence of a large laurel-leaf biface and tridentate eccentric in the cache may indicate that Blue Creek was the residence of ch’ajoom at some point during the Late Classic period.     

Clovis biface technology at the Topper site,South Carolina: evidence for variation and technological flexibility

The Topper site in the South Atlantic Coastal Plain of South Carolina provides a rare glimpse of the entire range of Clovis tool manufacture. Topper is a quarry-related site along the Savannah River with an outcrop of Coastal Plain chert and a buried Clovis component. This paper focuses on the 174 bifaces and diagnostic debitage from recent excavations to understand biface production at Topper. I present the process of manufacture then measure the variation in production characteristics at the site in terms of our current knowledge of Clovis biface technology. I conclude that Topper flintknappers used reduction strategies typical of Clovis-period tool production but created a biface assemblage with greater flexibility in design than documented at most other Clovis sites. This variation in biface production suggests greater variability in Clovis behavior across America—Clovis groups adapted to local resource conditions and adjusted the organization of their technology accordingly.     

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.     

CONFIRMATION OF AN ARCHAIC PERIOD MOUND IN SOUTHWEST MISSISSIPPI

Abstract

Site 22LI504 is a predominantly Archaic period site in Lincoln County, Mississippi. One of its primary elements of interest is a single conical mound from which small-diameter cores revealed evidence of advanced pedogenesis. A radiocarbon sample from one soil core produced a date suggesting that the mound was Archaic in age (Fulmer 2001); however, it was unclear whether the sample came from within the mound or an underlying midden. In the spring of 2006, we excavated a 1-x-1-m unit in the mound to investigate this question. Diagnostic lithic artifacts, an advanced state of soil horizonation, and a lack of ceramics indicate that the mound is of Archaic period construction, with as many as five construction stages and artifact-rich features. We describe the soil profiles, features, and artifacts recovered from the mound, with comparisons to excavation units in an adjacent Archaic midden to show that there is no clear evidence for the mound being a functionally specific locus. We also present radiocarbon dates that indicate the earthwork is over 5,000 years old. These results are evaluated within the broader context of Archaic mound building, focusing in particular on environmental parameters underlying bet-hedging behavior.     

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.     

Kariandusi: Acheulean morphology and the question of allometry

Allometry, or size-related variation, is shown to be an important factor in the bifaces of two separate assemblages from the Acheulean site of Kariandusi in Kenya. Such variation has functional and possibly stylistic implications. The paper gives a review of the archaeology of Kariandusi, and then investigates the question of size and shape variation in bifaces. The Upper Sites at Kariandusi, first investigated by L. S. B. Leakey, have yielded many obsidian bifaces which can be dated to approximately 0.7–1.0 myr ago. Material from the Lower Site, including many lava bifaces, is judged to be stratigraphically younger but probably in the same time range. We show by making comparisons with the neighbouring Acheulean sites of Kilombe and the Kapthurin Formation that allometry is present in biface assemblages at least 0.5 myr different in date; that similar principles of allometry operate in all the assemblages; and that where there are differences of allometric pattern, within-site variation is sometimes greater than variation between distant sites. We conclude that the size of a biface at least partly determines the shape in which it was made, and that sites in the time range ofHomo erectus and earlyHomo sapiens show surprisingly similar allometric patterns.

Résumé Il est démontré que l'allométrie ou variation dimensionnelle, est un facteur important des bifaces de deux collections séparées du site acheuléen de Kariandusi au Kénya. Une telle variation a des implications fonctionnelles et peut-être aussi stylistiques. Cet article examine l'archéologie de Kariandusi, puis étudie la question des variations de dimensions et de formes dans les bifaces. Les sites plus élevés de Kariandusi, que L.S.B. Leakey a été le premier à fouiller, ont donné de nombreux bifaces d'obsidienne que l'on peut dater d'environ 0,7–1,0 million d'années. Le matériel obtenu dans le site inférieur, y compris de nombreux bifaces en lave, est jugé plus récent stratigraphiquement, mais probablement de la même période. En faisant des comparaisons avec les sites acheuléens voisins de Kilombe et de la Formation Kapthurine, nous démontrons que l'allométrie est présente dans des collections de bifaces dont les dates diffèrent d'au moins 0,5 million d'années; que des principes d'allométrie similaires s'appliquent à toutes les collections; et que lorsqu'il y a des différences de schéma allométrique, la variation au sein d'un même site est souvent plus importante que la variation entre des sites distants. Nous concluons que la dimension d'un biface détermine au moins partiellement sa forme, et que les sites de la période de l'Homo erectus et du début de la période de l'Homo sapiens présentent des schémas allométriques étonamment semblables.

     

Late Classic Maya lithic production and exchange at Rio Bec and Calakmul,Mexico

Abstract

The organization of production and exchange of everyday lithic items is important in defining Classic period lowland Maya economic organization, but the current debate relies on the study of a few lithic workshops, whereas little is known about the consumers’ quotidian acquisition of everyday tools. I suggest looking at the problem from the point of view of the household and distinguishing local from nonlocal production by comparing experimental and quantitative data. Examination of the chert collections from households at Rio Bec and Calakmul enabled me to distinguish two different types of chert biface production and distribution during the Late Classic period (a.d. 650–800), namely by means of markets and itinerant craftsmen. Both sites had very different political organizations, but households from both cities acquired lithics through similar networks, showing that this particular aspect of the domestic economy probably had little to do with political power and centralization in the region.     

Determining the use of Late Archaic shell rings using lithic data: “ceremonial villages” and the importance of stone

ABSTRACT

Late Archaic shell rings have been the focus of archaeological research for decades, yet their history, use, and function are debated. Relying on an evidentiary line rarely used in shell ring studies – the analysis of stone tools and debitage – we test prevailing theories and find that models describing the rings as circular dams intended to hold freshwater are incorrect. Instead, by tracing the origins of stone and its distribution within two shell rings on St. Catherines Island, Georgia, we posit that shell rings were places of both daily residence and intermittent gatherings. Because they have proven useful in interpreting the St. Catherines Island shell rings, we suggest archaeologists shift their sampling and recovery techniques so that representative lithic assemblages can be attained from other rings, thereby providing a better understanding of ring-builders and the Late Archaic occupation of the South Atlantic coastline.     

10,000 Years in the Rocky Mountains: The Helen Lookingbill Site

Abstract

Located in a spring-fed meadow at 2620 masl, Helen Lookingbill is a stratified, high-altitude open site in the Washakie Range of the Absaroka Mountains in NW Wyoming. The site contains cultural material ranging in age from Paleoindian through Late Prehistoric periods. Although the densest cultural deposits date to the Early Archaic (8000–5000 b.p., uncalibrated), other time periods are well represented. A 10,400 year old layer comprises the earliest component (Haskett/Hell Gap) in the main excavation area; above it is a series of Late Paleoindian, Early Archaic, later Archaic, and Late Prehistoric components. The major materials at the site are chipped stone and bone, while a deer bone bed dating between 6500 and 6800 b.p. is contained within the main excavation block. In addition to deet; the site contains the remains of mountain sheep, bison, porcupine, and other mammals. Located on and near both quartzite and chert stone sources, the mountain meadow served as a prehistoric camp site and yielded evidence of tool production, heat treatment, refurbishing, and use. Interdisciplinary research provides much information pertinent to understanding the nature of site occupation with implications for regional cultural dynamics, high altitude hunter-gatherer adaptations, and site formation processes.     

Rocks are heavy: transport costs and Paleoarchaic quarry behavior in the Great Basin

Central place foraging models are used to investigate assemblage variability at two Paleoarchaic (terminal Pleistocene/early Holocene) dacite quarries in the central and eastern Great Basin. Our analyses focus specifically on biface reduction and how varying degrees of reduction relate to the costs of transporting the resulting products upon departing the quarry. Our results suggest that when the distance to be traveled to a residential base is great, reduction will proceed further at the quarry than if the residential base is fairly close. Further, a residential site assemblage will consist of bifaces at later stages of reduction than its associated quarry.     

EARLY WOODLAND SETTLEMENT AND MOUND BUILDING IN THE UPPER TENSAS BASIN,NORTHEAST LOUISIANA

Abstract

Traditionally overlooked because it lacks hallmarks of material and cultural complexity, Early Woodland in the Southeast is an interval of significant transformation in material culture, settlement, and social organization. Investigations at four sites in northeast Louisiana provide insights into changes taking place at this time. These sites are situated on a crevasse splay created by flooding at the end of the Archaic. This flooding is associated with an occupation hiatus ca. 3000–2500 cal B.P. Evidence suggests a rapid colonization of the crevasse splay by people using Tchefuncte pottery, and there is no evidence at these sites of stratigraphic or cultural continuity from Poverty Point. The Early Woodland occupation in the study area dates ca. 2400–2100 cal B.P., which is later than dates associated with Early Woodland in the Pontchartrain Basin and contemporary with Lake Cormorant culture sites farther north. Early Woodland in northeast Louisiana is marked by a diagnostic Tchefuncte ceramic assemblage and the presence of a settlement system composed of small villages or hamlets nucleated around a conical mound that presumably served as a ceremonial/ritual center. This mound was erected very rapidly; radiocarbon dates suggest it was constructed in no more than 10 years. Although mound building has been suspected, this is the first conclusive evidence it was an aspect of Tchefuncte settlement and ceremonial practices. Data from these sites bear on the question of cultural and demographic continuity and change at the Archaic to Woodland transition. Previous models emphasize continuity of populations with ceramic technology and styles diffusing into the lower Mississippi Valley. In contrast, our data support a model of Early Woodland repopulation of the lower Mississippi Valley from the south and east following a prolonged period of regional abandonment.     

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.     

Economic and environmental changes during the 4th and 3rd millennia BC: the 25th Jubilee Symposium of the AEA in Bad Buchau,southern Germany

Abstract

This study represents the first detailed published analysis of a relatively large archaeologically derived faunal assemblage in eastern Beringia for the Late Pleistocene/Early Holocene. The faunal remains, dated to 10,100 cal. BP, are well preserved and have highly resolved spatial association with lithics and hearth features. Factors in the formation of the assemblage are assessed through analyses of weathering, presence/absence of carnivore damage, fragmentation patterns, bone density, and economic utility. Taphonomic analyses indicate that human transport and processing decisions were the major agents responsible for assemblage formation. A spatial model of wapiti and bison carcass processing at this site is proposed detailing faunal trajectories from the kill sites, introduction on site in a central staging area to peripheral marrow extraction areas associated with hearths and lithic items. Data from mortality profiles, spatial analysis, and economic analysis are used to interpret general economy and site function within this period in Interior Alaska. These data and intersite comparisons demonstrate that considerable economic variability existed during the Early Holocene, from broad spectrum foraging to efficient, specialized terrestrial large mammal hunting.     

Archaeological Publications

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.
