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.     

Geoarchaeological investigations at the Topper and Big Pine Tree sites,Allendale County,South Carolina

The Topper and Big Pine Tree sites are located along the central Savannah River in South Carolina. Both sites contain significant Clovis horizons and the Topper site is reported to contain a pre-Clovis assemblage characterized by a smashed core and microlithic industry. The stratigraphic position of the early assemblage at Topper is indeed below Clovis and radiocarbon and luminescence ages support its pre-Clovis age. However, the human origin of the proposed artifacts has not been conclusively proven. The late Quaternary stratigraphic sequence developed for this segment of the Savannah River provides support for a regional pattern of river metamorphosis over the last 50,000 years in southeastern U.S. streams.     

Clovis Blades at Paleo Crossing (33ME274), Ohio

Abstract

This paper describes the previously undocumented Paleoindian lithic blade assemblage from the Paleo Crossing Site, Ohio (33ME274). Qualitative and quantitative comparisons of the Paleo Crossing blade assemblage to blade assemblages from other Paleoindian sites demonstrates its fragmented and utterly exhausted nature, but support its designation as Clovis. This is significant given that a majority of the Paleo Crossing toolstone outcrops 600 km southwest of the site in southern Indiana and western Kentucky, a prominent locale for Clovis prismatic blade manufacture. We propose that blade reduction was practiced for prolonging the use-life of distally retouched endscrapers, a prominent tool form at Paleo Crossing. Since use-wear and ethnographic evidence often show that endscrapers were used for hide-working, Paleo Crossing may be an appropriate venue to test for the presence of intense caribou hide-working.     

Evaluation of the protective shelter at Blackwater Draw Archaeological Site,New Mexico

Abstract

Blackwater Draw Archaeological Site is located in Roosevelt County, New Mexico, and is the type site for the Clovis culture which dates back 12,000 years. In 1995 the stakeholders for Blackwater Draw convened a meeting with an expert consultant to evaluate the efficacy of a protective shelter proposal. The purpose of the proposed shelter was to protect palaeo-Indian finds excavated in 1983–4 and displayed in situ. Recommendations were made and, several years later, shelter construction was completed. In 2000, the shelter as built was re-evaluated.     

Pre-Clovis in Texas? A critical assessment of the “Buttermilk Creek Complex”

Lithic artifacts from the lowest strata of the Debra L. Friedkin site, located on Buttermilk Creek in central Texas, have been interpreted as an undisturbed pre-Clovis assemblage (Waters et al., 2011a). Stone tools and debitage were recovered from sediments stratified just below diagnostic Clovis artifacts and dated by OSL to between 13.2 and >15.5 cal kya. Invoking commonly observed cultural and natural site formation processes, we offer an alternative explanation of the “Buttermilk Creek Complex” as a Clovis assemblage in secondary association with the dated sediments.     

Reconsidering the Antiquity of Trade on Madeline Island: A View from the Cadotte Site in Northern Wisconsin

Abstract

The Cadotte site, excavated in 1961, is often cited in archaeological and ethnohistorical literature as an example of a short term, mid-seventeenth century refugee encampment of the Huron and/or Odawa circa 1660–1670. A closer examination of the site assemblage has resulted in a reassessment of the general assumptions regarding the site and its use by Huron and Odawa during the mid-seventeenth century. The ceramic assemblage indicates that the site was occupied much earlier and for a longer period than previously understood, circa 1620–1670. This is supported by the European trade goods assemblage. It is also argued that the site served a specialized function, as a place of seasonal rendezvous for the Ontario Odawa and their central Algonquin trading partners. Further, the character of the pottery suggests that a portion of the sample may reflect Algonquin mimicry of Ontario Wendat traditions. The revised understanding of the time depth and function of the site, as well as the character of its associated ceramic assemblage, has also prompted the reconsideration of the identity of the Algonquin groups who visited the island, and the antiquity of the Ojibwe presence at this locale.     

Early Hominin Paleoecology

Abstract

This paper reports on the zooarchaeological and archaeobotanical remains from the initial season of excavations at the Norse period site at Undir Junkarinsfløtti in the Faroe islands. These remains represent the first zooarchaeological analysis undertaken for the Faroes and only the third archaeobotanical assemblage published from the islands. The excavated deposits are described and the key findings from the palaeoenvironmental remains highlighted within the context of the wider North Atlantic environmental archaeology of the Norse period.     

Reburial and protective covering of ancient mosaic pavements: The experience of the conservation department of the Israel Antiquities Authority

Abstract

Four case studies are presented illustrating different attempts to protect excavated ancient mosaics by reburial or protective covering, with varying degrees of success, at three archaeological sites in Israel: Tel Itztaba, a site excavated between 1991 and 1994 where planning for reburial at the outset of the excavation could have prevented considerable losses; Khirbet Minya (Horvat Minim), a site excavated in the 1930s, reassessed after four years of reburial; the Promontory Palace at Caesarea Maritima, a site excavated in 1978, partially destroyed by the sea, reburied and regularly monitored since 1994; and an experimental test site at Caesarea Maritima. These examples demonstrate the importance of planning, monitoring and maintenance for successful reburial, and allow an assessment of which materials and methods performed better than others.     

Preservation of the Stone Age site of Isimila,Tanzania

Abstract

The Stone Age Acheulean site of Isimila is one of the most important sites in Tanzania. Excavated in the late 1950s, it has been open to the public since 1958. This note reviews the problems of preserving in situ the open-air activity floors excavated at Isimila, and describes measures taken by the Tanzanian authorities to manage and protect the site.     

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.     

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.     

Archaeobotanical investigation of two Scythian-Sarmatian period pits in eastern Ukraine: Implications for floodplain cereal cultivation

Abstract

Two Scythian-Sarmatian period pits dated to the 5th–1st centuries b.c. were discovered while excavating the Chalcolithic site of Zanovskoe, located on a floodplain of the Donets River in the steppe region of eastern Ukraine, Lugansk oblast. No contemporaneous settlement sites are known in the region. Archaeobotanical analysis was conducted on charred plant macrofossils recovered from pits at the site. The crop assemblage consisted of hulled barley and broomcorn millet, from which AMS radiocarbon dates were obtained. Other identified plant species mostly constituted arable weeds and wetland plants. The archaeobotanical assemblage implies floodplain cereal cultivation strategies among the steppe inhabitants during this period.     

Akhalkalaki: The Taphonomy of An Early Pleistocene Locality in the Republic of Georgia

As part of our investigations into the potential of the Republic of Georgia for providing information on early hominin occupation of Eurasia, we report here on Akhalkalaki, a large late Early Pleistocene locality located along the lower slopes of a Miocene andesitic cone. Originally excavated in the 1950s as a palaeontological site, it was re-opened in the 1990s and stone tools were found associated with the fauna, suggesting that it is also an archaeological occurrence. Excavations in the 1950s and 1990s uncovered thousands of bones of an early Galerian fauna, including the remains of new species of Hippopotamus,Equus , and Canis (Vekua, 1962, 1987) and dominated by the remains of Equus süssenbornensis. We present the stratigraphy of the site, which together with faunal correlations and reversed paleomagnetics indicates an age most likely in the late Matuyama Chron, probably between 980,000 and 780,000 years ago. Taphonomic analysis suggests that the fauna was deposited and buried over a short time period, and was heavily modified by carnivores, but we cannot demonstrate involvement by hominins. Based on evidence of abundant krotovina (animal burrows filled with sediment) and the lack of definitive evidence for hominin modification to the bones, the stone tools at the site may have been mixed in with the older fauna. The taphonomic characteristics of the Akhalkalaki bone assemblage are not readily explained with reference to assemblage formation processes developed with actualistic studies that have been mostly conducted in Africa, including carnivore dens, predator arenas, human hunting and scavenging, mass deaths, or attritional bone deposition. Because of extreme anthropogenic modification of the present environments, the temperate setting, and the presence of mainly extinct taxa, local models based on actualistic studies cannot approximate the mammalian ecology reflected in the Akhalkalaki bone assemblage. A few comparisons are made with preliminary taphonomic observations from Dmanisi, an Early Pleistocene Homo ergaster site not far away.     

Bioturbation of Submerged Sites by the Asiatic Clam: A Case Study from Amistad Reservoir SW Texas

Abstract

Burrowing clams represent a poorly studied threat to shallowly buried and submerged archaeological sites across North America. Test excavations at a formerly submerged prehistoric terrace site in SW Texas unearthed burrowing clams (Asiatic clam Corbicula fluminea) in, under; and around features. A review of this clam's ecology, burrowing habits, geographical distribution, and presence in this and other archacological sites illustrates the potential for significant sediment disturbances.     

The Palaeolithic of the Bosphorus Region NW Turkey

Abstract

A survey of open-air sites in NW Turkey identified 16 Palaeolithic sites. Analysis of nearly 2000 lithics identified Lower, Middle, and Early Upper Palaeolithic (EUP) components. The Lower Palaeolithic is represented by a core-chopper/flake assemblage at one site and an assemblage with small bifaces at another. Middle Palaeolithic assemblages similar to the typical Balkan Mousterian were found at most sites, and an EUP assemblage similar to the Balkan Aurignacian was found on the Black Sea coast. Later Upper Palaeolithic cultures, e.g., Gravettian or Epigravettian, were not found. Palaeolithic sites were also not found in Turkish Thrace west of Büyük Çekmece, and a palaeoenvironmental barrier, perhaps a channel connecting the Marmara and Black Seas, may have existed before the Bosphorus was opened in the Holocene. A difference in the distribution of Lower-Middle Palaeolithic sites and EUP sites was also noted. EUP sites are clustered on the Black Sea coast while earlier sites are found in the interior and on the shores of the Sea of Marmara. This change in settlement pattern may support a hypothesis of cultural change between the Middle and Upper Palaeolithic and perhaps the replacement hypothesis for the peopling of Europe by early modern humans.     

Quebrada Tacahuay,Southern Peru: A Late Pleistocene Site Preserved by a Debris Flow

Abstract

Here we describe the properties of a debris flow apparently generated by a warm phase El Niño event that buried an intermittently occupied Late Pleistocene forager site located in the southern coastal desert of Peru. Although the event deposited roughly one meter of sediment over the initial occupation, our analyses of debris flow dynamics and data from large scale archaeological investigations indicate that the earliest anthropogenic deposits at the site of Quebrada Tacahuay were preserved intact as a result of the burial episode; there is no evidence that the debris flow scoured or disturbed the cultural deposits. The event that buried the oldest archaeological contexts at Quebrada Tacahuay differs from other flood events that are characterized by turbulent, fast-moving floodwaters. Our data on debris flow dynamics and our results from excavation have implications for identifying, investigating, and interpreting other deeply buried archaeological sites both in the central Andes and in other geographic regions.     

Endurance in the Canyon: Assessing preservation at a multi-component site on the Southern High Plains,USA

Abstract

Preservation decisions often have to be made regarding the long-term status of deeply buried sites. However, the opportunity to evaluate these decisions practically, decades later, is rare. The Nash site, on the Southern High Plains of the USA, is one site where reinvestigation has permitted the assessment of a well-stratified site after an intervening period of thirty years during which it was impacted by dredging and impoundment. The current condition of the site has generated challenges in both recovery and conservation of material. Renewed fieldwork at the Nash site highlights the need to evaluate preservation options while critically considering the effects of geomorphic, taphonomic, and cultural processes.     

Clovis,Folsom, and Midland components at the Debra L. Friedkin site,Texas: context,chronology, and assemblages

The archaeological transition from Clovis to Folsom and Midland in the North American Great Plains coincides with the end of the Pleistocene and onset of the Younger Dryas. Comparisons exploring the adaptive changes that took place during this period frequently employ regional-scale approaches. The focus on regional-scale analyses largely results from the dearth of sites repeatedly visited by multiple early Paleoindian groups. However, regional-scale comparisons have the potential to overlook smaller-scale differences. The Debra L. Friedkin site, Texas offers an opportunity to study Midland, Folsom, and Clovis technology and site-use at a single site. This paper presents the context and chronology of the Midland, Folsom, and Clovis assemblages and a site-scale analysis of lithics from the Friedkin site. It is argued that point production and late-stage reduction were primary activities, and the use of bifacial cores for flake tools was important throughout these occupation periods. Site use at Friedkin differs from early Paleoindian occupation at the nearby Gault site and expands our understanding of settlement and technological organization in the region.     

Civic and Residential Settlement at a Late Preclassic Maya Center

Abstract

The Late Preclassic period in the Maya Lowlands (300 B.C.–150 A.C.) documents the transition toward increased social and economic complexity culminating in the Classic Maya civilization (250–900 A.C.). The Late Preclassic Maya community of Cerros in northern Belize has revealed a settlement pattern of dispersed household clusters and scattered public architecture. Moreover, the site manifests a clear, three-part concentric zonation, similar to later Classic period communities. The authors' analysis provides a definition through time of civic and residential architecture and of the division between elite and non-elite domiciles. The study draws heavily on a functional analysis of the excavated ceramic assemblage. The unique settlement pattern of the semitropical Maya is suggested to be an environmental adaptation with rural elites coordinating the dispersed sustaining population through public monuments and associated ritual.
