ABSTRACT There is still debate about when and how the peopling process of South America developed, particularly in southern Patagonia. Earliest evidence corresponds to chronologies beginning at circa 11,000 radiocarbon years ago. Regarding the archaeological record, discussions about early peopling often have been related to the existence of a particular type of projectile point: the fishtail point. This work aims to evaluate the initial peopling of southern Patagonia by mainly focusing on the processes which operated in central-western Santa Cruz province (Argentina). We analyze the distributions of fishtail points as well as stemless projectile points, which also could be related to early occupation contexts. Likewise, other evidence is considered, such as the differential use of black obsidian coming from the important source of Pampa del Asador.
摘要：关于南美洲，特别是巴塔哥尼亚南部的人口进程在何时以及如何发展，仍存在争议。最早的证据对应于大约11000年前放射性碳开始的年代。关于考古记录，关于早期人的讨论通常与一种特殊类型的射弹点的存在有关：鱼尾点。这项工作旨在通过主要关注在中西部圣克鲁斯省（阿根廷）运行的过程来评估巴塔哥尼亚南部的初始人口。我们分析了鱼尾点和无杆抛射点的分布，这也可能与早期的职业背景有关。同样，也考虑了其他证据，例如来自Pampa del Asador的重要来源的黑黑曜石的不同使用。

ABSTRACT This contribution analyzes the charcoal records found in archaeological sites dating to the Pleistocene/Holocene transition (9032 ± 30 - 10,672 ± 56 radiocarbon years ago) located in the eastern Tandilia Range, Buenos Aires province, Argentina. The archaeological charcoal identified for the Pleistocene/Holocene transition were Celtis ehrenbergiana, Salix humboldtiana, Schinus sp., Colletia sp., Baccharis sp., and Senecio sp. Charcoals with high caloric values and long combustible duration were an excellent source of heat and were probably used by hunter-gatherers for heating, cooking, and lighting. The presence of xerophytic forests at least from ca. 10,000 radiocarbon years ago in the eastern Tandilia Range were inferred by the record of C. ehrenbergiana found in four archaeological sites during the Pleistocene/Holocene transition. During this period, vegetation developed under a cold arid to semi-arid climate.

ABSTRACT The Page-Ladson site, currently buried and submerged in a sinkhole in northwestern Florida, demonstrates evidence of human occupation in North America by 14,550 calendar years ago (cal yr BP). This paper combines new diatom evidence with existing palynological data to strengthen paleoenvironmental interpretations at the site. The Page-Ladson sinkhole was not entirely submerged between ∼15,100 and 14,400 cal yr BP. Conditions at the site became warmer and wetter, and the sinkhole became a turbid pond from ∼14,400 to 12,900 cal yr BP. From ∼12,900 cal yr BP until ∼11,000 cal yr BP, a disappearance of diatoms in the coring location suggests the sinkhole margin was dry. Water levels rose between 11,000 and 9000 cal yr BP, submerging the coring location on the pond margin. These environmental data help contextualize the archaeological data in the region.

ABSTRACT In a recent article published in PaleoAmerica, authors Metin I. Eren, David J. Meltzer, and Brian M. Andrews describe a set of Clovis-like artifacts recovered from an Archaic context at Goodson Rock Shelter, Oklahoma. With this discovery, they conclude that we cannot reliably recognize true Clovis assemblages and sites, especially caches, without true Clovis points, and that we should not consider other technological characteristics such as overshot flaking and prismatic blade manufacture as unequivocally representing Clovis. In this essay, we propose two additional working hypotheses that potentially explain the reported record from Goodson Rock Shelter: (1) the assemblage is not a Clovis look-alike at all; or (2) the assemblage is Clovis, but mixed with artifacts from younger occupations. We respectfully call on Eren, Meltzer, and Andrews to provide additional information about the Goodson Rock Shelter assemblage’s context and associations, as well as a more thorough luminescence analysis of the site’s lowest deposits.
摘要在《古美国》杂志最近发表的一篇文章中，作者Metin I.Eren、David J.Meltzer和Brian M.Andrews描述了在俄克拉荷马州古德森岩石避难所从古代环境中发现的一组类似克洛维斯的文物。根据这一发现，他们得出的结论是，如果没有真正的克洛维斯点，我们就无法可靠地识别真正的克洛维斯组合和地点，尤其是藏匿处，我们不应该认为其他技术特征，如套鞋剥落和棱柱形刀片制造，明确地代表了克洛维斯。在这篇文章中，我们提出了两个额外的工作假设，这两个假设可能解释了Goodson Rock Shelter报道的记录：（1）这个组合根本不像克洛维斯；或者（2）这个组合是克洛维，但混合了年轻职业的文物。我们恳请Eren、Meltzer和Andrews提供有关Goodson Rock Shelter组合的背景和关联的更多信息，以及对该场地最低矿床的更彻底的发光分析。

ABSTRACT Sites in north-central Chile have yielded late-Pleistocene megafauna bone remains, occasionally associated with human-made artifacts. However, little is known about the depositional characteristics, the conditions that allow their preservation, and how to identify recurrences facilitating their discovery. This work presents contextual and stratigraphic data, coupled with radiocarbon dates on bone material from surface findings and excavations conducted in Los Vilos (Coquimbo, Chile), which show that this area was rich in Pleistocene terrestrial mammals and that alluvial sequences and dunes have allowed bone preservation and exposure. These results have implications for the search for new evidence and for the interpretation of their historical trajectories. Radiometric age distribution indicates mainly terminal-Pleistocene specimens with the potential of some taxa persisting into the Holocene. These results are used to discuss coexistence and interaction scenarios between extinct faunas and the early record of human beings in the region.

ABSTRACT The diffusion of Northeast Asian microblades and their relation to human migration are key issues to understanding the peopling of the Americas. However, understanding of this process is hindered by a lack of a cultural framework for terminal Pleistocene Central China. This paper reviews data from microblade sites located in Central China dating to Marine Isotope Stage 2, uses a modified typology based on the chaîne opératoire to build a chronological sequence of changing lithic technology and typology, and further divides the Central Chinese sequence into four main phases: 29,000–22,000 cal yr BP, 22,000–17,000 cal yr BP, 17,000–14,000 cal yr BP, and 14,000–10,000 cal yr BP. By comparing this chronology with established sequences for other parts of Northeast Asia, it is evident that these technological phases appeared in different orders across the region, which is best explained by human migrations driven by climate change and possibly transition in adaptive strategies.
东北亚微叶片的扩散及其与人类迁移的关系是了解美洲人类定居的关键问题。然而，由于缺乏对中国中部更新世末期的文化框架，对这一过程的理解受到了阻碍。本文回顾了中国中部地区自海洋同位素第2阶段以来的微叶片遗址资料，采用基于cha ne opacimatoire的改良类型学，建立了岩石技术和类型学变化的年代学序列，并将中国中部序列进一步划分为4个主要阶段:29000 ~ 22000 cal yr BP、22000 ~ 17000 cal yr BP、17000 ~ 14000 cal yr BP和14000 ~ 10000 cal yr BP。通过将这一时序与东北亚其他地区已建立的序列进行比较，很明显，这些技术阶段在整个地区以不同的顺序出现，这最好的解释是由气候变化驱动的人类迁徙和可能的适应策略转变。

ABSTRACT This paper presents and discusses the analysis of the lithic assemblage from a newly discovered archaeological site, Cueva Alí Mustafá, located in the eastern sector of the Tandilia Range (Buenos Aires, Argentina). Lithic artifacts associated with several hearths and scattered fragments of charcoal were dated in 10,450 ± 38 and 9032 ± 30 radiocarbon years ago, respectively. The site is interpreted as an ephemerally occupied camp in which lithic knapping activities were carried out, related to the late and final stages of stone-tool manufacture. The use of a wide variety of lithic raw materials from different sources was identified, most frequently two sedimentary varieties, one of which is a fine-grained rock whose source is more than 100 km from the archaeological site, and another, a medium-grained rock that is locally available. Other rocks were identified in lower frequencies, including, remarkably, the presence of silicified limestone which can be traced to more than 500 km away.

ABSTRACT Red chert attributed to the Munsungun Lake geologic formation located in northern Maine is common in terminal-Pleistocene, fluted-point-period lithic assemblages throughout New England. A visually identical material also appears in some later-period sites in coastal Maine. Until recently no bedrock source for this red chert showing convincing evidence of precontact use was known. Here we present the NKP site complex, a series of quarry-related stone-tool-manufacturing workshop sites associated with outcrops of high-quality red/green chert. These outcrops represent the only known source of this material with evidence of precontact human use within the Munsungun Lake formation. Although unequivocal fluted-point-period artifacts, such as fluted bifaces, are not yet documented at the NKP complex, the recurrent appearance of red Munsungun chert in fluted-point-period lithic assemblages in New England suggests the manufacture of fluted points took place in the vicinity of these outcrops.

ABSTRACT The central lowland of Beringia (aka the Bering land bridge) has been viewed alternately as a barrier or a refugium to the Native American founder population during the Last Glacial Maximum (LGM). Here we suggest that an equally – if not more – likely LGM home for the founder population is the arctic zone of Beringia. People were drawn to eastern arctic Beringia during the post-LGM Younger Dryas (YD) cold period and occupied western arctic Beringia during the cold interval preceding the LGM (GS5/HE3). Arctic Beringia probably contained adequate resources for an LGM human population, especially across the exposed East Siberian Arctic Shelf (“Northwest Beringian Plain”), which supported an extensive steppe-tundra habitat populated by mammoth and other large mammals before and during the LGM. An arctic Beringian refugium would explain a growing body of evidence that indicates an early (or pre-) LGM divergence of the Native American founder population from its Asian source.

ABSTRACT In this paper, we make a quantitative analysis of spatial patterns for the earliest archaeological component (early Holocene) at Cueva Maripe, a multiple-activity site located in Santa Cruz province (Patagonia, Argentina). We worked in a geographical information systems environment to systematize the analogical and digital information from excavations including the location of registered hearths, the frequency of lithic artifacts and bone remains, and the distribution of burnt materials. The visualization techniques and spatial statistics allowed us to define the intra-site structure of the site. Results suggest that Cueva Maripe was probably used as a short-term temporary camp. This spatial approach leads to a better understanding of the formation and occupation history of the site, as well as a method for comparing different intra-site use patterns between sites.
