The Baumer construct defines the Early and Middle Woodland periods in the lower Ohio Valley in the confluence region of the Ohio, Tennessee, and Cumberland Rivers. Originally defined by University of Chicago investigations in the 1930s, Baumer remains a poorly understood cultural unit. This paper reports the botanical and environmental data from Baumer features excavated in recent work at Kincaid Mounds. These data demonstrate a stable plant food regime highlighted by a major emphasis on nut harvests as well as the cultivation of Eastern Complex seed crops. The Kincaid data show that Baumer and related Crab Orchard groups inhabiting large stream floodplains are more strongly committed to horticulture than their relatives living in small interior stream drainages in southern Illinois. Maize was also recovered but it is clearly of Mississippian origin.  相似文献

Recent radiocarbon dating (Herrmann et al. 2014) found that Serpent Mound was likely built during the Early Woodland period—around 320 BC. Herrmann et al. (2014) also suggested that the effigy was repaired or restored during Fort Ancient times, thereby accounting for the late prehistoric radiocarbon-dated samples recovered by Fletcher et al. (1996). The present article presents new data in support of the Early Woodland construction date. These data include lidar analyses, electrical resistivity ground imaging (ERGI) studies, and iconographic assessments.  相似文献

Chemical weathering of archaeological material is well known; however, while there have been a number of experimental studies demonstrating different types and degrees of chemical alteration on faunal remains, little attention has been paid to stone tools, and the few studies that exist relate mainly to siliceous materials and water‐induced chemical alteration. Azokh Cave, located in the South Caucasus, contains a Middle Pleistocene to Holocene infill, and detailed macro‐ and microscopic examination of the lithic assemblages recovered there indicates potential chemical weathering of the stone artefacts. The cave is also currently home to one of the largest bat colonies in the region, and their guano forms a significant component of the infill of the inner galleries. Based on these two factors, an experimental pilot study was set up to artificially chemically alter a range of stone flakes produced specifically for the task, in order to determine the nature and likely cause of weathering. The experimental flakes, produced from different raw materials, were buried in fresh bat guano for up to two years. The results reported herein demonstrate that in a relatively short time, the highly acidic composition of bat guano strongly affects calcium‐bearing rocks (e.g., limestone, basalt) altering their entire surface. Similar comparisons may be made with chemical alteration evident on archaeological lithics from Azokh Cave, suggesting that bat guano has played a significant role in diagenetic alteration.  相似文献

The Indian Ocean coastline is argued to have been a critical route of modern human dispersal from Africa, introducing Late Palaeolithic industries into South Asia, but a dearth of evidence has prevented a direct evaluation of this. Kachchh (Gujarat, India), located immediately east of the Indus Delta, is an important setting to appraise the Palaeolithic occupation of the western Indian coastline. Targeted survey of Late Pleistocene sediments there found widespread evidence for occupation of Kachchh during the Late Pleistocene: Middle Palaeolithic and possibly Late Acheulean lithic artifacts. The conspicuous absence of Late Palaeolithic industries in these Late Pleistocene deposits, with their presence only noted in Holocene contexts, does not support the model of modern human expansions into India with these industries via the coastal route. We evaluate these results in the context of current debates regarding Late Pleistocene hominin demography, adaptation, and expansions.  相似文献

The Zhokhov site is one of the northern most archaeological sites in the world and a very ancient vestige of occupation of high latitudes by people, indicating that this territory was settled as early as about 8000 years ago. Investigation of the site began in 1989–1990 and then continued in 2000–2005. Here we consider the taphonomy, spatial distribution, species and age- and sex-related composition of the faunal remains from the Zhokhov site. These data allow conclusions regarding the subsistence strategy practiced by Zhokhov inhabitants, including the hunting tactics. This was a peculiar adaptation model based on reindeer and polar bear hunting in a 2:1 ratio. Reindeer hunting was all-seasonal, whereas polar bears were hunted mostly in winters at their dens. Mortality data for reindeer and polar bears depict the yearly subsistence cycle. The Zhokhov site is found to be a base camp occupied year-round with modest summer activities, while wintertime is characterised by intense polar bear hunting. Most reindeer were hunted in the fall. Subsistence strategy of the Zhokhov hunters was largely facilitated by the fact that at the time of occupation Zhokhov Island was still part of the coastal Siberian plain margin.  相似文献

This paper investigates changes in subsistence strategies at the upland cave site of Nugljanska (Croatia) at the end of the last ice age, during a time of rapid sea level rise and changing environment. We analysed the faunal assemblage from archaeological levels spanning the Pleistocene–Holocene transition (15,000–8000 years BP) and evaluated changes in relative abundance of species, measured species diversity, and compared the representation of terrestrial mammal and marine resources. We found a significant shift in the most abundant prey species exploited (from red deer, Cervus, to wild boar, Sus). There was some correlation between dietary diversification and periods of increased moisture availability and the spread of deciduous forest in the area. Our results suggest that there was a continuing reliance on terrestrial resources throughout time and that changes in dietary patterns were likely due to local environmental change and potentially, changing seasonal mobility strategies, at the Pleistocene–Holocene transition.  相似文献

黄河流域是中国早期铜器起源与发展的关键区域,早期铜器的演进受社会复杂化程度制约。在文明化进程的视野下,本文通过用铜遗存的考古信息与社会经济背景,将黄河流域早期铜器的演进分为早期用铜的萌芽、发展初期及区域化特征形成三个阶段,初步阐释铜制品从出现到规模化使用的过程。人群流动、定居农业、手工业生产、城市与权力的集中是影响黄河流域早期铜器演进模式的重要因素。大体在公元前2300年至前1400年的文明进程中,黄河上游铜器的制作与使用具有相似的风格及开放共融的特征,而黄河中下游地区防御性城市与权力的发展,推动了铜器技术与社会功用的本土化转变。  相似文献

The Homo erectus cranium found at Gongwangling, near Lantian, China, and dated to ≈1.2 ma BP has been analyzed with respect to its evolutionary position. However, the remains, and especially the internal and external surfaces of the neurocranium, present a series of marked abnormalities. These irregularities consist principally of a pronounced cresting and scalloping of the external surface of the frontal bone and anterior parietal bone and a similar alteration of the internal surface of a mid transverse section of parietal bone that connects with the fossilization break across the anterior parietal bone. There is no obvious exposure of diploë on the surfaces. Woo (Vertebrata PalAsiatica 10:1–16, 1966) briefly ascribed these abnormalities to postmortem erosion, and Caspari (Am. J. Phys. Anthropol. 102:565–568, 1997) has attributed the irregularities of the right supraorbital torus to antemortem trauma. It has been suggested that the pervasive neurocranial alterations might be pathological. Computerized tomography (CT) analysis of the frontal and parietal bones revealed complete radiopacity of the anterior half of the fossil; it is possible to distinguish large frontal sinuses but other details, including in the area of the purported traumatic lesion, are invisible. However, in the posterior frontal bone and preserved portions of the parietal bone the diploë and tables are discernible. Externally on the frontoparietal section and internally on the transverse parietal piece, there are clear erosional lacunae in the associated table, combined with a thin layer of matrix which obscures the eroded diploë externally. The superficial irregularities are therefore due to postmortem taphonomic alterations of the bone and not pathological processes. In addition, it is apparent that the two pieces were embedded in the matrix at different angles, resulting in their differential erosion.  相似文献

This paper presents the find of a Mammuthus primigenius carcass and associated Mousterian implements from the Last Glacial site of Asolo, in north-eastern Italy. We review the exploitation of proboscidean carcasses at Lower and Middle Paleolithic sites of Africa, Europe and the Levant, including evidence of elephant killing, and summarize recent research on hafting and use of Mousterian points as spearheads already before the end of the Middle Pleistocene. The bones and implements from Asolo are described in detail; we provide information on other Italian sites with mammoth remains and on the Mousterian record of the north-eastern quadrant of the peninsula. A possible impact fracture has been detected on a Levallois point from Asolo; its interpretation is based on comparisons to similar scars found on spear points of verified function from archaeological sites of later age, and on experimental material. We conclude that the evidence of Asolo is consistent with information from a number of Western European sites supporting a picture of Neanderthals as capable hunters of large game, such as woolly mammoth.  相似文献
