Additional human remains from Blombos Cave, South Africa: (1999-2000 excavations)

The uppermost Middle Stone Age (MSA) layers at Blombos Cave contain high densities of Still Bay bifacial points. Information from other regional sites places the Still Bay prior to the Howiesons Poort industry, which has been dated at 65-70 ka. The Blombos Cave MSA strata have yielded nine human teeth or dental fragments. Four that were recovered during the 1997-1998 excavations have been published elsewhere. The remaining five were discovered during the 1999-2000 field seasons; these are described here. Three of the new specimens are deciduous teeth, and two are permanent premolar and molar crown fragments. The entire dental sample probably represents at least five and as many as seven individuals. The deciduous teeth from the upper MSA levels are likely to have been exfoliated in the cave. One deciduous tooth and the permanent tooth fragments from the lower MSA levels probably represent three individuals who died in or near the cave. The Blombos Cave premolars preserve horizontal circum-cervical striae suggestive of palliative tooth pick use. Approximately half of the permanent and deciduous crown diameters exceed those of recent Africans; for the remainder, the fossil values fall among modern African sample means. The Blombos Cave tooth crowns tend to be smaller than the majority of penecontemporaneous Neandertal teeth. The morphology of the Blombos Cave di is comparable to MSA homologues from the nearby, and presumably somewhat younger site of Die Kelders Cave 1.

船帆洞旧石器遗址可分为上、下两个文化层。在下文化层发现一处人工石铺地面遗存。出土石制品 30 0余件 ,同层出土的哺乳动物化石包括巨貘、中国犀和鬣狗 3个绝灭种 ,其年代应属旧石器时代晚期。上文化层出土物以打制石器与磨制骨、角器共存为主要文化特征 ,其时代应晚于下文化层 ,可能仍属旧石器时代。     

华南晚更新世晚期人类行为复杂化的个案——江西万年吊桶环遗址的发现

吊桶环遗址位于江西万年县境内的大源盆地,是一处坐落在盆地西南边缘的孤立小山顶山的岩厦遗址。岩厦内发现晚更新世晚期以来文化堆积厚达4 m以上。1993-1999年期间曾经过三次发掘,出土了数以千计的石制品,包括石片石器、砾石石器及局部经过磨制加工的石制品,数量众多的动物骨骼遗存。尤为重要的是时代早,数量较多,类型复杂的骨、角及蚌制品的发现,如鹿角斧、骨鱼镖及穿孔蚌壳刀等。与此同时,还有多处用火与居住活动遗迹的发现。这些新发现清楚地记录了晚更新世人类在岩厦内活动的历史,为认识华南地区晚更新世晚期人类的"行为现代性"或"复杂化"进程提供了重要的新证据。     

Human remains from Blombos Cave, South Africa: (1997-1998 excavations)

The Middle Stone Age (MSA) layers at Blombos Cave contain abundant bifacial Still Bay points, formal and ad hoc bone artefacts, and an intentionally incised bone piece. These artefacts add weight to arguments that some aspects of modern human behavior developed earlier in sub-Saharan Africa than elsewhere. Four human teeth were recovered from the MSA strata at Blombos during the 1997-1998 excavations. Two are heavily worn deciduous teeth, and two are incomplete permanent premolar crowns. The Blombos di(1)is comparatively large in relation to modern African homologues, falling within the lower part of the observed Neandertal range. The dm(1)and P(3)are comparable to modern teeth and smaller than most Neandertal crowns. The premolars preserve horizontal circum-cervical striae that suggest palliative toothpick use. The di(1)evinces labial scratches that resemble neither the "cutmarks" that have been observed on Neandertal incisors, nor the striae that have been recorded on modern human teeth.     

Site formation processes at Zhoukoudian, China.

Zhoukoudian is often cited for its human remains and the early evidence of fire. Yet, since its first excavations over 70 years ago, detailed studies of processes responsible for the accumulation of anthropogenic and geogenic sediments in the site have been sparse. This paper provides some details of site formation processes mainly through field observations of the extant section at Locality 1, and the use of soil micromorphology and Fourier Transform Infrared Spectrometry (FTIR) analyses of the sediments. Samples from Layers 10 through 3 show extensive water deposition of fine silt-sized material (reworked loess), including fine-grained organic matter. The dark organic-rich unit in Layer 10--often cited as one of the earliest evidence of fire--is a water-laid accumulation. Much of the fine-grained sediment was derived from outside Locality 1, implying that the site was open to varying extents throughout most of its depositional history. The 4-6 m accumulation of "ashes" in Layer 4 represents subaerial water-laid silt deposits derived from the loess-covered hillslopes surrounding the site. They presumably accumulated in an open depression that formed after the collapse of the brecciated roof deposits represented by Layer 6. Diagenesis is present in many of the Layers, and is exemplified by calcite precipitation and dissolution, and localized apatite (dahllite) replacement of calcite. In Layer 4 diagenesis is more advanced, including calcite/dahllite precipitation, subaerial weathering of the loess and associated precipitation of hematite, alteration of clay and the neoformation of quartz. Many of our conclusions concur with those of Teilhard de Chardin & Young published over 70 years ago.     

Micromorphology and site formation at Die Kelders Cave I, South Africa

The deposits of Die Kelders I were previously described and studied by Tankard & Schweitzer (1974, 1976) from the standpoint of classical granulometric analysis of sand from a coastal cave in order to infer the geological history of the cave and its environs. This paper supplements these earlier works by taking a more holistic approach toward site formation processes by including investigation of the biogenic and anthropogenic influences on the cave deposits and history. The study employs the technique of soil micromorphology, which is the study of resin-impregnated, undisturbed blocks of sediment and petrographic thin sections, in which sediments from all areas of the cave were examined. The study showed that diagenesis of the deposits in the eastern areas of the excavation resulted in decalcification, which in turn brought about slumping and compaction. Equivalent stratigraphic layers exposed in the western and central areas were only mildly decalcified and consequently, these sediments contain limestone rock fall and relatively abundant marine and terrestrial mollusks, the latter not dissimilar to the Late Stone Age (LSA) midden which covers these deposits. Thus, in spite of lowered and more distant shorelines, marine resources were exploited during Middle Stone Age (MSA) times. Observations from these calcareous units also clearly demonstrates that previously recognized "occupational horizons" (e.g. Layers 6, 8 and 10) can be resolved micromorphologically into several ephemeral events, such as burning/fire, redistribution of ashes by wind and water, and non-deposition; the latter is shown by phosphatic alteration of sediments exposed on former surfaces and accumulation of guano, or the presence of millimeter-thick truncation surfaces below which aeolian dust infiltrated. Both field and microscopic observations illustrate that the deposits in caves are highly variable from wall to center, and that excavations should not be localized in just one microenvironment of the cave site.

Middle Stone Age artefacts from the 1993 and 1995 excavations of Die Kelders Cave 1, South Africa

Renewed excavations at Die Kelders Cave 1 on the southern South African coast have uncovered large collections of Middle Stone Age (MSA) stone artefacts and coloring materials, but not bone or shell artefacts. High percentages of silcrete artefacts in one of the lower layers are confirmed, but there is no evidence for the Howieson's Poort stage of the MSA as previously mooted. The artefacts probably date to the middle-late MSA. The consistency and conservation which characterize the Die Kelders and other non-Howieson's Poort MSA artefact sequences contrast with the faster changes and innovative patterning seen in Later Stone Age sequences. It is not known whether this picture is a consequence of the traditional typological approach to MSA stone artefact analysis, or whether it reflects differences between Middle and Later Stone Age tool-makers in biological cognition capabilities or merely in social relations and world views.     

the Risley Bison Kill:West-Central Montana

Abstract

The Risley Bison Jump, a large kill site approximately 50 miles west of Great Falls, Montana, was test excavated in 1974. The badly vandalized site was scheduled to be destroyed by land subdivision.Even though the site was badly disturbed, our excavations show that the site was a well-used bison jump with at least four usages evident. Processing and butchering areas were located along the margins of the kill middens. Side-notched projectilepoints recovered from the site suggest that it dates from the latter part of the Late Prehistoric Period.     

High-precision U-series dating of Locality 1 at Zhoukoudian, China

Thermal ionization mass spectrometric(230)Th/(234)U dating has been carried out on intercalated speleothem samples from the limestone cave occupied by Homo erectus at Zhoukoudian, China. The samples were recently collected in proper stratigraphic context after detailed field examinations. The results show that the age of the No. 5 Skull from Layer 3 is >400 ka, possibly in the range of about 400-500 ka, and that the hominid fossils from the lower strata are at least 600 ka and possibly >800 ka, much older than previously thought. The near-equilibrium(230)Th/(234)U ratios and internal consistency of the dates and stratigraphy lend credence to the results and allow us to comment on their important implications for human evolution.     

Test excavations and initial results at the Middle and Upper Paleolithic sites of Gilvaran,Kaldar, Ghamari caves and Gar Arjene Rockshelter,Khorramabad Valley,western Iran

This paper introduces the excavations in several Paleolithic sites in the Khorramabad Valley, Western Iran. Apart from the two well-known sites of Ghamari Cave and Gar Arjene rock shelter, first excavated by Frank Hole and Kent Flannery in the 1960s, the Gilvaran and Kaldar caves were excavated for the first time. Here we present the stratigraphy of these sites, general data from the lithic assemblages, and the identifications of a small part of the faunal remains. Preliminary results are showing that all of the sites were occupied from the Middle and Upper Paleolithic onward, and therefore provide great potential for the study of the transition between these cultural periods. Our preliminary techno-typological observations show that the lower levels of the Gilvaran and Ghamari sequences may represent an early phase of the Middle Paleolithic.     

Chronological and environmental context of the Middle Pleistocene human tooth from Mollet Cave (Serinyà, NE Iberian Peninsula)

Mollet Cave is a small cave situated in Serinyà (north-east Iberian Peninsula). It was excavated in 1947-48, 1958 and 1972 by Josep M. Corominas. An archaic human molar comes from its base layer (Layer 5). Up till now, this layer has only been dated based on a relative and imprecise chronology of macromammals and the archaeostratigraphic evidence from the early excavations. Recent excavations, conducted between 2001 and 2005, have made it possible to ascertain more precisely the archaeological and palaeontological contents of Mollet Cave, gather microvertebrates, and collect samples for radiometric dating. The aim of this paper is to present the absolute dating of Layer 5, as well as its palaeo environmental and climatic characterisation. The macromammal assemblage seems to have been the result of accumulations produced by the most abundant carnivore, the hyena, which would have used the cave as a den. The results obtained using uranium-series disequilibrium dating ascribe to Layer 5 an age of ca. 215 ka (thousands of years ago), which would correspond to MIS 7. The faunal association suggests a landscape formed by an open and humid woodland characteristic of an interstadial phase, which would have been an environment well suited to sustaining both hyenas and human groups.     

黑龙江省桃山遗址2014年度发掘报告

The deformation of soil by penetrometers and root tips ofPisum sativum

Channels were formed by seminal roots ofPisum sativum and a steel penetrometer of similar dimeter in blocks of remoulded and weathered soil. For both types of channels, the soil was equilibrated and maintained at –12kPa matric water potential during formation. Small samples of soil containing channels were then excavated and examined using a scanning electron microscope. Sections of root channels were found to contain a clearly differentiated zone of newly remoulded soil containing oriented clay. In contrast to channels created by the rigid steel probe, the newly remoulded zone surrounding root channels did not exhibit either a region of maximum soil compression at the channel surface or a radial pattern of shear failure and compression. This micromorphological evidence suggests that exudates may have an additional role to play in reducing the mechanical strength of soil in the proximity of the root tip. The mechanism is thought to operate through an accumulation of soil water related to solute potential and a resultant increase in matric potential.

金牛山人遗址下部地层的热释光断代

金牛山Ａ点剖面分为８层,曾发现有大量化石．１９８４年在Ⅶ层底部见到人骨化石,定名为“金牛山人’．热释光测年结果表明,Ⅵ层下部为１８．８４±１．５１万年;Ⅶ层上部为１９．７０±０．７０万年;Ⅶ层下部为１９．４６±０．３４万年;Ⅷ层上部为３８．８７±５．０７万年．地层年代数据与剖面层序一致,与同层中更新世晚期动物化石时代吻合．可以认为,Ⅵ至Ⅶ层堆积连续而迅速,Ⅶ至Ⅷ层堆积有明显间断．２０万年前,该处曾是一个长时间稳定的洞穴环境．这与“金牛山人”活动所需要的时间与空间相符．     

抚松新屯子西山旧石器遗址试掘报告

古人类遗址湖北郧西黄龙洞的铀系年代

湖北郧西黄龙洞为近年来发现的晚期智人遗址。本文报道该地点具明确层位意义的洞穴次生碳酸盐岩和骨化石样铀系测年的结果。含文化堆积下伏一局部钙板的年代为约100ka BP, 其中部偏上一局部钙板为约77ka BP, 表层钙板形成于27—57ka BP间。人类化石和石制品出土于文化堆积的底部, 其年代应在57—100ka BP, 并很可能在77—100ka BP间。与人牙化石同层的四枚犀牛牙化石在35—72ka BP间, 与基于次生碳酸盐岩的年代框架没有冲突。本文结果为中国现代人类的早期出现和距今40—100ka BP间有人类活动提供了有力证据。
