Modern hunting behavior in the early Middle Paleolithic: faunal remains from Misliya Cave, Mount Carmel, Israel

Understanding the behavioral adaptations and subsistence strategies of Middle Paleolithic humans is critical in the debate over the evolution and manifestations of modern human behavior. The study of faunal remains plays a central role in this context. Until now, the majority of Levantine archaeofaunal evidence was derived from late Middle Paleolithic sites. The discovery of faunal remains from Misliya Cave, Mount Carmel, Israel (>200 ka), allowed for detailed taphonomic and zooarchaeological analyses of these early Middle Paleolithic remains. The Misliya Cave faunal assemblage is overwhelmingly dominated by ungulate taxa. The most common prey species is the Mesopotamian fallow deer (Dama mesopotamica), followed closely by the mountain gazelle (Gazella gazella). Some aurochs (Bos primigenius) remains are also present. Small-game species are rare. The fallow deer mortality pattern is dominated by prime-aged individuals. A multivariate taphonomic analysis demonstrates (1) that the assemblage was created solely by humans occupying the cave and was primarily modified by their food-processing activities; and (2) that gazelle carcasses were transported complete to the site, while fallow deer carcasses underwent some field butchery. The new zooarchaeological data from Misliya Cave, particularly the abundance of meat-bearing limb bones displaying filleting cut marks and the acquisition of prime-age prey, demonstrate that early Middle Paleolithic people possessed developed hunting capabilities. Thus, modern large-game hunting, carcass transport, and meat-processing behaviors were already established in the Levant in the early Middle Paleolithic, more than 200 ka ago.

Inland human settlement in southern Arabia 55,000 years ago. New evidence from the Wadi Surdud Middle Paleolithic site complex, western Yemen

The recovery at Shi’bat Dihya 1 (SD1) of a dense Middle Paleolithic human occupation dated to 55 ka BP sheds new light on the role of the Arabian Peninsula at the time of the alleged expansion of modern humans out of Africa. SD1 is part of a complex of Middle Paleolithic sites cut by the Wadi Surdud and interstratified within an alluvial sedimentary basin in the foothills that connect the Yemeni highlands with the Tihama coastal plain. A number of environmental proxies indicate arid conditions throughout a sequence that extends between 63 and 42 ka BP. The lithic industry is geared toward the production of a variety of end products: blades, pointed blades, pointed flakes and Levallois-like flakes with long unmodified cutting edges, made from locally available rhyolite. The occasional exploitation of other local raw materials, that fulfill distinct complementary needs, highlights the multi-functional nature of the occupation. The slightly younger Shi’bat Dihya 2 (SD2) site is characterized by a less elaborate production of flakes, together with some elements (blades and pointed flakes) similar to those found at SD1, and may indicate a cultural continuity between the two sites. The technological behaviors of the SD1 toolmakers present similarities with those documented from a number of nearly contemporaneous assemblages from southern Arabia, the Levant, the Horn of Africa and North Africa. However, they do not directly conform to any of the techno-complexes typical of the late Middle Paleolithic or late Middle Stone Age from these regions. This period would have witnessed the development of local Middle Paleolithic traditions in the Arabian Peninsula, which suggests more complex settlement dynamics and possible population interactions than commonly inferred by the current models of modern human expansion out of Africa.     

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.     

Art and the Middle-to-Upper Paleolithic transition in Europe: comments on the archaeological arguments for an early Upper Paleolithic antiquity of the Grotte Chauvet art

The spectacular art of the Grotte Chauvet stands out among all other examples of Aurignacian art, which are restricted to a handful of sites in other regions of western and Central Europe, which take the form of sophisticated carvings on organic materials and of simple engravings on rockshelter walls. Given its sophistication, Chauvet has understandably come to feature prominently in debates as to the nature of human symbolic origins, the behavioral capacities of Homo sapiens, the nature of the dispersal of modern humans across Europe, and the possibly contemporary extinction of Homo neanderthalensis. Significant objections to such an antiquity have, however, been made in recent years on the grounds of the style, themes, and technical practice of the art itself, and on the grounds of the AMS radiocarbon dating program that was first seen to suggest an early Upper Paleolithic age. To date, no attention has been paid to claims for an Aurignacian age on specifically archaeological grounds. Here, I undertake a critical examination of the archaeology of the cave and its wider region, as well as attempts to verify the antiquity of the art on the basis of comparison with well-dated Aurignacian art elsewhere. I conclude that none of the archaeological arguments withstand scrutiny and that many can be rejected as they are either incorrect or tautologous. By contrast, hypotheses that the art is of Gravettian-Magdalenian age have not been successfully eliminated. The age of the art of the Grotte Chauvet should be seen as a scientific problem, not an established fact. While it may prove impossible to prove an Aurignacian age for some of the Chauvet art I suggest a set of expectations that would, in combination, strengthen the robusticity of the ‘long chronology’ argument. The onus is upon Chauvet long chronologists to do this, and until they do, we must conclude that the art of the Grotte Chauvet is not dated, and very possibly much younger than claimed.     

Initial excavation and dating of Ngalue Cave: A Middle Stone Age site along the Niassa Rift, Mozambique

Direct evidence for a systematic occupation of the African tropics during the early late Pleistocene is lacking. Here, we report a record of human occupation between 105-42 ka, based on results from a radiometrically-dated cave section from the Mozambican segment of the Niassa (Malawi/Nyasa) Rift called Ngalue. The sedimentary sequence from bottom to top has five units. We concentrate on the so-called “Middle Beds,” which contain a Middle Stone Age industry characterized by the use of the discoidal reduction technique. A significant typological feature is the presence of formal types such as points, scrapers, awls, and microliths. Special objects consist of grinders/core-axes covered by ochre. Ngalue is one of the few directly-dated Pleistocene sites located along the biogeographical corridor for modern human dispersals that links east, central, and southern Africa, and, with further study, may shed new light on hominin cave habitats during the late Pleistocene.     

Impressions of wild cereal chaff in pisé from the 10th millennium uncal B.P. at Jerf et Ahmar and Mureybet: Northern Syria

Pisé (daub or building earth) from Jerf el Ahmar and Mureybet was examined and found to contain plant impressions made by the fine fraction of cereal chaff which had been added to the pisé as a tempering medium. Four wild grasses were identified from impressions, while over fifty taxa were identified from charred remains. Chaff tempering was present in all samples examined and was composed of spikelet bases and fragments of spikelets. Several aspects of these findings complement results obtained from charred remains. The sheer quantity of building material with chaff implies that cereals were widely available. De-husking and winnowing appear to have been carried out on a large scale, probably near the site. Firm evidence for wild rye confirms previous identifications for this period in the middle Euphrates, rye being difficult to distinguish from wild einkorn if only grain is available for identification. The quality of the chaff provides some evidence of crop processing.     

Middle Miocene Cephalotaxus (Taxaceae) from Yunnan,Southwest China,and its implications to taxonomy and evolution of the genus

The infrageneric taxonomy of the genus Cephalotaxus Siebold et Zuccarini ex Endlicher (Taxaceae) is controversial as morphological characters have been doubted to change coherently among species. Although the epidermal features are considered as important characters in the taxonomy of conifers, they have not been systematically studied in this genus. Neogene foliage shoots with well-preserved epidermal structure not only can provide systematic links to the extant species, but also have implications for the taxonomical definition of the extant species by their epidermal features. In this paper, the morphologies of leafy shoots combining epidermal structure of a Neogene Cephalotaxus, which was collected from the middle Miocene of Southwest China, and ten extant species (variants) were studied. Morphology as well as epidermal structures was compared among species (variants) in Cephalotaxus. Based on the comparisons, the taxonomical definition of extant species in genus Cephalotaxus are discussed. Our results indicate that leaf morphological characters in combination with the features of epidermal structure can distinguish species in genus Cephalotaxus. The fossil foliage shoots from the middle Miocene of Southwest China were assigned to a new species, C. maguanensis n. sp., which shows close affinities to the extant C. hainanensis. On the basis of leaf and epidermal information, we suggest there are seven extant species in Cephalotaxus. With global cooling and the uplift of the Qinghai-Tibet Plateau since the middle Miocene, the cooling climate induced the differentiation and southward expansions of C. maguanensis, and its extant offspring, C. hainanensis, is distributed to Hainan Island and the Indo-Chinese peninsula.

Evidence of hunting and hafting during the Middle Stone Age at Sibidu Cave, KwaZulu-Natal, South Africa: a multianalytical approach

Points and point fragments from Middle Stone Age layers (dated to between 50,000 and 60,000 years ago) from Sibudu Cave, KwaZulu-Natal, South Africa, were examined to establish whether they were used as hafted spearheads for hunting. A multi-analytical approach was followed, using macrofracture analysis, use-wear analysis, and residue analysis. In addition to the analytical processes, an experimental project tested the results of the macrofracture analysis on local raw materials. The study shows that points from Sibudu Cave were indeed hafted and used as hunting tools. It was further established that plant twine was probably the preferred binding material to attach the points to wooden hafts. Resin may have been used as an adhesive in combination with the binding material. A detailed examination of the ochre distribution on the points confirmed that ochre was also part of the hafting arrangement. The need to use a dependable methodology for the recognition of hunting and hafting traces on stone points from the southern African Middle Stone Age context is briefly discussed.     

A 14C age calibration curve for the last 60 ka: the Greenland-Hulu U/Th timescale and its impact on understanding the Middle to Upper Paleolithic transition in Western Eurasia

This paper combines the data sets available today for ¹⁴C-age calibration of the last 60 ka. By stepwise synchronization of paleoclimate signatures, each of these sets of ¹⁴C-ages is compared with the U/Th-dated Chinese Hulu Cave speleothem records, which shows global paleoclimate change in high temporal resolution. By this synchronization we have established an absolute-dated Greenland-Hulu chronological framework, against which global paleoclimate data can be referenced, extending the ¹⁴C-age calibration curve back to the limits of the radiocarbon method. Based on this new, U/Th-based Greenland_Hulu chronology, we confirm that the radiocarbon timescale underestimates calendar ages by several thousand years during most of Oxygen Isotope Stage 3. Major atmospheric ¹⁴C variations are observed for the period of the Middle to Upper Paleolithic transition, which has significant implications for dating the demise of the last Neandertals. The early part of “the transition” (with ¹⁴C ages > 35.0 ka ¹⁴C BP) coincides with the Laschamp geomagnetic excursion. This period is characterized by highly-elevated atmospheric ¹⁴C levels. The following period ca. 35.0-32.5 ka ¹⁴C BP shows a series of distinct large-scale ¹⁴C age inversions and extended plateaus. In consequence, individual archaeological ¹⁴C dates older than 35.0 ka ¹⁴C BP can be age-calibrated with relatively high precision, while individual dates in the interval 35.0-32.5 ka ¹⁴C BP are subject to large systematic age-‘distortions,’ and chronologies based on large data sets will show apparent age-overlaps of up to ca. 5,000 cal years. Nevertheless, the observed variations in past ¹⁴C levels are not as extreme as previously proposed (“Middle to Upper Paleolithic dating anomaly”), and the new chronological framework leaves ample room for application of radiocarbon dating in the age-range 45.0-25.0 ka ¹⁴C BP at high temporal resolution.     

Genetic analysis of early holocene skeletal remains from Alaska and its implications for the settlement of the Americas

Mitochondrial and Y-chromosome DNA were analyzed from 10,300-year-old human remains excavated from On Your Knees Cave on Prince of Wales Island, Alaska (Site 49-PET-408). This individual's mitochondrial DNA (mtDNA) represents the founder haplotype of an additional subhaplogroup of haplogroup D that was brought to the Americas, demonstrating that widely held assumptions about the genetic composition of the earliest Americans are incorrect. The amount of diversity that has accumulated in the subhaplogroup over the past 10,300 years suggests that previous calibrations of the mtDNA clock may have underestimated the rate of molecular evolution. If substantiated, the dates of events based on these previous estimates are too old, which may explain the discordance between inferences based on genetic and archaeological evidence regarding the timing of the settlement of the Americas. In addition, this individual's Y-chromosome belongs to haplogroup Q-M3*, placing a minimum date of 10,300 years ago for the emergence of this haplogroup.     

Strontium isotope evidence for migration in late Pleistocene Rangifer: implications for Neanderthal hunting strategies at the Middle Palaeolithic site of Jonzac, France

In order to understand the behaviours and subsistence choices of Palaeolithic hunter-gatherers, it is essential to understand the behavioural ecology of their prey. Here, we present strontium isotope data from sequentially-sampled enamel from three reindeer (Rangifer tarandus ssp.) and a single bison (Bison cf. priscus) from the late Middle Palaeolithic site of Jonzac (Chez-Pinaud), France. The results are used to investigate the ranging and migratory behaviours of these important prey species. We found that the bison had isotope values most consistent with a local range, while the three reindeer had values indicating a seasonal migration pattern. Due to the similarity of the patterning of two of the three reindeer and in conjunction with zooarchaeological results, we suggest that they may have been from the same herd, were likely killed around the same point during their seasonal round and may therefore be the product of a single hunting event or a small number of successive hunting events. The isotope analyses complement the zooarchaeological data and have allowed greater insight into the palaeoecology of these species, the palaeoenvironment, and Neanderthal site use and hunting strategies.     

Morphological and functional development of characters associated with settlement in the yellowfin goby, <Emphasis Type="Italic">Acanthogobius flavimanus</Emphasis>

Morphological and functional development of characters from pelagic larval to benthic juvenile periods in the yellowfin goby, Acanthogobius flavimanus, were examined on the basis of 275 specimens (9.4–25.9mm in standard length) collected in shallow water in the Tama River estuary, central Japan. Judging from the development of osteological features, late pelagic juveniles possessed fully developed swimming and feeding abilities. Rapid changes in various characters, including the formation of a loop-shaped gut, increases in condition factor and teeth number, broader upper-field view capability, and extended scaly area and pigmentation development, occurred during the transition from late pelagic to early benthic periods. Most of the changes were associated with structural and functional aspects enabling more efficient use of benthic resources or the avoidance of predators in the benthic habitat.     

西南喀斯特高原盆地石漠化环境植物群落结构与物种多样性时空动态

为阐明西南典型喀斯特石漠化类型——喀斯特高原盆地石漠化植物群落结构和物种多样性特征及其演变规律,科学支撑喀斯特石漠化治理,选取了喀斯特高原盆地典型石漠化区贵州清镇簸箩小流域为研究区域,对其植被进行广泛的野外勘察,设置典型样方研究其植物群落结构和物种多样性特征;运用空间替代时间方法,研究石漠化演变过程中植物群落结构和物种多样性变化;基于2013—2015连续3 a的监测数据,研究其年际变化。结果表明:研究区群落结构简单,共记录到的植物分布58种,其中草本层18科24属28种、木本层17科25属30种;单种属的比例很高,为82.86%。不同等级石漠化环境植物群落高度、平均地径、平均冠幅、草本层生物量和灌木层生物量均具有显著差异;植物种群密度在不同等级石漠化环境变化依次为轻度石漠化中度石漠化潜在石漠化无石漠化。不同等级石漠化环境植物多样性指数、均匀度指数、丰富度指数和优势度指数均偏低,而且4种指数均与石漠化等级演替无明显耦合关系。不同年份植物群落高度、平均地径、种群密度和灌木层生物量随着时间的推移均呈增加趋势,但相邻年份增加不显著。研究区生态系统人为干扰逐渐减弱,植被呈现出正向演替的趋势,优势种的重要性趋于降低。该研究结果对我国西南喀斯特盆地生态功能恢复和石漠化植被重建具有一定的理论意义和实践指导价值。     

甘肃天水武山县南峪村的维曼嵌齿象及其生物地层学意义(英文)

报道了甘肃天水地区武山县四门镇南峪村地点发现的一件残破的未成年维曼嵌齿象(Gomphotherium wimani)下颌,标本保存有完整的p3,dp4,m1齿列。颊齿齿冠显示出嵌齿象属(Gomphotherium)的一些进步特征,例如齿脊前后压缩,齿谷宽阔,副齿柱后中心小尖凸显,中附锥和中心小尖趋于分裂,有弱的白垩质发育,符合维曼嵌齿象的鉴定特征。维曼嵌齿象此前发现于甘肃的中中新统,而南峪村地点的含化石地层可与周围其他地点的中中新统对比,因此,南峪村地点维曼嵌齿象层位的地质时代为中中新世。同时,结合孢粉学研究的结果,可能说明中中新世时期,天水地区气候温暖湿润,适宜低齿冠的哺乳类如嵌齿象等动物生存。
