许昌人遗址研究的新收获及展望

许昌人遗址位于河南省许昌市灵井镇,2005-2017年发掘,揭露面积500余平方米,2007、2014年在9号探方出土包括2颗"许昌人"头骨在内的5个古人类个体,大量的石制品和21种哺乳动物化石。头骨具有东亚古人类、欧洲尼安德特人和早期现代人的镶嵌特征,可能代表一种新型的古老型人类。石制品研究显示,石核类型多样,且以小型双锥形盘状石核为特色;小型工具类型分异明显、加工精细,显示出不同于旧石器时代早期遗址中的工具技术,而与西方旧石器时代中期遗址工具技术上的特点较为一致。此外,遗址出土7件软锤工具,以动物长骨或鹿角为原料,用以修理石质工具。软锤工具的发现,对于认识中国旧石器时代技术的发展有重要意义。通过对遗址形成过程的分析,"许昌人"生活时期的沉积环境经历了三个阶段:下部灰绿色滨湖相粉砂堆积所指示的水流动力相对较弱的沉积环境,中部综红色粉砂堆积所指示的水流动力相对较强的沉积环境,以及上部浅棕红色粉砂堆积所指示的相对冷湿、水动力仍然较强的沉积环境。尽管存在水动力强弱上的相对变化,但水动力总体上并不大,以低能量水流为主,文化遗物属于原地埋藏。今后将开展人类艺术行为能力、古人用软锤和压制法制作石器的技术、动物埋藏学和年代学等方面的深入研究。     

Geographic views of human development

Human development can be divided into three stages: human ancestors (Lower Palaeolithic), early human races (Middle Palaeolithic) and modern humans (Upper Palaeolithic). Regional differentiation has been detected in the Lower Palaeolithic and is strongly developed in the Middle Palaeolithic but continues into the Upper Palaeolithic less marked. Clearly mixture at all levels accounts for this. Early humans absorbed the pre-existing regionalizations even as they further differentiated. Modern humans resulted from Upper Palaeolithic people spreading across the world and again absorbing the previous differentiations.     

The Middle-to-Upper Palaeolithic transition in Cova Gran (Catalunya, Spain) and the extinction of Neanderthals in the Iberian Peninsula

The excavations carried out in Cova Gran de Santa Linya (Southeastern PrePyrenees, Catalunya, Spain) have unearthed a new archaeological sequence attributable to the Middle Palaeoloithic/Upper Palaeolithic (MP/UP) transition. This article presents data on the stratigraphy, archaeology, and ¹⁴C AMS dates of three Early Upper Palaeolithic and four Late Middle Palaeolithic levels excavated in Cova Gran. All these archaeological levels fall within the 34-32 ka time span, the temporal frame in which major events of Neanderthal extinction took place. The earliest Early Upper Palaeolithic (497D) and the latest Middle Palaeolithic (S1B) levels in Cova Gran are separated by a sterile gap and permit pinpointing the time period in which the Mousterian disappeared from Northeastern Spain. Technological differences between the Early Upper Palaeolithic and Late Middle Palaeolithic industries in Cova Gran support a cultural rupture between the two periods. A series of 12 ¹⁴C AMS dates prompts reflections on the validity of reconstructions based on radiocarbon data. Thus, results from excavations in Cova Gran lead us to discuss the scenarios relating the MP/UP transition in the Iberian Peninsula, a region considered a refuge of late Neanderthal populations.     

L’Aurignacien archaïque de la grotte El Castillo (Espagne) : caractérisation technologique et typologique

In this paper, we present the techno-typological study of level 16 of El Castillo cave (Archaic Aurignacian). In this level, we can identify an important bladelet production from schémas opératoires of unipolar prismatic cores, carinated endscraper and carinated burins types. Besides, we find a specific production of Discoid conception. The retouched blanks, though scanty, are dominated by the Dufour bladelets. Level 16 is in relation with the Archaic Aurignacian at the Cantabrian Iberia, which is present in sites like Cueva Morín, Labeko Koba, Gatzarria, or Isturitz and it also is in relation with the Mediterranean Archaic Aurignacian. Finally, we analyse the different hypotheses about the Initial Upper Paleolithic origin in Europe. The mosaic hypothesis is acceptable for us.     

Femoral curvature in Neanderthals and modern humans: a 3D geometric morphometric analysis

Since their discovery, Neanderthals have been described as having a marked degree of anteroposterior curvature of the femoral shaft. Although initially believed to be pathological, subsequent discoveries of Neanderthal remains lead femoral curvature to be considered as a derived Neanderthal feature. A recent study on Neanderthals and middle and early Upper Palaeolithic modern humans found no differences in femoral curvature, but did not consider size-corrected curvature. Therefore, the objectives of this study were to use 3D morphometric landmark and semi-landmark analysis to quantify relative femoral curvature in Neanderthals, Upper Palaeolithic and recent modern humans, and to compare adult bone curvature as part of the overall femoral morphology among these populations.Comparisons among populations were made using geometric morphometrics (3D landmarks) and standard multivariate methods. Comparative material involved all available complete femora from Neanderthal and Upper Palaeolithic modern human, archaeological (Mesolithic, Neolithic, Medieval) and recent human populations representing a wide geographical and lifestyle range. There are significant differences in the anatomy of the femur between Neanderthals and modern humans. Neanderthals have more curved femora than modern humans. Early modern humans are most similar to recent modern humans in their anatomy. Femoral curvature is a good indicator of activity level and habitual loading of the lower limb, indicating higher activity levels in Neanderthals than modern humans. These differences contradict robusticity studies and the archaeological record, and would suggest that femoral morphology, and curvature in particular, in Neanderthals may not be explained by adult behavior alone and could be the result of genetic drift, natural selection or differences in behavior during ontogeny.     

Technologie,typologie et analyses fonctionnelles de l’outillage lithique durant le néolithique ancien dans la Cueva de Murciélagos de Zuheros (Córdoba,Espagne) : réflexions sur la néolithisation du sud de la Péninsule Ibérique

The cave of Murciélagos de Zuheros (Cordoba, Spain) is one of the most important sites in Southern Iberian Peninsula. Its thick chronostratigraphic sequence includes occupations ranging from the Middle Palaeolithic to Roman times. Occupation levels corresponding to the earliest farming communities that established in modern-day Andalucia are remarkable due to its archaeological richness. This article focuses on the study of the lithic industry from these Early Neolithic levels, which is approached according to various tightly connected questions: raw material characterization, technical systems of production, and morphology and function of tools. Obtained results in their archaeological context are related to the questions on the origin of the Neolithic in Southern Iberian Peninsula.

Chronologie du Paléolithique supérieur dans le Nord-Est de la principale île du Japon

Palaeolithic archaeology in Tohoku region has long been discussed on constructing chronology, however it is difficult to build reliable chronological order because of poor stratigraphic excavations. In recent radiocarbon dating has advanced. In this paper I discuss the relation between chronology and radiocarbon dating in Tohoku region. At first, I categorize the Palaeolithic industries and establish the chronology by analyzing tool typology, lithic technology, and stratigraphic data. I correlate it with radiocarbon data from sites in Tohoku region. The result of analysis shows that Upper Palaeolithic industries are divided into 18 categories and 8 periods on chronology. The calibration curve IntCal 13 indicated that oldest Early Upper Palaeolithic site appeared around 37,000 cal BP, and late Upper Palaeolithic started about 27,000 cal BP. The pottery first appeared as far back as around 16,000 cal BP. Now we do not have enough radiocarbon data, so we have to gather and examine more ¹⁴C data.     

The earliest evidence for the use of human bone as a tool

We report on the analysis of three human cranial fragments from a Mousterian context at the site of La Quina (France), which show anthropogenic surface modifications. Macroscopic and microscopic analyses, including SEM observation, demonstrate that the modifications visible on one of these fragments are similar to those produced on bone fragments used experimentally to retouch flakes. The microscopic analysis also identified ancient scraping marks, possibly resulting from the cleaning of the skull prior to its breakage and utilisation of a resulting fragment as a tool. The traces of utilisation and the dimensions of this object are compared to those on a sample of 67 bone retouchers found in the same excavation area and layer. Results show that the tool size, as well as the dimensions and location of the utilised area, fall well within the range of variation observed on faunal shaft fragments from La Quina that were used as retouchers. This skull fragment represents the earliest known use of human bone as a raw material and the first reported use of human bone for this purpose by hominins other than modern humans. The two other skull fragments, which probably come from the same individual, also bear anthropogenic surface modifications in the form of percussion, cut, and scraping marks. The deliberate versus unintentional hypotheses for the unusual choice of the bone are presented in light of contextual information, modifications identified on the two skull fragments not used as tools, and data on bone retouchers from the same layer, the same site, and other Mousterian sites.     

A general view of the lower Palaeolithic of Turkey

Turkey is one of the rich countries in terms of the Lower Palaeolithic period. The favourable climatic and environmental conditions and quality stone raw material resources in the Pleistocene period caused the country to be heavily occupied by the people of the Lower Palaeolithic. Turkey has biface and flake industries of the Lower Palaeolithic period. Biface industries are more common in open-air sites and are often linked to the Acheulean. Biface tools are only found in the deposits of Karain Cave. The eastern and south-eastern parts of Turkey are the densest regions in terms of biface industries. This density decreases towards the west. However, this general appearance may have resulted from the insufficient level of excavations and surveys of Palaeolithic archaeology throughout the country. In this article, we try to draw a general framework of the Lower Palaeolithic period in Turkey, based on the important Lower Palaeolithic settlements in the country.     

Des silicites dans le Paléolithique ancien et moyen du Maroc occidental

A first diachronic examination of the use of silicites by Early and Middle Palaeolithic hominins in the Moroccan Meseta is presented. An in-depth study of the origins of the different geo-materials was carried on series from five recently excavated sites in northern Meseta at Casablanca — Unit L and Grotte à Hominidés at Thomas Quarry I, Grotte des Rhinocéros and Grotte des Gazelles — and in the southern Meseta at Djebel Irhoud cave. They show that flints from the Phosphates Plateau were the most widely used, from the earliest moments of the Early Palaeolithic (at least 1.3 Ma), but their predominant use for lithic artefacts coincides here with the appearance of the MSA (around 0.35 Ma).     

New discoveries and interpretations of hominid fossils and artifacts from Vindija Cave, Croatia

Beginning with excavations during the 1970s, Vindija Cave (Croatia) has yielded significant Middle and Upper Paleolithic fossil and archaeological finds. We report on seven recently identified hominid fossils, a newly associated partial hominid cranial vault from level G(3), nine possible bone retouchers, and a revised interpretation of the Mousterian artifact assemblage from the site. This new information reinforces our knowledge of the complex biocultural phenomena revealed in unit G and earlier deposits at Vindija. Six of the new hominid fossils derive from stratigraphic units G and I, while one lacks exact provenience. All specimens preserving diagnostic anatomy are from Neandertals. One of the postcranial remains, a radius fragment which exhibits Neandertal-like anatomy, comes from level G(1)and is congruent with the previously established association of Neandertals with an early Upper Paleolithic industry at the site. The partial cranial vault represents the most complete Neandertal from Vindija. The possible retouchers derive from unit G. Our analysis of these artifacts suggests that both percussion and pressure techniques may have been used by Neandertals in the final stage of tool production (retouching). This paper also presents a revision of the artifact analysis for late Mousterian level G(3). We separated raw materials into two main groups due to the differing ways that the materials fracture and the differing morphology of the debitage. The use of raw material in level G(3)is different from earlier Middle Paleolithic levels at Vindija. This indicates that the G(3)late Neandertals were making choices regarding source material somewhat more like the Upper Paleolithic people at the site. When interpreted within a larger regional framework, the Vindija archaeological and hominid fossil remains demonstrate a complex, mosaic pattern of biocultural change in the Late Pleistocene of south-central Europe.     

A new chronostratigraphic framework for the Upper Palaeolithic of Riparo Mochi (Italy)

The rockshelter of Mochi, on the Ligurian coast of Italy, is often used as a reference point in the formation of hypotheses concerning the arrival of the Aurigancian in Mediterranean Europe. Yet, the site is poorly known. Here, we describe the stratigraphic sequence based on new field observations and present 15 radiocarbon determinations from the Middle Palaeolithic (late Mousterian) and Early Upper Palaeolithic (Aurignacian and Gravettian) levels. The majority of dates were produced on humanly modified material, specifically marine shell beads, which comprise some of the oldest directly-dated personal ornaments in Europe. The radiocarbon results are incorporated into a Bayesian statistical model to build a new chronological framework for this key Palaeolithic site. A tentative correlation of the stratigraphy to palaeoclimatic records is also attempted.     

The fragmented character of Middle Palaeolithic stone tool technology

The importance of the transport of stone artefacts in structuring Neandertal lithic assemblages has often been addressed, but the degree to which this led to fragmentation of lithic reduction over Middle Palaeolithic landscapes has not been explicitly studied thus far. Large-scale excavations of Middle Palaeolithic open-air sites and refitting studies of the retrieved assemblages have yielded new, high-resolution data on the mobile aspects of Neandertal stone tool technology. In this paper, we integrate lithic technology and raw material data from recent studies of Middle Palaeolithic open-air and rock shelter sites in Western Europe. We demonstrate that the results of a variety of typological, technological (especially refitting), and lithological studies have important consequences for our knowledge of the acquisition of raw materials and subsequent production, usage and discard of stone artefacts in the Middle Palaeolithic. Neandertal production and use of stone tools was fragmented in three domains: the spatial, the temporal and the social domain. We show that this versatile segmentation of stone artefact handling strategies is a main determinant of the character of the Neandertal archaeological record. Our data testify to ubiquitous and continuous transport of stone artefacts of a wide variety of forms, picked by Neandertals using selection criteria that were sometimes far removed from what archaeologists have traditionally considered, and to some degree still consider, to be desired end products of knapping activities. The data presented here testify to the variability and versatility of Middle Palaeolithic stone tool technology, whose fragmented character created very heterogeneous archaeological assemblages, usually the product of a wide variety of independent import, use, discard and/or subsequent transport events.     

Les assemblages lithiques des niveaux du Paléolithique moyen de l’Abri des Pêcheurs (Ardèche, Sud-Est de la France): Des occupations néandertaliennes récurrentes dans un « fossé »

The Abri des Pêcheurs has yielded an extraordinary sequence with Middle and Upper Palaeolithic levels. Humans came and stayed in a ditch-cave that has been filled in along time. During Middle Palaeolithic occupations, they used first quartz, and this site is the only case in this area. Assemblages show similar technological behaviour along time. Flint is few employed and arrived as flakes from different areas if we consider its geological variety. Functions of the site are not well established. The base of the sequence has yielded sediments with a mixing of ibex, carnivore bones and artefacts. The study of the lithic assemblages brings information on the processing systems used on quartz and flint during occupations which left few evidence and used local stones while flint is available not far from the site. Hypothesis on short and specialized occupations is discussed.     

Adrenal gland and bone

The adrenal gland synthesizes steroid hormones from the adrenal cortex and catecholamines from the adrenal medulla. Both cortisol and adrenal androgens can have powerful effects on bone. The overproduction of cortisol in Cushing’s disease leads to a dramatic reduction in bone density and an increase risk of fracture. Overproduction of adrenal androgens in congenital adrenal hyperplasia (CAH) leads to marked changes in bone growth and development with early growth acceleration but ultimately a significant reduction in final adult height. The role of more physiological levels of glucocorticoids and androgens on bone metabolism is less clear. Cortisol levels measured in elderly individuals show a weak correlation with measures of bone density and change in bone density over time with a high cortisol level associated with lower bone density and more rapid bone loss. Cortisol levels and the dynamics of cortisol secretion change with age which could also explain some age related changes in bone physiology. It is also now clear that adrenal steroids can be metabolized within bone tissue itself. Local synthesis of cortisol within bone from its inactive precursor cortisone has been demonstrated and the amount of cortisol produced within osteoblasts appears to increase with age. With regard to adrenal androgens there is a dramatic reduction in levels with aging and several studies have examined the impact that restoration of these levels back to those seen in younger individuals has on bone health. Most of these studies show small positive effects in women, not men, but the skeletal sites where benefits are seen varies from study to study.     

The molecular genetics of European ancestry

In an earlier paper we proposed, on the basis of mitochondrial control region variation, that the bulk of modern European mitochondrial DNA(mtDNA) diversity had its roots in the European Upper Palaeolithic. Refining the mtDNA phylogeny and enlarging the sample size both within Europe and the Middle East still support this interpretation and indicate three separate phases of colonization: (i) the Early Upper Palaeolithic about 50,000 BP; (ii) the Late Upper Palaeolithic 11,000-14,000 BP; and (iii) the Neolithic from 8500 BP.     

Age and Date for Early Arrival of the Acheulian in Europe (Barranc de la Boella,la Canonja,Spain)

The first arrivals of hominin populations into Eurasia during the Early Pleistocene are currently considered to have occurred as short and poorly dated biological dispersions. Questions as to the tempo and mode of these early prehistoric settlements have given rise to debates concerning the taxonomic significance of the lithic assemblages, as trace fossils, and the geographical distribution of the technological traditions found in the Lower Palaeolithic record. Here, we report on the Barranc de la Boella site which has yielded a lithic assemblage dating to ∼1 million years ago that includes large cutting tools (LCT). We argue that distinct technological traditions coexisted in the Iberian archaeological repertoires of the late Early Pleistocene age in a similar way to the earliest sub-Saharan African artefact assemblages. These differences between stone tool assemblages may be attributed to the different chronologies of hominin dispersal events. The archaeological record of Barranc de la Boella completes the geographical distribution of LCT assemblages across southern Eurasia during the EMPT (Early-Middle Pleistocene Transition, circa 942 to 641 kyr). Up to now, chronology of the earliest European LCT assemblages is based on the abundant Palaeolithic record found in terrace river sequences which have been dated to the end of the EMPT and later. However, the findings at Barranc de la Boella suggest that early LCT lithic assemblages appeared in the SW of Europe during earlier hominin dispersal episodes before the definitive colonization of temperate Eurasia took place.     

Cueva Negra del Estrecho del Río Quípar: Comings and goings recorded in a late Early (Lower) Pleistocene microstratigraphical palimpsest

Preliminary conclusions from high-resolution microstratigraphical and taphonomical research suggest that Palaeolithic frequentation of the rock-shelter alternated with that of local fauna in the late Early (Lower) Pleistocene.     

Un débitage lamellaire au Proche-Orient vers 40 000 ans cal BP. Le site d’Umm el Tlel,Syrie centrale

Across the Near-East and particularly in Syria, a number of archaeological sites have delivered new industries which can be linked to the intermediate Palaeolithic, more commonly qualified as “Transition industry” Due to the apparition of several facies with new technical orientations, the term of intermediate Palaeolithic seems most appropriate. The bladelets production is one of those innovations. Among the four facies identified in the Palmyra and the El Kowm basins (central Syria), facies 3 and 4 are the most frequent and the best documented in terms of chrono-stratigraphical sequence. Here we present the facies 3 discovered in stratigraphy on the site of Umm el Tlel. This facies has been dated and the industries have been submitted to a micro use-wear analysis. The levels III2a’ and II base’, selected for analysis and dated around 36,000 ± 2500 years (T.L.), are characterized by different modes of production and by various predetermined removals. Among these productions, the bladelets represent more than a third of the predetermined removals. These bladelets have various morphologies and dimensions and result from two modes of production. The first mode consists in alternating Levallois products and bladelets and the second mode utilizes specifics cores. The presence, on all types of bladelets, of micro use-wear corroborates the intentionality of these productions. The use-wear show that the bladelets have been used for various actions in and on different materials worked and that they were maintained according to different modes of prehension. Across the Levant, a technical continuity clearly appears between the facies of the intermediate Palaeolithic and the industries of the upper Palaeolithic: the Ahmarian and the Aurignacian. Nevertheless this technical innovation is integrated in a distinct way according to the considered period. During the intermediate Palaeolithic the lithics productions are different according to the facies and the use of the bladelets is varied. While during the upper Palaeolithic there is a technical normalization of the blanks but also functions of bladelets.
