Lithic technology and social transformations in the South Indian Neolithic: The evidence from Sanganakallu–Kupgal

Here we examine patterns in stone tool technology among Mesolithic, Neolithic and Iron Age localities in the Sanganakallu–Kupgal site complex, Bellary District, Karnataka, South India. Statistical tests are used to compare proportions of raw materials and artefact types, and to compare central tendencies in metric variables taken on flakes and tools. Lithic-related findings support the inference of at least two distinct technological and economic groups at Sanganakallu–Kupgal, a microlith-focused foraging society on the one hand, and on the other, an agricultural society whose lithic technologies centred upon the production of pressure bladelets and dolerite edge-ground axes. Evidence for continuity in lithic technological processes through time may reflect indigenous processes of development, and a degree of continuity from the Mesolithic through to the Neolithic period. Lithic production appears to have become a specialised and spatially segregated activity by the terminal Neolithic and early Iron Age, supporting suggestions for the emergence of an increasingly complex economy and political hierarchy.     

New Neolithic sites in the western al-Hajar mountains

A new archaeological project in the western al-Hajar Mountains in northern Oman involves a systematic survey of the small valley of Qumayrah and excavation of selected sites. Two field seasons revealed a number of Neolithic settlement traces. Three newly discovered sites were excavated, two of which proved to be stratified. The most intensive fieldwork focused on QA 2, a Stone Age campsite that contained stone structures, numerous lithic tools, stone and shell beads and marine shell fragments. Radiocarbon dating provided a c.4200 cal. BC age, corresponding with the prevalent lithic evidence. Two other excavated sites yielded fewer materials, that were, however, diagnostically relevant. They indicate a diachronic occupation ongoing probably since the Late Neolithic till the end of that period, but some materials point to other stages of the Neolithic period as well. The appearance of marine shells suggests seasonal occupation and connections with coastal areas. It raises questions about the reasons for the settling of the Qumayrah valley.     

Mapping Mesolithic and Neolithic cultures behaviours and interactions with nature and properties of rocks in Western France

Multivariate statistical methods are used to study recent Prehistory lithics from the Armorican Massif, allowing us to classify them in more or less distinct groups according to the structural and mineralogical qualities of rock types involved. Analyses are carried out on metamorphic, sedimentary and magmatic rocks making up lithics collected from 31 localities. The petrographic properties are determined by polarizing microscope (POM), while the mechanical properties are obtained by Vickers's indentation method (VI), compression/traction (CT) and ultrasound echography (UE). The results provide us with important information about the management of lithic raw materials used by various human and cultural groups during the Mesolithic and Neolithic of the Armorican Massif. The more commonly used materials show a homogeneous and stable distribution of regional technology styles. The rock types exhibiting mature and homogeneous structures possess the better qualities for knapping (fracture energy G_Ic) and use (edge toughness M₁), and are more involved in exchange. The application of Upward Hierarchical Classification (UHC) and Principal Component Analysis (PCA) allows us to identify the classes of materials as well as the causes of variations of rock type abundance within the lithic assemblages of the Mesolithic and the Neolithic. In this way, we can then also predict the discovery of archaeological artefacts in areas lacking any known indications of the exploitation of outcropping materials.     

Bidirectional blade technology on naviform cores from northern Arabia: New evidence of Arabian-Levantine interactions in the Neolithic

Discovered in March 2015, the sites of DAJ-112 and DAJ-125 in the Al-Jawf province of northern Saudi Arabia consist of a large collection of surface lithic artefacts that can be compared to well-known Pre-Pottery Neolithic (PPN) B technology from the Levant: the two sites include bidirectional blade technology with naviform core preparation and opposed platforms surface exploitation, as well as burin production at a wide scale. Other surface scatters have been identified during the 2013 and 2015 surveys, showing these two sites are not isolated in Al-Jawf, as rather important occurrences of Early Holocene technology have been identified across the region. Although the sites from Al-Jawf are surface occurrences and not radiometrically dated, the finds have proven to be extremely significant, representing a southward incursion of classic naviform cores-based technology, thus expanding the geographical distribution of this technology beyond the Levant. By addressing the lithic evidence from northern Arabia, the expansion and/or influence of PPN populations and cultural elements will be discussed.     

DETECTING AND QUANTIFYING HEAT TREATMENT OF FLINT AND OTHER SILICA ROCKS: A NEW NON‐DESTRUCTIVE METHOD APPLIED TO HEAT‐TREATED FLINT FROM THE NEOLITHIC CHASSEY CULTURE,SOUTHERN FRANCE

Heat treatment of lithic raw material is known from the Middle Stone Age to the Neolithic. These findings require archaeometric techniques and methods for detecting the heat‐induced effects within lithic artefacts. However, the existing methods are often cost‐intensive and time‐consuming, and most of them are destructive. Here, we present a new method using the infrared spectroscopic measurement of the strength of H‐bonds formed between surface silanole groups (SiOH) and H₂O molecules held in open pores of the samples. The reduction of H‐bond strength in chalcedony is shown to be strongly correlated with the loss of open pores induced by heat treatment. Hence, the method is based on measuring one of the transformations aimed for by the instigators of the heat treatment: the reduction of porosity that modifies the rock's mechanical properties. A first application to heat‐treated material from the Neolithic Chassey culture (southern France) shows that flint was heated to temperatures between 200°C and 250°C in this period. This has important implications for the study of the procedures used and the heating environments. Our new method is non‐destructive, rapid, cost‐effective and allows for detection of the used annealing temperatures.     

Polished Stone Axes in Caput Adriae from the Neolithic to the Copper Age

This paper reports the results of a long-term project on the stone axes from Caput Adriae. Available data show that jade axes originating in the western Alps reached the Neolithic groups of Friuli Venezia Giulia and coastal Istria as early as the second half of the 6th millennium BC, during the Danilo/Vla?ka culture. The exchange of this and other classes of lithic artefacts testifies that in this period this area was fully integrated into long-distance exchange systems that used mainly coastal routes. These systems would have continued in the 5th millennium BC, as indicated by a few oversized jade axe blades and other materials. Far from the coast, jade axes entered central Slovenia, probably reaching sites of the Sava Group of the Lengyel culture in the first half of the 5th millennium BC. In roughly the same period, shaft-hole axes made of Bohemian metabasites (BM) spread over central and southeastern Europe, crossed the Alps and reached Italy. According to different Neolithic traditions, during the 5th millennium BC Europe appears to be divided into a jade-using western area and a central-eastern BM-using one. During the 4th millennium BC, the exchange networks of Caput Adriae are increasingly influenced by the eastern Alpine and Balkan world, where the raw material sources of the main groups of shaft-hole axes are located. The association of the rocks used for axe production and copper ore suggests that the changes in raw material exploitation strategies during the Copper Age were probably related to the development of the first metallurgy.     

The Pastoral Neolithic of East Africa

In East Africa, as in many other regions, the initial shift from hunting and gathering to food production was a secondary process involving the introduction of species domesticated elsewhere. Specifically, the East African Neolithic, or Pastoral Neolithic, centered on herding livestock, some of which may have been domesticated in the Sahara and all of which were almost certainly imported from areas to the north. The development of the Pastoral Neolithic was lengthy and complex, having begun before 4000 B.P. and lasted until about 1300 B.P. Although detailed information on this segment of African prehistory is not abundant, data so far available reveal a succession of cultural transformations within the Pastoral Neolithic, such that it can be divided into early, evolved, and late stages, each exhibiting distinctive combinations of ceramic wares, lithic industries, and subsistence regimes. The transformations seem to have been fostered by both environmental change and population movements.     

Early Pig Management in the Zagros Flanks: Reanalysis of the Fauna from Neolithic Jarmo,Northern Iraq

In this paper, we present a reanalysis of pig (Sus scrofa) remains from the Neolithic site of Qalat Jarmo, originally excavated in the 1940s and 1950s. Employing modern zooarchaeological techniques, not available during the initial analyses, we explore the nature of swine exploitation strategies and demonstrate that pigs were most likely managed by the early 7th millennium (Pottery Neolithic) and perhaps earlier. Comparing biometric data with those from other sites in the region, we show that the Jarmo pigs exhibit evidence for size decrease associated with intensive management, but had not yet achieved the degree of dental or post‐cranial size reduction seen in later Neolithic domestic populations. Although samples from the earliest (Pre‐Pottery) occupation of the site are small, there is some evidence to suggest that domestic pigs were present at Jarmo as early as the late 8th millennium cal. bc . In either case, Jarmo likely represents the earliest appearance of pig husbandry along the Zagros flanks, and we discuss the mechanisms by which Neolithic technologies, including domesticated animals, spread to new regions. This project emphasises the value of curated faunal assemblages in shedding new light on the spread of Neolithic economies. Copyright © 2013 John Wiley & Sons, Ltd.     

Identification of ancient starch grains from the tribe Triticeae in the North China Plain

Both macrofossil and microfossil plant remains from the grass family (Poaceae) have been recovered from Neolithic and historic sites in China. Basing our work on the plant taxa that were previously recovered, we analyzed the economically significant genera for modern starch grain analysis with a focus on the important tribe Triticeae. Modern starch grains from the tribe Triticeae were compared with those from other grasses, and criteria for identification were determined. In total, 38 species within 28 genera, 13 tribes and 4 subfamilies were selected for analysis. Results demonstrate that starch grains from members of the tribe Triticeae are discernible from those of other tribes by their distinctive lenticular morphologies and surficial pressure craters. A dichotomous key covering 10 species within 7 genera of the Triticeae was created, thus allowing identification of members of the tribe to the level of genus. Application of the dichotomous key to the ancient starch assemblage recovered from lithic tools excavated from the early Neolithic site of Donghulin demonstrates that plants from the genera Hordeum and Agropyron were exploited alongside millets at this site.     

Recent Prehistoric Field Research in Central Tunisia: Prehistoric Occupations in the Meknassy Basin

Recent field prospection and test excavations in the Meknassy Basin (Central Tunisia) has revealed many prehistoric sites covering almost all the phases of North African prehistory from the Palaeolithic to the Neolithic. Excavations at the Aïn El-Guettar Mousterian site has yielded a faunal assemblage dominated by bovids and equids. One human tooth was found in situ. The stratigraphic sequence contains charcoal-rich occupation layers with faunal, human and lithic finds. A level with an industry resembling the Aterian was found beneath a Mousterian layer. The excavations at Aïn Oum Henda 2 (Jebel Maloussi) provided many Middle Palaeolithic lithic artefacts, some of which are pedunculates. From the excavations of the Rammadiya El Oghrab (Jebel Bou Hedma) we recovered some bones of antelope, many fragments of ostrich egg shell (among them a worked disc), an enormous quantity of flint (tools and splinters) and of land snails. In spite of the scarcity of land snails and the absence of bone in the rammadiya of Jebel Bou Hedma 1, the site produced a beautiful flint collection including an arrowhead found on the surface, which led us to place the site in the Neolithic.     

Were Olduvai Hominins making butchering tools or battering tools? Analysis of a recently excavated lithic assemblage from BK (Bed II,Olduvai Gorge,Tanzania)

A new interpretation of early stone-tool use by hominins at Olduvai depicts them as involved in battering activities (using pounding tools) rather than making cutting butchering tools as is commonly inferred in most other Plio-Pleistocene sites where lithics appear associated to faunal remains. The bulk of this interpretation is based on the recognition of the stigma of percussion activities in anvils and detached by-products. Renewed excavations at BK after more than half a century of the beginning of the digging at the site by M. Leakey have produced a new and unbiased lithic assemblage. The taphonomic study of the faunal assemblage has shown that BK is an anthropogenic site where carcass butchery practices were repeatedly performed over a vast amount of time. The present analysis of the lithic artefacts supports this interpretation by showing that the obtainment of flakes was the principal aim in stone knapping. We argue that a number of technical traits observed in the lithic collection of BK can be best interpreted as the result of bipolar loading rather than the by-products of battering activities. Since BK has provided the second largest collection of hominid-modified bones from Olduvai, it is concluded that detached pieces produced in the course of bipolar reduction might have played an active role in bone modification and that active rather than passive percussion behaviors might have been responsible for the formation of the lithic assemblage. The functionality of the Oldowan stone tools are discussed under the light of the new study.     

Using lithic assemblage formation to approach Middle Palaeolithic settlement dynamics: El Salt Stratigraphic Unit X (Alicante,Spain)

The superposition of anthropogenic remains usually results in archaeological palimpsests, hindering an accurate characterization of the behavior underlying such remains. Aimed at facing this methodological constraint in the study of Palaeolithic contexts, we present a contextual approach to Neanderthal settlement dynamics based on an understanding of lithic assemblage formation processes. We focused on a set of lithic artifacts from the Middle Palaeolithic site of El Salt. With the goal of isolating temporally constrained units of behavioral analysis, we analyzed the spatial distribution of lithic, faunal and combustion remains. Then, the lithic records from each of the resulting units were analyzed from a genetic and technical perspective. This goal was achieved by identifying lithic Raw Material Units (RMU) through observations on reduction processes, refits and their spatial distribution. Our results suggest that El Salt SU X lithic remains represent several diachronic human occupation episodes and different site functions. This study illustrates the benefit of investigating lithic assemblage formation processes to alleviate the palimpsest problem in Palaeolithic contexts.     

Ground penetrating radar survey of a prehistoric site in southern Italy

In this paper, we present and discuss the results of a ground penetrating radar (GPR) study carried out in an area of southern Italy where a karst cave with prehistoric remains was found. The aim of the study involved the imaging of the subsurface stratigraphy, both inside and outside the cave, in order to assist archaeologists in an excavation programme.The survey grid comprised 18 intersecting GPR profiles. Problems associated with the use of the GPR within a cave environment are highlighted and the data processing sequence designed to extract useful geo-archaeological signatures is described. Interpretation of the radar sections was controlled by the excavation of two trenches (inside and outside the cave), allowing detailed outlining the complex stratigraphy and the reconstruction of Palaeolithic and Neolithic subsurface horizons.     

PROVENANCE DETERMINATION OF NEOLITHIC TO CLASSICAL MEDITERRANEAN MARBLES BY STABLE ISOTOPES*

Two stable isotopic data bases for ?¹³C and ?¹⁸O values of marble have been accumulated: (1) 590 analyses from 42 Classical quarries of Greece, western Turkey, Tunisia, and Carrara, Italy, and (2) potential Early Bronze Age (EBA) marble sources in the central Cyclades, comprising 192 analyses from 16 sites on the islands of Paros, Naxos, Ios, and Keros. The data bases include the most important marble occurrences in the eastern Mediterranean and so can be used to source artefacts of any age. Neolithic artefacts found at Franchthi Cave, where no marble occurs locally, have been attributed to the Peloponnese and the Cyclades, direct evidence for early trade. In the Cycladic EBA, Naxos and Keros were the principal marble sources for the abundant artefacts found at Keros. The commercial marble trade in Archaic Greece began in the central Cyclades where the tradition apparently went back some 5000 years, to the Neolithic. Classical Greece and especially Rome expanded the number and locations of commercial marble sources throughout the Mediterranean.     

Application of a new typological approach to classifying denticulate and notched tools: the study of two Mousterian lithic assemblages

Identifying tools by means of morphological attributes are widely used in lithic studies to categorize retouched artifacts from different archaeological periods. This procedure has facilitated the exchange of information between separate researchers and has improved the comparison of different assemblages. In these classifications, denticulates and notched tools have been regularly interpreted as analogues and chronologically unvaried in different and vast territories. Based on the definitions developed by Bordes, the denticulate category has become a catchall for any kind of tool bearing concavities. In this paper a new quantitative approach to the classification of denticulates and notched tools is proposed. The new methodology is based on measuring the length of notches and their distribution on the perimeter of the blank. Analyzing the lithic series of the Abric Romaní rock-shelter (Spain) and Grotta Maggiore di San Bernardino (Italy) led to the identification of 11 redundant forms: eight denticulates and three notched tools. Moreover, the application of Kuhn’s Geometric Index of Unifacial Reduction brought local manufacturing trends to light, calling into question the presumed geographical uniformity of these categories of artifacts.     

Picking up The Pieces: Reconstructing Lithic Production Strategies at a Late Holocene Obsidian Quarry in Southern Kenya

Use of particular lithic quarries by different cultural groups is a prominent feature of the Pastoral Neolithic period in southern Kenya (ca. 3200–1400 b.p.), when lifeways based on herding domesticated livestock spread through eastern Africa. Here, I present lithic attributes from the recently excavated Elmenteitan Obsidian Quarry assemblage to examine the site’s role in an obsidian distribution network spanning southwestern Kenya. Evidence from the quarry reflects intensive preparation of blade cores and blade reduction. Changes in platform size, flake scar orientation, curvature, and cortical rates through the reduction sequence permit a preliminary reconstruction of Elmenteitan core production strategies that can serve as a basis for regional comparative studies. Uniformity in blade core design and reduction strategy suggests highly organized use of the quarry and supports its role as a production center for regional exchange. Results inform regional debates and contribute to a growing literature on the potential of quarry archaeology.     

Defining the provenance of red slipped pottery from Texas and Oklahoma by petrographic methods

Ceramics are among the most important artifacts that archaeologists use to reconstruct patterns of prehistoric trade and exchange. Petrographic analysis of ceramic thin-sections, in addition to providing detailed technological data, enables the identification of sand-tempering agents. These raw materials are potentially important evidence for ceramic provenance, assuming that such common materials themselves would not have been traded. Here we apply methods developed by sedimentary petrographers to the problem of determining the provenance of Red Slipped sherds from late Prehistoric (c. AD 1000–1400) sites in the Caddoan area and contemporaneous Plains Village sites. Modal frequencies of different kinds of quartz, feldspars and lithic grains are used to construct several triangular graphs that reveal compositional patterns indicative of provenance. Sherds from the Plains Village sites exhibit higher frequencies of lithic grains, feldspars and polycrystalline quartz relative to the sherds from sites in eastern Texas and eastern Oklahoma. While anomalous sherds were identified, the longstanding assumption that Red Slipped sherds in Plains Village contexts were traded from the Caddoan area is not supported by these data. These methods have strong application potentials for other, geologically diverse portions of North America.     

Upper Paleolithic raw material economies at Üçağızlı cave, Turkey

This paper addresses variation in lithic raw material economy within the early Upper Paleolithic at Üçağızlı cave (south-central Turkey). The stratigraphic sequence documents some 12,000 years of the early Upper Paleolithic, entailing changes in lithic technology, raw material exploitation, and game use. Although the same lithic raw materials were exploited throughout the sequence to make quite similar ranges of products, there are marked changes in the ways raw materials from different source areas were treated, including patterns of transport and raw material consumption. The concept of technological provisioning is used to understand changing strategies for procuring and managing supplies of flint from different source locations. Shifts in raw material economy are argued to represent responses to changes in residential mobility and the scale/duration of occupations at the cave itself: data on cultural features and foraging strategies provide independent evidence for these shifts in land use. Results have implications for more nuanced approaches to investigating of lithic raw material economies and the significance of “raw material transfers.”     

Carnelian,agate, and other types of chalcedony: the prehistory of Jebel al‐Ma'taradh and its semi‐precious stones,Emirate of Ra's al‐Khaimah

The Jebel al‐Ma'taradh and its surroundings contain exceptional deposits of lithic raw materials, including flint and chert, but especially chalcedony, agate, carnelian, and chrysoprase. These deposits were intensively exploited during the Neolithic, and some of the artefacts produced entered the trade network that included settlements on the coast and inland, sometimes as far as 300 km. During earlier periods, probably as early as the Pleistocene, only flint was used. Between the sixth and the fourth millennia, carnelian and agate were exploited to make beads, which are found in the necropolises and settlements of the UAE.
