Imperial Expansion, Ethnic Change, and Ceramic Traditions in The Southern Chad Basin: A Terminal Nineteenth-Century Pottery Assemblage from Dikwa, Borno State, Nigeria

In the course of an archaeological project in the southern Chad Basin of Nigeria, excavations were conducted at several deeply stratified mound sites that date from the Late Neolithic to the Late Iron Age. As a way to complement the ceramic sequence obtained so far and to link it with today's pottery tradition, a small excavation was conducted at a site that dates to the turn of the nineteenth to the twentieth century A.D. A pottery assemblage was discovered that shows obvious links to today's tradition but notable breaks with those of the nineteenth century and earlier. This break in decoration style and technique is interpreted as an archaeologically visible expression of changing ethnic identity. This ethnic change and the associated spread of the ceramic tradition can be linked with the expansion of the sphere of power of the Kanem-Borno Empire into the area south of Lake Chad after the sixteenth century A.D.     

The fish of Lake Titicaca: implications for archaeology and changing ecology through stable isotope analysis

Research on past human diets in the southern Lake Titicaca Basin has directed us to investigate the carbon and nitrogen stable isotopes of an important dietary element, fish. By completing a range of analyses on modern and archaeological fish remains, we contribute to two related issues regarding the application of stable isotope analysis of archaeological fish remains and in turn their place within human diet. The first issue is the potential carbon and nitrogen isotope values of prehistoric fish (and how these would impact human dietary isotopic data), and the second is the observed changes in the fish isotopes through time. Out of this work we provide quantitative isotope relationships between fish tissues with and without lipid extraction, and a qualitative analysis of the isotopic relationships between fish tissues, allowing archaeologists to understand these relationships and how these values can be applied in future research. We test a mathematical lipid normalization equation to examine whether future researchers will need to perform lipid extraction procedures for Lake Titicaca fish. We also analyze a number of aquatic plants to better understand the range of isotopic signatures of the Lake Titicaca ecosystem. We use these data to better understand prehistoric human diet and the role that fish may have played in the past as well as potential changes in local lake ecology through time.     

Garu Kime: A Late Borno Fired-Brick Site at Monguno,NE Nigeria

Abstract  

This paper primarily presents analyses from geophysical data and archaeological remains collected at one of a few known sites to the west of Lake Chad associated with fired-brick structures. It reports on previous fieldwork at the location, considers its alleged relationship with the early history of the Borno kingdom and then turns to present new data that provide fresh insights into the physical appearance, dating, material remains, economy and environment of the site. A brief discussion of the historical purpose of the fired-brick structures and the site itself concludes the paper.     

Ancient Humped Cattle in Africa: A View from the Chad Basin

The origins of ancient and modern African cattle are still a matter of much debate among researchers. Part of the dispute involves the question of the appearance in Africa, from the second millennium BC onwards, of cattle carrying a distinguishing morphological feature present in most of the modern sub-Saharan breeds: The hump. This paper addresses the issue of the origins of the African humped cattle. After reviewing the current hypothesis on their origins, the status and significance of old and new archaeological and osteological evidence from the Chad Basin are presented and critically discussed. Mainly based on the cultural context of the archaeological figurative evidence available in the remaining continent, a case for the foreign ancestry of the ancient African humped cattle is made, and a perspective for future research in the topic is provided.     

An Early Bronze Age Logboat from Degersee, Southern Germany

In 2004 the remains of a logboat were discovered in Degersee, a small lake near Lake Constance, southern Germany. Dating to the beginning of the 2nd millennium BC, it is an important find from a period with scarce archaeological evidence and only a few previously-known logboats. The vessel was situated in lake sediment and documented in situ . Our investigations can be linked to palaeo-environmental studies carried out at Degersee and adjacent lakes, and to palaeo-climatic research in the northern Alpine region. After investigation by underwater archaeologists the boat was moved to a sheltered place in deeper water.

Wild or domesticated? An ancient DNA approach to canid species identification in South Africa's Western Cape Province

The fragmentary remains typical of archaeological fauna can prove impossible to identify when confronted with closely related sympatric species. In southern Africa domesticated dogs (Canis familiaris) and black-backed jackals (Canis mesomelas) pose just such a problem, rendering difficult an accurate assessment of the timing of arrival of domesticated dogs in the region. Contextual evidence has suggested that canid remains from four Later Stone Age archaeological sites were likely to be domesticated dogs rather than jackals, and were subjected to ancient DNA analyses to determine species. Every tested specimen proved to derive from black-backed jackals. These data provide not only an unexpected window on southern African prehistory, but also highlight the value in applying ancient DNA techniques to archaeological species identification.     

Through the Glass Darkly: Prehispanic Obsidian Procurement and Exchange in Southern Peru and Northern Bolivia

Recent discovery of the major geological sources of Central Andean obsidian permits a new understanding of the patterns of obsidian procurement and exchange by the Prehispanic societies of southern Peru and northern Bolivia. Based on the trace element analysis of obsidian artifacts from 160 archaeological sites, it can be established that the two major deposits of obsidian were being exploited by 9400 BP, and that volcanic glass was being transported over long distances throughout Andean prehistory. Inhabitants of the Cuzco region acquired most obsidian from the Alca source in central Arequipa, while those in the high plateau surrounding Lake Titicaca obtained most obsidian from the Chivay source in southern Arequipa. Obsidian evidence suggests close ties between the Cuzco and Circum-Titicaca regions throughout prehistory, except during the Middle Horizon (ca. 1400–1050 BP), when the expansion of the Huari and Tiahuanaco states disrupted this pattern.     

THE EARLY IRON AGE IN THE PARIS BASIN: A STUDY IN CULTURE CHANGE

Summary. The archaeological evidence for Iron Age cultures in the Paris Basin is outlined. The data are heavily weighted to burials, there being little evidence available of settlements, but regional patterns of variation can be recognized. The broader contacts of the region are discussed and the effects of external trade and internally generated pressures on socio-economic systems are considered.     

Quebrada Tacahuay,Southern Peru: A Late Pleistocene Site Preserved by a Debris Flow

Abstract

Here we describe the properties of a debris flow apparently generated by a warm phase El Niño event that buried an intermittently occupied Late Pleistocene forager site located in the southern coastal desert of Peru. Although the event deposited roughly one meter of sediment over the initial occupation, our analyses of debris flow dynamics and data from large scale archaeological investigations indicate that the earliest anthropogenic deposits at the site of Quebrada Tacahuay were preserved intact as a result of the burial episode; there is no evidence that the debris flow scoured or disturbed the cultural deposits. The event that buried the oldest archaeological contexts at Quebrada Tacahuay differs from other flood events that are characterized by turbulent, fast-moving floodwaters. Our data on debris flow dynamics and our results from excavation have implications for identifying, investigating, and interpreting other deeply buried archaeological sites both in the central Andes and in other geographic regions.     

Garumele Revisited: Retracing Vanished Fired-Brick Elite Constructions and New Data on Settlement Foundation

Some of the most notable and largely endangered archaeological remains from the Lake Chad area consist of the ruins of fired-brick elite constructions connected to the Kanem-Borno Empire (ca. eighth–nineteenth century AD). In the course of the last 200 years, several of the elite structures known west of the lake were destroyed as a consequence of war, later having their fired-bricks looted for constructions elsewhere. One of the largest and most thoroughly plundered of those structures once stood within the walled settlement of Garumele, SW Niger Republic. In the scope of an experimental field study at that location and with a view to future work at related sites, we demonstrate that it is still possible to retrace the ground plans of Kanem-Borno fired-brick structures, even if these have been already completely pillaged. In addition, we present new chronological evidence suggesting that Garumele—as a walled urban settlement—was founded sometime between the mid-fifteenth and mid-seventeenth centuries, but most probably between the late sixteenth to mid-seventeenth centuries AD.     

Late Holocene climatic fluctuations and soil genesis in southern Patagonia: effects on the archaeological record

Geoarchaeological research conducted at five localities in southern Patagonia and Tierra del Fuego identified a mollisol within late Holocene aeolian and colluvial deposits associated with archaeological material. The mollisol's origin and development are related to an increase in humidity (c. 1000 BP) following an episode of severe drought during the Medieval Warm Period. Corroborating data is supplied from dendroclimatic and pollen studies. A drastic reduction in frequency of artefact distribution recorded at the sites studied corresponds to this pedologic event, suggesting a greater human presence at these sites during earlier, regional-scale arid conditions. However, the paucity of archaeological remains may also be the result of the low resolution of cultural evidence following the pedologic development due to superimposition over previous archaeological deposits.     

Pollen-Analytical Results from Lake Katajajärvi – Aspects of the History of Settlement in the Finnish Inland Regions

Abstract

The Early Metal Period (1800 cal BC–AD 300) of the Finnish inland regions is characterized by a scarcity of archaeological remains. Its latest stages, in particular, have proved to be difficult to interpret. This paper discusses the continuity of settlement in the Early Metal Period as indicated by archaeological survey and pollen-analytical data. The study area is situated in Repovesi National Park in southeastern Finland. The pollen analysis was constructed from a sediment sequence taken from Lake Katajajärvi. The archaeological survey data from Repovesi National Park supports earlier hypotheses of the small number of Early Metal Period sites. In the pollen data, the first anthropogenic impact is recorded from about 2600 BC onwards, with weak signs of cultivation around 2370 BC. From around 1900 BC onwards a clear change in tree, shrub and herb pollen percentages indicates anthropogenic impact, possibly grazing, in the area. The pollen-analytical results also revealed a cultivation period of about 900 years at the end of the Early Metal Period, providing proof of continuity in settlement during a period characterized by a scarcity of archaeological material. A new beginning of cultivation from cal AD 1160 to 1250 onwards can be considered as indicating population growth, developing settlements and the colonization of new areas. The results from Repovesi are challenging from an archaeological point of view, because they represent slash-and-burn cultivation that appears to have been practised in total wilderness conditions. Comparison of the Lake Katajajärvi results with other areas raises new questions that call for a discussion of early slash-and-burn cultivation in new perspective.     

Macusani obsidian from southern Peru: A characterization of its elemental composition with a demonstration of its ancient use

Transparent obsidian artifacts have been reported for the northern Lake Titicaca Basin. Based on instrumental neutron activation analysis (INAA) of these artifacts a distinct chemical group was identified. Yet, the location of the source of transparent obsidian in the southern Andes remained unreported in the archaeological literature. This paper reports on the chemical composition and geographic location of a source of transparent obsidian from the Macusani region of Peru. Through the use of INAA and portable X-ray fluorescence (PXRF) we demonstrate that Macusani obsidian or macusanite comprises (at least) two chemical groups. One of these groups was used for making artifacts during the Archaic Period. Artifacts made of this obsidian were found more than 120 km from the source and yet, one-third of the obsidian artifacts encountered at Macusani were from the non-local source of Chivay which is 215 km to the southwest.     

Genes, language, and culture: an example from the tarim basin

Summary. The Tarim Basin ‘mummies’ of western China continue to fascinate scholars and the general public alike due to their ‘Caucasoid’ features, well‐preserved material culture, and putative ‘European’ origins. However, there have been some uncritical efforts to link these archaeological cultures to those of other ancient Eurasian groups (e.g. the Celts) by applying syllogistic reasoning to multi‐disciplinary evidence. In an attempt to provide a more cautious synthesis of the prehistory of the Tarim Basin, this paper will briefly summarize the archaeological, physical, and linguistic evidence that has been used to model human settlement of this region. These data will then be related to recent molecular anthropology research on modern populations of Central Asia, focusing especially on the Uighur in relation to their neighbours. While the genetic history of the modern peoples of a particular region is not necessarily related to their prehistoric antecedents, it is argued that the Tarim Basin experienced a surprising cultural and biological continuity despite immigration from both east and west into Xinjiang Province. This conclusion has a number of possible political ramifications in the present day that must be addressed in future literature on the subject.     

A Syndetic Approach to Identification of the Historic Mission Site of San Cayetano del Tumacácori

This article explores the methodological considerations of a syndetic approach to archaeological inquiry. This multi-evidential approach involves crossing interdisciplinary boundaries to exploit data that reside with other specialists. The material evidence of a historically referenced place is sought in the archaeological record and evaluated using historical documentary data, ethnographic information, as well as data from other sources including assessment of occupational duration, intensity of residence, erosional patterns, and chronological placement. The case study involves location and verification of the 1690s through 1750s Sobaípuri-O’odham village of San Cayetano del Tumacácori in southern Arizona.     

Population Estimates from Settlement Area and Number of Residences

Abstract

Using modern data from the Lake Patzcuaro Basin in Mexico, the author evaluates in this paper the correlations between settlement areas and populations in order to assess the possibilities of estimating the size of prehistoric populations on the basis of the extent of occupation areas. The relationship between number of residences and population is similarly explored. Predictions within the defined categories are accurate in nearly two-thirds of the cases. This result suggests that the method has some value for estimating populations in archaeological situations where the required continuity of patterns of residence assures the relevance of historical data.     

PROVENANCE STUDIES OF CHALCOLITHIC OBSIDIAN ARTEFACTS FROM NEAR LAKE URMIA, NORTHWESTERN IRAN USING WDXRF ANALYSIS

In 2005–2006 we initiated a major archaeological survey and chemical characterization study to investigate the long-term use of obsidian along the eastern shores of Lake Urmia, northwestern Iran. Previous research in the area suggested that almost all archaeological obsidian found in this area originated from the Nemrut Daĝ source located in the Lake Van region of Anatolia (Turkey). More recent research on obsidian artefacts from the Lake Urmia region has identified a significant number of obsidian artefacts with compositions different from the sources near Lake Van. This suggests that the obsidian artefacts are from a yet to be identified geological source, but possibly one that was not too distant. In order to advance our knowledge of Iranian obsidians and eventually refine provenance criteria we analysed obsidian from 22 Chalcolithic sites and some source areas. The compositions of both obsidian source samples and artefacts were determined using wave length dispersive X-ray fluorescence spectrometry (WDXRF). This paper presents results from the trace elemental analysis of both geological and archaeological obsidians, providing important new data concerning the diachronic relationship between lithic technology and raw material in the north-west of Iran.     

Ancient social landscapes of northwestern Argentina: preliminary results of an integrated approach to obsidian and ceramic provenance

This article presents the results of ongoing instrumental neutron activation analyses (INAA) conducted on archaeological artifacts from the Formative period of northwestern Argentina (NWA). These studies are part of a wider archaeological project that seeks to understand the structure of the social landscape of the period by examining domestic and burial evidence from a wide range of villages across the area known as the southern Calchaquí valleys. Elemental data is discussed in the light of its potential contribution to reassess past social interaction strategies in the region.     

The Precontact Iroquoian Occupation of Southern Ontario

Iroquoians become recognizable in the archaeological record of southern Ontario about A.D. 500, with the appearance of Princess Point sites and maize agriculture in the lower Grand River valley. After A.D. 1000, Iroquoians lived in longhouse villages situated in the interior, north of Lake Erie, Lake Ontario, and the St. Lawrence River. This synthesis of the Iroquoian occupation of southern Ontario prior to European contact focuses on origins, settlement patterns, demography, subsistence, and sociopolitical organization. It highlights the significant contributions to Iroquoian archaeology that have been made by government and private consulting archaeologists over the last two decades.     

Provisioning Inka feasts at Tiwanaku, Bolivia: the geographic origins of camelids in the Pumapunku complex

While political integration can be achieved by many means, here we focus on the use of feasting and statecraft in the Inka Empire of the Andean Late Horizon (c. AD 1400-1532) in South America. In order to examine Inka political integration of the Lake Titicaca Basin of Bolivia, we examine paleomobility and paleodiet through radiogenic strontium and stable oxygen and carbon isotope data in archaeological camelid remains from the site of Tiwanaku. Mean radiogenic strontium isotope values from all archaeological camelid enamel and bone samples is ⁸⁷Sr/⁸⁶Sr = 0.70998 ± 0.00179 (1σ, n = 48), mean stable oxygen isotope values from a sub-set of archaeological camelid enamel and bone samples is δ¹⁸O_{carbonate (VPDB)} = −10.0‰ ± 2.6‰ (1σ, n = 18) and mean stable carbon isotope values from a sub-set of archaeological camelid enamel and bone samples is δ¹³C_{carbonate (VPDB)} = −9.0‰ ± 1.7‰ (1σ, n = 18). While many camelids consumed in these feasting events were likely local to the Lake Titicaca Basin, others came from a variety of different geologic zones, elucidating our understanding of Inka statecraft and the role of feasting in political integration in empires in the past.
