An Archaeological Study of Early Farming Settlements on Iresi Hills

Recent Investigation of an archaeological site in southwest Nigeria during the Late Stone Age revealed additional information about the cultural development of the area. On Iresi Hills two rock shelters (Ajaye and Cherubim & Seraphim) were investigated in two seasons from 2017 to 2018 during which pottery, ground stone axes and microlithics were excavated. Although there is no clear break in the stratigraphy, the findings show clear demarcation between two cultural layers. The upper layer contains pottery, microlithics and ground stone axes, and ochre while the lower layer is characterized by microlithics only. The site presented a date of about Cal 5653 BP which coincides with a short dry period in the area. Tis paper reports the occupation in Iresi, in southwest Nigeria with a view to fill the gap in the chronology and to interrogate the evidence for Late Stone Age in terms of the culture that existed in between 12000YBP of Iwo Eleru and 2000YBP of Itaakpa and the influence of a change in environment of southwest Nigeria and West Africa in general.

The West African Stone Age

In terms of artefacts present, West Africa is not short of evidence relating to human occupation during the Quaternary. The problem hitherto has been one of context and dating; there has been some progress in this regard but poor preservation conditions still restrict the presence of organic remains prior to the beginning of the Late Stone Age (LSA). Nonetheless, an excellent climatic record for the last 520 kya has been established on the basis of cores obtained from Lake Bosumtwi. Stratified Acheulean sites have been excavated at Sansandé and Ravin Blanc on the Falémé River in eastern Senegal. The succeeding Sangoan is an entity for which a consistent and reliable classification remains to be achieved. Despite this, excavations at Anyama in the Ivory Coast have produced a sizeable quantity of material, with a terminus post quem thermoluminescence (TL) date of 254 ± 51 kya. Our knowledge of the Middle Stone Age (MSA) has been transformed by the work carried out at Ounjougou in Mali. More than twenty-five distinct archaeological occurrences have been detected, extending from about 75 to 25 kya. The MSA elsewhere is abundant, and at Adrar Bous is in place beneath the Aterian, but much of it lacks a good stratigraphic context. The following dry period, the Ogolian, must have had a dramatic effect on human settlement, and the majority of LSA sites postdate this episode. There is no apparent link between them and the MSA. Nonetheless, the LSA at Shum Lake in Cameroon does have 14C dates in the range 32,700–12,800 BP. The most significant LSA site is Iwo Eleru, notable for the presence of modern human remains with “archaic” characteristics. A parallel situation has been detected at Ishango in the eastern Democratic Republic of Congo both indicating a hitherto unsuspected “deep substructure” in Late Pleistocene African populations.

The Shell Midden Sites of Senegambia

There are hundreds of shell midden sites along the Senegambian coastline. The shell middens were first formed during an eustatic event known as the Nouakchottien marine transgression (6,800–4,000 bp). During that marine transgression, the sea shoreline was pushed back hundreds of miles in the interior. This engendered the flourishing of malacological fauna and several fish species. As a result of this, several natural shell midden were formed. From the Late Stone Age to the 2nd millennium ce, populations exploited the aquatic fauna, which resulted in the formation of anthropogenic shell middens. The littoral where these shell middens are found is divided into three archaeological culture areas. Archaeological excavations at some of those sites, such as Khant and Dioron Boumak, have shed light on the nature of the material culture, subsistence activities, and the cultural history in these areas. Research at Soukouta has added new data on iron technology to understanding of the shell middens culture. These findings have also called into question the division of Senegambian prehistory into four distinct cultural areas known as aires culturelles.

A Southern African Perspective on the Contribution of Charcoal Analyses to Archaeology

Southern Africa has a long and rich archaeological record, ranging from the Oldowan lithics in the Sterkfontein valley and Wonderwerk Cave (about 2 Ma) to Iron Age smelting (less than one thousand years ago) in Zimbabwe. A brief overview of charcoal analyses indicates applications in such areas as dating, vegetation and climate reconstructions, fuel use, medicinal use, and the interpretation of human behavior. Some of the research done in the 20th century mainly focused on charcoal for the purpose of dating, but this has diversified in the 21st century to include other applications. The focus is on South African sites, but research from Botswana, Lesotho, Swaziland, and Zimbabwe is included. Southern Africa has a very diverse woody component with more than fifteen hundred species from a flora of more than twenty-five thousand species so the establishment of regional modern reference collections of charcoalified woods has been instrumental in improving identifications of the archaeological taxa. Early Middle Stone Age charcoal records show that a diversity of woody species was burned. By Middle Stone Age times, records show the selection of woods for fuel, tinder, and medicinal use as well as cooking of starchy rhizomes. Late Stone Age and Iron Age records, in addition, show the use of woods for smelting and intense fires.

Archaeology of Botswana

The prehistory of Botswana concerns the sophisticated environmental knowledge, economic strategies, and social networks of the hunter-gatherer, pastoralists, and agropastoralist communities that have called Botswana home. Diverse subsistence strategies and societal structures ranging from heterarchical to hierarchical have coincided and responded flexibly to climate and environmental variables. Botswana has also played a central, but often overlooked, role in precolonial trade within the interior of Africa and across the Indian Ocean. Botswana contains well-preserved archaeological records for the Middle Stone Age, Late Stone Age, and Iron Age periods, including one of the highest concentrations of rock art in the world at Tsodilo Hills. The prehistory of Botswana extends over 100,000 years and includes successful, innovative, and adaptive occupations in a wide variety of environmental zones, from the Okavango Delta to the Kalahari sandveld, and better-watered hardveld areas in the east. Stone Age peoples adapted to both arid and wet lands, and the archaeological record includes early evidence for freshwater fish exploitation. Hunting with bone points dates to 35,000 years ago, with additional evidence for poisonous, reversible arrowheads between 21,000 and 30,000 years ago. Evidence for ritualized behavior through rock paintings, rock carvings, and the intentional destruction and abandonment of stone tools at Tsodilo Hills provides further insights to the social dimensions of early peoples. In the Iron Age, hunter-gatherer communities and agropastoralists participated in a regional and later protoglobal trade across the Indian Ocean for a thousand years before European involvement; as the regional economy intensified, large polities such as Bosutswe and even kingdoms such as the Butua state emerged, controlling access to resources such as game, ivory, salt, specularite, and gold. In the modern era, the historical archaeology of sites such as Old Palapye (Phalatswe) provide additional insight to historical documents that can contradict Eurocentric understandings of Botswana’s past.

New data about the Orlovskaya culture household in the steppe Volga region

Researchers suggest a hypothesis that one of the indicators of the Neolithic is settlements based on stable fishing using boats and nets. The northern part of the Lower Volga region is a steppe zone. The peculiarities of natural and climatic conditions (arid climate, a small number of rivers) predetermined a low population density in comparison with other regions. The location of long-term camps is traced on different rivers on particular distance from each other. This provided normal conditions for life of the Orlovskaya culture representatives. The culture stratification in loam leaded to good preservation of faunal remains. The big archeozoological material was accumulated for reconstruction of these societies household. Hunting was carried out mainly on large ungulates. In addition, waterfowl accounted for a significant proportion. A domestic dog provided assistance in hunting. Finds of bone harpoons and hooks, accumulations of scales and bones of pike and perch are speaking about individual fishing. Stone sinkers, axes and adzes, vertebrae may suggest fishing with a net from a boat or a raft. The absence of sturgeon remains give a thought that the Bolshoi Uzen River didnt flow into the Caspian Sea in the Late Stone Age.

Archaeology in the Public Space in Nigeria

Nigeria, with over 200 million people, covers an area of 923,768 km2 and it occupies the eastern section of the West African region (Figure 1). The regions of Nigeria have prehistoric sites spanning from the Early Stone Age through the Middle Stone Age, the Late Stone Age/Neolithic to the Iron Age and the beginning of urbanization. Several historic empires, states and polities developed within the geographical area now occupied by Nigeria and had left archaeological relics.

The History of Gabon

Primeval rainforest at the Equator on the west coast of Africa, the land we know as Gabon, was settled prehistorically by Pygmies during the late Stone Age, and then by Bantu-speaking migrants during the Iron Age. These culturally diverse peoples did not develop a common language or political system with one another until after their violent conquest by Europeans during the colonial era. The Age of Discovery in the 15th century brought European explorers to the coast. The Atlantic triangle trade, with its slave barracoons and entrepôts, transformed some African communities along the coast into centralized kingdoms, and turned other clan-based societies of the forested interior into hunted peoples suspicious of any and all outsiders, European or African. The Scramble for Africa brought military expeditions into Gabon in the 19th century, when French colonial rule was established. Colonialism bestowed on the ethnic groups of Gabon a protonational identity of being “Gabonese,” although this nationalist impulse was muted in the late 19th and early 20th centuries by the effort of French authorities and missionaries to assimilate black Africans into France’s culture and civilization. Unassimilated colonial subjects in the interior of the newly conquered territory violently resisted French colonial rule until the world wars, by which time the assimilation project had sufficiently fashioned a new coastal French-educated Gabonese elite. The two world wars weakened France and led these assimilated elites to a call for political reforms, at first taking the form of mono-ethnic-based political parties, but eventually coalescing around multiethnic coalitions, largely francophone in outlook, while retaining many elements of older precolonial identities. Independence in 1960 brought to power three authoritarian rulers—Léon Mba, Omar Bongo, and Ali Bongo—as well as consolidation of an oil-rentier state and an oxymoronic dynastic republic. “Gabonese” national identity emerged, an imagined community constructed out of African music, literature, and art, yet incorporating French as its lingua franca.

New data on settlement and environment at the Pleistocene/Holocene boundary in Sudano-Sahelian West Africa: Interdisciplinary investigation at Fatandi V, Eastern Senegal

The end of the Palaeolithic represents one of the least-known periods in the history of western Africa, both in terms of its chronology and the identification of cultural assemblages entities based on the typo-technical analyses of its industries. In this context, the site of Fatandi V offers new data to discuss the cultural pattern during the Late Stone Age in western Africa. Stratigraphic, taphonomical and sedimentological analyses show the succession of three sedimentary units. Several concentrations with rich lithic material were recognized. An in situ occupation, composed of bladelets, segments, and bladelet and flake cores, is confirmed while others concentrations of lithic materials have been more or less disturbed by erosion and pedogenic post-depositional processes. The sequence is well-dated from 12 convergent OSL dates. Thanks to the dating of the stratigraphic units and an OSL date from the layer (11,300–9,200 BCE [13.3–11.2 ka at 68%, 14.3–10.3 ka at 95%]), the artefacts are dated to the end of Pleistocene or Early Holocene. Palaeoenvironmental data suggest that the settlement took place within a mosaic environment and more precisely at the transition between the open landscape of savanna on the glacis and the plateau, and the increasingly densely-wooded alluvial corridor. These humid areas must have been particularly attractive during the dry season by virtue of their rich resources (raw materials, water, trees, and bushes). The Fatandi V site constitutes the first stratified site of the Pleistocene/Holocene boundary in Senegal with both precise geochronological and palaeoenvironmental data. It complements perfectly the data already obtained in Mali and in the rest of western Africa, and thus constitutes a reference point for this period. In any case, the assemblage of Fatandi V, with its bladelets and segments and in the absence of ceramics and grinding material, fits with a cultural group using exclusively geometric armatures which strongly differs from another group characterized by the production of bifacial armatures, accompanied in its initial phase by ceramics (or stoneware) and grinding material.
