Kariandusi: Acheulean morphology and the question of allometry

Allometry, or size-related variation, is shown to be an important factor in the bifaces of two separate assemblages from the Acheulean site of Kariandusi in Kenya. Such variation has functional and possibly stylistic implications. The paper gives a review of the archaeology of Kariandusi, and then investigates the question of size and shape variation in bifaces. The Upper Sites at Kariandusi, first investigated by L. S. B. Leakey, have yielded many obsidian bifaces which can be dated to approximately 0.7–1.0 myr ago. Material from the Lower Site, including many lava bifaces, is judged to be stratigraphically younger but probably in the same time range. We show by making comparisons with the neighbouring Acheulean sites of Kilombe and the Kapthurin Formation that allometry is present in biface assemblages at least 0.5 myr different in date; that similar principles of allometry operate in all the assemblages; and that where there are differences of allometric pattern, within-site variation is sometimes greater than variation between distant sites. We conclude that the size of a biface at least partly determines the shape in which it was made, and that sites in the time range ofHomo erectus and earlyHomo sapiens show surprisingly similar allometric patterns.

Résumé Il est démontré que l'allométrie ou variation dimensionnelle, est un facteur important des bifaces de deux collections séparées du site acheuléen de Kariandusi au Kénya. Une telle variation a des implications fonctionnelles et peut-être aussi stylistiques. Cet article examine l'archéologie de Kariandusi, puis étudie la question des variations de dimensions et de formes dans les bifaces. Les sites plus élevés de Kariandusi, que L.S.B. Leakey a été le premier à fouiller, ont donné de nombreux bifaces d'obsidienne que l'on peut dater d'environ 0,7–1,0 million d'années. Le matériel obtenu dans le site inférieur, y compris de nombreux bifaces en lave, est jugé plus récent stratigraphiquement, mais probablement de la même période. En faisant des comparaisons avec les sites acheuléens voisins de Kilombe et de la Formation Kapthurine, nous démontrons que l'allométrie est présente dans des collections de bifaces dont les dates diffèrent d'au moins 0,5 million d'années; que des principes d'allométrie similaires s'appliquent à toutes les collections; et que lorsqu'il y a des différences de schéma allométrique, la variation au sein d'un même site est souvent plus importante que la variation entre des sites distants. Nous concluons que la dimension d'un biface détermine au moins partiellement sa forme, et que les sites de la période de l'Homo erectus et du début de la période de l'Homo sapiens présentent des schémas allométriques étonamment semblables.

     

The oldest handaxes in Europe: fact or artefact?

Hominin presence is well documented in a number of Early Pleistocene and early Middle Pleistocene European localities. However, the evidence currently available indicates that Acheulean handaxes spread in the fluvial basins of Western Europe during MIS 11, ～400 kyr ago, associated with Homo heidelbergensis, although a number of early Middle Pleistocene Acheulean assemblages have been dated from MIS 16 onwards. For this reason, the magnetostratigraphic dating in Southeast Spain of two archaeological localities, the open-air site of Solana del Zamborino (SZ) and the rock-shelter site of Cueva Negra del Estrecho del Quípar (EQ), that put back the appearance of handaxes to the Early-Middle Pleistocene limit (Scott and Gibert, 2009) is of particular interest, as the new ages suggest that H. heidelbergensis was a contemporary of H. antecessor that had the ability to produce Levallois debitage and to control fire during the Early-Middle Pleistocene transition. However, we have detected a number of errors in the interpretation of the archaeological assemblage from the first site as well as striking discrepancies with the original faunal lists published for both localities, with several large mammal species that are omitted or arbitrarily changed to make the assemblages consistent with the new ages deduced from magnetostratigraphy. For this reason, we suggest that: (1) the finding of reverse polarity in the sediments sampled for paleomagnetism in SZ may simply record one of the polarity reversals that took place during the Brunhes Chron, although the use by Scott and Gibert (2009) of a composite stratigraphic column precludes correlating these levels with a specific reversal; and (2) the fauna and tools of EQ correspond to the late Middle Pleistocene sedimentary infillings of this karst site, while the samples taken for paleomagnetism belong to a previous sedimentary cycle during the Matuyama Chron. Such interpretations would be in better agreement with the age estimates provided by biostratigraphy and also with the currently accepted chronology for the appearance of Acheulean industries in Western Europe.     

Mounds,Towns, and their Surrounds: An Archaeological,Historical, and Geophysical Approach to Burial Mounds,Residential Space,and Cultural Landscapes of the Late Woodland Springwells Site (a.d. 800–1400) at Historic Fort Wayne,Detroit

Historic Fort Wayne is located on the Detroit River in a landscape of heavy industry and marginalized urban neighborhoods (figure 1). Geophysical survey south of the Fort Wayne Mound—a Late Woodland Period burial mound enclosed by the Fort—indicates that pre-contact residential structures may be preserved at the site. Residential sites with mortuary monuments are uncommon in southeastern Michigan and represent an opportunity to better understand variation in Late Woodland settlement. Our approach combines existing archaeological research, historical records, and non-invasive geophysical survey in a culturally sensitive Native American site context presently unavailable for conventional archaeological excavation. We examine archaeological and historical records from Springwells and Late Woodland period settlements in the region to contextualize geophysical evidence from the site. The research prioritizes protection of Native American heritage sites in urban contexts together with ongoing archaeological interpretation of the Late Woodland cultural Landscape.     

New radiometric ages for the Fauresmith industry from Kathu Pan,southern Africa: Implications for the Earlier to Middle Stone Age transition

The Fauresmith lithic industry of South Africa has been described as transitional between the Earlier and Middle Stone Age. However, radiometric ages for this industry are inadequate. Here we present a minimum OSL age of 464 ± 47 kyr and a combined U-series–ESR age of 542₋₁₀₇⁺¹⁴⁰ kyr for an in situ Fauresmith assemblage, and three OSL ages for overlying Middle and Later Stone Age strata, from the site of Kathu Pan 1 (Northern Cape Province, South Africa). These ages are discussed in relation to the available lithostratigraphy, faunal and lithic assemblages from this site. The results indicate that the Kathu Pan 1 Fauresmith assemblage predates transitional industries from other parts of Africa e.g. Sangoan, as well as the end of the Acheulean in southern Africa. The presence of blades, in the dated Fauresmith assemblages from Kathu Pan 1 generally considered a feature of modern human behaviour ( McBrearty and Brooks, 2000, The revolution that wasn't: a new interpretation of the origin of modern human behavior, J. Human Evolution 39, 453–563),-provides evidence supporting the position that blade production in southern Africa predated the Middle Stone Age and the advent of modern Homo sapiens.     

Flakes Crossing the Straits? <Emphasis Type="Italic">Entame</Emphasis> Flakes and Northern Africa–Iberia Contact During the Acheulean

The entame core method was defined after studying the Acheulean bifaces from the site of Ternifine, Algeria. This specialized core method for the production of larges flakes (>10 cm) used for biface blanks involves the detachment of primary large flakes from skillfully selected quartzite cobbles. While technologically simple, a competent selection of raw material and dexterous detachment of the flake resulted in a blank perfectly suitable for the production of bifaces, with minimal further shaping required. This core method resulted in high frequencies of entame blanks in the Ternifine lithic assemblages, as well as from the Iberian Peninsula Acheulean, but not in assemblages from other large flake Acheulean sites. It is suggested that the frequent use of the entame core method common to both North Africa and the Iberian Peninsula indicates similarity in lithic tradition during the Acheulean. This may support the view of North African origin for the Iberian Acheulean during the Middle Pleistocene.     

The Transition to the Acheulean in East Africa: an Assessment of Paradigms and Evidence from Olduvai Gorge (Tanzania)

The origin of the Acheulean constitutes a key aspect of current research in the archaeology of human evolution. Olduvai Gorge is one of the main sites in Africa in the study of the transition from the Oldowan to the Acheulean, due to both the uniqueness of its archaeological record, and the influence of early investigations at Olduvai on the development of Early Stone Age research. This paper reviews the impact of work at Olduvai in shaping a modern view of cultural evolution from the Oldowan to the Acheulean. It also evaluates the lithic assemblages excavated by Mary Leakey in Olduvai Middle and Upper Bed II, based on a first-hand review of the collections. We conclude that previous paradigms used to explain inter-assemblage variability are not superseded as much as generally assumed, and that a modern view of the origins of the Acheulean requires a reassessment of the cultural, biological, and paleoecological evidence at Olduvai and elsewhere in Africa.     

The Lower Paleolithic of the Arabian Peninsula: Occupations,Adaptations, and Dispersals

To understand major processes of human evolution during the Plio- Pleistocene, it is necessary to consider the available evidence from key regions of the Old World. The Arabian peninsula is often depicted as a key geographic route for hominin dispersals in Out of Africa models, although the available primary evidence is rarely cited. And yet, significant Lower Paleolithic assemblages have been identified in many parts of the peninsula, including in areas near the Strait of Bab al Mandab. The presence of Oldowan-like and Acheulean assemblages may reflect at least two major dispersals outside of Africa. Acheulean localities are particularly abundant on the Arabian peninsula, and variations in stone tool manufacturing techniques and tool-type frequencies may reflect temporal changes in assemblages. Although there is good potential to chronometrically date sites in the Arabian peninsula, absolute dating methods have not been adequately applied, most temporal reconstructions relying on typotechnological change. If the Arabian peninsula is to provide solid evidence for understanding hominin adaptation and dispersal patterns, future fieldwork in secure depositional contexts needs to be conducted to overcome current limits in dating and environmental reconstructions.     

Reassessment of the Lower Paleolithic (Acheulean) presence in the western Tien Shan

Kulbulak (Uzbekistan) is among the most important Paleolithic sites in Central Asia. Based on excavations from the 1960s to the 1980s, a stratigraphic sequence yielding 46 archeological horizons of the Lower, Middle and Upper Paleolithic has been described. The lowermost 22 layers were at that time defined as Acheulean, both in cultural and chronological aspects. Based on these previous works, Kulbulak has thus often been cited as one of the rarest occurrences of Lower Paleolithic and Acheulean in the region. However, this attribution was debatable. New excavations at Kulbulak in 2007–2010 provided new material and the first reliable dates that permitted us to tackle this issue. Moreover, a reappraisal of the lithic collections and documents from previous excavations was also conducted. These new data clearly indicate the absence of Acheulean or even Lower Paleolithic at Kulbulak. On the contrary, the lithic assemblages from this site only correspond to Middle and Upper Paleolithic periods. The lowermost layers are particularly interesting due to the presence of an early industry with blade and bladelet technology.     

Critical reassessment of putative Acheulean Porosphaera globularis beads

Excavations at Acheulean sites in northern Europe at the end of the 19th century have yielded fossil sponges belonging to the Late Cretaceous species Porosphaera globularis. The spherical morphology of these fossils, their small size, and the presence of a natural complete perforation in their center have led some archaeologists to interpret them as the oldest known beads. Others argue that the presence of these fossils at archaeological sites is due to natural processes. Re-examination of material collected during the 19th century has recently revived the bead interpretation. We tested the bead hypothesis by analyzing 13 samples of Porosphaera from nine sites in Britain and France. We conducted morphometric and microscopic analyses on specimens recovered from archaeological sites (n = 349), a natural geological sample, which was collected directly from Cretaceous strata (n = 352), and a sample from a Bronze Age burial (n = 43). Reappraisal of contextual data shows that the association of these finds with Acheulean artifacts is uncertain. Our results show that archaeological specimens are significantly different in size and perforation pattern from those of the natural geological sample. This may be due to size-sorting caused by sedimentary processes, size-selection by Palaeolithic people or by 19th century collectors. Modifications of the fossils' natural shape were detected on a few specimens in the form of localized abrasions and microchipping along the hole margins. A single specimen displays a facet close to the hole produced by grinding. The surfaces of these features exhibit a hue lighter than that observed on the remainder of the specimens indicating that they may be recent in origin and due to post-excavation and preservation treatment. However, this seems contradicted, for some specimens from Bedford, by the fact that according to Smith, W.G. [1884. On a Palaeolithic floor at North-East London. Journal of the Anthropological Institute of Great Britain and Ireland 13, 357–384] the specimens bearing microchipping and abrasions were found by him and “not touched or manipulated by the workmen”. We conclude that new excavations of these sites, involving systematic screening of sediments, are needed in order to attempt to solve the Porosphaera “mystery”.     

The use of OSL dating in unstructured sands: the archaeology and chronology of the Hutton Sands at Canteen Kopje (Northern Cape Province, South Africa)

Archaeological research at the site of Canteen Kopje, Northern Cape Province, South Africa, has focused on the rich Earlier Stone Age assemblages recovered from the Younger Vaal Gravels. This paper presents the results of excavation and optically stimulated luminescence (OSL) dating of the overlying Hutton Sands. We discuss the evidence for colonial period interaction between diamond miners and indigenous groups at the site, as well as the presence of an earlier phase of terminal Middle Stone Age/early Later Stone Age occupation. The OSL analyses demonstrate the potential distortion of OSL ages due to substantial bioturbation and its effect on the dating of archaeological sites situated in unconsolidated sands.     

Living on the Edge? Transformation of a Marginal Pleistocene Landscape Into a Settlement Area in the Northeastern Part of the Netherlands

ABSTRACT

This paper will examine settlement location during the Iron Age in the northeast part of the Netherlands, an area shaped by Pleistocene geology. In recent years, a number of Late Iron Age/Early Roman settlements situated on the low lying slopes of sand ridges and nearby stream ridges revealed traces of an earlier Iron Age occupation. Palynological data revealed that this part of the landscape was used by humans before it was transformed into an area of settlement. An analysis of excavation data from two key sites at Denekamp-De Borchert and Groningen-Helpermaar, as well as other known sites, lead to the conclusion that the transformation of ‘peripheral landscapes’ into permanent settlement locations was preceded by a phase of arable cultivation which left no trace of permanent habitation. It is also suggested that the impact of human behaviour on the natural landscape in the Early and Middle Iron Age was much bigger than previously anticipated. When excavating this type of settlement areas dating to the Late Iron Age, archaeologists must be aware that only of a small group of archaeological features exist. The proposed model for the choice of settlement location may be more widespread, because of similarities in landscape between the study area presented here and other landscapes in Northwest-Europe (e.g. parts of Germany and Denmark).     

Plant microfossil analysis reveals disturbed forest and a mixed-crop,dryland production system at Te Niu,Easter Island

Plant microfossil analysis was carried out on 12 soil samples from a variety of landscape features at three locations (100–250 m a.s.l.) along a 950 m transect at Te Niu, Easter Island. Pollen and phytolith assemblages were dominated by palms and ground ferns, and suggested disturbed forest. We identified pollen of bottle gourd (Lagenaria siceraria) and starch grains of the common yam (Dioscorea alata), sweet potato (Ipomoea batatas) and taro (Colocasia esculenta). The data suggest a mixed-crop, dryland production system at Te Niu dominated by yam and sweet potato, and supplemented by taro and bottle gourd. The data provide direct evidence of crop type and range, supporting the indirect evidence (topographic and landscape features, field and historical research, comparisons with elsewhere in the Pacific) that much of the rock covered landscape of Easter Island was used for intensive horticulture.     

Insects in an abandoned landscape: late Holocene palaeoentomological investigations at Sandhavn,Southern Greenland

Abstract

The late Holocene landscape and environment at Sandhavn in Greenland's Eastern Settlement are considered in the light of recent palaeoentomological investigations. Samples dating to post-Norse peat accumulation suggest that Norse activity had no lasting effect on the beetle fauna and environment at Sandhavn after its abandonment in the Medieval period. The faunas recovered may be assumed to be characteristic of the surrounding environment, and indicate that the site was situated in an area of wetland and heath. The assemblages are discussed in the context of the sub-fossil and modern coleopteran faunal history of the North Atlantic islands, and as evidence for post-abandonment environmental conditions in Greenland.     

Did Modern Human Dispersal Take a Coastal Route into India? New Evidence from Palaeolithic Surveys of Kachchh,Gujarat

The Indian Ocean coastline is argued to have been a critical route of modern human dispersal from Africa, introducing Late Palaeolithic industries into South Asia, but a dearth of evidence has prevented a direct evaluation of this. Kachchh (Gujarat, India), located immediately east of the Indus Delta, is an important setting to appraise the Palaeolithic occupation of the western Indian coastline. Targeted survey of Late Pleistocene sediments there found widespread evidence for occupation of Kachchh during the Late Pleistocene: Middle Palaeolithic and possibly Late Acheulean lithic artifacts. The conspicuous absence of Late Palaeolithic industries in these Late Pleistocene deposits, with their presence only noted in Holocene contexts, does not support the model of modern human expansions into India with these industries via the coastal route. We evaluate these results in the context of current debates regarding Late Pleistocene hominin demography, adaptation, and expansions.     

Neolithic and Bronze Age ungulate footprint-tracks of the Severn Estuary: Species,age, identification and the interpretation of husbandry practices

Ungulate footprint-tracks provide information regarding the species and age of animals. Combined with other datasets, this contributes to interpretation of seasonal husbandry patterns in the Severn Estuary, focusing on Bronze Age intertidal footprint-tracks at Redwick and Goldcliff East and the Late Neolithic site of Oldbury. Metric dimensions and morphology of modern contemporary ungulate footprint-tracks are used as analogues to help understand the species and age of prehistoric ungulates. Findings indicate that Dexter cattle and Soay sheep are metrically similar to British prehistoric ungulates. The prehistoric sites have a concentration of neonatal and juvenile individuals. Along with evidence provided by environmental data, faunal skeletal assemblages and lipid and isotopic analysis, this leads to the conclusion that the presence of younger animals and evidence at Brean Down for dairying is consistent with saltmarsh grazing activity in spring and summer.     

Hunting strategies in the Late Glacial of northern Europe: A survey of the faunal evidence

Presented here is a general overview of the evidence concerning the procurement strategies in the Late Glacial of northwestern Europe. Their rich faunal assemblages make Stellmoor and Meiendorf, in northern Germany, key sites in this respect. Both may be considered specialized reindeer hunting camps. A survey of the hunting techniques and exploitation patterns reflected by the material from these sites emphasizes the differences between the Hamburgian and the Ahrensburgian economies.     

Archaeology of middle Pleistocene lacustrine and spring paleoenvironments in the Kapthurin Formation,Kenya

A number of key events occur in Africa during the middle Pleistocene including the disappearance of the Acheulian, the appearance of the Middle Stone Age, and the emergence of modern Homo sapiens. However, little is known about either the fossil or behavioral record for this critical time period. Excavation was undertaken at two middle Pleistocene archaeological sites, GnJh 42 and GnJh 50. These sites are located in close proximity to a large fresh water spring, a focal point on the landscape that supported a diverse plant and animal community. The lithic assemblages are dominated by flakes and cores, and lack all formal tools. However, the oldest evidence for systematic blade production can be found at these sites, indicating that important technological innovations were appearing at this time. Tendency to focus on the presence or absence of formal tools, means that assemblages of this age, lacking diagnostic artifacts, are typically subsumed within the Acheulian technocomplex. This practice disguises actual patterns of innovation and technological evolution. It is critical not to overlook this, as small-scale technological innovation allowed for more behavioral flexibility in response to rapid environmental change in a arid, mosaic environment.     

Neolithic and Bronze Age Agriculture in Southern Scandinavia – Recent Archaeobotanical Evidence from Denmark

Abstract

This paper presents archaeobotanical studies from the Danish regions of Thy, northern Schleswig and Djursland. The data are discussed in the light of developments in the landscape and in house architecture; comparisons are made with the contemporary situation in southern Sweden. Pollen analysis reveals that Thy was more or less treeless by the end of the Neolithic, whereas Djursland maintained its forests for a further 1500 years; the situation in northern Schleswig lies somewhere in between. Developments in house architecture are very similar in the three areas. The shift from two-aisled to three-aisled houses occurred in period I/II of the Bronze Age and phosphate analyses suggest that the earliest Danish byre dates from the beginning of period II.

Crop plant assemblages are dominated by naked barley and emmer and remain remarkably stable from the Single Grave Culture to the Late Bronze Age in Thy, from the Middle Neolithic to the middle of the Bronze Age in northern Schleswig, and from the Late Neolithic to the Late Bronze Age on Djursland. Other crops come and go – einkorn, bread wheat, spelt, millet, flax, oats and gold of pleasure. Hulled barley is largely conspicuous by its absence. Well-developed arable weed floras appear first in the Early Bronze Age – arable weeds are very scarce at Neolithic sites. There is evidence of improvement of arable soils using fen peat and household refuse and manure. The situation appears somewhat more complex in Denmark than that described for Sweden. The most striking difference is seen in the behaviour of hulled barley, which becomes massively dominant in Sweden in the course of the Bronze Age, whereas its role in Denmark is much more modest.
