A New Approach to Identifying Bone Marrow and Grease Exploitation: Why the “Indeterminate” Fragments should not be Ignored

The economic importance of bone fat to past peoples is discussed and the ethnography of bone marrow and grease extraction is briefly outlined. Models for expected patterns of bone fracture and fragmentation, relating to the exploitation of bone marrow and grease, are described. Current methods for assessing bone fracture and fragmentation, in archaeological assemblages, are discussed and a new methodology is suggested. The importance of retaining and studying the “indeterminate” class of fragments is stressed. The new methodology employs a fracture freshness index (FFI) to study fracture type, and fragmentation is assessed through the separation of fragments into size classes and different bone types. An example application is given.     

Evaluating Intensity in the Processing of Guanaco (Lama Guanicoe) at the Lower Basin of the Colorado River (Argentina): Fragmentation Levels and Fracture Patterns Analysis

This article explores the levels of fragmentation and fracture patterns in archaeofaunal assemblages from the lower basin of the Colorado River (Argentina) following Outram's methodology. Remains of ungulates (guanaco) have suffered, in these assemblages, a high degree of fragmentation probably caused during the processing of the carcasses. The presence of helical debris and shaft fragments indicates that fragmentation would respond to processing tasks for the consumption of marrow and possibly bone grease. The results of the application of this methodology that were obtained from the analysis of three late Holocene sites (La Primavera, Loma Ruiz 1 and El Tigre) are presented. These results provide new evidence not only for patterns of marrow and bone grease consumption but also for dealing with the subsistence model proposed for the study area. In this sense, the intensification processes already proposed during the final late Holocene (1000–250 bp ) are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

Fuel Fodder and Faeces: An Ethnographic and Botanical Study of Dung Fuel Use in Central Anatolia

Abstract

The Norse inhabited Greenland between AD 1000 and AD 1500 and, toward the end of the occupation, according to archaeological evidence, they were predominately marine mammal hunters. Despite the fact that marine resources became important for subsistence, the Norse Greenlanders settled the area in o?der to farm. This is indicated by site locations, faunal material, archaeobotanical, and palynological evidence.

Phytolith analysis from a quern stone, likely made from stone of local origin, found at Gården Under Sandet, a Norse farmstead in Greenland, was examined to determine if there was any evidence indicating domestic cereal processing. The phytoliths found on the quern stone can be associated with grasses and sedges, but the absence of dendritic phytoliths likely indicates that the quern stone was not used to grind seed. This preliminary study demonstrates that information about Norse agriculture may be obtained by examining the phytolith remains from a quern stone.     

A bone grease processing station at the Mitchell Prehistoric Indian Village: Archaeological evidence for the exploitation of bone fats

Recent excavations at the Mitchell Prehistoric Indian Village, an Initial Middle Missouri site in Mitchell, South Dakota have revealed a large, clay-lined feature filled with fractured and fragmented bison bones. Fracture and fragmentation analysis, along with taphonomic evidence, suggests that the bones preserved within the feature represent evidence of prehistoric bone marrow and bone grease exploitation. Further, the character of the feature suggests that it served as a bone grease processing station. Bone fat exploitation is an activity that is frequently cited as a causal explanation for the nature of many fractured and fragmented bone assemblages in prehistory, and zooarchaeological assemblages have frequently been studied as evidence of bone fat exploitation. The Mitchell example provides some of the first direct, in-situ archaeological evidence of a bone grease processing feature, and this interpretation is sustained by substantial analytical evidence suggesting bone fat exploitation. This new evidence provides a clearer concept of the nature of bone fat exploitation in prehistory as well as an indication of the scale and degree to which bone grease exploitation occurred at the Mitchell site. Finally, this research demonstrates the importance of careful zooarchaeological and taphonomic analysis for the interpretation of both artifactual remains as well as archaeological features.     

Bone mineral content in medieval Greenland Norse

The bone mineral content (BMC) was measured using a special dual-photon scanner in 25 mandibles with normal macroscopic and radiographic bone structure. The mandibles were excavated from two Norse sites in Greenland, which date to the first and last part of the medieval Norse settlement period, respectively. The main purpose of this study was to investigate whether there was a change in BMC levels between the early and the late settlement period. The results showed no difference in male BMC between the early and the late site material. A statistically significant gender difference was found, analogous to most clinical and archaeological BMC studies. The sample did not allow testing for age-related, especially female postmenopausal-related, bone loss. It is known that Eskimos generally have a very low BMC, probably the effect of a high-protein marine diet. The lack of decrease in BMC levels for the Norse could indicate that they did not increase their overall protein intake over the 500-year settlement period. Other studies (both archaeological and anthropological) point to an increased reliance on marine foodstuffs throughout the settlement period. Thus, if the Norse increased their reliance on marine foodstuffs, they probably did not do so to the extent of an almost exclusive marine diet like that of the Eskimo. © 1997 John Wiley & Sons, Ltd.     

Dietary Stress and Animal Resource Use at the Postclassic Maya city,Mayapán (Mexico)

ABSTRACT

Environmental changes resulting in drought and reductions in the availability of animal resources during the Late Classic Maya have been linked with the Maya ‘collapse’. Decreases in availability of dietary staples such as artiodactyls, and particularly white-tailed deer, during the Late Classic period would have placed food stress on populations during later periods. To test this hypothesis, here bone breakage patterns are examined at the Postclassic Maya city, Mayapán, to assess whether artiodactyl bones were being intensively processed for bone fats (marrow and grease). Fragmentation morphology, size and surface markings, along with skeletal part representation and distribution of large mammal bones were recorded for bone assemblages from several houselots. Evidence suggests the Maya were likely utilising bone marrow from artiodactyls but not intensively and they were not extracting bone grease. These results indicate that decreased accessibility to artiodactyls during the Postclassic was not causing high levels of dietary stress for the Maya at Mayapán, which is consistent with recent evidence demonstrating dietary consistency during the Postclassic in northern Yucatan.     

Pastures lost? A dental microwear study of ovicaprine diet and management in Norse Greenland

The management of ovicaprines by the Medieval Norse farmers in Greenland is explored using dental microwear analysis. Adult and juvenile ovicaprines from Norse contexts in Greenland are shown to exhibit microwear patterns very different to those in modern Greenlandic sheep; while modern sheep demonstrate microwear consistent with low levels of soil ingestion under extensive, low stocking-rate grazing regimes, Norse sheep/goat display striated microwear patterns indicative of high levels of soil ingestion and, potentially, overgrazing. This high abrasive grazing signature is present in the inland region of the Western Settlement from 1150 AD onwards, may be evident in the inland Eastern Settlement from an equally early date and is also detected during the later phases of occupation in the Western settlement (14th and 15th centuries AD). It is argued that these results provide further evidence that maladaptive grazing practices led to a decline in the viability of pastoral farming in Greenland, and, moreover, that overgrazing did not merely occur towards the end of the settlement as a consequence of the worsening climate of the ‘Little Ice Age’ but rather was present in both the Western and the Eastern Settlement from a relatively early date.     

Russia and Norway: Research Collaboration and Comparison of Asymmetrical Relations

Archaeological excavations in 1954, 1958, and 1962 directed by Dr. C.L. Vebaek of The Danish National Museum at the Norse site 0 17a in the modern Greenlandic town of Narssaq revealed a farmstead apparently occupied from the 11th century into the later phases of the Eastern Settlement. The excavations recovered a quantifiable amount of animal bone from well‐defined strata within and immediately around the main structure. These collections were analysed in 1976–77 by the authors and show both continuity and some important changes in subsistence patterns between occupational strata.     

The Norse settlers in Greenland: The physical anthropological perspective

Abstract

Recent studies of the Norse settlements on the west coast of. Greenland, which point to theories of biological adaptation, have emphasized the need for a comprehensive physical anthropological investigation of the Norse skeletal material, especially along the lines of paleodemography. The material, comprising the remains of app. 350 individuals, is presently stored at the University of Copenhagen. As the first step in a major investigation, the material has been incorporated into a computer database, linking anthropological and archaeological data. The aims of such a major physical anthropological investigation are presented here.     

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.     

Geographical Variation of Subsistence Strategies in Early Mediaeval Populations of Southwestern Germany

The investigation is based on bone element data of early Mediaeval human skeletal samples from eight differing environmental conditions in lowland and mountain range localities of southern Germany. Reconstruction of plausible subsistence strategies revealed close correlations with the respective ecological potentials of the localities as indicated by proxy data on geomorphology, climate, and soil quality. In general, lowland situations showed mixed dietary patterns with a prevalence of agricultural farming, whereas in mountainous areas the emphasis was on dairy farming production and horticulture. This points to subsistence activities during the early Middle Ages that are closely adjusted to differing environmental conditions. An obvious deviation from this pattern in one locality (Kirchheim unter Teck) is explained in terms of successful socio-cultural buffering of limited but effective exploitation of the natural setting.     

Gazelle bone marrow yields and Epipalaeolithic carcass exploitation strategies in the southern Levant

We measure the bone marrow yields of mountain gazelle (Gazella gazella) carcasses to reconstruct gazelle exploitation strategies during the Epipalaeolithic periods in the southern Levant. We present experimentally derived data on the bone marrow content of seven fresh gazelle carcasses, determine the range of marrow yields among individuals of different sexes and seasons of death, and compare the new data to gazelle skeletal element abundances from five Epipalaeolithic assemblages from Israel. We found extensive variation in marrow fat content among individual gazelles. Animals with the highest marrow yields were killed in the spring while animals killed in the early autumn had lower fat contents. Nevertheless, our results suggest that gazelle marrow provided a reliable, albeit small fat resource for prehistoric foragers in all seasons. Strong relationships between bone fragmentation and marrow content demonstrate that Epipalaeolithic people preferentially processed bones with high marrow yields.     

A charcoal-rich horizon at Ø69, Greenland: evidence for vegetation burning during the Norse landnám?

It is often assumed that the colonisation of Greenland by Norse settlers in c. A.D. 985 had a sudden and dramatic effect on the environment, involving substantial vegetation clearance and environmental degradation. Consequently, it has been argued that charcoal-rich horizons, visible in many sections in Greenland, represent the initial burning of the vegetation by Norse farmers to create land suitable for agriculture. In this study a charcoal-rich layer, visible in a modern drainage ditch beside the Norse farm of Ø69, was analysed using archaeobotany, sedimentary analysis and radiocarbon dating to test the date and formation processes of the horizon. It is demonstrated that the charcoal-rich layer at Ø69 was not derived from in situ vegetation burning in the 10th century and concluded that the layer was probably formed by the addition of midden material to the infields around Ø69 in the 13th and 14th centuries cal AD, perhaps as part of a soil amendment strategy. It is argued that caution must be exercised when interpreting charcoal-rich horizons as time-specific chronological markers in palaeoenvironmental sequences in Greenland.     

Soils and palaeo-climate based evidence for irrigation requirements in Norse Greenland

Establishing and sustaining agricultural production was a key factor in the success of Norse settlements during the landnám colonisation across the North Atlantic. In light of the occurrence of channel features in several abandoned home-field areas of the Norse Eastern Settlement of Greenland, and the irrigation requirements of present-day Greenlandic sheep-farmers questions are raised: was irrigation used by the Norse settlers of Greenland on their home-field areas? and, if so, how frequently? Modelling of soil chemical, physical and soil-water hydraulic properties integrated with contemporary high-resolution climatic data demonstrate a frequent requirement for irrigation. Soil moisture deficits are related to the duration and intensity of winter temperature. Using the winter Dye 3 ice core δ¹⁸O record as a climatic proxy, the frequency of moisture deficits, based on comparing mean winter temperatures, indicates that there was a frequent irrigation requirement to maintain home-field productivity, increasing throughout the period of settlement until the 14th Century.     

Skates and Prickers from the Circular Fortress of Oost-Souburg,The Netherlands (AD 900–975)

Abstract

During the excavation of the circular fortress of Oost-Souburg, the Netherlands, objects of bone and antler were found: combs, needles, spindles, three-pronged objects, bone skates and points. The finds are dated between AD 900 and 975. In this contribution the objects which belong to the winter season, the bone skates and the points, are discussed. The skates occur in various types and are made of a variety of bones. Certain types of skate were used without bindings, others were either designed to be fastened to the feet or possibly were tied only at the heels. The roughly-made points that were found may be the points of the prickers used to propel the skater forward on his skates.     

Declining foraging efficiency and moa carcass exploitation in southern New Zealand

The application of foraging theory to understanding carcass exploitation is a relatively recent development. The methodology developed by archaeological and ethnoarchaeological research on butchery/transport studies has been integrated into a behavioral ecological framework to create models that can be used to understand archaeological carcass exploitation. In this paper, I use such a model to examine how New Zealand foragers altered their use of moa carcasses as the availability of these large birds declined. Moa data from the Shag River Mouth site in southern New Zealand are analyzed to test changes in butchery/transport and skeletal element breakage patterns expected with resource depression and declining foraging efficiency. This research shows that at Shag Mouth, field processing of moas increased and marrow, and possibly grease extraction intensified over time.     

Seasonal Aspects of Bronze and Iron Age Communities at Ra's al-Hadd,Oman

Abstract

Excavations of third millennium BC and later settlement, burial and workshop sites have been carried out at Ra's al-Hadd, Oman in 1988–9 and 1992 under the direction of Dr J. Reade. These excavations form part of the Joint Hadd Project, a multi-disciplinary programme of research co-directed by Dr S Cleuziou, Dr J Reade and Professor M Tosi; the Ra's al-Hadd portion of the Joint Hadd project is sponsored by the British Museum and the Ministry of National Heritage and Culture, Sultanate of Oman and the Ra's al-Junayz portion by I.S.M.E.O and the C.N.R.S.

Environmental evidence from the Ra's al-Hadd sites includes charcoal, charred fruits and seeds, mammal and fish bones, land and marine molluscs. Evaluation of pollen samples is in progress. This paper examines aspects of the ongoing environmental research which aims not only to re-create patterns of resource exploitation through time, but also to chart possible seasonal variability in cultural, subsistence, economic and trading terms. Some comparisons will be made with the dynamics of the present system of seasonal resource exploitation by the Ra's al-Hadd community.     

Gazelle bone fat processing in the Levantine Epipalaeolithic

We investigate mountain gazelle (Gazella gazella) carcass processing to reconstruct resource intensification strategies during the Epipalaeolithic period of northern Israel. We adopt a multivariate taphonomic approach to identify the processes that most influenced bone survivorship in five gazelle assemblages. All of the assemblages are characterized by significant density-mediated biases, yet in situ attrition played a minimal role in assemblage formation. In contrast, the survivorship of hare (Lepus capensis) skeletons is not mediated by bone density indicating that different prey taxa experienced independent taphonomic histories. Both gazelle cortical and cancellous bone is highly fragmented and the degree of fragmentation and survivorship are strongly correlated with fat yields. Results of multiple tests point to intensive marrow and grease extraction as the primary determinant of gazelle bone survivorship. Although gazelle carcasses were intensively utilized throughout the Epipalaeolithic, the intensity of use is stable across the duration of the period.     

The Exploitation of Carnivores and Other Fur-bearing Mammals during the North-western European Late and Upper Paleolithic and Mesolithic

The exploitation of large mammals, particularly large herbivores, has dominated perceptions of Upper Palaeolithic and Mesolithic subsistence behaviour in north-western Europe. This paper critically reviews the evidence for the exploitation of a complementary resource which has received little attention within the archaeological literature — carnivores and other fur-bearing mammals. Evidence for exploitation of individual species is described and discussed. A model is then developed to explain the apparent expansion of the subsistence base to include a wide range of fur-bearing mammals during the Lateglacial and Mesolithic. This paper concludes by arguing that although the use of carnivore meat and pelts cannot be viewed as a dominant trend in European hunter-gatherer subsistence practices, their contribution to hunter-gatherer economies cannot be ignored.     

Túnel: A Case Study of Avian Zooarchaeology and Taphonomy

Although not often considered, there are many osteological characters unique to the avian skeleton that influence the taphonomy of bird bones. These characters are reviewed and their archaeological significance discussed herein. The presence of marrow in many avian long bones is important to interpretation of avian remains from archaeological sites because the presence of marrow affects bone density and, in turn, preservation. Other structural properties that affect avian bone preservation include cortical wall thickness, length and pneumatic state. Based on an analysis of approximately 10,000 bird bones from the archaeological site of Túnel, Tierra del Fuego, Argentina, I found that specific breakage patterns resulted from natural taphonomic processes acting as a result of the unique avian bone characteristics. This information may allow researchers to distinguish breakage patterns in avian bones resulting from natural taphonomic processes from breakage patterns that are culturally induced.
