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 Natufian economy at el-Wad Terrace with special reference to gazelle exploitation patterns

We carried out a detailed taphonomic and zooarchaeological analysis of the faunal remains from the new excavation of the Late Natufian layers of el-Wad Terrace. We focused on gazelle exploitation patterns and examined them within the context of the established Epipalaeolithic sequence from the coastal plain of Israel. Mountain gazelle (Gazella gazella) is the most heavily exploited species. The taphonomic history of the assemblage suggests minor loss of bones caused by post-depositional processes and indicates that bone destruction occurred during occupation. Cut marks from all stages of activities, absence of selective transport, and body part representation suggest that gazelle were butchered at the site. Analysis of gazelle sex composition shows male overrepresentation during the Natufian. Size trends show an increase of gazelle body-size during the Natufian in comparison to previous periods. The patterns of body-size increase show the same tendency in proximal and distal limb-bones. The trends in gazelle body-size from the Epipalaeolithic of the coastal plain do not demonstrate any sign of morphological dwarfism, increased variation, or allometric changes in the morphology of Natufian gazelles and thus do not support the previously suggested hypothesis of “proto-domestication”.     

Gazelle exploitation in the early Neolithic site of Motza,Israel: the last of the gazelle hunters in the southern Levant

We studied the faunal remains from the Early and Middle PPNB site of Motza, Judean Mts., Israel, in order to gain insight into the economic basis prior to livestock husbandry, with a focus on gazelle hunting. Taphonomic analysis showed that bone preservation at the site was excellent. The subsistence economy in Motza was based on a broad spectrum of hunted species, with mountain gazelle (Gazella gazella) as the dominant prey, similar to many Epipalaeolithic and Pre-Pottery Neolithic sites in the southern Levant. We studied gazelle exploitation patterns, in order to learn about the interaction of humans with this species prior to ungulate domestication. Analysis of the demography of the gazelle herd, which included aging and sexing, revealed no age preferences and no selective culling. Moreover, the PPNB gazelle population of Motza does not exhibit allometric changes in morphology, that are allegedly correlated to increased hunting pressure on gazelle populations prior to livestock domestication.     

“After 20 Years”: A Taphonomic Re-evaluation of Nahal Hadera V,an Epipalaeolithic Site on the Israeli Coastal Plain

We carried out a detailed taphonomic study of the faunal remains from Nahal Hadera V (NHV), a large Kebaran open-air site on the northern coastal plain, Israel. Faunal remains were previously identified to bone element and species (Saxon, Martin & Bar-Yosef, 1978). However, NISP and MNI values were calculated based on teeth and epiphyses only. In this study we identified the maximum number of skeletal elements, including head fragments, vertebrae, ribs, carpals/tarsals, and shaft fragments. Further analyses included search for various bone surface modifications and the study of mode of bone fragmentation. We found minor loss of bones caused by various diagenetic processes, and no signs of carnivore activity. These results suggest that most of the bone destruction was caused during time of occupation, probably for marrow consumption, as indicated by mode of bone fragmentation. Absence of selective transport for gazelle (Gazella gazella) and fallow deer (Dama mesopotamica), the major prey species (with 70% and 20%, respectively), is supported by homogeneous representation of head-limb-toe elements. However, the carcasses may have been processed before transport to the site. Thus, a taphonomic analysis from NHV helps to illuminate the economy of NHV inhabitants and fine-tunes our understanding of the depositional history of the site. However, it does not overthrow results of earlier research using classical methods.     

An exploration of character traits and linear measurements for sexing mountain gazelle (Gazella gazella) skeletons

The skeletal elements of mountain gazelle (Gazella gazella) have proven difficult to sex with statistical confidence due to wide overlap in the body size of the two sexes. We studied a sample of 53 modern mountain gazelle skeletons to determine which character traits and metric measurements best predict sex. The success of the character traits was determined using blind tests while the metrics were examined using discriminant function analysis. The most useful elements include the previously identified horn core, pubis and atlas, but also some new bone portions that preserve well in the archaeological record (e.g., distal tibia, distal metacarpal and metatarsal, and second phalanx). Surprisingly, two elements commonly used in sexing analyses (distal humerus and astragalus) were not among the most effective elements. Although cutting points and discriminant functions for sexing gazelle bone portions are presented here, they do not account for potential body size change and thus are not suited for direct application to archaeological assemblages. Instead, we provide guidelines for application to archaeological gazelle assemblages, most importantly a regression analysis that considers the sex ratios obtained from multiple measurements to predict the sex ratio of archaeological gazelle populations.     

Aging mountain gazelle (Gazella gazella): refining methods of tooth eruption and wear and bone fusion

This paper refines current methods for aging mountain gazelle (Gazella gazella), one of the most common species hunted by prehistoric humans in the southern Levant. Most importantly, we present a new tooth wear scheme for aging the lower deciduous fourth premolar (dP₄), the lower permanent molars (M₁, M₂, M₃) and the lower fourth premolar (P₄) of the gazelle. Broader wear stages for complete mandibles and individual teeth and bone fusion stages are also provided. Finally, a comparison of the tooth wear and bone fusion data indicates that the two methods can be linked at the important transition when a gazelle reaches adulthood (ca. 18 months of age). The completion of the fusion of the gazelle skeleton corresponds directly to the replacement of the dP₄ by the P₄ and the beginning of wear of the M₃. The coincidence of these aging indicators allows for direct comparison of gazelle bone fusion and tooth wear data.     

Identifying the Involvement of Multiple Carnivore Taxa with Archaeological Bone Assemblages

Information on the number of carnivore taxa that were involved with archaeological bone assemblages is pertinent to questions of site formation, hominid and carnivore competition for carcasses and the sequence of hominid and carnivore activity at sites. A majority of early archaeological bone assemblages bear evidence that both hominids and carnivores removed flesh and/or marrow from the bones. Whether flesh specialists (felids) or bone-crunchers (hyaenas), or both, fed upon the carcasses is crucial for deciphering the timing of hominid involvement with the assemblages. Here we present an initial attempt to differentiate the tooth mark signature inflicted on bones by a single carnivore species versus multiple carnivore taxa. Quantitative data on carnivore tooth pits, those resembling a tooth crown or a cusp, are presented for two characteristics: the area of the marks in millimetres, and the shape as determined by the ratio of the major axis to the minor axis of the mark. Tooth pits from bones modified by extant East African carnivores and latex impressions of tooth pits from extinct carnivore species are compared to those in the FLK Zinjanthropus bone assemblage. Data on tooth mark shape indicate greater variability in theZinj sample than is exhibited by any individual extant or extinct carnivore species in the comparative sample. Data on tooth mark area demonstrate that bone density is related to the size of marks. Taken together, these data support the inference that felids defleshed bones in the Zinj assemblage and that hyaenas had final access to any grease or tissues that remained.     

The Seasonal Mobility of Prehistoric Gazelle Herds in the Azraq Basin,Jordan: Modelling Alternative Strategies Using Stable Isotopes

The hunting of Gazella subgutturosa was a dominant practice for Epipalaeolithic and early Neolithic hunter–gatherers in the east Jordan steppe. The seasonal mobility of this taxon in the Levant is poorly understood, especially for early prehistory when herd movements would have influenced hunter-gatherer use of the steppes. This paper proposes four patterns of seasonal herd mobility for G. subgutturosa centred on Jordan’s Azraq Basin. The four patterns are modelled using oxygen, carbon and strontium stable isotopes. Seasonal environmental signatures of each are understood through carbon and strontium isotopic variation in sixty modern plant specimens collected from twelve selected locations in north Jordan, published data on oxygen isotopes in local precipitation, and the adaptive behaviour of G. subgutturosa. The integrated isotopic datasets provide clear discriminatory markers for each proposed mobility pattern. Results will be applied in future to isotopic data from archaeological gazelle teeth from the Azraq Basin.     

“Measure for measure”: a taphonomic reconsideration of the Kebaran site of Ein Gev I,Israel

We present the results of a detailed taphonomic study of the faunal remains from Ein Gev I, a Kebaran open-air site near the Sea of Galilee, Israel. In an earlier study faunal remains were assigned to bone element and species using a rapid method technique based on the identification of teeth and epiphyses only (Davis, 1974). In this study we identified the maximum number of skeletal elements, including fragments of long bone shafts. We also employed a series of taphonomic analyses to reconstruct the depositional history of the bone assemblage and to investigate subsistence, meat procurement and bone processing strategies. We compared the results obtained by a complete bone sampling method with those derived using a rapid method. The bone assemblage is dominated by mountain gazelle (Gazella gazelle), Mesopotamian fallow deer (Dama mesopotamica) and bezoar goat (Capra aegagrus). The assemblage is characterized by significant density-mediated biases, caused by both human bone processing behaviours and in situ post-burial bone attrition. Our attempts to compare species abundance derived from the two different identification protocols revealed no significant difference between the two sampling methods, both in terms of species diversity (richness and evenness) and skeletal element abundance (SEA). These comparisons contrast previous studies that expected to find ubiquitous head-and-foot dominated SEA profiles in zooarchaeological studies that were based on the incomplete identification of faunal remains.     

Subsistence and mobility strategies in the Epipalaeolithic: a stable isotope analysis of human and faunal remains at 'Uyun al-Hammam,northern Jordan

This paper investigates evidence for subsistence and settlement activities in the Levantine Middle Epipalaeolithic through the application of stable isotope analysis to human and non-human remains from the site of 'Uyun al-Hammam, northern Jordan. In general, bone from the site suffers a high degree of diagenesis and collagen could not be extracted for analysis here. Carbon and oxygen isotopic values from human tooth enamel samples were variable, but within expected values for the Middle Epipalaeolithic, whereas animal carbon and oxygen isotopic values varied widely, most likely due to hydrological and climatological factors. Carbon and isotopic values for the human samples indicated a predominantly C₃ plant dietary input, while animal samples appeared to have varying amounts of C₄ inputs into their diet. This is the first isotopic analysis conducted on material from the Middle Epipalaeolithic of the southern Levant and, as such, even results constrained by temporal and climatological variants within the region contribute to the overall knowledge of settlement and subsistence strategies during this cultural period.     

Macroscopic and microbiological alterations of bird and small mammal bones buried in a Cerrado biome (south western Brazil)

In this paper, we present the results of an experimental approach developed to study the macroscopic and microbiological alteration of bird and small mammal bones buried under a Cerrado biome. The first experiment evaluated the macroscopic alteration of cooked and fresh carcasses buried through the dry and rainy seasons. The second experiment analyzed the mycobiota associated to the decomposition of a complete bird that remained buried for almost a year. Results show that in tropical forest environments: 1) bone structure and pre-taphonomic factors determine its differential alteration by biochemical processes; 2) fungal populations associated to the decomposition of animal remains depend on soil chemistry and ecological dynamics; 3) even in a corrosive environment, bird bones are more capable of surviving to several mycological decomposition steps.     

FOCUS: on the use of the petrous bone for estimating cranial abundance in fossil assemblages

Low representation of braincase bones in zooarchaeological assemblages suggests that skulls have been intensively processed by Levantine Epipalaeolithic foragers; most cranial elements are often unidentifiable and are considered poor candidates for quantifying crania. In contrast, the petrous bone is usually found complete, and was found to be easily identifiable to body size category. Use of the petrous bone in fossil assemblages analyses leads to better estimation of the occurrence of cranial elements, and thus of skeletal part representation. We therefore suggest use of the petrous bone for detecting bone destruction and selective transport in faunal assemblages.     

Calcium isotopes in archaeological bones and their relationship to dairy consumption

The calcium isotope ratios (δ^44/42Ca) of bones from humans and fauna from three archaeological sites, Taforalt, Abu Hureyra, and Danebury, are evaluated in order to assess whether calcium isotope ratios of bones can be used to detect dairy consumption by adult humans. At each site the fauna δ^44/42Ca is the same regardless of species, while the humans have lower δ^44/42Ca than the local animals by 0.24–0.41‰ (site means). However we cannot ascribe this difference to dairy consumption, given this human–faunal difference also occurs in Epipalaeolithic and Mesolithic adult humans, where dairy consumption is unlikely. Rather, this difference appears to be a result of differences in metabolic processes or other aspects of diet between humans and fauna. Minimal isotopic change in sequential acid leaches of bone powders and consideration of the high calcium concentration in bone suggest that bone calcium isotope ratios are not substantially affected by diagenetic change.     

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.     

Carcass damage and digested bone from mountain lions (Felis concolor): implications for carcass persistence on landscapes as a function of prey age

This actualistic study examines the taphonomic signatures of modern free-ranging mountain lions (Felis concolor) on prey skeletal remains left at kill sites and digested bone fragments in the lions’ scats. Conducted in western Texas and southeastern New Mexico (U.S.A.), the study and its outcomes are relevant to models of carcass persistence and scavenging opportunities on ancient landscapes. Mountain lions in the study area ingested disproportionate quantities of bone from very young prey. This tendency holds true irrespective of prey body size. The results meanwhile confirm a relatively mild pattern of damage to adult deer carcasses. Digestive erosion of the surfaces of bones that passed through the gut was relatively severe, but many of these bone and tooth specimens retained identifiable features. It is clear that the mountain lions quickly remove the carcasses of very young prey from the pool of potentially scavenge-able resources. The non-linear relation between bone destruction from feeding by the cats and the skeletal maturity of prey also has consequences for prey mortality patterns, specifically a bias against the representation of very young individuals. This effect is not sufficient, however, to produce a global bias to prime-adult prey because older juveniles are much less affected.     

Comparing Levels of Subsistence Stress amongst Norse Settlers in Iceland and Greenland using Levels of Bone Fat Exploitation as an Indicator

Abstract

The background to the Icelandic and Greenlandic sites under investigation is outlined and prior work on the Norse economies of the two islands is discussed. The importance of fat in the diet and the use of levels of bone marrow and grease exploitation as an indicator of subsistence stress are explained. The methodology for establishing levels of bone fat exploitation is outlined. This methodology involves the detailed study of fragmentation levels of different types of bone, study of bone fracture types and many other taphonomic indicators. The results of the study are described and discussed. On Greenland, the Norse inhabitants exploited almost all available fat from land mammal bones, leaving only the ribs. It is argued that this indicates a severe level of subsistence stress amongst the Greenlanders that is most likely related to a seasonal dearth in resources. On Iceland, whilst a certain amount of bone marrow is almost certainly exploited, the settlers appear to almost totally ignore the potential to exploit bone grease. This is likely to be indicative of a much more healthy subsistence economy than on Greenland. These results are discussed in relation to differing climate, availability of good soil, fishing practices and seasonal rounds.     

The Bearded Vulture (Gypaetus barbatus ) as an Accumulator of Archaeological Bones. Late Glacial Assemblages and Present-day Reference Data in Corsica (Western Mediterranean)

Assemblages of 751 bone remains of an endemic Corsican deer (Megaloceros cazioti) from Late Glacial layers at Luri- Grı̀tulu cave (Northern Corsica) show an uncommon taphonomic pattern, mainly characterized by high dominance of third phalanxes and high rate of digestion marks. The authors demonstrate that this pattern cannot result from accumulation by human beings or by large mammal carnivores. The bearded vulture, which is able to accumulate large mammal bones in its nest and the presence of which is attested in the faunal remains at Grı́tulu, is the principal putative accumulator. In order to test this hypothesis, bone contents from 11 nests of modern Corsican bearded vultures (871 bone remains, i.e., more than 105 individual carcasses) are analysed from a taphonomic point of view. They are mainly characterized by overwhelming quantities of third phalanxes from middle-size ruminants, abundance and location of digestion marks around proximal articulations, and few bone flakes. A comparison of the Grı́tulu cave assemblages with these new present-day reference data leads to the conclusion that they have actually been accumulated by Late Glacial bearded vultures. Small discrepancies can, however, be explained by differences in food availability between the Late Glacial and modern times.     

Technological Change and Economy in the Epipalaeolithic: Assessing the Shift from Early to Middle Epipalaeolithic at Kharaneh IV

Epipalaeolithic hunter-gatherer communities in the Southern Levant exhibit numerous complex trends that suggest that the transition to the Neolithic was patchy and protracted. This paper explores the changing nature of occupation at the Epipalaeolithic site Kharaneh IV, Jordan, through an in-depth analysis of the lithic and faunal assemblages. Focusing on the analysis of a single deep sounding (unit AS42), we address how Kharaneh IV occupations link to the local landscape and environmental changes. As an aggregation site, Kharaneh IV represents an interesting locale to explore the changing nature of aggregation and social cohesion prior to the origins of agriculture, as well as changes in technology and subsistence between the Early and Middle Epipalaeolithic. We explore the tempo and nature of transition from one archaeological culture to the next through changes in technology and how this reflects the people making and using tools, to understand how foragers adapted to a changing landscape.     

The Middle Pleistocene argali (Ovis ammon antiqua) assemblages at the Caune de l'Arago (Tautavel,Pyrénées‐Orientales,France): were prehistoric hunters or carnivores responsible for their accumulation?

The argali (Ovis ammon antiqua) assemblages from the Middle Pleistocene site of the Caune de l'Arago (Tautavel, southern France) were studied in terms of zooarchaeology and taphonomy. It is possible to discern palaeobiological information lost during fossilisation, as well as the palaeoethology of the bone collector, by the observation of taphonomic details preserved on the bone assemblages. The observations leave no doubt that both humans and carnivores were involved in the accumulation of argali carcasses in the cave. In some assemblages, the type of bones found in articulation and the gnawing marks observed are characteristic of carnivores. In other levels, the intense fracturing of the major limb bones in relation to their marrow content and mineral density, and butchering marks found on specimens in the earlier levels, are in favour of human accumulation, the modalities of which are discussed. The results suggest that the degree of carnivore activity seems to have been higher in levels M, N and O than in level F. Copyright © 2006 John Wiley & Sons, Ltd.     

Late Pleistocene Eemian hyena and steppe lion feeding strategies on their largest prey—Palaeoloxodon antiquus Falconer and Cautley 1845 at the straight-tusked elephant graveyard and Neanderthal site Neumark-Nord Lake 1, Central Germany

The scavenging activities of hyenas and lions at the Neumark-Nord Lake 1 (Central Germany) site on straight tusk elephant carcasses is commonly documented by slight bone damages and initial skeleton partitioning. Canine bite marks are found at several joints of elephant long bones, as well as on the vertebrae and skulls. Deep bite and scratch marks from 5 to 7 mm in width made by large carnivore canine teeth (Panthera leo spelaea, Crocuta crocuta spelaea) on the ventral vertebral columns and pelvises of two Palaeoloxodon antiquus straight-tusked elephant skeletons suggest that the intestines and inner organs were consumed by both large lion/hyena predators as is commonly observed when modern African lions and spotted hyenas feed on contemporary elephant carcasses. A scavenging strategy can be demonstrated using 24 partly preserved Palaeoloxodon skeletons, where Ice Age spotted hyenas appear to be the main scavenger (95 %) and sole skeleton decompositor such as bone destructor. While Crocuta may feed anywhere on an elephant carcass, they are known to specialize to eat the complete feet, whereas scavenging from the anus into the body cavity (intestine/internal organ feeding) is more typical of lions. Shallow water at Neumark-Nord Lake 1 prevented hyenas from completely scavenging elephants; thus, bone damage at this site was constrained to initial stages of destruction and final carcass partitioning by high water stands and floods.
