Why are cut mark frequencies in archaeofaunal assemblages so variable? A multivariate analysis

Cut mark frequencies in archaeological faunal assemblages are so variable that their use has recently created some skepticism. The present study analyses this variability using multivariate statistics on a set of 14 variables that involve differential skeletal element representation, fragmentation processes, carnivore ravaging impact, carcass size and tool type. All these variables affect the resulting cut mark frequencies reported in archaeological sites. A large sample of archaeofaunal assemblages has been used for this study. It was concluded that the best estimator of cut mark frequency in any given assemblage is the percentage of cut-marked long bone specimens (probably due to its better preservation than other anatomical areas), which is determined by fragmentation and carnivore ravaging. Carcass size and tool type also play a major role in differences in cut mark frequencies. Fragmentation is also a key variable determining the abundance of cut-marked specimens. It is argued that general cut mark percentages are of limited value, given the number of variables that determine them, and that a more heuristic approach involves quantifying cut marks in a qualitative manner.     

Les Pradelles (Marillac-le-Franc, France): A mousterian reindeer hunting camp?

The site of Les Pradelles has an important mousterian stratigraphic sequence. In the lower levels, the very low density of artefacts as well as the carnivores scavenging of carcasses abandoned by the neanderthals point to short-term human occupations; the introduction of finished tools (made on non-local, good quality flint) later highly curated, together with an expedient strategy on strictly local flint, suggest a task-specific location, within a low mobility pattern. The large faunal sample (mainly reindeer) underlines the preponderance of hunting activities. A range of butchering activities took place on the site and the abundance of filleting marks may be an indication of the processing of meat for transport to another settlement. The hypothesis of “specialized hunting” during Middle Palaeolithic is assessed with this new data set.     

Quantitative micromorphological analyses of cut marks produced by ancient and modern handaxes

In this study, we analyse the three-dimensional micromorphology of cut marks on fossil mammal remains from a ∼0.5 million year old Acheulean butchery site at Boxgrove (West Sussex, southern England), and make comparisons with cut marks inflicted during the experimental butchery of a roe deer (Capreolus caproelus) using a replica handaxe. Morphological attributes of the cut marks were measured using an Alicona imaging microscope, a novel optical technique that generates three-dimensional virtual reconstructions of surface features. The study shows that high-resolution measurements of cut marks can shed light on aspects of butchery techniques, tool use and the behavioural repertoire of Lower Palaeolithic hominins. Differences between the experimental cut marks and those on the Boxgrove large mammal bones suggest variation in the angle of the cuts and greater forces used in the butchery of the larger (rhinoceros-sized) carcasses at Boxgrove. Tool-edge characteristics may account for some of these differences, but the greater robusticity of the Boxgrove hominins (attributed to Homo heidelbergensis) may be a factor in the greater forces indicated by some of the cut marks on the Boxgrove specimens.     

Butchering and cooking of birds in the palaeolithic site of Grotta Romanelli (Italy)

Grotta Romanelli is one of the most important sites of the Italian palaeolithic. It contains a lithic industry from the Final Epigravettian, examples of rock and mobiliary art and numerous bone remains, among which were abundant remains of birds. Approximately 32 000 bird bones from over 3650 individuals and 109 species were identified. The most common species were bustards, Otis tetrax and O. tarda, and three species of goose, Anser fabalis, A. albifrons and Branta bernicla. Traces of butchering and burning were evident on numerous bones. The nature and location of the cut marks and burning is described here. The analysis has involved mostly the hind limbs and the shoulder girdle where traces are most numerous. The cut marks reflect a codified sequence of actions of disarticulation and dismemberment. © 1997 John Wiley & Sons, Ltd.     

Cut marks on the Middle Pleistocene elephant carcass of Áridos 2 (Madrid,Spain)

Áridos 1 and Áridos 2 (Madrid, Spain) are two Middle Pleistocene sites belonging to the isotopic stages 9–11. Both places contain partial carcasses of Elephas (Paleoxodon) antiquus associated to Acheulian stone tools. In this work, the taphonomic study of the elephant remains of Áridos 2 is presented. This study has documented several cut marks on different bones, which indicate bulk flesh and viscerae extraction by Middle Pleistocene hominins. Several arguments are provided to support that at least some of the cut marks were made with handaxes, further suggesting that some of these artifacts were butchering tools in this stage of human evolution. Although cut marks on elephant carcasses have been documented at some Middle Pleistocene sites, very few have been published in detail to allow consideration of their status as hominin-imparted marks. By doing so, the present study provides more evidence of large carcass exploitation by hominins during this period.     

Identifying sword marks on bone: criteria for distinguishing between cut marks made by different classes of bladed weapons

Swords have been one of the major weapons used in violent conflicts for much of human history. Certain archaeological situations, especially those dealing with the recovery and analysis of battle casualties, may raise questions about what type(s) of bladed weapon was used in a particular conflict (e.g., the battle of Kamakura, Japan, AD 1333; the battle of Wisby, Sweden, AD 1361; the battle of Towton, England, AD 1461). Little work has been done, however, on developing criteria to differentiate sword cut marks from other types of cut marks, or to distinguish between marks created by different sword types. To develop such criteria, bovine tibiae (n = 7) were struck using six different types of bladed weapon and the resulting marks (n = 92) were analyzed. Eight traits describing the morphology of the cut mark – such as shape, the presence and unilateral/bilateral state of flaking and feathering, the presence of bone shards, associated breaks, etc. – are defined and related to blade type used. Sword marks were found to be easily distinguishable from knife marks. The variation in marks made by different sword types is significantly correlated with differences in blade weight (p < 0.0001), grip (p < 0.0113), and sharpness (p ≤ 0.0179). The criteria and analyses developed and implemented in this study will be of use to researchers in forensics and osteoarchaeology who want to infer bladed weapon type from marks on bones.     

Elephants and subsistence. Evidence of the human exploitation of extremely large mammal bones from the Middle Palaeolithic site of PRERESA (Madrid, Spain)

The archaeological site at PRERESA (Madrid, Spain) has been dated to 84 ± 5.6 ka by optically stimulated luminescence (OSL) (MIS 5a). An area 255 m² was excavated and 754 lithic pieces were recovered, as well as a large amount of micro and macro vertebrate remains, including proboscidean bones. The aim of this paper is to outline the results of the taphonomic study of these remains. The identification of cut marks on a number of the bones recovered strengthens the theory that the exploitation of extremely large mammals was more than just a marginal practice before the Upper Palaeolithic. Additionally, the identification of green-bone fractures and percussion marks confirm for the first time, that the bone marrow of these taxa was also consumed. Few other cases of this practice have been identified, firstly because obtaining this substance would not be an easy matter, and secondly because similar nutritional needs can also be met by the consumption of brain matter, which is easier to acquire.     

The Ethnoarchaeology of Reptile Remains at a Lake Turkana Occupation Site, Kenya

The role of reptiles in hominid hunter–gatherer subsistence in Pleistocene Africa has been largely overlooked. This study examines the reptile component of a modern lake shore camp (site 20) assemblage of low archaeological visibility. Site 20, located on the eastern shore of Lake Turkana, has been observed from its creation to burial. The site is an ideal modern analogue for the interpretation of African prehistoric archaeological sites. Patterns of element loss, and patterns of bone modifications, namely burn, cut and slice marks, are examined. From this baseline data, three conclusions are drawn regarding the interpretability of reptile remains found at archaeological lakeside sites: (1) the MNI of crocodile remains at a site is likely to be similar to the original number of individuals which contributed to the deposited assemblage; (2) the MNI estimates of the turtle component will be much less than the original number of individuals in the deposited assemblage; and (3) patterns of bone modifications can be related to hominid food procurement and processing activities.     

Repeat silica extraction: a simple technique for the removal of PCR inhibitors from DNA extracts

Polymerase chain reaction (PCR) inhibitors are often co-extracted with ancient DNA (aDNA) and when present make the analysis of aDNA difficult, if not impossible. In this study we review previous research on PCR inhibitors and techniques that address their co-extraction with DNA from sub-optimal samples. Additionally, we introduce a simple extraction technique, “repeat silica extraction,” that effectively removed PCR inhibitors from extracts of 7000–8000-year-old human skeletal remains from the Windover archaeological site in Florida and 700–2000-year-old human coprolites excavated from Fish Slough Cave in southern California. A series of tests on these same samples demonstrates that N-phenacylthiazolium bromide is largely ineffective, despite previously reported success using this compound as part of the DNA extraction process. We also describe a method for demonstrating the presence as well as successful removal of PCR inhibitors by use of a “positive aDNA control,” a test necessary to conclude that negative PCR amplification is the result of the absence of preserved DNA.     

A system for classification and description of the horn cores of cattle from archaeological sites

A system is proposed for the classification and sexing of the horn cores of cattle recovered from archaeological sites. The cores are first divided into four groups depending on their length. The terms “small”, “short”, “medium” and “long horned” are given to these groups but bear no relation to the names used for modern breeds of cattle. After differentiation according to length, the sex of the core is designated by visual appraisal of the shape, curvature and angle of attachment of the cores to the frontal bones. It is not claimed that the sex of individual horn cores can always be established but from the sample of 80 cores that we tested by statistical analysis (presented in an appendix) it was evident that the categories based on length and assessment of sex did separate out as expected.     

Droughts as random events in the Maya lowlands

Because the values of most of the parameters controlling the occurrence and severity of a drought in a given location are unknown, and no periodicity has been observed, droughts can be considered random events. Running a random number generator within the limits of the annual rainfall variability relevant to the Maya lowlands, and defining a “Lean Year”, it is observed that strings of lean years occur quite frequently. Defining “Severe Drought”, “Disaster”, and “Catastrophe” based on the length of these strings, it is observed that a severe drought occurs on average every 32 years, a disaster occurs on average every 130 years, and a catastrophe on average every 500 years. These values fit the measured variability of the Yucatan climate, as observed in lake core sediments and in the post conquest written records. It also fits the average occurrence of “megadroughts” in the US Great Plains.The fit between the random occurrence model and the actual, “measured” occurrence of droughts supports the notion that for all practical purposes, droughts had been random events in the Maya region and could not be predicted. The lack of evident periodicity could be one of the reasons why means for long-term storage of food products were not developed there. It may also have affected the relationship between the priesthood and the general populace in that region.Since the method described here can be applied to any climatic region once the rainfall variability and the sensitivity of the local agriculture are known or can be estimated, if similar results are found they may probably have affected other regions with other ancient cultures in a similar way.     

Dating of modified femora of extinct dwarf Hippopotamus from Southern Madagascar: Implications for constraining human colonization and vertebrate extinction events

Two significant events in the late Holocene history of Madagascar were (a) the arrival of people, and (b) the loss of nearly two dozen species of land vertebrates in the socalled “subfossil extinctions”. The consensus is that the faunal losses occurred shortly subsequent to human arrival, but the timing of these events is poorly constrained. The minimum age for initial human presence on the island may now be set at approximately 2000 bp, on the basis of AMS ¹⁴C dates for human-modified femora of extinct dwarf hippos from SW Madagascar. Assuming that this date also marks the beginning of deleterious human interactions with the subfossil fauna, and assuming that this fauna became completely extinct by 900 bp, the width of the anthropogenic “extinction window” may have been as long as c. 1000 a. This estimate, nearly twice the length of previous ones, is close to the unadjusted minimum for the duration of the terminal Pleistocene extinction event in the Americas. Whether or not this length of time comports with theoretical expectations of a “blitzkrieg” pattern of losses is uncertain, but greater refinement in dating the end of the subfossil extinctions is unlikely to produce radically shorter estimates of duration.     

Top-down or bottom-up: rural settlement and raised field agriculture in the Lake Titicaca Basin, Bolivia

Differing interpretations regarding the organization of past intensive farming are often distinguished as “top-down” or “bottom-up” perspectives. The development of intensive farming and its social organization are attributed to either nascent states and centralized governments or the incremental work of local communities or kin-based groups. We address the social organization of raised field farming in one region of the Lake Titicaca Basin of the Andean altiplano, Bolivia. We evaluate past research in the Katari Valley, including our own, based on recent settlement survey, excavation, and a variety of analyses. Taking a long-term perspective covering 2500 years, we find that relations of production and rural organization changed greatly over time in relation to changing sociopolitical conditions. Local communities played dynamic roles in the development and organization of raised field farming, yet its intensification and ultimate recession were keyed to the consolidation and decline of the Tiwanaku state. We conclude that the top-down/bottom-up dichotomy is overdrawn. Local communities and their productive practices never operated in a political or economic vacuum but both shaped and were transfigured by regional processes of state formation, consolidation, and fragmentation.     

Late Mesolithic hunting of a small female aurochs in the valley of the River Tjonger (the Netherlands) in the light of Mesolithic aurochs hunting in NW Europe

The valley of the River Tjonger, situated in the Province of Friesland (the Netherlands), is rich in prehistoric organic remains. The fill of the valley, consisting of waterlogged sediments (peat, gyttja and sands), presents favourable conditions for the preservation of bone, antler and botanical remains. Numerous bones with chop and cut marks, in majority of aurochs (Bos primigenius), are known from several locations in the valley. The Late Mesolithic (ca. 8000–5500 BP) is especially well represented. In this paper we present a recently discovered small hunting and butchering wetland site dating to the Late Mesolithic. The site, named Balkweg, represents a single hunting and primary butchering event pertaining to a small female aurochs with a height at the withers of 134 cm. The morphology of the vertebrae and the phalanges as well as the Late Mesolithic date confirm the identification as an aurochs cow. Single event sites are underrepresented in the archaeological record due to their small size and poor visibility. The importance of aurochs hunting during the Mesolithic is discussed in this paper as well.     

Lapa das boleiras rockshelter: stratigraphy and formation processes at a paleoamerican site in Central Brazil

Lapa das Boleiras rockshelter, a Paleoamerican archaeological site in Central Brazil, was intensely occupied by humans from 10,000 ¹⁴C BP (11.8 cal kyr BP), until approximately 7500 ¹⁴C BP (8.4 cal kyr BP). In this paper we present some interpretations about the formation processes operating on the site. One of our main conclusions is that the bulk of accumulated sediments at the site is of anthropogenic origin: they are constituted by volumetrically significant quantities of plant ash remains, what is somewhat unexpectedly in view of prevailing models about the lifestyle of Paleoamerican hunter–gatherers in South America. The evidence we discuss below is also consistent with paleoenvironmental data that suggest a dry period during the mid-Holocene in the region, probably leading to a decrease in human occupation [Araujo, A.G.M., Neves, W., Piló, L.B., Atui, J.P., 2005. Holocene dryness and human occupation in Brazil during the ‘Archaic Gap’. Quaternary Research 64, 298–307]. We surmise that both factors underpin a surprising reduction in sediment accumulation at the site during the mid-Holocene.     

Ceramic production and provenience at Gordion, Central Anatolia

Phrygian Gordion was the political center of an influential Iron Age polity that extended across west central Anatolia during the first half of the 1st millennium BC. Though the borders of this polity remain vague a characteristic of the Phrygian “footprint” is the distribution of highly distinctive ceramics. The extent to which Gordion potters were the originators of these wares remains uncertain. In this paper we use Neutron Activation Analysis (NAA) to establish the local signature of predominantly Iron Age ceramics for this site by combining samples from several decades of excavation with an extensive regional sediment sequence. We also compare previous NAA work at Gordion to suggest that the formative stages of the Phrygian state appears to have involved a more extensive network of non-local specialist producers than previously thought.     

Patterns of social identity in relation to tooth ablation among prehistoric Jomon foragers from the Yoshigo site,Aichi prefecture,Japan

This study documents and interprets patterns of identity in relation to tooth ablation patterns at Yoshigo, a Late/Final Jomon period (3500–2500 yBP) site. Two patterns of tooth ablation are observed among the Yoshigo people: both (2) mandibular canines or four (4) mandibular incisors were extracted during life and formed a basis for identity differentiation. Three hypotheses are tested regarding these groups: (1) tooth ablation groups will be unrelated to postmarital residence; (2) tooth ablation groups will be associated with age‐based achievements; (3) tooth ablation groups will be associated with occupational specialisation. Biodistance, demographic and stable isotope analyses were performed on skeletal remains recovered from Yoshigo (3500–2300 BP) to test these hypotheses. Within‐group variation expressed by cranial and dental measurements was not significantly different between tooth ablation groups. This indicates that tooth ablation practices were not related to migration. Previous biodistance findings do, however, suggest that tooth ablation groups represent closely related individuals, possibly kin‐based networks. Demographic analysis of age‐at‐death and tooth ablation suggests that tooth ablation styles were achieved at different ages. Stable isotope analysis indicates that the tooth ablation groups consumed similar foods. Based on isotopic findings from other sites and archaeological evidence for food sharing among Jomon people, these results suggest that dietary variability between tooth ablation groups was homogenised by cooperative food sharing. The totality of these findings support the hypothesis that the identities associated with tooth ablation were unrelated to migratory patterns, and instead, possibly reflect kin‐based social units, where achievement or age acted as a determinant of membership.

Survival of a multiple skull trauma: the case of an early neolithic individual from the LBK enclosure at Herxheim (Southwest Germany)

The Early Neolithic enclosure of Herxheim yielded the human remains of more than 450 individuals mainly represented by cranial vaults and numerous fractured cranial and postcranial bones. The skulls were shaped post‐mortem into skull caps by intentional separation of the cranial base and facial bones. One of these calottes revealed four ante‐mortem traumatic lesions and additional cut marks.The defects of this individual were analysed in detail to obtain information on the chronology and consequences of the traumata and manipulations and their probable intention. Four marks could be attributed to at least two violent incidents because of their different stages in the healing process. There is no evidence of cranial surgery, but the individual may have received some medical treatment and social care to survive the injuries without complications. The peri‐mortem cut marks and the post‐mortem intentional shaping of the skull cap, however, can be seen as typical for the treatment of the Herxheim dead and cannot be attributed to violent conflicts. The results support the evidence gained from preliminary examinations of the Herxheim human remains and suggest a more complex view of the final phase of the Linear Pottery Culture (LBK) in southwest Germany.

FOCUS: The Scapula Representation could be the Key: A Further Contribution to the ‘Klasies Pattern’ Debate

Past discussion on the unusual skeletal part representations at Klasies River Mouth is briefly summarized. Recent discussion in this journal, regarding the “Klasies Pattern”, has focused upon the differential destruction of small and large bovid bone epiphyses by carnivore ravaging and density-mediated attrition. Bartram & Marean (1999) argue, from ethnoarchaeological study and consideration of other archaeological sites, that, unless shaft fragments are painstakingly identified, the upper limb bone epiphyses of large bovids will be seriously under-represented. They therefore suggest that the “Klasies Pattern” is likely to be artefact of taphonomic and analytical processes. Klein, Cruz-Uribe & Milo (1999) replied with a defence of the analytical procedures employed during the original Klasies River Mouth analysis. They also state that there was very little evidence of carnivore ravaging at Klasies River Mouth. In this paper, it is pointed out that Bartram & Marean's (1999) study only considered the humerus, radius, femur, tibia and metapodia. However, in the “Klasies Pattern” it is the scapula that is most notably abundant in the small bovid classes and most notably scarce in the large bovid classes. It is argued that, from the study of bone mineral densities and Brain's (1981) carnivore ravaging experiment, there is no reason to expect a differentially greater taphonomic destruction of large bovid scapulae. In fact, exactly the reverse may be true. It is therefore argued that at least this aspect of the “Klasies Pattern” must be considered to represent human differential bone transport, rather than an artefact of taphonomic processes.     

Archaeological Evidence for Cannibalism in Prehistoric Western Europe: from <Emphasis Type="Italic">Homo antecessor</Emphasis> to the Bronze Age

Archaeological studies of human cannibalism and its causes have never lacked controversy. The reasons for this are both the difficulties in identifying cannibalism and the inherent complexity, by the many nuances that can have the behaviour of eating other humans. After Turner’s detailed studies in the Southwestern USA, reports were published in the 1990s of cannibalism during European prehistory. Archaeological sites identified with cannibalism have been found that date from the early Pleistocene to the Iron Age. In this study, we review data from Western Europe’s prehistoric sites, which allow us to discuss the various labels that accompany interpretations of cannibalism. The most common interpretation is not ritual but is rather gastronomic, nutritional or dietary. However, there is no agreement on this interpretation. Following the data review, we propose dividing cannibalism into the following broad, objective and useful categories: exocannibalism, endocannibalism and survival cannibalism, although it is not always easy to choose one option. We also review the taphonomic characteristics of these assemblages, which enable us to establish the most common taphonomic markers of prehistoric cannibalism. These features include abundant anthropogenic modifications (on more than of 20 % of human remains), the intensive processing of bodies, greater abundance of cut marks related to defleshing and filleting that dismembering and the presence of human tooth marks or chewing marks.
