Two hominin incisor teeth from the middle Pleistocene site of Boxgrove, Sussex, England.

In 1995-1996 two isolated hominin lower incisors were found at the middle Pleistocene site of Boxgrove in England, with Lower Palaeolithic archaeology. Boxgrove 2 is a permanent lower right central incisor and Boxgrove 3 a permanent lower left lateral incisor. They were found separately, but close to one another and appear to belong to the same individual. The Boxgrove 1 tibia discovered in 1993 came from a different stratigraphic context and is thus believed to represent a different individual. This paper describes the morphology of the incisors, which is similar to other middle Pleistocene hominin specimens and, as with the tibia, suggests that they could be assigned to Homo heidelbergensis (recognising that the taxonomic status of this species is still a matter of debate). The incisors show substantial attrition associated with secondary dentine deposition in the pulp chamber and clearly represent an adult. They also show extensive patterns of non-masticatory scratches on the labial surfaces of both crown and root, including some marks which may have been made postmortem. The roots were exposed in life on their labial sides by a large dehiscence, extending almost to the root apex. This is demonstrated by deposits of calculus, polishing, and scratching on the exposed surfaces. The dehiscence may have been caused by repeated trauma to the gingivae or remodelling of the tooth-supporting tissues in response to large forces applied to the front of the dentition.

3-dimensional microscope analysis of bone and tooth surface modifications: comparisons of fossil specimens and replicas.

Cut-marks on fossil bones and teeth are an important source of evidence in the reconstruction of ancient butchery practices. The analysis of butchery marks has allowed archaeologists to interpret aspects of past subsistence strategies and the behavior of early humans. Recent advances in optical scanning microscopy allow detailed measurements of cut-mark morphology to be undertaken. An example of this technology is the Alicona 3D InfiniteFocus imaging microscope, which has been applied recently to the study of surface modifications on bones and teeth. Three-dimensional models generated by the Alicona microscope have been used to identify cross-sectional features of experimental cut-marks that are characteristic for specific cutting actions (e.g., slicing, chopping, scraping) and different tool types (e.g., metal versus stone tools). More recently, this technology has been applied successfully to the analysis of ∼500,000 year-old cut-marked animal bones from Boxgrove (U.K.), as well as cannibalized 14,700 cal BP year-old human bones from Goughs Cave (U.K.). This article describes molding methods used to replicate fragile prehistoric bones and teeth, where image quality was adversely affected by specimen translucency and reflectivity. Alicona images generated from molds and casts are often of better quality than those of the original specimen.

Upper Palaeolithic ritualistic cannibalism at Gough's Cave (Somerset, UK): The human remains from head to toe.

A recurring theme of late Upper Palaeolithic Magdalenian human bone assemblages is the remarkable rarity of primary burials and the common occurrence of highly-fragmentary human remains mixed with occupation waste at many sites. One of the most extensive Magdalenian human bone assemblages comes from Goughs Cave, a sizeable limestone cave set in Cheddar Gorge (Somerset), UK. After its discovery in the 1880s, the site was developed as a show cave and largely emptied of sediment, at times with minimal archaeological supervision. Some of the last surviving remnants of sediment within the cave were excavated between 1986 and 1992. The excavations uncovered intensively-processed human bones intermingled with abundant butchered large mammal remains and a diverse range of flint, bone, antler, and ivory artefacts. New ultrafiltrated radiocarbon determinations demonstrate that the Upper Palaeolithic human remains were deposited over a very short period of time, possibly during a series of seasonal occupations, about 14,700 years BP (before present). The human remains have been the subject of several taphonomic studies, culminating in a detailed reanalysis of the cranial remains that showed they had been carefully modified to make skull-cups. Our present analysis of the postcrania has identified a far greater degree of human modification than recorded in earlier studies. We identify extensive evidence for defleshing, disarticulation, chewing, crushing of spongy bone, and the cracking of bones to extract marrow. The presence of human tooth marks on many of the postcranial bones provides incontrovertible evidence for cannibalism. In a wider context, the treatment of the human corpses and the manufacture and use of skull-cups at Gough Cave have parallels with other Magdalenian sites in central and western Europe. This suggests that cannibalism during the Magdalenian was part of a customary mortuary practice that combined intensive processing and consumption of the bodies with ritual use of skull-cups.

New Results from the Examination of Cut-Marks Using Three-Dimensional Imaging

Abstract Cut-marks observed on fossil bones and teeth are an important source of evidence in the reconstruction of prehistoric butchery strategies. Micromorphological analyses of cut-marks have been shown to further the interpretation of hominin behavioural patterns. However, to date, the microscopic investigation of cut-marks has been limited to two-dimensional analyses or to the qualitative assessment of three-dimensional (3D) morphology. A new technology using the Alicona 3D InfiniteFocus imaging microscope reported here surpasses any current observational or microscopic method for the analysis of cut-marks. By creating a series of image planes and overlapping focus levels to construct a 3D composite image, vertical variations in the surface structure can be used to interpret differences in the mechanical impact caused by different types of tool and different butchery techniques. Three case studies are presented. The first describes cut-marks observed on the human anterior teeth from the Middle Pleistocene site of Boxgrove (West Sussex, England) which are interpreted as indications of two possible types of human behaviour: the use of the mouth as a third hand and postmortem treatment of the body. The second case study, an analysis of cut-marks on human remains at the Later Upper Palaeolithic (Magdalenian) site of Goughs Cave (Somerset, England), questions the interpretation of cannibalism previously accepted for this site by suggesting the hypothesis of burial ritual involving the butchering, but not the consumption, of human bodies. Finally, the butchery techniques adopted at Boxgrove and Goughs Cave are compared. This third study indicates that differences in the micromorphological characteristics of cut-marks reflect diversity in the type of tools used at these two sites.

Iberomaurusian funerary behaviour: evidence from Grotte des Pigeons, Taforalt, Morocco.

Grotte des Pigeons at Taforalt, north-east Morocco, is well known for a large assemblage of Iberomaurusian (Epipalaeolithic) skeletons, possibly representing the earliest and most extensively used prehistoric cemetery in North Africa. New archaeological excavations carried out in 2005 and 2006 revealed further human remains in a largely undisturbed burial area in an alcove at the back of the cave. This discovery provides the first opportunity to report on Iberomaurusian human mortuary activity at this site. Reported here are a closely spaced and inter-cutting series of four burials. These contained the remains of four adults, of which three were buried in a seated or slightly reclining position facing towards the cave entrance and one was buried in a highly flexed position on its left side. The distribution of articulated and disarticulated bones suggested intensive use of the area, with earlier burials disturbed or truncated by subsequent burials, and displaced skeletal elements deliberately or unwittingly incorporated into later depositions. Through this process, parts of a single skeleton were redistributed among several discrete graves and within the surrounding deposit. Some aspects of the Iberomaurusian funerary tradition that are evident from the human remains excavated in the 1950s are absent in the newly excavated adult burials, suggesting a possible elaboration of funerary activity over time.

Cannibalism versus funerary defleshing and disarticulation after a period of decay: comparisons of bone modifications from four prehistoric sites.

OBJECTIVES Humanly induced modifications on human and non-human bones from four archaeological sites of known funerary rituals (one interpreted as cannibalism and three interpreted as funerary defleshing and disarticulation after a period of decay) were analyzed to ascertain whether macromorphological and micromorphological characteristics of cut marks can be used to distinguish cannibalistic from secondary burial practices. MATERIAL AND METHODS Four collections were analyzed: the Magdalenian assemblage from Goughs Cave (UK) and the Mesolithic-Neolithic bone samples from Lepenski Vir, Padina and Vlasac (Serbia). A total of 647 cut marks (345 on human and 302 on non-human remains) were imaged and measured using an optical surface measurement system, the Alicona InfiniteFocus, housed at the Natural History Museum (London, UK). RESULTS The frequency of cut marks at Goughs Cave exceeds 65%, while it is below 1% in the Serbian sites, and no human tooth marks and only one case of percussion damage have been observed on the three Serbian collections. The distribution of cut marks on human bones is comparable in the four assemblages. Cannibalized human remains, however, present a uniform cut mark distribution, which can be associated with disarticulation of persistent and labile articulations, and the scalping and filleting of muscles. For secondary burials where modification occurred after a period of decay, disarticulation marks are less common and the disarticulation of labile joints is rare. The micromorphometric analyses of cut marks on human and non-human remains suggest that cut marks produced when cleaning partially decayed bodies are significantly different from cut marks produced during butchery of fresh bodies. CONCLUSIONS A distinction between cannibalism and secondary treatment of human bodies can be made based on frequency, distribution and micromorphometric characteristics of cut marks.

Sex differences in infant mortality in Spitalfields, London, 1750-1839.

This study examines sex differences in infant mortality in Spitalfields, London, and the estimated contribution of endogenous and exogenous factors to neonatal and infant mortality using the biometric model from 1750 to 1839. There was a marked decline in the risk of death during infancy and the neonatal period for both sexes during the study period. There was significant excess male infant mortality compared with that of females in the 1750-59 cohort, estimated from baptism and burial registers, but not in later cohorts. Similarly, males had higher neonatal mortality rates than females in 1750-59 but not in later cohorts. Biometric analyses suggest that the observed decrease in neonatal mortality in both sexes was caused by a reduction in both endogenous and exogenous causes of death. The contribution of maternal health and breast-feeding practices to the observed patterns of mortality is discussed in the light of available evidence.

Lost and found: the remarkable curatorial history of one of the earliest discoveries of Palaeolithic portable art

Reassessment of archives, early publications and the auditing of museum collections have often led to the discovery or rediscovery of long-forgotten specimens (e.g. Hollmann et at. 1986: 330; Fainer & Man-Estier 2011: 506, 520). The combination of initial poor recognition, insufcient scientic analysis and inadequate storage conditions, can cause the loss to science of important archaeological specimens. New analytical techniques may allow reconsideration of previous interpretations (e.g. P illon 2008: 720, 723-24; Hello et aZ. 2011; Higham et aZ. 2011: 522, 524) but in some cases it is the scientific value of a specimen that is not recognised at the moment of its discovery (e.g. Rosendahl et aZ. 2003: 277; Kaagan et aZ. 2011). Particularly revealing examples are those where the specimen found is the first of its kind. This was the case with the first handaxe recognised as manufactured by humans (Gamble & Kruszynski 2009: 468-70) or the rst two sets of Neanderthal fossil remains found respectively at Engis in 1829-30 and Gibraltar in 1848, which were not recognised as an early human species until after the 1856 discovery of _Neanderthal 1 at the Kleine Feldhofer Grotte in the Neander Valley near DUsseldorf, Germany (Stringer & Gamble 1993: 13). Similarly, lack of recognition caused the near loss of an engraved antler from the Magdalenian site of Neschers (France), possibly one of the first examples of Palaeolithic portable art.

An Engraved Human Bone from the Mesolithic–Neolithic Site of Lepenski Vir (Serbia)

Post-mortem manipulations of the body were common at Mesolithic–Neolithic sites along the Danube River. During assessment of disarticulated human remains from Lepenski Vir, an unusual set of incisions (notches) were observed on the diaphysis of a human left radius along with a few cut-marks. Very few studies have attempted to distinguish clearly the characteristics of these modifications. All incisions were examined using a Scanning Electron Microscope and a Focus Variation Microscope that generated measurable three-dimensional digital models. Our results indicate that, on the basis of their micro-morphometric features, qualitative and quantitative distinctions can be made between cut-marks and notches, a methodology which can be applied to other engraved bones. Cut-marks, accidentally produced during flesh removal, were more irregular, longer, narrower and shallower than the notches. The notches, produced by a ‘nick and slice’ motion (pressure was applied to the bone, then the tool was pulled in one direction), were deliberately engraved. This engraved human bone is a rare example within a Prehistoric European context, possibly a form of notation, marking or counting a series of (important) events.

An Upper Palaeolithic engraved human bone associated with ritualistic cannibalism

Cut-marked and broken human bones are a recurrent feature of Magdalenian (~17–12,000 years BP, uncalibrated dates) European sites. Human remains at Gough’s Cave (UK) have been modified as part of a Magdalenian mortuary ritual that combined the intensive processing of entire corpses to extract edible tissues and the modification of skulls to produce skull-cups. A human radius from Gough’s Cave shows evidence of cut marks, percussion damage and human tooth marks, indicative of cannibalism, as well as a set of unusual zig-zagging incisions on the lateral side of the diaphysis. These latter incisions cannot be unambiguously associated with filleting of muscles. We compared the macro- and micro-morphological characteristics of these marks to over 300 filleting marks on human and non-human remains and to approximately 120 engraved incisions observed on two artefacts from Gough’s Cave. The new macro- and micro-morphometric analyses of the marks, as well as further comparisons with French Middle Magdalenian engraved artefacts, suggest that these modifications are the result of intentional engraving. The engraved motif comfortably fits within a Magdalenian pattern of design; what is exceptional in this case, however, is the choice of raw material (human bone) and the cannibalistic context in which it was produced. The sequence of the manipulations suggests that the engraving was a purposeful component of the cannibalistic practice, implying a complex ritualistic funerary behaviour that has never before been recognized for the Palaeolithic period.
