Estimating the magnitude of data asymmetry in palaeozoological biogeography

Palaeozoological data are asymmetrical because they indicate the presence of a species in the area in which its remains are recovered, but the absence of remains is not necessarily evidence for the absence of a species. It is impossible to measure the magnitude of data asymmetry with respect to biogeography, but the magnitude can be estimated. The proportion of sites in an area where a species is known to occur that have not produced remains of that species is an estimate of counter‐ubiquity. The proportion of identified faunal remains in an area where a species is known to occur that do not represent that species is another estimate of data asymmetry. Bivariate plots of the number of sites in an area that have produced remains of a taxon against the total number of faunal remains identified in the area indicate that data asymmetry can be estimated as the inverse of sample size. More sites and more identified faunal remains tend to produce more occurrences of a species, so more sites and more identified faunal remains will tend to provide a database that is not only more accurate but also less asymmetrical with respect to the geographical range of a species.

Understanding faunal contexts of a complex Tell: Tel Dor, Israel, as a case study

The complex stratigraphy of the large Levantine tells and the complexity of human behavior that took place on them, poses a major challenge in understanding site formation processes and their reflection in the faunal remains. We studied the contextual deposition of faunal remains in Tel Dor, as a model for complex tell sites, and the possibility of using faunal remains as a tool to distinguish between context types. In addition, we asked how can we use this knowledge to elucidate site formation processes. Our results demonstrate that most loci defined in the field as primary refuse or purposive disposal are indeed different from the loci defined as secondary refuse. Different types of contexts can be differentiated, to a degree, from one another based upon multivariate analysis of faunal remains. Statistical as well as spatial analyses may help elucidate site formation processes and the use of space. Bones can, and in many cases do, reflect primary activities. Lumping zooarchaeological data into a single ‘assemblage’, as done in most zooarchaeological studies today causes major loss of information. Consideration of the specific location of faunal remains can be used as further indication for context identity and for understanding specific activities in a site, with care this can be done even in complex sites such as the ‘urban mounds’ of the Levant.     

The Impact of recovery methods on taxonomic richness in Roman faunal assemblages

Recovery methods can affect species richness in faunal assemblages, which can in turn impact interpretations of diet. A comparison of sample size to species richness across faunal collections from screened and from unscreened deposits associated with Roman occupations clearly shows these influences. Not surprisingly, the rate of species input was higher for collections recovered using screening methods than for collections not recovered from screens. Syntheses of published data and comparative analyses of faunal assemblages must be cognizant of whether or not included assemblages were recovered using screens.     

Distribution parameters of guanaco (Lama guanicoe), pampas deer (Ozotoceros bezoarticus) and marsh deer (Blastocerus dichotomus) in Central Argentina: Archaeological and paleoenvironmental implications

In this paper we use non-ambiguous collections and sightings data from the 18th century to generate potential distribution models of three species of South American ungulates. These ungulates (Lama guanicoe -guanaco-; Ozotoceras bezoarticus -pampas deer- and Blastoceros dichotomus -marsh deer-) have different and specific environmental requirements. Through MaxEnt software, twenty-two environmental variables that characterize the distribution area of each species are defined. Once the models are generated, they are compared with the faunal associations found at Late Holocene archaelogical sites in order to infer paleoenvironmental conditions. We also discuss the role played by humans in the faunal associations which are "anomalous" or inconsistent with those models, like the spatial overlap of guanaco and marsh deer.     

Food for thought: using game cameras to better understand the movement of bones by scavenging in archaeological faunal assemblages

This paper questions our understanding of the movement of bones by animal scavengers in the archaeological record. Since assumptions regarding the effects of animal scavenging shape final interpretations of skeletal element frequencies in archaeological faunal assemblages, they are important for our understanding and reconstruction of ancient human behaviour. The results of a 4-year actualistic kangaroo scavenging study from Australia are used to question our understanding of the movement of the bone by contrasting visual data captured by motion-activated digital game cameras with traditional taphonomic studies using skeletal element frequencies. Game cameras are commonly used by ecologists to capture the behaviour of living species but have not yet been used in experimental archaeology where visually documenting animal scavenging behaviour can be used to understand the movement of carcasses and individual bones. Results suggest that traditional zooarchaeological analyses may not be accurate indicators of hunted versus scavenged prey in archaeological faunal assemblages. Moreover, they most certainly fail to document the entire suite of animals scavenging a carcass. These implications are discussed with particular reference to the ability to definitively ascertain the role of humans in the megafaunal extinction debate in Australia.     

Taphonomic resolution and hominin subsistence behaviour in the Lower Palaeolithic: differing data scales and interpretive frameworks at Boxgrove and Swanscombe (UK)

The identification of human butchery-signatures on fauna from Lower Palaeolithic sites is well documented and readily identifiable. Such bone surface modifications have the potential to provide not only information about past hominin meat-procurement behaviour but address the wider issue of competition for resources with other carnivore species. To understand and discuss these broader issues both hominin and natural bone surface modifications must be understood and contextualised within a site-specific spatial and temporal framework. This paper presents new results from faunal analysis at two key British Lower Palaeolithic localities: Boxgrove and Swanscombe. It illustrates that different depositional environments and excavation histories have resulted in different scales and resolutions of available data and hence in varying interpretive potentials. At Swanscombe the archaeological record has been disturbed by both fluvial activity and excavation history providing a coarser-grained record of anthropogenic behaviour than previously acknowledged. Conversely, at Boxgrove, a finer-grained, higher resolution record of human behaviours has been preserved; this, combined with both an extensive and intensive excavation strategy, has allowed for a broader discussion of hominin landscape use, resource competition and meat-procurement behaviour. This paper highlights that assessing the specific depositional environment at each site is crucial to understanding Palaeolithic faunal assemblage formation and, consequently, the available data-resolution and behavioural interpretation.     

Museum Collections and Archaic Era Vertebrate Faunal Remains from Cuba

ABSTRACT

Museum collections are an underutilised source of environmental archaeological data. Curated collections often contain faunal and floral remains that can be analysed using new methods and to address various research questions. For example, the broad patterns of Archaic or preceramic subsistence adaptations are not well known for the Caribbean region, and for Cuba in particular, due to the ecological variability among the islands and limited, quantified faunal data from radiocarbon-dated sites. To address these issues, we present quantified vertebrate faunal data and new radiocarbon dates from museum-curated collections from three Cuban sites. Las Obas, La Vega del Palmar, and Los Caracoles are Archaic, dating between roughly 350 BC to AD 630, although Vega del Palmar contains Pre-Arawak Pottery Horizon ceramics. The three assemblages include a diversity of taxa from several habitats, including various species of hutia (Capromyidae). The taxonomy of these rodents varies among the sites as do the proportions of other taxa. In addition to abundant hutia, the sites' occupants exploited an array of fish, birds, reptiles and other mammals, including manatee. We compare the sites faunal assemblages and discuss their ecological significance as well as their place in Cuban prehistory.     

Prehistoric Molluscan Faunas of the Yazoo River,Mississippi, USA: Archaeological Perspectives for Modern Conservation

Archaeological faunal assemblages can provide data valuable to modern conservation ecology. For example, while freshwater mussels (Bivalvia: Unionidae, Margaritiferidae) are common constituents in the archaeological record of North America, today they are one of the world’s most imperiled faunal groups. Efforts to aid habitat restoration, population growth, and species reintroduction can be informed by studies of prehistoric mussel assemblages. These data can provide a historical perspective, cataloging communities as they existed prior to extensive modern impacts, thus representing an ecological baseline to be compared with modern populations. This study focuses on two late prehistoric (ca. 300–600 AD) sites on the Yazoo River, where nearly 24,000 freshwater mussel valves were recovered. Though modern data are extremely limited for the river, analysis revealed it once supported a diverse mussel community containing numerous species currently considered rare, endangered, or extinct in Mississippi. In total, the combined shell assemblages yielded 23 new river records for the Yazoo River. One species in particular, Quadrula fragosa, represents the second such occurrence in Mississippi, and bolsters its candidate status as a new state record, as argued in a recent report from a neighbouring river in the Yazoo Basin.     

Hiding to eat: the role of carnivores in the early Middle Pleistocene from the TD8 level of Gran Dolina (Sierra de Atapuerca,Burgos, Spain)

Damage generated by large and small carnivores is common in many Middle Pleistocene sites. However, identifying the predator that produces the faunal accumulations is often a difficult task. In order to recognize the main type of carnivore that acts on a faunal assemblage, a combination of several characteristics should be taken into account: taxonomic and skeletal element representation, age profiles, carnivore damage (location, frequencies and dimensions of tooth-marks, bone breakage and digested bones), degree of fragmentation and frequencies of coprolites. But, adding environmental characteristics and the ethology of non-human predators/scavengers is also important. All these aspects are applied to the faunal assemblage from the TD8 level of the Gran Dolina site (Sierra de Atapuerca, Burgos, Spain). Paleomagnetic data combined with ESR and U-series place the TD8 level at the beginning of the Middle Pleistocene, specifically circa 700 kyr ago. The TD8 level contains a large faunal accumulation primarily composed of ungulate skeletal elements, and to a lesser extent carnivore remains. This assemblage is characterized by an overrepresentation of fallow deer (Dama vallonetensis), a skeletal profile biased towards cranial remains and limb bones, diversity of ages at death, a high proportion of carnivore damage and tooth-marks of large size, and an absence of human activity. According to these data, the accumulation seems to have been produced primarily by large carnivores, possibly hyenas. This observation does not rule out the possible occasional activity by other carnivores. Nevertheless, the characteristics of the TD8 assemblage do not correlate entirely with those traditionally used to define carnivore dens. In TD8, there are (1) no immature carnivore remains (remains of just one young Mosbach wolf); (2) scarce traces related to the end stages of consumption and some anatomical connexions; (3) few coprolites; (4) high proportion of adult ungulates and; (5) high quantities of whole bones and epiphyses. From this perspective, the TD8 faunal assemblage seems to correspond to a succession of carnivore occupations that allows the development of a suite of features to identify the activities of several species of predators that may have used the cave in different ways and durations. This study aims to emphasize the importance of these analyzes in order to know the behaviour of different non-human predators/scavengers in the European Middle Pleistocene sites.     

Horses,Hemiones, Hydruntines? Assessing the Reliability of Dental Criteria for Assigning Species to Southwest Asian Equid Remains

Many faunal assemblages across southwest Asia contain the remains of multiple wild equid species, which may reflect individual prehistoric human populations' use of different hunting and/or landscape exploitation strategies. Accurate equid species assignments are therefore important. This paper tests the extent to which zooarchaeologists agree on equid species assignments made using commonly used zooarchaeological dental identification criteria. Seven zooarchaeologists individually use published criteria to assign species to equid teeth from Neolithic Çatalhöyük in central Anatolia, then use Fleiss' kappa to measure our reliability of agreement. We assess our degrees of agreement for species assignments made using scanned images versus actual specimens and for mandibular teeth versus maxillary teeth. Having failed to achieve significant agreement, we conclude that zooarchaeologists should be cautious about species assignments made using these methods.

Isotopic palaeodiet studies of Ancient Egyptian fauna and humans

We report here stable carbon and nitrogen isotope results from human and faunal bone collagen from samples taken from sites in the Egyptian Nile Valley and surrounding region, dating from the Predynastic (c. 5500 BC) through to the Dynastic (c. 343 BC) periods. Isotopic values for the human population cluster together across this broad time range, with high δ¹⁵N ratios, and δ¹³C values indicating a largely C₃ based diet. The human data is not easily explained through comparison with our associated faunal data, and so may be explained by the consumption of protein from an ecosystem we did not adequately sample, such as freshwater fish or plants and fauna with unusually high δ¹⁵N values due to the extreme aridity of this region. The faunal isotopic data we did produce shows a great range in values between and within species, especially in cattle, and reflects the close proximity of three ecozones across a relatively narrow geographical area; the river, the immediate flood-plain area around the Nile and the desert surroundings.     

Middle Holocene fishing strategies in East Africa: zooarchaeological analysis of Pundo,a Kansyore shell midden in northern Nyanza (Kenya)

A zooarchaeological and taphonomic analysis is presented for the faunal remains from the Pundo shell midden in northern Nyanza province (Kenya), which contains Kansyore ceramics and dates to ca. 8000–7600 cal. BP. The faunal assemblage is overwhelmingly dominated by fish and molluscs, of which only the fish data are presented in detail. Taxonomic identifications suggest a diachronic change in relative species abundance, with cichlids becoming increasingly dominant, eventually comprising nearly 80% of the fish assemblage. The Pundo faunal data are compared with those from a number of other Kansyore sites. Pundo confirms that early Kansyore sites are purely forager sites, with domestic caprines only appearing at late Kansyore sites (post‐dating ca. 4400 cal. BP). Comparing ethological data for fish taxa found at Pundo and other lakeshore shell middens with those for fish taxa found at larger riverside sites, a seasonal round is suggested, in which short‐term fishing camps such as Pundo may have been occupied in the dry season, while riverside sites were probably occupied during the rainy season.

Do faunal remains reflect socioeconomic status? An ethnoarchaeological study among Central African farmers in the northern Congo Basin

Zooarchaeological analyses often draw inferences on socioeconomic status from the composition of bone assemblages associated with houses and other structures in residential sites. In this paper, we test how well faunal assemblages reflect socioeconomic differences among contemporary farmer households in two rural villages in the Central African Republic. Independent measures of wealth are tallied and ranked for six households in each village, including complete inventories of the types and numbers of material goods and the sizes of residential structures and agricultural fields. These data are compared against the associated food bones collected from household trash middens and activity areas, including skeletal abundances, large mammal body part representation, and taxonomic diversity. In most instances larger and more taxonomically diverse faunal assemblages are associated with houses of means and the faunas do, in fact, reflect differences in socioeconomic status. However, faunal “wealth” may be linked to factors unrelated to social or economic inequalities, notably the presence of active hunters. Our analyses suggest that small animals provide useful and important data in assessing socioeconomic means, and comparative studies of wealth in archaeological contexts should not be based on bones alone.     

BUTCHERING PATTERNS AND SPATIAL DISTRIBUTION OF FAUNAL ANIMAL REMAINS CONSUMED AT THE LOS MILLARES CHALCOLITHIC SETTLEMENT (SANTA FE DE MONDÚJAR,ALMERÍA,SPAIN)

The archaeological settlement of Los Millares (Santa Fe de Mondújar, Almería) is located in the Mediterranean coastal area of southern Spain. This archaeological site constitutes one of the most important settlements belonging to the Copper Age in the Iberian Peninsula and has given its name to the ‘millariense’ culture. The settlement has been completely excavated, yielding major archaeological faunal remains, with 27,426 bone fragments classified by researchers from Munich University (Germany). In this paper, we apply different statistical methods (mainly χ² analysis) to study the spatial distribution of bones from domestic and wild animals, reconstructing the patterns of appearance within specific functional spaces. These functions can be associated with meat consumption (sites to cut the animals into small pieces, areas where the meat was eaten, garbage sites, etc.) and the production of handmade objects (bone tools, stone tools, etc.). The results show different spatial distributions of faunal remains within the areas of the settlement, according to the animal species and particular parts of the animal skeleton, as well as the age and the sex of individuals. The findings reflect social behaviour that relates the consumption of certain species to a specific sector of population, and such behaviour can be discerned in the animal remains. Moreover, there is evidence regarding economic matters, such as meat production and the exchange of animals, which require further research.

Animal engravings in the central Sahara: A proxy of a proxy

The rock art of the central Sahara was created out of the beliefs, traditions and experiences of the engravers and painters. The animal engravings of the Wadi al-Ajal in south-western Libya are used to isolate some of the environmental and cultural/symbolic components that make up the pictorial record. A comparison between the depicted animals and the faunal remains recovered in the area identifies a number of characteristics. The engraving repertoire is dominated by a small number of frequently depicted animals that were of symbolic or economic importance to the engravers. Rare and singular depicted species extend this record to a diverse species spectrum. Although a preferential depiction of herbivores is evident in the data, there is a close match between faunal record and engravings which shows that all larger animals (over ca. 10 kg) that were present in the area were also depicted. The selection of animals in the rock art appears to reflect their visibility in the landscape while also providing a record of changing climatic conditions from savanna to desert habitats. The rock art therefore provides an indirect record of the local environment while also capturing the engravers' perception of animals and landscape.     

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.     

Looking for problems: A systems approach to hominin palaeocommunities from Plio‐Pleistocene Africa

This paper evaluates the potential contribution(s) of faunal analysis to hominin palaeoecology at regional and continental scales, through an explicit investigation of the values, methods and conceptual frameworks of palaeoanthropology and their compatibility with real data structures. It employs a problem‐framing method developed in policy‐relevant science to establish a suitable research design for ‘large scale’ faunal analysis, before testing the method in a pilot study of 48 faunal assemblages from the African Plio‐Pleistocene. Hitherto, taphonomic bias has discouraged attempts to study faunal assemblages on large spatiotemporal scales, and most scientists have restricted their work to the smaller (site or local) scale and/or a subset of the total fauna. Furthermore, palaeoanthropological studies of fauna tend to address pre‐determined questions through analysis of statistical outputs (patterns), rather than investigating the limitations and potential of the data through exploratory work. This paper, despite identifying a number of inherent constraints on palaeocommunity analysis at the large scale—including a clear tendency towards the segregation of faunal assemblages along taphonomic and geographic lines—successfully defines palaeocommunities and identifies systematic variation in their distribution in several regional datasets and at the continental scale. It suggests that the potential viability of faunal analyses for a given project could be made empirically testable, and further work on the lines defined here might provide insight into the impacts of taphonomy and ecology at the large scale. Although there are conceptual and methodological problems associated with large‐scale faunal analyses, this paper suggests that they could provide some insight into hominin environments, evolutionary ecology and biogeography as part of a holistic, multi‐scale approach to our lineages' history.

The use of statistical size estimations in minimum number calculations

Analyses of archaeological faunal assemblages often require the use of varied quantitative techniques for reconstructing aspects of the harvested populations. This is particularly important with the increasing use of zooarchaeological data outside of the realm of traditional archaeological inquiry. Detailed size estimations of archaeological faunal specimens can be used to distinguish between the remains of individual animals, aiding in the reconstruction of minimum number calculations. Statistical regression provides a particularly useful technique for generating size estimations which may then be used to calculate such modified MNI values. This paper outlines a methodology for utilising regression estimated sizes in MNI calculations, and tests the methodology in the context of a case study involving fish remains from Aleutian Islands archaeological sites. The use of this methodology to generate modified MNI values results in consistent increases over values calculated using traditional MNI approaches. Such an approach, while more costly in terms of required effort, is felt to be preferable to traditional approaches in contexts where detailed size estimations are usefully calculated to answer other research questions.

Identifying palaeo-environments and changes in Aboriginal subsistence from dual-patterned faunal assemblages,south-western Australia

Palaeo-environments and past human subsistence patterns are difficult to determine from dual-patterned faunal assemblages where human and non-human predators have accumulated and intensively modified animal bones. This paper examines such records in the Leeuwin–Naturaliste Region of south-western Australia, where a thin belt of coastal limestone contains caves and rock shelters with rich faunal deposits. The Late Pleistocene and Holocene part of this record derives from four archaeological sites: Devil's Lair, Tunnel Cave, Witchcliffe Rock Shelter and Rainbow Cave. Correspondence analysis combined with cluster analysis enables a preliminary assessment of habitat changes using simple species abundances in the faunal assemblages and comparison with indices of past human activity in the sites and the species’ present habitat preferences. These inferred changes, consistent with previous analyses of faunal remains and tree charcoal, suggest that late Holocene sites document Aboriginal occupation in coastal heath, scrub and woodland. Late Pleistocene deposits record hinterland occupation at times of low sea-level when the coast was up to 30 km seawards of its present position and the surrounding vegetation was open-forest or woodland. As rainfall increased and vegetation changed in the Holocene, species foraging in open-woodland declined or became locally extinct, while species requiring closed canopy habitats increased. Rank-order correlations of taxa and archaeological remains from depositional sequences before and after the environmental change indicate that the occupiers of late Holocene sites favoured the same generalist species that occupiers of Late Pleistocene sites had favoured, which were available at all times. Prey habitats, foraging behaviours and historic records of ethnographic hunting and settlement pattern suggest that this local continuity is consistent with maintenance of a “dispersive mode” subsistence pattern in the region.
