Does the choice of a reference matter for log size index analysis? A case study from roman times in southern France

Log Size Index (LSI) has been developed and used in archaeozoology to perform biometric studies of often small datasets, a recurrent limitation of archaeological faunal assemblages. This approach consists of aggregating measurements taken on different anatomical parts by standardisation, using a reference to which the studied measurements are scaled. No consensus exists in the choice of the reference to be used for LSI analyses and several datasets are now available, differing in their specimens and variables composition, and geographic and temporal origin. Using a biometric dataset of 5533 measurements of cattle, suids, sheep and goat from southern France and dated from the Roman times we compared the use of several references, provided by the R package zoolog, with a ‘mean’ reference specifically built for our studied sample and that corresponds to an averaged specimen. We demonstrated that references differ both in their raw measurements and their allometries, and that the choice of the reference influences the number of variables and measurements that can be analysed, but also diachronic LSI analyses and potentially their interpretations. While the main patterns are similar among references, local variation exist and it could not be excluded that the choice of the reference will more strongly influence other studies. We advocate to use the mean of the studied archaeological assemblage as reference, with the double benefit of exploiting to the maximum the number of available measurements, and of minimising, on average, the possible allometric differences between the studied population and the reference.

Beyond Chronology, Using Bayesian Inference to Evaluate Hypotheses in Archaeology

ABSTRACTArchaeologists frequently use probability distributions and null hypothesis significance testing (NHST) to assess how well survey, excavation, or experimental data align with their hypotheses about the past. Bayesian inference is increasingly used as an alternative to NHST and, in archaeology, is most commonly applied to radiocarbon date estimation and chronology building. This article demonstrates that Bayesian statistics has broader applications. It begins by contrasting NHST and Bayesian statistical frameworks, before introducing and applying Bayes's theorem. In order to guide the reader through an elementary step-by-step Bayesian analysis, this article uses a fictional archaeological faunal assemblage from a single site. The fictional example is then expanded to demonstrate how Bayesian analyses can be applied to data with a range of properties, formally incorporating expert prior knowledge into the hypothesis evaluation process.

Macroscopic Chop Mark Identification on Archaeological Bone: An Experimental Study of Chipped Stone, Ground Stone, Copper, and Bronze Axe Heads on Bone

This paper presents a new macroscopic method for identifying chop marks on archaeological faunal assemblages and highlights the major differences in the morphology of chop marks created by stone and metal axes. The method provides macroscopic criteria that aid in the identification of both complete and incomplete chop mark types as well as the raw material of the axe. Experiments with modern stone (chipped and ground) and metal (copper and bronze) axes found that the degree of fragmentation within a chop mark is related to both the width and sharpness of the axe and can be classed on a scale from 1–5 using a variety of criteria. The experiments demonstrate that sharp chipped stone axes are fragile (often break upon impact) and do not create clean and well-defined chop marks. Ground stone axes are more durable but tend to create very fragmented chop marks without a clean cut (sheared) surface. Unalloyed copper metal axes can create sheared chopped surfaces; however, the relatively soft metal creates more crushing at the point of entry than bronze axes. In contrast, bronze axes are durable and create chop marks with exceptionally low rates of fragmentation resulting in a clean-cut sheared surface that extends into the bone for more than 3 mm. The method is applied to the faunal assemblage from the Early Bronze Age site of Göltepe, Turkey to determine whether the chop marks on bones were made by stone or metal axes at this early metal processing settlement. The results suggest that many of the chop marks were made by metal implements (e.g., axes). Hence, this method provides another means to monitor the adoption rates of new raw materials at a time when both metal and stone axes coexisted.

Who’s eating pork? Investigating pig breeding and consumption in Byzantine, Islamic and Norman/Aragonese Sicily (7th-14th c. AD)

This paper investigates the culture of pork consumption in Sicily by examining a number of archaeological faunal assemblages dated to chronological phases spanning from the Byzantine to the Norman/Aragonese period (7th-14th c. AD). Zooarchaeological analyses reveal substantial diachronic changes in the use of the main domesticates, particularly concerning pig frequencies. In the Islamic period (9th-11th c. AD), pig is poorly represented at urban sites; this is likely to reflect a socio-cultural acceptance of the Islamic religious precepts forbidding pork consumption. By contrast, and in continuity with the Roman and Byzantine periods, pigs are well-represented in rural settlements, thus indicating a more resilient attitude of these communities toward newly imported religious traditions. In the later Norman/Aragonese period, the frequency of pig increases at some urban sites, reflecting the fact that that pork prohibition had been lifted and that new food production and consumption practices were developed. Pig continues, however, to be almost absent at a number of urban sites and castles/fortified villages; this may suggest the persistence of Islamised communities in Sicily after the end of Islamic rule.

Characterization of structural changes in modern and archaeological burnt bone: Implications for differential preservation bias.

Structural and thermodynamic factors which may influence burnt bone survivorship in archaeological contexts have not been fully described. A highly controlled experimental reference collection of fresh, modern bone burned in temperature increments 100-1200˚C is presented here to document the changes to bone tissue relevant to preservation using Fourier transform infrared spectroscopy and X-ray diffraction. Specific parameters investigated here include the rate of organic loss, amount of bone mineral recrystallization, and average growth in bone mineral crystallite size. An archaeological faunal assemblage ca. 30,000 years ago from Tolbor-17 (Mongolia) is additionally considered to confirm visibility of changes seen in the modern reference sample and to relate structural changes to commonly used zooarchaeological scales of burning intensity. The timing of our results indicates that the loss of organic components in both modern and archaeological bone burnt to temperatures up to 700˚C are not accompanied by growth changes in the average crystallite size of bone mineral bioapatite, leaving the small and reactive bioapatite crystals of charred and carbonized bone exposed to diagenetic agents in depositional contexts. For bones burnt to temperatures of 700˚C and above, two major increases in average crystallite size are noted which effectively decrease the available surface area of bone mineral crystals, decreasing reactivity and offering greater thermodynamic stability despite the mechanical fragility of calcined bone. We discuss the archaeological implications of these observations within the context of Tolbor-17 and the challenges of identifying anthropogenic fire.

Magdalenian and Epimagdalenian chronology and palaeoenvironments at K\u016flna Cave, Moravia, Czech Republic

Kůlna Cave is the only site in Moravia, Czech Republic, from which large assemblages of both Magdalenian and Epimagdalenian archaeological materials have been excavated from relatively secure stratified deposits. The site therefore offers the unrivalled opportunity to explore the relationship between these two archaeological phases. In this study, we undertake radiocarbon, stable isotope (carbon, nitrogen and sulphur), and ZooMS analysis of the archaeological faunal assemblage to explore the chronological and environmental context of the Magdalenian and Epimagdalenian deposits. Our results show that the Magdalenian and Epimagdalenian deposits can be understood as discrete units from one another, dating to the Late Glacial between c. 15,630 cal. BP and 14,610 cal. BP, and c. 14,140 cal. BP and 12,680 cal. BP, respectively. Stable isotope results (δ13C, δ15N, δ34S) indicate that Magdalenian and Epimagdalenian activity at Kůlna Cave occurred in very different environmental settings. Magdalenian occupation took place within a nutrient-poor landscape that was experiencing rapid changes to environmental moisture, potentially linked to permafrost thaw. In contrast, Epimagdalenian occupation occurred in a relatively stable, temperate environment composed of a mosaic of woodland and grassland habitats. The potential chronological gap between the two phases, and their associations with very different environmental conditions, calls into question whether the Epimagdalenian should be seen as a local, gradual development of the Magdalenian. It also raises the question of whether the gap in occupation at Kůlna Cave could represent a change in settlement dynamics and/or behavioural adaptations to changing environmental conditions.

Macromammal and bird assemblages across the late Middle to Upper Palaeolithic transition in Italy: an extended zooarchaeological review

Evidence of human activities during the Middle to Upper Palaeolithic transition is well represented from rock-shelters, caves and open-air sites across Italy. Over the past decade, both the revision of taphonomic processes affecting archaeological faunal assemblages and new zooarchaeological studies have allowed archaeologists to better understand subsistence strategies and cultural behaviors attributed to groups of Neandertal and modern humans living in the region.This work presents the preliminary results of a 5-years research programme (ERC n. 724046 – SUCCESS) and offers a state-of-the-art synthesis of archaeological faunal assemblages including mammals and birds uncovered in Italy between 50 and 35 ky ago. The present data were recovered in primary Late Mousterian, Uluzzian, and Protoaurignacian stratigraphic contexts from Northern Italy (Grotta di Fumane, Riparo del Broion, Grotta Maggiore di San Bernardino, Grotta del Rio Secco, Riparo Bombrini), and Southern Italy (Grotta di Castelcivita, Grotta della Cala, Grotta del Cavallo, and Riparo l'Oscurusciuto). The available Number of Identified Specimens (NISP) is analysed through intra- and inter-site comparisons at a regional scale, while aoristic analysis is applied to the sequence documented at Grotta di Fumane. Results of qualitative comparisons suggest an increase in the number of hunted taxa since the end of the Middle Palaeolithic, and a marked change in ecological settings beginning with the Protoaurignacian, with a shift to lower temperatures and humidity. The distribution of carnivore remains and taphonomic analyses hint at a possible change in faunal exploitation and butchering processing between the Middle and Upper Palaeolithic. A preliminary comparison between bone frequencies and the distribution of burned bones poses interesting questions concerning the management of fire. Eventually, the combined use of relative taxonomic abundance and aoristic analysis explicitly addresses time averaging and temporal uncertainty embedded in NISP counts and offers estimates of absolute change over time that can be used to support hypotheses emerging from taxon relative frequencies.

Animal Remains from Ritual Sites: A Cautionary Tale from the Eastern Adriatic

AbstractThis article assesses the potential pitfalls of extant methods and criteria used for identifying the ritual use and consumption of animals. Previous analysis of the Late Iron Age sanctuary assemblage from Spila Nakovana identified the ritual consumption of domestic animals in the sanctuary through comparison with a common set of criteria for the identification of ritual patterning in faunal assemblages. A recent analysis of a larger sample from Spila Nakovana has overturned this original determination, leading to a re‐evaluation of the ranked importance of the common criteria utilised for ritual patterning identification. The importance of context is addressed in the determination of ritual patterning within archaeological faunal assemblages, with regard to both the direct and wider context of the sample.

STABLE OXYGEN ISOTOPE SOURCING OF ARCHAEOLOGICAL FAUNA FROM CHACO CANYON, NEW MEXICO

Modern datasets provide the context necessary for accurate interpretations of isotopic data from archaeological faunal assemblages. In this study, we use the oxygen isotope ratios (δ18O) of modern small mammals from Chaco Canyon, New Mexico, to quantify expected isotopic variation in a local population. The δ18O values of local, modern small mammals encompass a broad range (−6.0‰ to 4.8‰ VPDB), which is expected given the extreme seasonal variation in the δ18O of precipitation on the Colorado Plateau (−11‰ to −3‰ VPDB). Isotopic ratios of small mammals obtained from excavated archaeological sites in Chaco Canyon (ca. AD 800 to 1200) show no significant differences with their modern counterparts, suggesting that there is no difference in the origins of the archaeological small-mammal collection and the modern, local Chaco Canyon small-mammal collection. In contrast, δ18O values of large mammals from Chaco archaeological sites are significantly different from those of modern specimens, reflecting a nonlocal, but also nonspecific, source in the past.

A preliminary application of dental cementum incremental analysis to determine the season-of-death of equids from the Xujiayao site, China

Seasonality study of Paleolithic archaeological faunal assemblages is important for reconstructing modes of animal death and ancient hominin strategies for prey acquisition. The dental cementum of animal teeth records the season of an individual animal in which it died, providing the necessary evidence for determining any patterns in season of death. This article presents the procedure and preliminary results of the application of cementum incremental analysis to equid teeth, which comprise the dominant component of the fauna from the Xujiayao Site—an early Late Pleistocene archaeological site in China. Results show multi-seasonal use in both the upper and lower layers of this site. Furthermore, attention is given to the method’s future application in seasonality studies at Paleolithic archaeological sites in China.

Zonkey: A simple, accurate and sensitive pipeline to genetically identify equine F1-hybrids in archaeological assemblages

Horses, asses and zebras, can produce first-generation F1-hybrids, despite their striking karyotypic and phenotypic differences. Such F1-hybrids are mostly infertile, but often present characters of considerable interest to breeders. They were extremely valued in antiquity, and commonly represented in art and on coinage. However, hybrids appear relatively rarely in archaeological faunal assemblages, mostly because identification based on morphometric data alone is extremely difficult. Here, we developed a methodological framework that exploits high-throughput sequencing data retrieved from archaeological material to identify F1-equine hybrids. Our computational methodology is distributed in the open-source Zonkey pipeline, now part of PALEOMIX (https://github.com/MikkelSchubert/paleomix), together with full documentation and examples. Using both synthetic and real sequence datasets, from living and ancient F1-hybrids, we find that Zonkey shows high sensitivity and specificity, even with limited sequencing efforts. Zonkey is thus well suited to the identification of equine F1-hybrids in the archaeological record, even in cases where DNA preservation is limited. Zonkey can also help determine the sex of ancient animals, and allows species identification, which advantageously complements morphological data in cases where material is fragmentary and/or multiple candidate equine species coexisted in sympatry.

Analysis of fracture patterns from experimentally marrow-cracked frozen and thawed cattle bones

Pre-breakage treatment of bones affects fracture mechanics and bone-breakage patterns. Understanding the results of various treatments leads to a more objective interpretation of archaeological faunal assemblages. Little is known about the specifics of fracture pattern differences between frozen and thawed bone, which is important in the context of studying potential frozen meat caches. This study reports the results of experiments performing hammerstone bone-breakage on frozen and thawed cattle femora and humeri with the periosteum and a thin layer of muscle meat left intact. Results indicate that the frozen or thawed state of the bone influenced the extent and type of fracture and resulting fragments. These differences potentially allow for the macroscopic identification of frozen and thawed marrow-cracked bones from an archaeological assemblage or scavenging site.

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.

Using a 3-stage burning categorization to assess post-depositional degradation of archaeofaunal assemblages: Some observations based on multiple prehistoric sites in Australasia

The role of degradational processes that act on archaeological faunal assemblages after burial has attracted less attention than it warrants, in part because many of the changes take place over time scales that are not amenable to experimental investigation. We propose a straightforward method for evaluating the level of post-depositional degradation in a stratified archaeological faunal assemblage based primarily on trends in the burning composition of the assemblage. The twin foundations of the method are: 1) the experimentally verified changes in physical properties that occur in bone as it is progressively burned through carbonized to calcined stages: and 2) postulated contrasts between burning stages in susceptibility to a suite of degradational processes that operate in the burial context, including a range of microbial, fungal, thermal and chemical processes. We present data from seven archaeological sites from Australasia and three ethnographic assemblages from Papua New Guinea, including sites in open-air, rockshelter and cave contexts, and sites with both acidic and alkaline soil conditions. Each of the archaeological sites is treated as a temporally-seriated assemblage that documents the potential impacts of post-depositional degradation on the faunal assemblage. We compare the relative abundance of unburned, burned/carbonized or calcined bone through each sequence and identify commonalities of pattern that are highly suggestive of post-depositional degradation. For each assemblage, these patterns are verified by visual inspection and identification of classic signs of surface degradation such as pitting and root channelling. In each of the acidic contexts there was a clear trend of increasing degradation of bone with excavation depth (= age). Assemblages from alkaline deposits were more complex, but some also provided more subtle evidence of degradation within the profile. Investigation of burning profiles in combination with careful examination of bone macro-damage provides a useful tool for identifying the pattern of post-depositional degradation within a stratified sequence and for distinguishing this from other various kinds of taphonomic patterning, and from signals produced by human behaviour.

Economic utility and nutritional value of the Common wombat (Vombatus ursinus): Evaluating Australian Aboriginal hunting and butchery patterns

The Common wombat (Vombatus ursinus) is Australia's largest extant quadruped herbivorous marsupial, yet little is known about its potential economic and dietary value in the archaeological record. In the rich late Pleistocene archaeological faunal assemblages in southwest Tasmania dated to between 35,000 to 13,000BP, the wombat is the second most common prey species after the medium-sized macropod, the Bennett's wallaby (Macropus rufogriseus). Detailed analysis of one of these sites, Kutikina Cave, indicates that the head, pectoral region (including anterior axial elements) and forelimbs of the wombat were frequently selected by people, whilst the ‘meaty’ pelvic girdle and hindlimbs were largely underrepresented. This differs to the patterns observed for the Bennett's wallaby where the large hind region dominates, and the anterior part of the animal is rare in the archaeological assemblage. To investigate this discrepancy in the distribution of wombat body parts, an economic utility and nutritional analysis was conducted and the results compared to the range of wombat skeletal elements from the late Pleistocene faunal assemblage from Kutikina Cave, southwest Tasmania. The results suggest that Tasmanian Aboriginals predominately bought back the meat closer to the brain to the cave and either ignored or consumed the rest of the animal away from the site. Furthermore, a high fat content surrounding the pectoral girdle and vertebral column was identified, which may also have influenced the selection of this region. While evidence of marrow extraction from wombat long bones has been recorded in the faunal assemblage at Kutikina Cave, it was found that these elements do not provide the same quantity or quality available from the Bennett's wallaby. These results have implications for understanding prey selection and butchery strategies of these late Pleistocene hunter-gatherers, especially during the height of the Last Glacial Maximum.

Pleistocene and Holocene palaeoclimates in the Gebel Akhdar (Libya) estimated using herbivore tooth enamel oxygen isotope compositions

The palaeoclimate of the Gebel Akhdar massif, in Cyrenaica, northeast Libya, is investigated using the stable oxygen isotope ratio (δ18O) of herbivore tooth enamel from the archaeological faunal assemblages of the Haua Fteah and Hagfet ed Dabba caves. Samples accumulated through human activity at the sites, thus climatic interpretations are in direct chronological association with periods of human presence in the local landscape. Wild Ammotragus lervia (Barbary sheep) and Bos sp. (auroch), and domestic Ovis sp. and Capra sp. from the Levalloiso-Mousterian (≥73.3–43.5 ka) to the Neolithic (∼9.3–5.4 ka) cultural phases are analysed. Results indicate that the most arid environment represented by the samples occurred at ∼32 ka, when populations associated with Dabban lithic assemblages were present within the region. Climatic instability increased during oxygen isotope stage 2. Consistent with other palaeoenvironmental investigations in the Gebel Akhdar, there is no evidence for hyper-arid events during the last glacial and surface water, most probably in the form of local springs, was available throughout the time periods considered. Overall, results indicate that different cultural groups occupied the Gebel Akhdar landscape under different climatic conditions, but that climate variations appear to have been of lower magnitude than those that occurred at inland North African locations. These reconstructions provide further support to the theory that the Gebel Akhdar may have served as a refugium for human populations in North Africa during times of global climatic extremes.

A new methodological approach to the taphonomic study of paleontological and archaeological faunal assemblages: a preliminary case study from Olduvai Gorge (Tanzania)

Here we present a new analytical method that classifies bone damage patterns objectively and mathematically via a morphotypic definition (taphotype) of each long limb element and a bootstrapped correspondence analysis. This enables statistically-based classification and interpretations. The accuracy of these interpretations depends on the accuracy of the analogical frameworks applied. The new method shows that bone damage patterns differ according to carcass type and size. They also differ depending on environmental conditions (captive and wild carnivores). The method is also useful to detect the type of carnivores involved in the modification of epiphyseal portions. This opens the door to interpretations of hominin–carnivore interactions and the resulting strategies of carcass acquisition strategies by hominins. The application of the method to a sample of epiphyseal portions from two archaeological sites from Olduvai Gorge (BK and FLK N) shows its potential resolution. BK has been previously interpreted as a hominin–carnivore assemblage, whereas FLK N has been interpreted as a felid-accumulated assemblage. The new method confirms these interpretations.

A refined protocol for calculating MNI in archaeological molluscan shell assemblages: a Marshall Islands case study

Comprehensive and transparent protocols for calculating Minimum Number of Individuals (MNI) for archaeological faunal assemblages are critical to data quality, comparability, and replicability. MNI values for archaeological molluscan assemblages are routinely calculated by counting a select range of Non-Repetitive Elements (NREs). Most commonly, only the frequency of the spire of gastropods and the umbo or hinge of bivalves are recorded. Calculating MNI based only on the frequency of these NREs can underestimate the relative abundance of particular molluscan shell forms. Using archaeological mollusc assemblages from two sites in the Marshall Islands as a case study, we outline a new protocol (tMNI) that incorporates a wider range of NRE and calculates MNI based on the most frequently occurring NRE for each taxon. The principles that underlie the tMNI method can be modified to be regionally or assemblage specific, rather than being a universally applicable range of NRE for the calculation of MNI. For the Marshall Islands assemblages, the inclusion of additional NRE in quantification measures led to (1) a 167% increase in relative abundance of gastropods and 3% increase in bivalves (2) changes to rank order abundance, and (3) alterations to measures of taxonomic richness and evenness. Given these results for the Marshall Islands assemblages, tMNI provides more accurate taxonomic abundance measures for these and other archaeological molluscan assemblages with similar taxa. These results have implications for the quality of zooarchaeological data increasingly utilised by conservation biologists, historical ecologists and policy makers.

Species identification of archaeological marine mammals using collagen fingerprinting

Throughout human history, coastal and marine resources have been a vital part of human subsistence. As a result archaeological faunal assemblages from coastal sites often contain large quantities of skeletal remains indicative of human interaction with marine mammals. However, these are often hard to identify due to a unique combination of factors regarding the procurement, utilisation, morphological and physical characteristics of marine mammal bones. These factors often result in a large number of archaeological cetacean and pinniped specimens fragmented beyond visual recognition, being labelled ‘whale’ or ‘marine mammal’. In this paper we report the development of a Zooarchaeology by Mass Spectrometry (ZooMS) method of collagen fingerprinting, for efficient and low cost discrimination of a wide range of marine mammal species including cetaceans and pinnipeds. We apply the technique to more than fifty archaeological specimens from seven different North Atlantic sites ranging from the Mesolithic until the Early Modern period.
