Fragmentation of Bird Bones in Food Remains of Imperial Eagles (Aquila heliaca)

Fragmentation of bird bones in pellets and uneaten food remains of imperial eagles (Aquila heliaca) was studied. The degree of fragmentation was higher than that produced by owls and lower than that in gyrfalcons. There were significant differences between pellets and uneaten remains in the survival of bones and their fragmentation. © 1997 by John Wiley & Sons, Ltd. Int. J.

Taphonomy of the bones of rodents consumed by Andean hog-nosed skunks (Conepatus chinga, Carnivora,Mephitidae) in central Argentina

The Andean hog-nosed skunks (Conepatus chinga) are generalized consumers. Rodents are a substantial part of their diet. In order to learn about the effects of this predator on the bones of the prey they consume, the bone remains from scats collected in La Pampa, Argentina, were analyzed from a taphonomic point of view. Analysis confirms that C. chinga produces severe destruction of bone remains, mainly during the chewing process. This allows inclusion of this predator in the category of extreme modifier of the bones of its prey. Data presented here and their interpretation provide criteria to identify the intervention of this predator in archaeological and paleontological sites.     

Fragmentation and preservation of bird bones in uneaten food remains of the Gyrfalcon Falco rusticolus

This paper presents fragmentation patterns of bird bones in uneaten food remains of the gyrfalcon Falco rusticolus. The victims' bones show a relatively low degree of fragmentation. Elements of the pectoral girdle and wing predominate while head and leg elements are poorly represented.     

Disentangling long bones of foxes (Vulpes vulpes and Alopex lagopus) from arctic archaeological sites

To discern the presence of two anatomically close species within an archaeological assemblage is always a problem for the analyst. A particularly interesting case is the distinction between the red fox (Vulpes vulpes) and the arctic fox (Alopex lagopus), which is often determined using non-rigorous criteria and producing results that must be regarded with caution. Classical methods for separating these two species and determining sexual dimorphism, and eventually the sex ratio, such as analyses using uni- and bivariate plots, are based on arbitrarily fixed limits between sexes. In this text, a more robust statistical method termed mixture analysis (MA) is used to determine the species of limb bones from foxes. First, the MA is applied to a sample of each species using metric data taken from a collection of present-day fox skeletons. Afterwards, the MA is applied to archaeological samples dated to the Dorset period and retrieved from the Tayara site (near Salluit, South Hudson Strait, Nunavik). The results clearly demonstrate that the greatest length (GL) of long bones, especially the humerus and tibia, is the best measurement for distinguishing the species, followed by the distal breadth and the proximal breadth; and that GL is better suited for sexing foxes. The results of MA applied to the Tayara site collection lead to the conclusion that the red fox is present along with the arctic fox among the assemblage, and that there is no fox body size change during the last two millennia in the Eastern Arctic.     

Taphonomic analysis of rodent bone accumulations produced by Geoffroy's cat (Leopardus geoffroyi, Carnivora,Felidae) in Central Argentina

Rodent prey remains recovered from Geoffroy's cat (Leopardus geoffroyi) scats were analyzed in order to identify taphonomic features produced by this predator. The analysis includes a year-long sampling discriminated by the seasons. Modifications produced by digestion are heavy. Taphonomic variables in samples discriminated by the seasons did not show major differences with respect to the total sample; thus, scats collected in any season clearly show the modifications on the bones of prey rodents made by Geoffroy's cats. The results presented here and its interpretation could be extrapolated to an analysis of zooarchaeological or paleontological assemblages.     

Morphometric and taphonomic analysis of granular ark (Anadara granosa) dominated shell deposits of Blue Mud Bay,northern Australia

Metrical analyses of complete mollusc shells have commonly been used to examine aspects of prehistoric mollusc demography, and by extension to investigate potential human exploitation of a variety of species. Recently it has been highlighted that several taphonomic processes, such as fragmentation, have the potential to introduce size bias into these archaeological samples, particularly towards smaller size classes, and thus the potential to significantly skew results of these metrical analyses. This is investigated here by deriving morphometric equations for the sand/mudflat bivalve Anadara granosa, a species prevalent in archaeological sites across northern Australia. A linear regression model based on a series of valve measurements, resulting in high coefficients of determination, demonstrates strong predictive power for size reconstruction. The effects of fragmentation on assemblages from two case study sites are then examined as a means of reviewing issues of differential size preservation, variation in mean valve size, and evaluating the strength of previous interpretations of intensive human exploitation in Blue Mud Bay. Based on these analyses it appears that A. granosa mean size is not significantly affected by fragmentation as other species described in the literature, and previous interpretations retain their validity.     

Neolithic Hedgehogs (Erinaceus europaeus) from the Island of Gotland show early contacts with the Swedish mainland

Previous research probing early migrations and contacts in the Baltic Sea area is characterized by the analysis of different chronologies and subsistent strategies on all sides of the Sea. Several studies performed on artifact typology, ceramics, grave rituals and physical anthropology ended with varying results. Although the question of human origins remains inconclusive, in this study, we rely on the phylogeography of an animal associated with humans to elucidate findings regarding prehistoric human migration and contacts.Hedgehogs, along with other fauna on Gotland, were brought over to the island by humans. We examined hedgehog mitochondrial DNA from the Pitted Ware Culture (Middle Neolithic). The genetic signatures of the animals on the island were investigated to determine the animal’s origin.From the 23 bones originally examined, twelve bones from all five locations studied yielded reliable results and resembled published extant Erinaceus europaeus sequences from Sweden, Norway and Denmark. We postulate that a western heritage for the Neolithic hedgehogs on Gotland indicates early human contact with the Swedish mainland.     

Starch grain characterization of Prosopis chilensis (Mol.) Stuntz and P. flexuosa DC,and the analysis of their archaeological remains in Andean South America

The fruit (pods) of Prosopis (Fabaceae) are frequently recovered from pre-Hispanic Argentinian archaeological sites, suggesting that this genus was of importance in ancient economies in this region. Yet it is only recently that archaeobotanists have begun to carry out systematic research into this genus. Therefore many questions remain to be addressed concerning the food value of Prosopis fruit, and its potential contribution. This paper examines starch from the pods of two species, Prosopis flexuosa and Prosopis chilensis, for the purposes of describing and classifying their morphological features and biometrical parameters. Pods of both species were gathered from two extremes (northern and southern) of the Hualfín Valley, Catamarca, Argentina. Starch abundance is estimated and compared with that of Zea mays, an economically important plant with high concentrations of starch. This paper reveals that Prosopis pods contain very low amounts of starch compared to starch-rich edible species. Despite this, the recovery of Prosopis starch grains can be successfully used to assess archaeological tool uses. Prosopis starch grains were found to be highly variable in shape. Grain size ranged between 10 and 20 μm. Granule irregularity and the high birefringence under polarized light are two of the most important diagnostic features. No significant statistical differences were found in the structure (morphology, size and hilum) of the starch of the same species from both localities. Finally, the implications for the role of this plant in past societies are discussed.     

Early and mid Holocene tool-use and processing of taro (Colocasia esculenta), yam (Dioscorea sp.) and other plants at Kuk Swamp in the highlands of Papua New Guinea

Recent multidisciplinary investigations document an independent emergence of agriculture at Kuk Swamp in the highlands of Papua New Guinea. In this paper we report preliminary usewear analysis and details of prehistoric use of stone tools for processing starchy food and other plants at Kuk Swamp. Morphological diagnostics for starch granules are reported for two potentially significant economic species, taro (Colocasia esculenta) and yam (Dioscorea sp.), following comparisons between prehistoric and botanical reference specimens. Usewear and residue analyses of starch granules indicate that both these species were processed on the wetland margin during the early and mid Holocene. We argue that processing of taro and yam commences by at least 10,200 calibrated years before present (cal BP), although the taro and yam starch granules do not permit us to distinguish between wild or cultivated forms. From at least 6950 to 6440 cal BP the processing of taro, yam and other plants indicates that they are likely to have been integrated into cultivation practices on the wetland edge.     

The hunted hunter: the capture of a lion (Panthera leo fossilis) at the Gran Dolina site,Sierra de Atapuerca,Spain

Many Pleistocene caves and rock shelters contain evidence of carnivore and human activities. For this reason, it is common to recover at these sites faunal remains left by both biological agents. In order to explain the role that carnivores play at the archaeological sites it is necessary to analyse several elements, such as the taxonomical and skeletal representation, the age profiles, the ratio of NISP to MNI, the anthropogenic processing marks on the carcasses (location and purpose of cutmarks and burning and bone breakage patterns), carnivore damage (digested bones, location and frequencies of toothmarks and bone breakage), length of the long bones, frequencies of coprolites and vertical distribution of the faunal remains, inter alia. From this, the documentation of carnivores in a faunal assemblage with a clear anthropogenic component can be understood from three main phenomena: (1) the carnivores as accumulators and the use of the site as a den; (2) carnivores as scavengers of hominid refuse and; (3) carnivores as hominids’ prey. Of these three phenomena, the last one is the least documented at the Middle Pleistocene sites. From this perspective, here we present the case of the anthropogenic use of a lion (Panthera leo fossilis) from level TD10-1 of Gran Dolina (MIS 9, Sierra de Atapuerca, Burgos, Spain). The lion bone remains show signs of direct interaction between this big cat and human groups that occupied Gran Dolina in these chronologies. From this perspective, the aim of this paper is to contribute to the knowledge of the role developed by large carnivores in the anthropogenic contexts and to provide data on human use of these predators at the European Middle Pleistocene sites.     

Black grouse as the prey of the golden eagle at an archaeological site

Remains of black grouse, Lyrurus tetrix, were recovered from an archaeological excavation of the site of a golden eagle, Aquila chrysaetos, eyrie. It has been suggested that bird remains from human predation can be distinguished from those due to avian predation, because humans leave few of the distal bones (tibiotarsus, carpometacarpus). In this case, the eagle also left few of these bones; it is suggested that the distinction is one which may allow owl prey to be distinguished, but human and raptor prey are indistinguishable by that criterion.     

First archaeozoological evidence for haimation, the ‘invisible’ garum

The fish remains are described that were found at the bottom of an Early Roman ceramic jar from Aila Aqaba, Jordan. The bones, representing the gill apparatuses of at least 33 medium-sized tunas (Auxis; Scombridae) and a single individual of a lizardfish (Trachinocephalus myops; Synodontidae), are believed to correspond to haimation. This highly prized fish sauce, documented previously only from ancient textual evidence, was typically made from the gills and the entrails of tunnids to which salt was added. The sauce was not imported from the Mediterranean or the Black Sea, but made from local Red Sea fish as shown by the zoogeographical distribution of the lizardfish that is considered as stomach content of the tunas. Because the fish bones were found in a locally produced jar and because the calculated volume of the haimation that the bones represent corresponds more or less to the volume of the jar, it is concluded that this high-quality garum was produced in this container at Aila itself.     

Spotted hyena (Crocuta crocuta) den use and taphonomy in the Masai Mara National Reserve,Kenya

Hyena taphonomy is of great importance to studies of hominid evolution, since these carnivore taxa have the highest potential both to produce large osseous assemblages and to modify existing hominid-accumulated assemblages throughout the Old World. The three extant hyena species (brown: Parahyaena brunnea; striped: Hyaena hyaena; and spotted: Crocuta crocuta) are all significant bone collectors and modifiers. Spotted hyenas generally have the lowest potential to accumulate osseous remains, and the rate of accumulation varies based upon the type of den. The present research examines the remains accumulated by spotted hyenas in Masai Mara Cave, Masai Mara National Reserve, Kenya. The contents of this den were collected twice by the authors, with an 11-year span interceding. The taphonomic signatures of spotted hyena interaction with bone are presented, including species and skeletal element representation, breakage patterns, tooth marks, tooth puncture, edge polish, and gastric corrosion. Other taphonomic factors examined include rodent gnawing and weathering stage. The cave den assemblage was accumulated at a rate of 30.4 identified specimens and a minimum of 4.1 prey individuals per year. In addition, the osseous remains accumulated by spotted hyenas at multiple burrow dens within the Reserve were examined for taxonomic representation and multiple taphonomic parameters. Rates of accumulation at this type of den tend to be very low, due to differential usage by spotted hyenas and the more ephemeral nature of earthen dens.     

Characterization of a current coprogenic sample originated by Canis lupus as a tool for identifying a taphonomic agent

We study a skeletal sample digested by Iberian wolf (Canis lupus signatus) in order to finding diagnostic features of digestion caused by this agent. The remains were taken from scats collected in different natural areas in the northwestern Iberian Peninsula. We tested different methods to recover the remains with the goal of not produce biases, and we evaluated the most appropriate methods. The results were compared with those reported by other authors who have also worked with samples digested by wolves. Bias during the procurement of the skeletal assemblages seems to be a significant cause of the differences observed between the samples. We found that it was necessary to fully recover all remains and individually analyze all modifications, even in small-sized remains. Taphonomic characterization was performed by analyzing physical and biochemical modifications. We believe that these results may be useful in the study of archaeological and paleontological assemblages.     

Reappraisal of ‘chronospecies’ and the use of Arvicola (Rodentia,Mammalia) for biochronology

The water vole, genus Arvicola, is characterised by a broad geographic distribution throughout Europe and is widespread during the late Middle and Upper Pleistocene. This genus is used as a major biostratigraphic tool within the Quaternary. Specific determinations using the Schmelzband-Differenzierung-Quotient or SDQ have identified many chronospecies within the fossil species Arvicola cantiana (Hinton, 1910). As SDQ calculation remains limited, this study reappraises the Arvicola genus in terms of morphodiversity and morphospace using outline analysis which takes into account the tooth as a whole. Outline analysis suggests that one single species of Arvicola, A. cantiana, was present during the Pleistocene. This species shows great variability with no trends or patterns in morphospace. Thus, these results call into question the reliability of SDQ for specific determinations and throw doubt on the biochronological framework based on Arvicola.     

Late Pleistocene Crocuta crocuta spelaea (Goldfuss, 1823) clans as prezewalski horse hunters and woolly rhinoceros scavengers at the open air commuting den and contemporary Neanderthal camp site Westeregeln (central Germany)

Late Pleistocene Ice Age Crocuta crocuta spelaea ( Goldfuss, 1823) hyenas from the open-air gypsum karst site Westeregeln (Saxony-Anhalt, central Germany) is dated into the early to middle Late Pleistocene. Hyena clans apparently used the karst for food storage and as “commuting den”, where typical high amounts (15% of the NISP) of hyena remains appear, also faecal pellets in concentrations for den marking purposes. Additionally small carnivores Meles, Vulpes and Mustela appear to have used some cavities as dens. Several hundreds of lowland “mammoth steppe fauna” bones (NISP = 572) must have been accumulated primarily by hyenas, and not by Neanderthals at the contemporary hyena/human camp site. Abundant caballoid horse remains of “E. germanicus Nehring, (1884)” are revised by the holotype and original material to the small E. c. przewalskii horse. Woolly rhinoceros Coelodonta antiquitatis remains are also abundant, and were left in several cases with typical hyena scavenging damages. Rangifer tarandus (11%) is mainly represented by numerous fragments of shed female antlers that were apparently gathered by humans, and antler bases from male animals that were collected and chewed in few cases (only large male antlers) by hyenas. The large quantities of small reindeer antlers must have been the result of collection by humans; their stratigraphic context is unclear but such large quantities most probably resulted from schamanic activities. The hyena site overlaps with a Middle Palaeolithic Neanderthal camp, as well as possibly with a later human Magdalénian site.     

Rats cannot have been intermediate hosts for Yersinia pestis during medieval plague epidemics in Northern Europe

The commonly accepted understanding of modern human plague epidemics has been that plague is a disease of rodents that is transmitted to humans from black rats, with rat fleas as vectors. Historians have assumed that this transmission model is also valid for the Black Death and later medieval plague epidemics in Europe. Here we examine information on the geographical distribution and population density of the black rat (Rattus rattus) in Norway and other Nordic countries in medieval times. The study is based on older zoological literature and on bone samples from archaeological excavations. Only a few of the archaeological finds from medieval harbour towns in Norway contain rat bones. There are no finds of black rats from the many archaeological excavations in rural areas or from the inland town of Hamar. These results show that it is extremely unlikely that rats accounted for the spread of plague to rural areas in Norway. Archaeological evidence from other Nordic countries indicates that rats were uncommon there too, and were therefore unlikely to be responsible for the dissemination of human plague. We hypothesize that the mode of transmission during the historical plague epidemics was from human to human via an insect ectoparasite vector.     

The Scandinavian reindeer (Rangifer tarandus L.) after the last glacial maximum: time,seasonality and human exploitation

Antlers and bones of reindeer (Rangifer tarandus L.) are the most frequently found vertebrate remains from the Late Glacial deposits of Southern Scandinavia. The Danish collection now consists of more than 350 specimens and of these 47 have been radiocarbon dated extending the range of occurrence in the area with ca. 1300 ¹⁴C yr. Thus the first occurrence is pushed back to ca. 12?500 ¹⁴C yr BP (late Bølling chronozone) while the youngest date lies at ca. 9200 ¹⁴C yr BP (late Preboreal chronozone) establishing that the reindeer survives well into the Holocene. The seasonal dates of the reindeer indicate for the first human occupation (the Havelte group from the Bølling period) a summer, autumn and early winter occupation, with reindeer, as well as man, apparently being absent during the coldest winter months. Finally, it is shown that Southern Scandinavia acted as a calving area throughout the Late Glacial and Early Holocene thus discrediting the North–South model of reindeer groups moving from a wintering area in Southern Scandinavia to a calving area in the foothills of the North European plain.     

First dendroarchaeological dates of prehistoric contexts in South America: chullpas in the Central Andes

Despite the existence of long-lived tree species with excellent tree-ring characteristics, the use of dendrochronological techniques for dating archaeological contexts has been very limited in South America. Recent research in the Bolivian Altiplano of the Central Andes has yielded a network of Polylepis tarapacana chronologies that goes back to the 13th century. This species was regularly used by local populations since pre-Columbian times as raw material for beams, lintels, hooks and other architectural features in houses, storage chambers, and sepulchers. The aim of this study is to argue in favor of the potential of P. tarapacana for providing high resolution dates of significant archaeological events during the pre-Columbian era. The chronology of chullpas (burial towers and storage chambers) in the southern Andean Altiplano is used as a case study. Growth rings from P. tarapacana have provided several centennial-length dendrochronological records including a reference regional chronology covering the last 786 years in the Central Andean highlands. Based on this long reference chronology calendar years were assigned to woody pieces from pre-Hispanic chullpas. Dendroarchaeological results are consistent with contextual evidence and most radiocarbon dates from woody samples and related archaeological items. Our results indicate that P. tarapacana has a high potential for providing annually-resolved tree-ring dates for archaeological contexts in the Altiplano since the early 13th century.     

First evidence of Equus asinus L. in the Chalcolithic disputes the Phoenicians as the first to introduce donkeys into the Iberian Peninsula

Two equid species have been documented in the Pleistocene of the Iberian Peninsula, the horse Equus caballus, and the Eurasian hemione Equus hydruntinus. While the former survived the Holocene–Pleistocene until now, the timing for the extinction of the latter is unclear. Scarce, fragmented archaeological remains assess the presence of small equids living in the Holocene of Iberia. Those could possibly correspond to the Eurasian hemione although unambiguous morphological identification is often not possible. With the find of an equid tooth from Leceia, a Chalcolithic fortified site in Portugal, and using both morphological and mitochondrial genome analyses, we demonstrate for the first time the presence of a new equid species in Holocene Iberia, namely a donkey (Equus asinus). Radiocarbon dating of the tooth to Cal 2340–2130, and 2080–2060 BC with 95% probability, demonstrates that donkeys were present in Iberia well before the arrival of Phoenicians in the first quarter of the first millennium BC (900–750 years BC), which were considered so far as the first who introduced donkeys in the region.
