The recovery and interpretation of microvertebrate bone assemblages from archaeological contexts

The analysis of microvertebrate remains recovered from buried contexts is frequently problematic for archaeologists. Diminutive size is a major obstacle to recovering, identifying, and interpreting microfaunal bone materials successfully. Their taphonomic history is often obscure, thus the significance of microvertebrate accumulations for settlement, subsistence, and ecological interpretation is difficult to evaluate. Recognizable and reliable archaeological signatures are sought for assessing the effect of taphonomic history on microvertebrate assemblages. Relevant signatures of bone damage, skeletal survivorship, taxonomic composition, and context are examined in assemblages produced and modified through accidental non-predator-related death, predator accumulation, and postmortem alteration.     

Bone surface modifications in zooarchaeology

Cutmarks made by stone tools, conchoidal flake scars from hammerstone percussion, carnivore tooth marks, striations from sedimentary abrasion, and other surface modifications on bones from archaeological sites constitute a crucial body of evidence for investigating the role of human behaviors and of nonhuman taphonomic processes in site formation. This paper describes the various kinds of bone surface modifications produced by humans and by nonhuman processes and assesses the current status of bone surface modification studies with regard to such issues as the need for greater analytical standardization, the selection of instruments for examining bone specimens, tactics for identifying the origins of marks on bones, and strategies for inferring human behaviors.     

Middle Holocene Taphonomy and Paleozoology at the Prairie-Forest Border,the Itasca Bison Site,MN

The Itasca Bison site near the prairie-forest border in central Minnesota is important to understanding the cultural and ecological role of bison in the upper Midwest during the middle Holocene. Recent reanalyses of this assemblage support the original interpretation of a taphonomically complex, fluvially modified site. Despite this taphonmic complexity, the role of humans in the butchering and possible accumulation of some of the bison fauna is also supported, although not as the only mechanism of accumulation. The bison assemblage is slightly biased toward males, and seasonality estimates are spread throughout the year. New direct accelerator mass spectrometry dates indicate a minimum of two highly mixed depositional events: one at 7970–7790 cal B.P. and an earlier event between 8520 and 8180 cal B.P.     

Modeling Breastfeeding and Weaning Practices (BWP) on the Coast of Northern Chile's Atacama Desert During the Formative Period

Stable isotope analysis of bone collagen is frequently employed as a means of studying the breastfeeding and weaning practices (BWP) of archaeological populations. Such studies are strengthened greatly through the application of statistical models that permit precise and model-bound estimates of weaning age, duration, trophic enrichment, and the isotopic characterization of supplementary foods. Here we present the result of a stable isotope (δ¹⁵N) and Bayesian computational modeling study of bone collagen from human subadults from two coastal cemetery sites located near the mouth of the River Loa in the Atacama Desert. Recent bioarchaeological and paleodemographic research on remains from these marine hunter-gatherer sites, which are contemporary with the Formative Period (1500 BC–AD 400), has found evidence for notably elevated rates of female fertility. Ultimately, we argue that the modeled BWP parameters, which indicate the early introduction of supplementary foods, support an argument of high fertility as gleaned from the bioarchaeological evidence, and that these results provide novel insights into the child-rearing practices of the coastal populations of the Atacama. Indeed, these populations would have seemed to have developed a set of BWP that carefully balanced the biological and economic production/reproduction of the community.     

Social Analysis of Mortuary Evidence in German Protohistoric Archaeology

German early historical archaeology has witnessed since the 1960s an intensive debate on the social analysis of mortuary remains. It started out with the question of archaeological criteria for the inference of social status in early medieval cemeteries. In the 1970s, attention shifted from quantitative to qualitative analyses of grave goods and to the use of data on labor investment and skeletal data. In the last decade or so, younger colleagues have tried to overcome the weaknesses of traditional inferences from grave goods (status, religion, ethnic affiliation) by looking at the implications of ritual, and new methods of analyzing biological kinship have been applied to identify families in prehistoric and early medieval cemeteries. The German debate shows similarities to as well as differences from the Anglophone debate. It is suggested that we may learn from these parallel developments, but we should also learn from the fact that two scholarly debates on the same subject could ignore each other for 3 decades.     

Human digestive effects on a micromammalian skeleton

This study describes the results of an experiment involving the consumption of a skinned, eviscerated, and segmented insectivore by an adult human male. Bone remains from recovered faecal contents are examined for skeletal element representation, breakage and digestive damage. Detailed examination of each category suggests severe skeletal attrition which is comparable to, and at times in excess of, the damage exhibited in microvertebrate skeletal accumulations originating from the scats of small mammalian carnivores.     

A New Find of a European Pond Tortoise,Emys orbicularis (L.) from The Netherlands: Osteology and Taphonomy

A recent find of a European pond tortoise is presented in relation to former finds of Pleistocene and Holocene age from the Netherlands. The new find, with a ¹⁴C date of 5400±70 years BP, allows for a detailed study of the carapace, plastron and skeletal elements contained within the complete shell.     

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.
