Avian resource depression or intertaxonomic variation in bone density? A test with San Francisco Bay avifaunas

Previous analyses of the Emeryville Shellmound fauna suggested that ever-expanding late Holocene human populations of the San Francisco Bay area depressed a wide range of vertebrate taxa, including cormorants (Phalacrocorax), geese (Anserinae), and large shorebirds (e.g., Numenius, Limosa). Far-reaching implications for prehistoric human behavior, historical ecology, and modern conservation biology have resulted from that work. We test the generality of the bird-based conclusions here by documenting temporal trends in avifaunal abundances from five additional sites located on the San Francisco Peninsula. Analyses of these data reveal patterns identical to those found at Emeryville, showing significant declines through time in the relative abundances of both geese and cormorants between about 2000 and 700 B.P. New photon absorptiometric-based density data for cormorants, geese, and ducks (Anatinae) are used to determine if the declines through time in the relative abundances of geese and cormorants are correlated with variation in the extent of density-mediated attrition observed in these faunas. The data and analyses presented here suggest that while density-mediated attrition played a role in structuring element abundances in these avifaunas, there is no evidence that it varied systematically through time to produce the revealed patterns in taxonomic abundances. Resource depression thus remains a viable hypothesis for the declining abundances of large-sized waterbirds during the late Holocene of the San Francisco Bay region. The new bone density data we present should be useful to analyses of archaeological and paleontological avifaunas wherever these or related taxa are found around the world.     

Sea level rise or shallow-water midden deposition? Archaeopedology at the Seminole Rest archaeological site,coastal East-Central Florida

Sedimentological and faunal studies at the Seminole Rest archaeological site on the Atlantic coast of Volusia County, FL, addressed the question of whether construction of the large shell mound at the site began on dry land or in the shallow waters of Mosquito Lagoon. Particle-size analysis defined a sand body beneath the hardshell clam mound, which is bordered by mucky tidal marsh and the shallow, silty lagoon. Weathered kaolinite, hydroxy-interlayer vermiculite, and gibbsite clays in the sub-mound sediments, identified by X-ray diffraction, contrasted with the ‘shrink-swell’ smectite clays of the tidal marsh and mound periphery and corroborated the particle-size evidence of a sand bar or bank. The presence in the sub-mound sediments of articulated valves of the diminutive Brown Gem Clam (Parastarte triquetra, Family Veneridae), and their absence in the silty marsh sediments, presented another line of evidence for a sand body beneath the mound. Parastarte is a common inhabitant of shallowly submerged sand bars. The existence of articulated valves of all size classes below the mound argues for a thriving population of the clams in their preferred habitat at the onset of mound deposition, which would have begun in the shallow water adjacent to the shore and not on dry land.     

Breed character or pathology? Cattle with loose horns from the Eneolithic site of Hostivice–Litovice (Czech Republic)

Archaeological finds of a ritual character from Hostivice–Litovice are classed as Eneolithic cattle burials (depositions). One pit from the Funnel Beaker Period (Baalberge group; ca. 3800–3500 BC) contained a subadult bovine skeleton, whose skull bore loose horns (scurs) while still alive. This type of horn, which is movable or possibly hanging, is known from recent breeds and is caused by a special combination of alleles on two locuses and its phenotypic expression is sexually specific. However, this can also be simply a pathological state (teratology, atrophy, dysplasia or fractures), possibly caused by deliberate deformative manipulation on the horns. Such manipulations are known from recent breeding as well as from the prehistory. Both possible causations of this unique find from Hostivice–Litovice and related finds of hornlessness are discussed.     

Unusual burial from an early Neolithic site of the lengyel culture in central Poland: Punishment,violence or mortuary behaviour?

During excavations at the Early Neolithic site of the Brześć Kujawski Group of the Lengyel Culture in Osłonki (central Poland), an atypical burial of an adult male was discovered. The individual's skeleton revealed traces of several perimortem injuries: both broken shins (the right shin with two fractures), a large fracture to the frontal bone and about 25 cut marks made with a flint blade in the parietal‐occipital region of the cranium on the left side. The arrangement of the fractured parts of the lower limbs might suggest that the injuries were intentionally exposed. Due to the relatively rich grave goods, it seems unlikely that the buried person was rejected by the community and thus killed or stigmatized by mutilation of the cadaver. The way the cuts were made is different from the cases of scalping or severing muscles in cannibalistic or mortuary practices known from the literature. This burial probably reflects some special funerary rite, which is now difficult to reconstruct or interpret. It is both possible that the observed injuries resulted from wounds that led to the individual's death (perhaps in circumstances that motivated the other special features of the burial) or that they were inflicted on the dead body. Taking into account the probable practices of dismembering of the dead body or human sacrifice found in the later Neolithic period in Poland, all of these possibilities may be considered with respect to this burial.

Which Benjamin Franklin—Yours or mine? Examining responses to a new story from the historical archaeology site of Franklin court

Resumen La reciente revisión de las campa?as arqueológicas llevadas a cabo en la mansión de Benjamín Franklin en Filadelfia (excavada entre 1953 y 1975) revelan una nueva hístoría muy significativa para las comunidades que viven en la actualidad en Estados Unidos. La historia de Franklin, inicialmente poseedor de esclavos y posteriormente abolicionista da un giro completo cuando, en sentido figurado, los descendientes de la comunidad Afro-americana, por cuya libertad Franklin luchó, excavan la historia de Franklin para crear un lugar de culto para la memoria histórica nacional. Así mismo se ha encontrado una nueva historia relevante para los Nativos Americanos, el Movimiento de los Trabajadores, las mujeres y los colectivos de gays y lesbianas. A la luz de un contexto más amplio que engloba varias temas colectivos se analizan las diversas respuestas a estas nuevas interpretaciones.

Résumé Une récente évaluation de l'archéologie effectuée sur le site de la demeure de Benjamin Franklin à Philadelphie (déterrée 1953–1975) révèle l'interprétation d'une nouvelle histoire d'intérêt aux communautés modernes des Etats-Unis. L'histoire de Franklin, d'abord propriétaire d'esclaves puis devenu abolitioniste est révolue lorsque les descendants de la communauté afroaméricaine que Franklin s'est évertué à libérer, fouillent l'histoire de Franklin pour la création d'un monument à la mémoire nationale historique. On trouvera aussi des faits nouveaux d'intérêt pour les Américains natifs, sur le mouvement travailliste, sur les femmes et les homosexuels. On examine de nouvelles réponses sur ces sujets à la lumière des contextes plus ouverts à la base des programmes communautaires.

     

Global human impacts or climate change?: explaining the Sooty Shearwater decline at the Minard site,Washington State,USA

Sooty Shearwater (Puffinus griseus) remains decrease throughout the occupation (AD 1000–1600) of the Minard site (45-GH-15) on the southern Washington coast, USA. Given that New Zealand is one of the major breeding locations for this long-distant migrant, the decline at the Minard site may be due to human impacts on a global scale. In particular, the Maori practice of muttonbirding, the killing and preparation of fledgling shearwaters for storage, may have affected the number of summer migrants reaching the Pacific Northwest Coast. A second hypothesis attributes the decline in Sooty Shearwaters at the site to increasing sea surface temperatures and/or increased frequency of ENSO events during this period. Understanding how Sooty Shearwaters responded to human hunting and/or climate events in the past may be useful for the current management of this species, which has faced dramatic declines in recent decades.     

Burning wood or burning bone? A reconsideration of flotation evidence from Upper Palaeolithic (Gravettian) sites in the Moravian Corridor

This paper compares archaeobotanical and other data from new excavations at two Upper Palaeolithic sites — Dolní V?stonice II and P?edmostí I — in the Moravian Corridor, Czech Republic. Both contain the traces of broadly contemporary ‘Gravettian’ occupations during the warmer episodes of the Pleistocene which preceded the last glacial maximum. Yet their archaeobotanical remains show striking differences — those from Dolní V?stonice II being dominated by large quantities of conifer wood charcoal, while those from P?edmostí I are much more scanty and dominated by vitrified plant remains, in association with large quantities of burnt bone. We argue that these differences between these two datasets arise from different uses of fuel at either site: bone at P?edmostí I and wood at Dolní V?stonice II. Subsequently, we explore the possible reasons for this difference and argue that once likely taphonomic distinctions are accounted for, these data on fuel use offer fresh insights into the functions and durations of these Upper Palaeolithic occupations of the Moravian corridor and some possible implications for how archaeobotanical data from such sites should be interpreted.     

Stray cats: Pets or pests? Cats and kittens everywhere in the medieval harbour site of Qalhāt (Oman)

The discovery of numerous cat remains, including many kittens, in various buildings (i.e., domestic house, cistern, mosque) of the ancient harbour of Qalhāt in Oman is unique among faunal assemblages in the medieval Arabian Peninsula. In this study, a zooarchaeological and taphonomic analysis (ageing, skeletal element distribution, pathologies) is conducted to understand the origin of the cats and to deepen our understanding of human–cat relations. Thus, concerning the cats found in Qalhāt, two hypotheses may explain their presence: they took refuge in one of the buildings and died in situ before the complete destruction of the structures, or the corpses may have been dumped in the structures during a phase of their abandonment, very likely for health reasons.
