Seven species of marine bivalves, including six new taxa, are described from the Cape early Miocene Melville Formation which crops out on the Melville Peninsula, King George Island, West Antarctica. The bivalve assemblage includes representatives of the families Nuculidae, Ennucula frigida sp. nov., E. musculosa sp. nov.; Malletidae, Neilo (Neilo) rongelii sp. nov.; Sareptidae, Yoldia peninsularis sp. nov.; Limopsidae, Limopsis psimolis sp. nov.; Hiatellidae, Panopea (Panopea) sp. cf. P. regularis; and Pholadomyoida (Periploma acuta sp. nov.). Species studied come from four sedimentary sections measured in the upper part of the unit. Detailed morphologic features of nucloid and arcoid species are exceptionally well preserved and allow for the first time reconstruction of muscle insertions as well as dentition patterns of Cenozoic taxa. Known geological distribution of the species is in agreement with the early Miocene age assigned to the Cape Melville Formation. The bivalve fauna from Cape Melville Formation is the best known from Antarctic Miocene rocks, a time of complex geologic, paleogeographic and paleoclimatic changes in the continent. The new fauna introduces new taxonomic and palaeogeographic data that bear on the question of opening of sea gateways and distribution of Cenozoic biota around Antarctica. 相似文献

Five successive events can be widely recognized in the Tremadoc to early Arenig graptolite sequences of the world: 1, appearance of Dictyonema flabelliforme s.l. at the base; 2, appearance of Anisograptus; 3, appearance of Clonograptus and/or Adelograptus; 4, appearance of Temnograptus, Kiaerograptus, large Clonograptus and Tetragraptus; and 5, appearance of Tetragraptus approximatus at the base of the Arenig. The five events are used as a basis for distinguishing 5 successive graptolite assemblages and for correlating Tremadoc sequences. The most precisely and confidently correlated horizon is that of event 5, the appearance of T. approximatus; the next best is that based on event 4. Derivation of the biradiate Anisograptids, Clonograptus, and Adelograptus, from their presumed ancestor, Dictyonema flabelliforme, now appears to have passed through a stratigraphically, if not phyletically, intermediate stage represented by the triradiate Anisograptus, Triograptus and Bryograptus. 相似文献

The co-editors' introduction to this special issue of History and Anthropology outlines the rationale for featuring this collection of essays by social anthropologists and historians on medieval and early modern communities in Europe and Asia. After discussing basic terms and concepts in this endeavour, the introduction proceeds to address the comparative challenges implied in such transcontinental and cross-cultural forms of methodological practices. From here, the argument introduces this special issue's main division into three subsections, that is, (A) “Interdisciplinary Inspirations”, (B) “Cross-cultural Comparisons” and (C) “Transdisciplinary Intersections”. The text concludes with brief introductions to the contributing articles, and by a summary of the innovative conceptual and methodological results emanating from these forms of cooperation. 相似文献

The early Late Pleistocene late archaic human remains from Xujiayao, northern China, reveal several abnormalities of the neurocranial vault. The Xujiayao site is located on the northwestern boundary of the Nihewan Basin, and on the basis of various indicators, it dates to the early Late Pleistocene. Among the 15 human neurocranial elements found at Xujiayao in the 1970s, three elements show minor traumatic lesions of the external table: the largely complete Xujiayao 5a immature parietal bone, the Xujiayao 8 small piece of anterior right parietal bone and the Xujiayao 12 partial occipital bone. The lesions are all superior to the temporal or nuchal lines and hence were subcutaneous, covered only by the pericranium, the galea aponeurotica and the overlying skin. The external tables are variably concave with irregular bone within the bony depressions, and the diploë show varying degrees of involvement. The Xujiayao abnormalities join a series of minor neurocranial healed lesions among Pleistocene humans, as well as more pronounced healed neurocranial and facial trauma.

The Zhokhov site is one of the northern most archaeological sites in the world and a very ancient vestige of occupation of high latitudes by people, indicating that this territory was settled as early as about 8000 years ago. Investigation of the site began in 1989–1990 and then continued in 2000–2005. Here we consider the taphonomy, spatial distribution, species and age- and sex-related composition of the faunal remains from the Zhokhov site. These data allow conclusions regarding the subsistence strategy practiced by Zhokhov inhabitants, including the hunting tactics. This was a peculiar adaptation model based on reindeer and polar bear hunting in a 2:1 ratio. Reindeer hunting was all-seasonal, whereas polar bears were hunted mostly in winters at their dens. Mortality data for reindeer and polar bears depict the yearly subsistence cycle. The Zhokhov site is found to be a base camp occupied year-round with modest summer activities, while wintertime is characterised by intense polar bear hunting. Most reindeer were hunted in the fall. Subsistence strategy of the Zhokhov hunters was largely facilitated by the fact that at the time of occupation Zhokhov Island was still part of the coastal Siberian plain margin. 相似文献

This paper investigates changes in subsistence strategies at the upland cave site of Nugljanska (Croatia) at the end of the last ice age, during a time of rapid sea level rise and changing environment. We analysed the faunal assemblage from archaeological levels spanning the Pleistocene–Holocene transition (15,000–8000 years BP) and evaluated changes in relative abundance of species, measured species diversity, and compared the representation of terrestrial mammal and marine resources. We found a significant shift in the most abundant prey species exploited (from red deer, Cervus, to wild boar, Sus). There was some correlation between dietary diversification and periods of increased moisture availability and the spread of deciduous forest in the area. Our results suggest that there was a continuing reliance on terrestrial resources throughout time and that changes in dietary patterns were likely due to local environmental change and potentially, changing seasonal mobility strategies, at the Pleistocene–Holocene transition. 相似文献

At least 10 early Upper Paleolithic (EUP) open-air sites are found at Kostenki on the west bank of the Don River in Russia. During the 1950s, A.N. Rogachev excavated concentrations of horse bones and teeth from EUP layers at Kostenki 14 and 15 exhibiting the characteristics of kill-butchery assemblages. Excavations at Kostenki 12 in 2002–2003 uncovered a large quantity of reindeer and horse bones in EUP Layer III that also might be related to kill-butchery events, and the partial skeleton of a sub-adult mammoth excavated during 2004–2007 in EUP Layer V at Kostenki 1 yields traces of butchery. The character of these large mammal assemblages – combined with the analysis of artifacts and features – suggests that both habitation areas and kill-butchery locations are represented in a “EUP landscape” at Kostenki. 相似文献
