A Pleistocene chronology for the fauna and artefacts of Cow Cave, Devon, UK
نویسندگان
چکیده
Cow Cave is a well-known archaeological and palaeontological site in the wall of Chudleigh Gorge, Devon, England. The cave is choked after a short distance with allochthonous sediments and speleothem accumulations. Palaeontological excavations at the cave in 1927 to 1935, and again in 1962 to 1963, yielded a rich Pleistocene fauna and several stone tools. However, in the absence of radiometric dating, the faunal composition was ambiguous with respect to age. Here, we report the first radiometric dates on the site. Two Thermal Ionization Mass spectrometric uranium series disequilibrium dates place a critical speleothem layer from within the Cow Cave sediments in the warmer intervals of the MIS 6 glacial period, and suggest that the basal sediments entrained a fauna and human artefacts from the preceding MIS 7 interglacial period, the Aveley.

The significance of the subterranean fauna in biogeographical reconstruction: examples from Cape Range peninsula, Western Australia
Cape Range peninsula contains a diverse troglobite (obligatory cave inhabitants) fauna, the only rich troglobite community known in Western Australia and in the semi-arid tropics. At least thirtyeight species of troglobite (or stygobiont) in this sparsely sampled area place it amongst the worlds faunistically diverse karst areas. The characteristics of the region and its subterranean fauna are ...

The oldest known spatially-explicit archaeological excavation, conducted in Brixham cave, Devon, in 1858, is reconstructed using geographic information systems technology. Two dimensional plots of individual fossil taxa and flint artefacts demonstrate the utility of the technique for elucidating taphonomy and palaeobiology.The cave served as a den for hibernating brown bears, as a den for hyena...

The Tennessee River Basin is considered one of the most important regions for freshwater biodiversity anywhere on the globe. The Tennessee River Basin currently includes populations of at least half of the described contemporary diversity of extant North American freshwater fishes, crayfish, mussel, and gastropod species. However, comparatively little is known about the biodiversity of this bas...
متن کاملFirst record of the root vole Microtus oeconomus (PALLAS, 1776) (Arvicolidae, Rodentia, Mammalia) in Croatia – fossil remains from the Late Pleistocene of Vindija Cave
Late Pleistocene remains of Microtus oeconomus (PALLAS, 1776), a species that is not any more a member of the extant fauna of Croatia, have been recently found in Vindija Cave sediments. The sample of 21 teeth shows a slight increase of M1 length and decrease of A/L ratio within the cave sequence from older (G complex; 32 to 42 ka) towards younger strata (E+F complex; layer E is dated at ca. 18...
متن کاملFaunal assemblage seriation of southern African Pliocene and Pleistocene fossil deposits.
Fossil assemblages from the Pliocene and Pleistocene of southern Africa were seriated in order to give a better idea of their relative chronology. Time-sensitive mammals were selected for calculation of the Faunal Resemblance Index among 17 site units. On the basis of a logistical seriation and subsequent site analysis, the following sequence of sites was deemed most probable: Makapansgat Membe...
