A vertebra of a Brown Bear (Ursus arctos) is described from the Mesolithic settlement Star Carr. This is the first record of the species from the site. The presence of Brown Bear in a Preboreal/Boreal deposit is an important addition to the early Mesolithic fauna of Britain. A comparison with contemporary Danish material shows that the bone from Star Carr falls within the wide size range of the Danish subfossil Brown Bear. In Denmark the species decreases in number from Boreal to Atlantic time, and finds are extremely scarce in Britain during the same time interval. This is probably due to the major eustatic sea level rise, which isolated Britain and Sjælland, preventing new immigration, and to vegetational changes restricting the preferred habitats of the Brown Bear.  相似文献

Domestic ovicaprine specimens, some attributed specifically to Ovis aries L., have been recovered at two Mesolithic sites in the western Languedoc region of France, and two sites in southeastern France. The sites are typical late Mesolithic occupations, firmly dated between 7300 BP and 8000 BP, and stratigraphically precede the appearance of other domestic animals, cultivated plants, pottery, and the establishment of settled villages in their regions. They seem to represent early steps in the adoption of animal husbandry by hunter-gatherer societies in the western Mediterranean. Evidence from the Aude valley sites is presented for the gradual development of animal herding over a period of 1000 years or more, which spans the Mesolithic-Neolithic boundary. The evidence suggests that indigenous Mesolithic societies may have played a formative role in the development of settled farming communities in this area, and that the availability of domestic species may not have led rapidly to major changes in settlement, economy and society.  相似文献

The technique of growth-line analysis is used to examine seasonal growth patterns in modern specimens of the edible cockle, Cerastoderma edule L. The modern control work provides a basis for the interpretation of seasonal collection in archaeological cockles, and is applied to shells from the Mesolithic site of Morton, Fife. The seasonal use of the site is shown to be clearly related to site function.  相似文献

Charred plant remains from the mesolithic site of Roc del Migdia have been analysed in detail. Hazel shell and endocarp fragments of sloe (Prunus spinosa L.) have been identified by incident light microscopy and an attempt has been made at the identification of quantities of parenchymatous plant remains through the use of the scanning electron microscope. A number of different classes of tissue are described and the implications of the results discussed.  相似文献

Evidence of cereal type pollen grains in the pre-elm decline sections of pollen profiles is demonstrated from five sites in Ireland and three in Britain. Technical and archaeological considerations are also discussed. It is concluded that cereal cultivation in the British Isles occurred before the traditional beginnings of arable activity as denoted by the elm decline, and that the palynological data should be seen to underline caution in referring pre-elm decline pollen changes to Mesolithic disturbance.  相似文献

Through ethnographic accounts, the method of heat treatment of silica materials to improve the flaking qualities is shown to have been known almost worldwide. Some mesolithic and neolithic flint artifacts from southern Sweden were examined in order to determine if they too were heat treated. From several methods proving or indicating thermal alteration of flint, analysis using scanning electron microscopy was chosen. Two samples were taken from each artifact, one being examined unaltered, the other being heat treated. No two samples from the same artifact had the same kind of surface appearance. Thus these analyses prove that the artifacts examined had not been heat treated.  相似文献

Bones of adult and juvenile aurochs (Bos primigenius Boj.) from the refuse of a Mesolithic settlement, Ulkestrup Lyng Øst (c. 6090 BC), are examined. The problem of estimating the ontogenetic age of the younger animals is dealt with in order to establish the time of the year at which they were killed and thereby the possible season of hunting.The age-determination is mainly based on tooth-wear, which is discussed in its relationship to physiological changes in the stomach, that are correlated with the dietary changes from milk to solid food. The subfossil mandibles are compared with modern material from domestic calves and with other Danish subfossil calves' mandibles.  相似文献
