The application of microfossils in assessing the provenance of chalk used in the manufacture of Roman mosaics at Silchester

Microfossils recovered from chalk tesserae in mosaics from the Roman town of Calleva Atrebatum, modern Silchester, southern England, are used to suggest a provenance for the source-rock. The microfossils include foraminifera characteristic of late Cretaceous (Campanian) foraminiferal biozone BGS20 (quadrata macrofaunal biozone) and foraminiferal subzone BGS21i (basal mucronata macrofaunal biozone). Calcareous nannofossil assemblages from the same tesserae are poorly preserved, preventing precise age determination, but confirm an age of Santonian to Campanian. As indurated chalk beds of this age are not normally present in the stratigraphically higher chalks of southern England, it is probable that calcretised chalk, formed by secondary calcification beneath Palaeogene rock cover, was used to manufacture the tesserae. This suggestion is supported by a comparative analysis of chalk tesserae from the Norden Roman site in Dorset. Although the provenance of the chalk in some of the Silchester tesserae can be placed only within a broad geographical area of downland in southern England, others may have originated in the Dorchester–Swanage area, some 100 km to the southwest of Silchester, or the Portsdown area of southern Hampshire. None of the tesserae have been constructed from chalk found near Silchester.     

清代南部县衙档案中的差票考释

近三十年来,国内外学人在清代法制史的领域中,对州县司法审判程序的研究取得了一些成果,但对于这些司法程序中所涉及的具体档案资料,如状纸格式、戳记、状式条例、差票、堂审记录、保状、具结状等方面的个案研究则仍显不足.故本文拟对清代四川南部县衙门档案(以下简称<南部档案>)中的一则"差票"加以考释,以期有助于深刻认识清代地方法制等问题.     

巩义发现北宋石刻

2001年11月,巩义市清中村南地发现一尊北宋时期的圆雕石虎,石虎附近同时发现有大量的砖、瓦、瓷器残片等。河南省文物考古研究所与巩义市文物部门在清中村调查时又发现了两尊武士造像和两尊石虎石刻,这些石刻出土地点均属北宋皇陵的清易镇墓区范围,这些发现对进一步研究北宋皇陵公布提供了新的资料。

An investigation of the fractal properties of flint microwear images

This paper reports on an investigation into the fractal dimensions of flint microwear images which has been carried out in an attempt to resolve the existing controversy over the possibility of identifying microwear types from visual inspection of high magnification images, and describes a new method for flint microwear image analysis based on fractal geometry. Fractal dimensions of surface images, which are known to relate well to human visual perception of roughness, have been computed for various types of microwear. No significant correlations have been found between the fractal properties of the digital flint images and the contacted materials.     

“Random” hunting and the composition of faunal samples from archaeological excavations: A modern example from New Zealand

The ability of analyses of the age- and sex-composition of faunal samples from archaeological excavations to permit reliable inferences concerning prehistoric culling practices and, in particular, to distinguish between wild and domesticated animals is investigated by examining the demographic composition of 14 groups of red deer (Cervus elaphus) shot at random from a helicopter in the Southern Alps of New Zealand in early 1975. It is concluded that such “random” hunting can produce samples of bones that are apparently biased with respect to age and/or sex. The implications of these findings for prehistoric studies are discussed briefly with particular reference to the exploitation of red deer in Italy and Switzerland, and greater caution in excavating and analysing faunal samples is urged.
