Fossil coleoptera from Weichselian deposits at Voorthuizen, the Netherlands

Abstract

An account is given of fossil from two organic layers in Weischelian deposits at Voorthuizen, The Netherlands. On radiocarbon and stratigraphic evidence these beds apparently date from between the Brorup and Upton Warren interstadials. Although the samples analysed were small and gave meagre fossil assemblages, the lower bed clearly represents tundra conditions, with average July temperatures below 10°C. The upper bed gave a climatically nondescript fauna from which no firm inferences can be made. However, it is considered that had this bed been deposited under conditions as cold as those represented by the lower bed, the fossils would have given some indication of this, and it therefore seems likely that it reflects somewhat warmer conditions, with average July temperatures of about 10°C
