Abstract

A detailed palynological investigation has been undertaken of the Upper Devonian and Lower Carboniferous succession in the Barnstaple area of north Devon, southwest England. The succession consists of the marginal marine Baggy Formation which passes upwards conformably into the marine Pilton Formation. Age determinations are based on twelve moderate to well preserved miospore assemblages. The assemblages are assigned to the miospore zonation scheme of Higgs et al. (1988) which was established for the late Devonian and Tournaisian rocks of Southern Ireland. The Baggy Formation ranges in age from the uppermost Devonian LL-LE Biozones, while the Pilton Formation shows a change in the palynoflora from uppermost Devonian LN Biozonal age to Basal Carboniferous VI Biozonal age. The Devonian-Carboniferous Boundary has been accurately located in the Upper Pilton Formation at Fremington Pill.
