Abstract
Newly discovered non-marine bivalve bands and other fossiliferous horizons, re-collection of some known horizons and re-examination of museum material from an inland section covered over for many years are utilized to correlate the succession at Westward Ho!. A non-marine bivalve band at Westward Ho! is correlated with one in the late Namurian of South Wales. The dated strata range from the late Namurian, very probably late R 1c in Cycle 3 of the Bideford Group, to the lower part of the Communis Chronozone in Cycle 9, which includes the Cornborough Sandstone and overlying ‘Culm Bed’. The adjacent Greencliff Beds, which have yielded a marine trace fossil, are briefly discussed and their structure is re-interpreted. They may possibly be of an earlier age than the Bideford Group. The Westward Ho! sequence, when compared with those of nearby Clovelly and Bude to the southwest, reveals stratigraphical gaps and lacks five black shale horizons with major goniatite bands. The possible significance of these differences in the Westward Ho! succession is briefly discussed.
