An integrated microcrinoid zonation for the lower Campanian chalks of southern England, and its implications for correlation

Detailed logging, sampling and processing of Lower Campanian chalks in Sussex, Hampshire, Isle of Wight, Wiltshire and Dorset (United Kingdom) have revealed the presence of a distinctive succession of pelagic microcrinoid faunas, including 25 species and forms of the order Roveacrinida.
