Head, M.J., 1996; Late Cenozoic dinoflagellates from the Royal Society Borehole at Ludham, Norfolk, eastern England. Royal Society Borehole at Ludham, Norfolk, eastern England. Journal of Paleontology 70(4), 1996: 543-570 Abstract - Restudy of upper Pliocene (ca. 2.4-1.8 Ma) and possible lower Pleistocene dinoflagellates from the Royal Society borehole at Ludham, eastern England has revealed the presence of more than 29 dinoflagellate species, substantially revising earlier records of this important locality. Assemblages reflect climates that fluctuated within a warm- or mild-temperate to cool range, as shown by the discovery that specimens earlier assigned to the warm-water Tectatodinium pellitum all belong to a cool-water element comprising Bitectatodinium tepikiense, Filisphaera filifera, F. microornata, and Habibacysta tectata. This element appears to have been widely mistaken for Tectatodinium pellitum in coeval deposits of the North Sea basin and beyond. The following are among several species reported for the first time from coeval deposits of the North Sea basin: Filisphaera filifera, F. microornata, Operculodinium? eirikianum, O. giganteum, Spiniferites ludhamensis n. sp., S. rubinus, and Trinovantedinium glorianum. The dinoflagellate Spiniferites ludhamensis n. sp. and acritarch Nannobarbophora walldalei n. sp. are formally described.
