Abstract

Dinoflagellate cysts from the classic mid-Pliocene Coralline Crag locality of Rockhall Wood, Suffolk are described, representing the first systematic treatment of mid-Pliocene dinoflagellates from the North Sea region. The dinoflagellates broadly reflect warm-temperate surface waters whose temperatures were considerably higher than today. Two assemblages are recognized: an older assemblage (late early Pliocene or earliest late Pliocene, possibly not younger than 3.3 Ma) confined to the Ramsholt Member, and a younger assemblage (predating 2.6 Ma) confined to the overlying Sudbourne Member. Assemblages are characterized by quantitative differences and their succession indicates either: 1) slight cooling within a probable warm-temperate range; 2) a slight increase in open marine influence; or 3) a taphonomic effect perhaps related to a change in bottom currents.

Specimens have been observed using light (LM) and scanning electron (SEM) microscopy, and cyst wall ultrastructure is emphasized as a valuable but underutilized character for Neogene dinoflagellate taxonomy. Operculodinium? eirikianum Head et al. is emended and the following new taxa are proposed: Achomosphaera andalousiensis suttonensis new subspecies, Ataxiodinium zevenboomii new species, Bitectatodinium raedwaldii new species, and Operculodinium tegillatum new species. Geonettia? sp. is new to science but formal description awaits detailed analysis of tabulation.
