N2 - A palynological study of marine Jurassic deposits of the Danish Subbasin has identified most of the zones and subzones of the dinoflagellate cyst biozonation established in the British Isles. One new subzone of the Mancodinium semitabulatum Zone, the Parvocysta nasuta Subzone (latest Early Jurassic to earliest mid-Jurassic), is proposed. The Early Jurassic zonal scheme is correlated with existing miospore and ostracod zonations. Middle Jurassic strata in Denmark are mainly non-marine. Study of Late Jurassic ammonite-dated samples from Poland has provided additional control on the correlation of the Danish dinoflagellate cyst zonal scheme. Dinoflagellate cysts in the Volgian Scythicus Zone of Poland allow reliable correlation of this zone with the Portlandian Albani Zone of England and Denmark. One new species of dinoflagellate cyst, Nannoceratopsis ridingii, is described.
