Restudy of some larger dinoflagellate cysts and an acritarch from the upper Cretaceous of Belgium and Germany

An account is presented of a restudy of type material of 13 species of dinoflagellate cysts and one species of acritarch from Upper Cretaceous flints of Belgium and Germany. The new combinations Amphorosphaeridium major (Lejeune-Carpentier), Hystrichokolpoma? crassipes (Reade) and Deflandrea damasii (Lejeune-Carpentier) are proposed. The former Exochosphaeridium spinosum var. deflandrei is elevated to specific status, as Fibrocysta? deflandrei (Lejeune-Carpentier). The former Hystrichosphaeridium cruciatum is shown to be an acritarch ; the new combination Veryhachium? cruciatum (0. Wetzel) is... Mehr ...
