Abstract. Oligosphaeridium is a gonyaulacacean dinocyst lacking cingular processes and possessing a distinctive process centred on the antapical plate indicating a sexiform hyposomal tabulation. However, specimens referable to the description of Oligosphaeridium prolixispinosum Davey and Williams, 1966, although lacking cingular processes, are clearly not sexiform. As an additional complication, the holotype of Oligosphaeridium prolixispinosum possesses cingular processes. In this brief…

LITOSPHAERIDIUM TOO: TWO NEW DINOFLAGELLATE CYST SPECIES FROM THE CRETACEOUS OF CALIFORNIA
TLDR
The ‘Middle’ Cretaceous of the Northern California Coast Ranges has yielded unusually well-preserved specimens of Litosphaeridium, some of which have been analyzed in detail previously, and two species, which are from the late Albian based on the associated dinoflagellate cysts.
