Damassadinium californicum, from here.

Belongs within: Peridiniphycidae.

The Cribroperidinioideae are a group of dinoflagellates known as fossil cysts from the Middle Jurassic to the Miocene (Fensome et al. 1993).

Characters (from Fensome et al. 1993): L-type ventral organisation; dextral torsion present; apical pore complex contacted by four or five plates; six Kofoid precingular plates, with sixth (1i) pentagonal and broadly geniculate anteriorly, and third precingular homologue (4) in middorsal location; six cingular plates; ends of cingulum not overhanging, sulcus straight and relatively broad throughout its length; five or sixth Kofoid postcingular plates, first (if present) and second postcingular homologues strongly reduced in size relative to third to sixth homologues.
