---------------------------------------------------------------------------------------------------

Locus typicus: Papuan Basin, Papua New Guinea
Stratum typicum: Oxfordian-early Kimmeridgian

Original diagnosis: Davey, 1988, p.43: Productodinium
Shape: The body is elongate to ovoidal.
Wall: Apparently two layered with the outer layer developed into various low features such as granules, tubercles, bacules and low spines.
Paratabulation: A poorly defined cingulum may be present. Some of the wall features may be aligned along the axis of the cyst and are probably sutural.
Archaeopyle: An apical archaeopyle is developed by the detachment of the apical plates as a unit (Type tA). The archaeopyle has a strongly zigzag margin.
Size: Moderate.
