Phelodinium cranwelliae Hannah et al., 1998, p.537, figs.6c–f.
Holotype: Hannah et al., 1998, figs.6c–d.
Age: early Miocene.

Original description (Hannah et al., 1998)
Name: for Lucy CranwelI. pioneer Antarctic palynologist.
Holotype: slide P15/2, 141.8 mbsf. England diner coordinates; U45/4, figure 6d. Length = 112 µm. width = 76 µm.
Shape: large. elongate peridinioid cyst moderately compressed dorso-ventraly. Two prominent, short antapical horns. about equal in size and sharp, often filled. Apical horn can be extremely elongate with a blunt termination. usually folded. Walls semi-rigid and usually straight, except between the two antapical horns where it is concave. Specimens are often folded around the probable paracingular area.
Phragma: cornucavate. the two walls are closely appressed elsewhere on the cyst. Brown in colour. One. or occasionally two. small pores are often present near the tip of the apical horn. Ornamentation absent. No paratabulation has been noted. however. a region of strong folding often marks the position of the paracingulum.
Archaeopyle: intercalary, operculum remaining attached along the edge nearest the paracingulum.
Size: determining the length of this species accurately is difficult as many specimens have a folded apical horn
resulting in measurements that are too short. Length = 83(96)112 µm. Width = 59(71)78 µm based on nine specimens.
Distribution: common between 83.36 and 147.68 mbsf, lower Miocene.
