Description
Margin circular, without notches, lappets or tentacles, ?exumbrella with prominent concentric grooves and rugae which may extend to margin, and very numerous, fine radial striae not continuous into mid-field, which may contain raised central knob; ?ring canal present. [Of the 3 species originally described by SPRIGG, C. radiata is here regarded as a synonym of Tateana inflata SPRIGG (=Ediacaria flindersi SPRIGG, p. F74). Whether the remaining 2 are also synonyms of Ediacaria is impossible to decide at present.]
