Distinguishing features: Biscutum-like coccoliths with large, hollow, flaring spines, closed distally by a domed covering.


Morphology remarks: Covington (1994) noted an association of B. candens with simlar coccoliths with minimal spines, which he described as Biscutum dekaenelii - he suggests these may be  dimorphic forms on a single coccosphere.

See also: Biscutum dekaenelii - form with low spine that occurs with B. candens and may have occurred on the same coccosphere (Covington 1994);

Geological Range:
Last occurrence (top): within Maastrichtian Stage (66.04-72.05Ma, top in Maastrichtian stage). Data source: Burnett 1998
First occurrence (base): within Coniacian Stage (86.26-89.77Ma, base in Coniacian stage). Data source: Burnett 1998
