Description: Rhabdolith with a vase-shaped spine constructed from two distinct structural units when viewed in XPL. The short lower-spine unit broadens away from the coccolith and the longer, upper-spine cycle tapers to a point. The rim is dominated by the inner of the two cycles; the outer cycle does not lie distally over the inner cycle. Typically the height is around twice the width, and the maximum spine width is similar to that of the coccolith.

Remarks: The two-part spine structure is similar to that seen in Blackites deflandrei and Blackites pseudomoronium, but the lower-spine unit is smaller and the upper cycle longer.
