It has not been recorded in Unit B4, and rarely in the overlying Lede Sand Formation at this locality. It occurs in many outcrops of the Brussel Sand Formation in its type-area (Vossem, Neerijse, St-Lambrechts-Woluwe, Nederokkerzeel, etc.), essentially in Unit B3 and is known from Unit B

Hence, its range in the North Sea Basin seems to be restricted to NP14 and the lower part of NP15, with a major influx in the lower middle part of NP14 (Unit B3).

The stem is slightly inflated in its upper part, reaching its maximum thickness at about 1/5 of its length, measured from the rounded distal tip. Its surface is rugose. The basal plate consists of 1 layer of radially oriented elements.
