Diagnoza

Only a few specimens have been found in Ostrówka . Along with very characteristic platform sp elements there are some other elements of the apparatus that may belong to the same species. They are of rather robust external appearance and share relatively deep and wide basal cavities.

The type population of the species comes from the Pierson Limestone, Roaring River Park, Barry County in Missouri (holotype Branson & Mehl l94l: pl. 19: 31, 32). According to Chauff (1985), the species originated from D. dubius Branson & Mehl, 1941, which occurs in strata older than the S. anchoralis Zone.
