Fig. 3C.
Type species: Eucycloidea erratica Gründel, 1990 , original designation; glacial erratic boulder from Bauer−Wehrland / Mecklenburg−Vorpommern, NE Germany, Callovian .
Included species: Eucycloidea erratica Gründel, 1990 , Callovian; Erratothilda dziki Kaim, 2004 , Valanginian; Erratothilda krawczynski Kaim, 2004 , Valanginian;? Erratothilda wascherae Gründel, 2006 , Late Bathonian.
Emended diagnosis.—Shell and ornament basically as in Angulathilda . However, Erratothilda has three or more primary spiral ribs. Erratothilda has a pronounced micro−ornament.
Remarks.—The characteristic micro−ornament has not been shown for Erratothilda wascherae Gründel, 2006 which comes from a locality at which the preservation is not sufficient to show such fine details.
Stratigraphic and geographic range.—Questionable Bathonian, certainly from the Callovian to Early Cretaceous; Germany,? France.
