Dietze V., Schweigert G., Fidder U., Wannenmacher N. (2011) The Giganteuston Member of Öschingen (Humphriesianum Zone, Lower Bajocian, Swabian Alb), with comments on the genera Dorsetensia Buckman, 1892 and Nannina Buckman, 1927 // Zitteliana A 51, P.209–236

A section in the Lower Bajocian Giganteuston Member is described from Öschingen (Middle Swabian Alb). The examined part of this member yielded a sonniniid fauna of the romani horizon (Humphriesianum Zone, Romani Subzone), followed by a stephanoceratid fauna in the mutabile horizon (Humphriesianum Subzone). Öschingen is the type locality of Dorsetensia romani (Oppel) and Nannina deltafalcata (Quenstedt); in addition D. complanata Buckman and D. liostraca Buckman are reported from there. To clarify the taxonomic affiliation of these sonniniids, chorotypes of D. edouardiana (d’Orbigny) (= type species of Dorsetensia Buckman, 1892), D. lennieri Brasil and D. tessoniana (d’Orbigny) were studied; as well as topotypes of D. pulchra Buckman, D. liostraca Buckman, D. complanata Buckman, and D. regrediens (Haug).
