Leucorhynchia sp.

Figs 22 J–K

Material. Specimen MGUH 33115 is an incomplete external mould.

Occurrence. Lithified top of the Højerup Member of the Maastrichtian Tor Formation at Holtug Quarry, Stevns Klint.

Description. Shell very low trochiform with flattened spire. Nearly planispiral protoconch 0.55 mm wide, consisting of approximately two smooth and only slowly widening flat whorls; whorls separated by deep sutures. Transition to teleoconch not visible.

Teleoconch with around two fairly rapidly widening, adapically flattened whorls. Deep suture situated just above sharply rounded periphery of preceding whorl. Base weakly convex. Aperture and umbilical area unknown. Teleoconch sculpture consisting of a single distinct adapical furrow.

Measurements. Specimen MGUH 33115 is 1.6 mm high and at least 2.4 mm wide, consisting of 3 3/4 whorls.

Remarks. This taxon differs from the middle Danian Leucorhynchia marginata Ravn, 1933 from Denmark by a slightly higher shell and lower protoconch, but seems otherwise quite similar.
