Homalopoma sp.

Figs 22 O–P

Material. Specimen MGUH 33117 is a very fragmentary external and internal mould of the final 2 ½ whorls.

Occurrence. The lower Danian Cerithium Limestone Member at Skeldervig, Stevns Klint.

Description. Teleoconch fairly low conical; whorls highly convex, nearly round in cross-section, separated by shallow suture. Aperture round.

Teleoconch sculpture consisting of numerous weak and fine spiral bands, more or less equally developed on spire whorls as on base. A beaded spiral band numbering perhaps 50 weak beads on last whorl runs adjacent to adapical suture. Weaker beading may be seen on several more adapical spiral bands.

Measurements. Tube diameter of last whorl 6.3 mm. Whorl radius reaches at least 6.4 mm.

Remarks. The Danish taxon resembles somewhat the Palaeocene Homalopoma sp. 1 of Kollmann & Peel (1983: p. 30–31) from Greenland, but differs by the weak subsutural constriction of the whorls and the weakly beaded adapical spiral bands. It differs from the Campanian Homalopoma minimum (Quintero & Revilla, 1966) from Spain by the finer spiral bands.
