Phorcus sp.

Figs 21U, 22A

Material. Specimen MGUH 33109, an external mould of the spire.

Occurrence. Lithified top of the Maastrichtian Tor Formation at Holtug Quarry.

Description. Protoconch smooth, weakly convex with flattened whorls. Transition to teleoconch gradual. Teleoconch with low cyrtoconoid spire and weakly convex whorls separated by distinct suture. Whorls in cross-section broadly rounded without keel; smooth. Aperture and abapical side of whorl not known.

Measurements. Specimen MGUH 33109 is 3.1 mm high.

Remarks. Phorcus sp. differs from the middle Danian Phorcus carinatus (Ravn, 1933) from Denmark by the lack of a carination on the whorls and a relatively higher teleoconch shell. It differs from the two Paleocene species of Phorcus from Greenland, presented under the names Osilinus sp. 1 and 2 by Kollmann & Peel (1983), by the higher shell and lack of spiral striation.
