Anatoma View in CoL ? sp. B

Fig. 20J View FIGURE 20

Material. Specimen MGUH 33092, representing a very fragmentary external mould. Occurrence. Lithified top of the Maastrichtian Højerup Member, Tor Formation, at Rødvig, Stevns Klint.

Description. Adapical part of spire whorl weakly convex, nearly horizontal. Base moderately convex. Sculpture on spire whorls consisting of close to 60 sigmoid transverse threads per whorl, threads continuing onto base, becoming slightly opisthocyrt to sigmoid. Transverse threads crossed by weaker, more closely spaced spiral threads.

Remarks. The fragmentary state of the specimens makes generic classification rather difficult, but it is here tentatively assigned to Anatoma . Anatoma ? sp. B resembles the contemporaneous Anatoma sp. A described above, but differs by the weakly sigmoid transverse threads and the closely spaced spiral threads.
