Patella sp.

Plate 1: fig. 1

Material.

1 specimen, SNSB – BSPG 2016 XXI 1601 (collection O. Neubauer).

Description.

Shell 7 mm long, with broadly oval outline and rounded edges in dorsal view; shell lowly limpet – shaped; apex in almost central position; central portion of shell lacks visible ornament (due to preservation?); shell otherwise with numerous strong, somewhat bulging radial ribs with 1 or 2 weaker radial ribs in between (details unclear); in addition shell ornamented with numerous weak concentric ribs.

Remarks.

Patella staceata Gründel, Hostettler and Menkveld-Gfeller, 2020 is very similar but differs in having numerous weaker radial ribs between the strong main radial ribs. The single, probably juvenile specimen is too poorly preserved for a better identification.
