Gypidula sp.

Fig. 6F .

Material.—Seven small fragments of disarticulated valves from Wietrznia Id−W (beds 4 and 14) and Ie (beds 29–30, 44–45, and 65) sections.

Remarks.—The described specimens can be attributed to the genus Gypidula on a basis of its very strongly convex ventral valve with a very massive umbo and characteristic short and thick radial plications which occur frequently in several species of the genus. Similar gypidulid was described by Godefroid and Racki (1990) as Metabolipa cf. greindli ( Maillieux, 1909) from approximately the same age deposits of nearby Bolechowice, Kadzielnia and Szczukowskie Górki.

Occurrence.—Very rare species in Wietrznia Id−W and Wietrznia Ie.
