Warthia ? sp. 2

( Fig. 5 H–J)

Material. One specimen: ESKU-19- LP 57.

Dimensions (mm): ESKU-19-LP 57: height = 11.1; width = 11.1; thickness = 8.9.

Remarks. This smooth bellerophontoid seems to be a representative of the genus Warthia , but the poor preservation prevents a certain generic assignment. The species can be differentiated from Warthia cf. welleri by being anomphalous and by the absence of an indentation on the aperture. It differs from Warthia sp. 1 by a more inflated shape and a wider aperture.
