Torynelasma ? sp.
Pl. 20, Figs. 11–13
Material. 11 broken ventral valves from sample JH-64. The figured specimens are TSGF 17030–17032.
Description. Ventral valve low conical and rather thick-walled. Pseudointerarea well-defined, straight, apsacline tending toward catacline, nearly as wide as valve. Outline subangular to semicircular. Ornamentation consisting of growth lines.
Remarks. The material is too poor for any closer identification of this species. The very sharply defined flat posterior margin most closely resembles Torynelasma . However, Torynelasma was not previously known from deposits of early Floian age.
Occurrence. Lower part of Nordporten Member, Kirtonryggen Formation, Basissletta in northeastern Ny Friesland, Spitsbergen.
