Cretaciclavulina gusici n. gen., n. sp. (?family Valvulinidae BERTHELIN, 1880), a new larger benthic foraminifer from the lower Campanian of Bra? Island, Croatia

摘要

The larger benthic foraminifera Cretaciclavulina gusici n. gen., n. sp. is described from the lower Campanian Pu?i??a Formation of the Island of Bra?, Croatia. With its elongate test, trochospiral to uniserial coiling, simple chambers, paraporous wall structure, and areal aperture provided with a cribrate apertural plate, Cretaciclavulina is tentatively placed into the family Valvulinidae BERTHELIN, 1880. Besides Neobalkhania bignoti CHERCHI, RADOI?I? & SCHROEDER, 1991, Fleuryana adriatica DE CASTRO, DROBNE & GU?I?, 1994, and Reticulinella fleuryi CVETKO, GU?I? & SCHROEDER, 1997, Cretaciclavulina gusici represents the fourth benthic foraminifera newly described from the Upper Cretaceous shallow-water carbonates of Bra? Island.
