Abstract

A microproblematicum with calcaerous test, Tabasosphaera pustulosa nov. gen., nov. sp., a hollow spherical microfossil with pustule-like elements on the outer surface, is described from Upper Triassic (Norian-Rhaetian) reef limestones exposed near the town of Ali-Abad, south of Tabas (northeast Iran). Tabasosphaera is an endobiotic organism living within the cavities of other organisms, such as brachiopods, worm tubes, or in sponge spongocoels. The systematic position of Tabasosphaera, its interspecific association and the fossil assemblage of which it makes part is discussed. Most probably Tabasosphaera represents a foraminifer belonging to the group Lagenina.
