Geinitzinacea

The Geintizinacea comprises a superfamily of Upper Devonian to Upper Permian uniserial fusulinids (microgranular foraminifera with chambers aligned in a single row), the chamber walls consisting of a dark microgranular inner layer and radially fibrous outer layer. Advanced forms show secondary lateral thickening
