Belongs within: Fusulinida.

The Palaeotextulariidae are a group of primarily biserial Foraminifera known from the Carboniferous and Permian. In some genera (Palaeotextularia and Deckerellina) the test remained biserial throughout, but in others (Climacammina, Cribrogenerina and Palaeobigenerina) it became uniserial in later stages of development (Loeblich & Tappan 1964).

Characters (from Loeblich & Tappan 1964): Test biserial or may become uniserial; wall granular calcareous, with inner layer and thin adventitious coating; aperture simple or multiple.
