Opposite sides and top view of Sigmomorphina spatula, from Loeblich & Tappan (1964b).

Belongs within: Polymorphinida.
Contains: Guttulina.

The Polymorphinidae are a group of multichambered forams known from the Triassic to the present (Loeblich & Tappan 1964b).

Characters (from Loeblich & Tappan 1964b): Test multilocular, chambers in spiral or sigmoidal coil about longitudinal axis of growth, or biserial or uniserial, typically somewhat overlapping; aberrant forms may be irregular and attached; apertures all develop in same direction, terminal, radiate.
