Pleurostomellidae

Pleurostomella subnodosa, copyright AMNH, Invertebrate Paleobiology.


Belongs within: Rotaliida.

The Pleurostomellidae are a group of Foraminifera known from the Lower Cretaceous (possibly Jurassic) to the present, characterised by the presence of an internal siphon running between the apertures of successive chambers (Loeblich & Tappan 1964).

Characters (from Loeblich & Tappan 1964): Early stage triserial or biserial, later uniserial, or uniserial throughout; aperture a curved narrow slit, lateral or terminal, with internal siphon between those of adjacent chambers.
