Trochammina inflata, copyright Dr. Fabrizio Frontalini and Prof. Rodolfo Coccioni.

Belongs within: Globothalamea.

The Trochamminidae are a group of trochospiral agglutinating foraminifera known from the Carboniferous to the present. In the Recent genus Remaneica, the chambers are internally subdivided by infoldings of the wall; the remaining genera (forming the subfamily Trochammininae) have the interior simple (Loeblich & Tappan 1964).

Characters (from Loeblich & Tappan 1964): Test free or attached, trochospiral; wall agglutinated; aperture interiomarginal or areal, single or multiple.
