Lamarckina sp., from Todd (1965).

Belongs within: Globothalamea.
Contains: Robertinidae, Ceratobuliminidae, Epistomininae, Epistomariidae.

The Robertinida are a group of calcareous Foraminifera known from the Jurassic (possibly Triassic) to the present, in which the test wall is composed of aragonite rather than calcite (Loeblich & Tappan 1964b).

Characters (from Loeblich & Tappan 1964b): Test trochospiral, chambers divided internally by partitions; wall perforate-radial in structure, of aragonite; aperture a low slit in chamber face, with secondary aperture in each septum above partition.
