Stereochlamis caliculum

Schrammen 1912

Stereochlamis caliculum has not been previously reported from Misburg, but from similar, Lower Campanian marl beds near Oberg. The specimen shown here consists of a small funnel that matches the description given by Schrammen (1912). However, its wall is only about 2 mm thick, while Schrammen's specimens are about twice that thick.

The skeleton is made up of small fused hexactines, forming more or less irregular, square meshes. The walls are without any particular pores.
