Allogromia laticollaris, from here.

Belongs within: Foraminifera.

The Allogromiidae are a group of Foraminifera with a pseudochitinous test known from the Upper Cambrian to the present (Loeblich & Tappan 1964).

Characters (from Loeblich & Tappan 1964): Test pseudochitinous or with agglutinated matter on pseudochitinous base; certain forms known to show alternation of generations with amoeboid gametes.
