Anatifopsis minuta Chauvel 1941
Ordovician (Llandeilian)
Col de Tanekfoult, North of Zagora, Morocco

Rare 12mm carpoid with partial second on 54mm slab.

Anatifopsis is a genus of carpoid known from the Ordovician of north Africa and Europe.

Carpoids appeared during the Cambrian and may have survived into the Carboniferous. Scientists have been fascinated by the group once considered stem-group echinoderms and then allied with other groups because they lacked the radial symmetry of echinoderms. In fact, they lack any symmetry and can be variable in form. However, because their skeletons have the same calcite-composed, crystalline structure as echinoderms, they are classified as such.

This specimen comes from a time relatively early in their history.
