Anarcestaceae

The Anarcestaceae is a superfamily of Devonian ammonoid cephalopods named by Steinmann in 1890, included in the Anarcestina. Shells are small to large in size, usually with a moderate to deep dorsal impression and an umbilicus that varies from wide to closed. Sutures have a small V-shape ventral lobe and rounded lateral lobes.

The Anarcestaceae, renaimed Anarcestoidea in more recent classifications, includes the Anarcestidae, Cabrieroceratidae, Sobolewiidae, and Werneroceratidae which have been found in Algeria, Canada, China,  the Czech Republic, Kazakhstan, Morocco, the Russian Federation, Spain, the United States, and Uzbekistan
