Ammonoidea: History & Culture

Ammonoids are extinct, typically coiled-shelled cephalopods composing the subclass Ammonoidea. They are more closely related to living octopuses, squid, and cuttlefish (which compose the clade Coleoidea) than they are to nautiluses (family Nautilidae), which they resemble. The earliest ammonoids appeared during the Emsian stage of the Early Devonian…
