Apoderoceras
Genus of molluscs (fossil)
Apoderoceras is an extinct genus of cephalopod belonging to the ammonite subclass.
Ammonites (Apoderoceras) were predatory mollusks that resembled a squid with a shell. These cephalopods had eyes, tentacles, and spiral shells. They are more closely related to a living octopus, though the shells resemble that of a nautilus. True ammonites appeared in the fossil record about 240 million years ago. The last lineages disappeared 65 million years ago at the end of the Cretaceous.[3]
