 Ammonites inhabited our oceans for 440 million years, from the Devonian period to the late Cretaceous (66 million years ago). They are cephalopod mollusks, with highly varied and abundant fossil shells. Cephalopod animals are characterized by having tentacles on their heads—hence their scientific name, which literally means "head with feet"—like modern octopuses or squids.
