Cephalopods include squid, octopus, cuttlefish, nautilus, spirula, and the extinct ammonites and belemnites. Cephalopods first appear in the fossil record nearly 500 million ago during the Ordovician Period. They are all mollusks, members of the same Phylum Mollusca as oysters, conches, and the common garden snail.
TRILOBITES FIRST APPEARED AROUND 540 MILLION YEARS AGO. Their debut roughly coincided with the dawn of the Cambrian period. During this game-changing chapter in Earthâs history, multi-celled organisms went through an apparent explosion in diversity, or at least an explosion in life forms that leave fossils. New creaturesâincluding a barrage of mollusks and arthropodsâseem to have evolved at an unprecedented rate.
