Ammonite fossils are one of the most well known and recognized fossils in the world. They were a predatory marine mollusk that first appear in the fossil record about 240 million years ago. Even though they are more closely related to the octopus, squid, and cuttlefish, this cephalopods shell more closely resembled that of that Nautilus, which is still alive today.
