Ammonites are the ancient equivalent to the modern-day chambered Nautilus. These sea faring squids built a chambered shell in which they would pump air into the empty chambers and float at different levels of the ocean in search of food. This unique ability to float at different depths of the ocean is what inspired Jules Vern (the famous science fiction writer) to call the first submarine the Nautilus. Ammonites lived approximately 400 million years ago Moroccan Fossil Ammonite from the Devonian Period - 400+ millions years old. The extinct ammonite that decended from Nautiloids is an example of the remarkable symmetry often found in nature. Ammonites were Cephalopods sharing a common ancestor with the squid and octopus that appeared in the Devonian and disappeared with the dinosaurs at the end of the Cretaceous period.
