Ammonite Nautilus Madagascar Fossil. The fossil is a nice home decoration and makes your home more beautiful and brings you archaeology to your living- or bedroom. Ammonites are an extinct group of marine cephalopods with a coiled external shell that appeared during the Devonian period and into the Cretaceous period 240-65 million years ago. This was about the same time as dinosaurs disappeared so ammonites are valuable in dating rocks. Fossils were formed when the remains of ammonites became covered in sediment, which later hardened into rock. Ammonites were predators and were related to octopus, cuttlefish and nautilus. Nautilus, which date back to the Cambrian period, have lived unchanged for millions of years.
