Nautilus singular, nautili plural are nautiloids which are a type of cephalopod. The cephalopod group include modern day octopi, squids and cuttlefish. Cephalopod named from the Greek and so aptly named, loosely translated into English as head-foot. The cephalopods including the extinct ammonoidea group ranged from the Cambrian period around 500 million years ago up to the Cretaceous period around 65 million years ago. An immense period of time which led to much dimorphism between different genera. The nautili continue to persist today in the Pacific ocean. Read about this fossil nautilus below...

A natural Nautilus, which has been treated with an acid preparation giving the fossil a more organic appearance. The chambers clearly distinguished containing solidified calcification, Calcite minerals have grown within the shell, this occurs during the fossilisation processes. The chamber alignment is a very interesting feature of this specimen. The shell chambers having warm brown tonal colours to white-green calcite inclusions, calcite of the quartz mineral family. The fossil cleaned and prepared on its natural and original host bedrock base. This was once part of the silts of the Devonian seabed. Orientated on the bedrock, the nautiloid presents a pleasing natural sculptural form as well as a scientifically interesting fossil specimen.

The natural calcification within the chambers, which can be seen now the shell has been removed offer a delightful and interesting view into the form of the nautilus fossil shell. The internal structure and how the animal existed in its prehistoric home. Sediments of time have created muted colourisation, caused by the absorption of minerals in the fossil limestone bed, this a type of fossil metamorphism, the limestone was once a silty seabed around 380 million years ago, the habitat of the cephalopods, a type of marine mollusc similar in attributes to the modern day Nautilus.
