  1. New Cenoceras Nautiloid 60mm

    Cenoceras Nautiloid 60mm

    £39.00
    Both the Ammonites and Nautili evolved from cephalopod beginnings in the Cambrian period. The Ammonoid group eventually dominating the prehistoric marine environment, being free swimmers above the seabed, before the arrival of vertebrate fishes to the marine scene. Nautiloids having early success were later in the Cretaceous period seemingly in decline. The mass Cretaceous extinction, the KT boundary event, which is the marker for the extinction of dinosaurs and many other life forms gave the tenacious Nautili a chance to regain a secure foothold under the oceans.

    An Internal Oncocerida per-mineralised calcite (quartz), fossilised exoskeleton, once the aragonite shell produced by the mollusc (cephalopod). The fossil chambers of the nautiloid shell clearly distinguishable, the last being the largest chamber where the soft body of the cephalopod resided from where it would grow the next larger additional living chamber. The nautiloid an extinct marine cephalopod, its head and many smooth tentacles would have possibly been protected when in danger by a cover made of calcite (unlike the rest of the shell of aragonite), a hinged lid over the shell aperture. The white mineralised chambers were added in the cephalopods life as it grew, each chamber progressively larger than the preceding chamber. Read more below...

    Fossil Nautilus 149mm

    Fossil Nautilus

    Regular Price: £137.00

    Special Price £98.00

    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...
