    Cenoceras Nautiloid 103mm

    £142.00
    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.
