Ammonites were marine animals belonging to the phylum Mollusca and the class Cephalopoda. They had a coiled external shell similar to that of the modern nautilus.
The ammonites became extinct at the end of the Cretaceous, at roughly the same time as the dinosaurs disappeared.
*Specimens will vary in colour, pattern and some are solid (don't have the empty chambers where crystals form).
