Ammonites from the Dorset Coat Digital Archive 

Ammonites were one of the most successful groups of invertebrates, with many different species found across the world, from species which could be held in the palm of your hand to giants over 1 metre in diameter. Closely related to the octopus, squid and cuttlefish, their closest living relative is the elusive Nautilus which has a chambered shall similar to the ammonites.
