Go back far enough in time and the commonest predatory animals in the sea were the ammonites.
Along with their relatives the nautiloids they could be found throughout the world’s oceans and seas.
Although ammonites are now extinct, still surviving today are nautilus and their distant cousins the squid, octopus and cuttlefish.
On the Isle of Wight around 115 million years ago large forms lived, scavenging for dead remains on the sandy sea-floor and capturing slow moving fish and other ammonites in their tentacles before rending them apart with their large parrot-like beaks.
Ammonitoceras is one of the larger ammonites to be found on the Isle of Wight, and now it is an extremely heavy fossil. Certain layers are rich in these fossils, it has been suggested these areas may once have been breeding grounds.
