Ammonites are part of the Ammonitida of marine invertebrates. These were fascinating creatures from the deep oceans and believed to be aggressive creatures like squids today. With extremely large eyes and remarkable vision, they could easily hunt on their prey at great depths where little or no light penetrates the deep oceans. The Cephalopod would attain its prey using their long tentacles, prey such as other crustaceans and fish, much as the persisting modern-day Nautilus Pompilius which can be found in the Pacific today.

A few years ago off the Great Barrier Reef at depths between 200 to 400 meters, sightings of the Nautilus Pompilius were made, showing the pressures these Cephalopods can attain. The Ammonites extinction is dated around 74 million years, pre the great mass extinction of around 65 million years. Ammonites are important index fossils, it is often possible to link the sediment layer in which they are found to specific geological time periods. The largest ammonite to date is around 2.5 meters in diameter from Germany.
