Ammonites are cephalopods and first appeared in the seas 415 million years ago, in the form of a straight shelled creature known as Bacrites. During their evolution three catastrophic events occurred. The first during the Permian period (250million years ago), only 10% survived. They went on to flourish throughout the Triassic period, but at the end of this period (206 million years ago) all but one species died. Then they began to thrive from the Jurassic period until the end of the Cretaceous period when all species of ammonites became extinct.
Ammonites began life very tiny, less then 1mm in diameter, and were vulnerable to attack from predators. They fed on plankton and quickly assumed a strong protective outer shell. They also grew quickly with the females growing up to 400% larger then the males; because they needed the larger shell for egg production. Most ammonites only lived for two years. Some lived longer becoming very large. The largest ever found was in Germany (6.5 feet in diameter).
