Costidiscus
On course for extinction
Ammonites sometimes look very similar to each other thanks to their history spanning over 300 million years. They have a planispiral shell more or less marked with ridges and tubercles. Yet they can be classified also on the basis of inner characters, so that there is never a perfect repetition. As a result, this ammonite from the Cretaceous period may always be distinguished from its ancestors.
