Early ammonites appeared in the lower Devonian, about 400 million years ago, and underwent immediately a rapid evolution that reached its peak during the Mesozoic. They disappeared about 65 million years ago, during the great extinction at the end of the Cretaceous. Due to their constant evolution, long-term existence and spread in all oceans of our planet, the ammonites are considered important index fossils, essential for the relative dating and correlation between rock layers from the late Paleozoic to the entire Mesozoic.
