Calcified aptychi only occur in ammonites from the Mesozoic era. They are almost always found detached from the shell, and are only very rarely preserved in place.

Where are ammonites found in the world?

Such outcrops include quarries, sea coasts, river shores, deserts, canyons and even underground cellars.
