Morphology

ammonitic = ammonite (transparent) = ammonite + ic

Clearly formed from the noun 'ammonite' plus the adjectival suffix '-ic', meaning 'relating to ammonites'.

Etymology

Ammonitic comes from ammonite, the spiral fossil named after the Egyptian god Amun, also called Ammon, because the shell looks like his curled 'horns'. So ammonitic means 'relating to ammonites' or to their shell patterns.
