Medieval Europe - Ammonites were thought to be petrified snakes. They were called "snakestones" or "serpent stones". Ammonites were said to be evidence for the actions of St. Hilda and St. Patrick - who drove the snakes out of Ireland. In ancient times, traders would carve the face of a snake into the wide end of the ammonite fossil and sell them to the public.
The name Ammonite - comes from their spiral shape. The fossilized shells somewhat resembled tightly coiled rams' horns. Pliny the Elder (79 A.D. near Pompeii) called these fossils - ammonis cornua ("horns of Ammon") . Because the Egyptian god Amman was typically depicted wearing ram's horns.
