Ammonites are actually a subclass of Phylum Cephlapoda. Like modern
Cephalopods, including the Chambered Nautilus and the Squid, Ammonites
had well developed eyes and tentacles for grasping food. The lines on the
shell are called “suture patterns” and became increasingly complex as the
animal evolved. The iridescent on the exterior shell is a form of opal that has
replaced the nacre shell. Ammonites apparently evolved from the Ordovician
Nautiloids, but didn’t become well established until the Mid-Devonian times,
or about 300 million years ago. They are now extinct. The word
AMMONITE means “Ammon Stone” and refers to the Egyptian God Ammon, who often
appeared with ram’s horns. The mathematical pattern within the shells are
undeniable on Earth; the Golden Mean applies deeply.
