Carry your love of fossils, cephalopods and the Fibonacci sequence with you.  This vegan leather keychain is engraved with one of the most prominent creatures from the cretaceous era: the ammonite.  Ammonites looked similar to the modern nautilus, and lived throughout the oceans covering the earth for about 140 million years.  Pay homage to this ancient creature and keep your keys coralled all at once.
