In this episode of Gem Connection we discuss ammonite, an ancient squid-like creature that lived over 400 million years ago and survived three mass extinctions. We'll relate it to my favorite ancient Greek coin minted by Lysimachus, one of the Alexander the Great's top generals, and then to the Fibonacci Sequence.
