The listing, WHOLE AMMONITE PENDANT, MUST SEE COLORING 18K WGP has ended.
These pictures are all of the same ammonite, same lighting, different background. Until I took the pictures I had not realized how different the background can make. The ammonite is the darker color. But the red undertones are not from different lighting...it is the natural look.
I love fossils...and I really do like ammonite fossils. So I have had a few auctions with them. Ammonites are perhaps the most widely known fossil, possessing the typically ribbed spiral-form shell . These creatures lived in the seas between 240 - 65 million years ago, when they became extinct along with the dinosaurs. The name 'ammonite' (usually lower-case) originates from the Greek Ram-horned god called Ammon.
These sea creatures first appeared 415 million years ago in the form of a small, straight shelled creature, known as Bacrites. During their evolution the ammonites faced no less than three catastrophic events that would eventually lead to their extinction. The first event occurred during the Permian (250 million years ago), where only 10% survived. These surviving species went on to flourish throughout the Triassic, however at the end of this period (206 million years ago) they faced near extinction, when all but one species survived. This event marked the end of the Triassic and the beginning of the Jurassic, during which time the number of ammonite species grew once more. The final catastrophe occurred at the end of the Cretaceous period when all species were annihilated and the ammonites became extinct. This event apparently coincided with the death of the dinosaurs.
Ammonites moved by jet propulsion, expelling water through a funnel-like opening to propel themselves in the opposite direction. They typically lived for two years, which is estimated by looking at their living relatives - the nautilus. These creatures exist within modern day seas and possess many characteristics similar to ammonites.
