The listing, New Ammonite Fossil Earrings has ended.
This is new pair of ammonite fossil earrings that are 34X28X8mm and 21 grams. One picture shows the front side and the other shows the back side. The ad where I bought these from did not say what the silver is. So, if your a person that has to wear sterling silver in your ears and you win this bid, let me know and I will throw in a pair of sterling hooks to replace these with just to make sure. These aren't real heavy earrings in my opinion. I can wear them with no problem, but if your someone that can only wear light weight earrings, I would not bid on them if I were you. They are super neat conversation piece earrings.
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. Ammonites belong to a group of predators known as cephalopods, which includes their living relatives the octopus, squid, cuttlefish and nautilus. These sea creatures first appeared 415 million years ago in the form of a small, straight shelled creature, known as Bacrites. They quickly evolved into a variety of shapes and sizes including some shaped like hairpins. 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.
