Ammonite Fossil Pendant

This unique Ammonite Fossil Pendant is over 100 million years old and looks great on everyone. It has been cut and polished to reveal the spectacular mineralization of the flotation chambers and was collected in southwestern Madagascar. It’s truly a gorgeous piece of natural history!

Ammonites have intrigued and fascinated humans for thousands of years. Many cultures — from Australian aboriginals to the ancient Egyptians - collected and treasured these prehistoric and beautiful fossils. Perhaps their lure has something to do with the Fibonacci spiral pattern of their shell, which mirrors the galaxies. Ammonites belong to the Mollusca Phylum in a Class known as Cephalopods – “head-footed” creatures such as octopus and squid. They swam in ancient oceans from 400 million years ago, to their extinction, along with the dinosaurs, 65 million years ago.

Ammonites were free floating invertebrates that were attacked by plesiosaurs and mosasaurs, two groups of gigantic marine reptiles. One way that ammonites could avoid an attack was to quickly change their buoyancy levels, zig zagging and sinking rapidly. These incredible prehistoric animals ranged in size from tiny species only a few centimetres in diameter to the monstrous Cretaceous ammonite, Parapuzosia seppenradensis, which grew to about 3 meters and would probably weigh close to 1500 kilograms!
