These specimens were found in Mahajanga, Madagascar, and date back to the early Cretaceous period (roughly 100 million years ago). These Ammonite fossils have been cut into pairs and polished, with natural backs. The colors range from a blonde yellow to a deep reddish brown - the picture shows an example of the range of colors the pairs display. If you have a preference on the color you receive, please describe in your order notes.
Each half approx. 1" x 1.5"
Ammonites are prehistoric nautilus related to the modern day nautilus, squid, and octopus family. These squid-like creatures lived in the sea between 65 - 415 millions years ago. Ammonites are called cephalopods because their heads and tentacles protruded out of the same opening; they grew by building larger chambers on their shells. Some species have been found at almost 6 feet in diameter, but they may have reached up to 9 feet!
