Small Pastel Fire Opalized Ammonite (M7994)SOLD!Ammonite is a fossil of an extinct sea predator that lived over 65 million years ago. They belonged to a group known as cephalopods which are known today as squids, octopus, cuttlefish and nautilus. The ammonite shell is made of the mineral aragonite, a form of calcium carbonate and is divided into a series of air chambers. The series of air chambers allowed for ammonite to float. This beautiful ammonite is from Tullear, Madagascar, one of the better known reefs of the world. These ammonites are a special find from Tucson because they have not been polished. They are completely natural, yet they are still quite shiny, a very rare find.
The fossil measures 1.45" x 1.3" x 0.6" and weighs 0.8 oz. |
