Ammonites are extinct members of the Cephalopod class. Modern members include nautilus, squid and octopus. They first appeared during the Silurian Period (425 million to 410 million years ago) and were abundant and widespread in the seas of the Jurassic and Cretaceous periods (175 million to 65 million years ago). Ammonites are important index fossils.... that is, they often link the rock layer in which they are found to specific geological time periods.
Ammonites varied greatly in size starting as small as 3/4" (2 cm) in diameter. During the Jurassic and Cretaceous periods, ammonites evolved more streamlined shells for swimming and the structure of the shell became stronger. Different shell shapes emerged as well, such as snail-like or uncoiled.
The shells of ammonites had hollow chambers separated by walls called septa. A tube called the siphuncle, connected the body with the chambers allowing the animal to fill them with water or air, changing its buoyancy in order to rise or drop in the ocean. Only the last and largest chamber was occupied by the living animal.
Ammonites probably lived for one to six years, with the majority living two to four years. They fed on plankton (tiny free-floating organisms), sea lilies, and smaller orthoceras. Although many fed off the ocean floor, others may have caught plankton while floating or swimming via jet propulsion, expelling water through a funnel-like opening to propel themselves in the opposite direction.
Because ammonites lived exclusively in marine environments, their presence also indicates the location of prehistoric seas.
These beautiful Ammonite Fossils were found in Madagascar in the Mahajanga Province. They are professionally cut in half and polished. With the ammonite at 2.67" (67.82mm), you can see that besides displaying them on the stands, they are also great for necklace pendants and all kinds of jewelry.
Calcite crystals form on the inside of the ammonite which is called "Ammolite". "Ammolite" is a rare and valuable opal-like organic gemstone. It is arguably the rarest gemstone on earth, rivaling the rarity of such gemstones as "Alexandrite" or "Red Diamonds". Because of the careful and detailed work to create this gorgeous design, we are able to offer this truly exceptional specimen resulting in capturing a piece of Madagascar's geological past.
Be assured that you will receive the exact same ammonites as shown in the photos above.
