Description: Ammonite polished to show outside formation,both sides of this ammonite are polished and size 1 inch plus approximately with at least one side exhibiting the some ammolite fire.Ammonite fossils ,genus Prolyelliceras.Easily identified and great educational hands on learning tools for replacement fossils. Ammonites are the fossilized remains of squid-like animals which existed from 420 million years ago till the mass extinction at the end of the Cretaceous period, 65 million years ago. It is believed that the structure of the shell was strong enough to withstand water pressures down to 500 meters.Fantastic as a collector specimen these fossils are from Madagascar.The ammonite shell pattern is still seen today in shells of other mollusks.Ammolite is a name given to the iridescent opal-like play of color as shown in these fossil specimens from Madagascar. The effect of the light passing through the various layers of aragonite and conchiolin mineralization results in the intense reds, yellow orange green color flashes of Opal-like fire. Jewel-quality material such as this is termed Ammolite in the trade, and typically commands a high price. Ammonites are an extinct group of marine invertebrate animals and as molluscs are more closely related to living squid,cuttlefish and calamari than they are to shelled nautiloids of today.The earliest ammonites appear during the Devonian, and the last species died out during the Cretaceous extinction event.The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled ram horns ("Horns of Ammon") because the Egyptian god Ammon was typically depicted wearing ram's horns.These particular ammonites are from North Africa near the Sahara desert Ammonites are the fossilized remains of squid-like animals which existed from 420 million years ago till the mass extinction at the end of the Cretaceous period, 65 million years ago. It is believed that the structure of the shell was strong enough to withstand water pressures down to 500 meters.The ammonite shell pattern is still seen today in shells of other mollusks.
