6.5 Inch Ammonite Fossil Cut Polished and Mounted Mineral Specimen
About the Item
6.5 Inch Ammonite Fossil Cut Polished and Mounted Mineral Specimen Jurassic - Cretaceous Period, 200 - 145 million years old
Cutting and polishing this ammonite has revealed an interior with honey-brown to rich dark brown, calcite-filled largely intact air chambers. The fossilization process has resulted with a gem-like specimen. This example has retained much of its pearlescent outer shell, which is iridescent in places.
We hand-pick each set, looking for examples with great color and crystallization.
Ammonites were cephalopods that resembled a squid with a shell. The predatory mollusks had eyes, tentacles, and spiral shells resembling a nautilus shell. Ammonites are closely related to an octopus without the shell. They appeared in the fossil record about 240 million years ago with the last descendants disappearing from the record 65 million years ago, at the end of the Cretaceous period.
Custom mounted on metal display stands with a black painted finish.
