About the Item
Large 8 inch Split Ammonite Mounted Fossil Set
Jurassic - Cretaceous Period, 200 - 145 million years old
The cutting and polishing of this large pair revealed pale yellow-brown, calcite-filled intact air chambers—almost all the chambers in this specimen crystallized during the fossilization process, creating a gem-like, very good quality 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 a minimum of grey matrix material—the less grey matrix, the better the quality.
Mounted on custom metal stands with a black painted finish.
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.
The last photo shows three sets of ammonite pairs for relative scale. This example is the largest in the group.
