Matched Pair of Split Ammonite Fossil
This specimen is unusual as it had larger chambers than most other examples. Possibly a less common species? We hand pick each set, looking for minimal grey-matrix filled chambers. The more chambers that are filled with crystals, to our minds, the better quality the fossil.
Dating from the Jurassic to the Cretaceous period, ammonites were cephalopods that resembled a squid with a shell. The predatory mollusks had eyes, tentacles, and spiral shells similar to a nautilus shell. Without the shell, ammonites are closely related to an octopus 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.
