A richly colored example with a few open crystalized chambers on one side. There are remnants of the original shell in the spiral center.

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 octopus, squid, cuttlefish, and modern nautilus. The nautiloid both preceded and survived after the ammonoid went extinct. Ammonites 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 four whole ammonites for comparison. They range in size from 5.5 - 9.25 inches tall (14 - 23.5 cm). The example in this listing is third from left.
