In this example, the complex pattern of sutures that separated the air chambers, appear white, with honey jewel-tone and brown crystals with other fossil material. Traces of the creamy original shell are present in a few small areas, and several air chambers are visible.

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 three whole ammonites for comparison. They range in size from 7.5 - 10 inches high (19 - 25 cm). The example in this listing is on the right.
