In this example, the complex pattern of sutures that separated the air chambers appear white, with fossil material colored honey, brown, sage, and green between. The creamy original shell is present in a few areas of the central spiral. In the images, a partial wide band of red iridescence appears as a large honey-brown outer ring on one side of the specimen..

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 ammonoids became 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.
