Orthoceras fossil

Orthoceras fossil carved in sympathy with it’s original shape, on 66cm leathercord.

Orthoceras fossil pendants are derived from 400 million year old fossil marble.

The name Orthoceras, means “straight horn” which refers to it’s characteristically long straight conical shell is a genus of extinct nautiloid cephalopod. These ancient orthoceras fossils, ancestors of the squid, ranged in size from less than a centimeter to more than a metre. The shape and segments of the shell that housed the soft body of the organism which resided in the shell opening segment, are a result of the creature constantly outgrowing its shell, resulting in a new shell segment larger than the one before. The shell is all that remains in the fossil record, and the distinctive segments with their divisions called septa can clearly be seen in the fossil markings.
