What is an Orthoceras Fossil?

This necklace is made with a beautiful polished Orthoceras fossil from Morocco dating 400+ million years ago. The word Orthoceras means 'straight horn' which refers to the long, straight and conical shaped shell. Did you know that the Orthoceras is a genus of extinct cephaloid (animals related to squid, octopus and nautilus) and ranged in size from a few centimeters in length to over six feet? They could crawl as well as swim and filled the chambers in their shells with air to help them float, when they died the shells accumulated on the ocean bed, sediment covered them and over many, many years they transformed into stone.
