The fossils commonly known as Orthoceras are extinct "straight-shelled" cephalopods that lived during the Upper Devonian period around 370 million years ago. They lived inside of their shell, which was soft squid-like body inside a cone shell. These super fast fossils used tentacles to grab food and used jet propulsion, squirting water to move. Over time, its aragonite shell turned into calcite and Fossilised.

The rock containing them is quarried from the Atlas Mountains of Morocco and frequently polished to make decorative items with the fossils visible on the polished surface.

Each sculpture is unique height 18cm.
