ORTHOCERAS FOSSILS FOR SALE

These fossils, commonly known by the genus name Orthoceras, are extinct "straight-shelled" cephalopods that lived during the Upper Devonian period, around 370 million years ago. They lived inside of their shells, used tentacles to grab food, and used jet propulsion, squirting water to move. 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.
