Orthoceras Fossils: Ancient Cephalopods

These are 400 million year old polished Orthoceras (cephalopod) fossils from the Atlas Mountains of Morocco. They range from 2 – 3″ in length, with most being in the middle of the range. The photos are representative of the ones you will receive but not the exact ones. Quantity discounts are available.

What Are Orthoceras?

The fossils commonly known as Orthoceras are extinct “straight” cephalopods that lived during the Upper Devonian period around 370 million years ago. Like other cephalopods, they lived inside of their shells, had tentacles they could use 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 reveal the fossils and make decorative items with them.
