Orthoceras was an ancient mollusk that lived more than 400 million years ago. The name means straight horn, referring to the characteristic long, straight, conical shell. The preserved shell is all that remains of this ancestor of our modern-day squid. A famous and very large fossil deposit of prehistoric straight cephalopods known as ORTHOCERAS, can be found in Morocco, North Africa. Hundreds of millions of years ago, this region was covered by ocean and as they died, their shells accumulated in great numbers on the sea floor where they were aligned by currents, buried by sediments, and transformed over the ages into stone. Today, this prehistoric sea floor is now part of the dry, desolate Atlas Mountain Range in southern Morocco.
