Orthoceras on Rock Single Fossilized Squid Cephalopod Mineral Stone Morocco

Description

Up for sale is this cephalopod fossil that was given to me as a gift from my father-in-law.  He was an avid gem and mineral collector who attended many rock and mineral shows in the northeast.  He often traded specimens he had collected with others and this is one of those that he received in trade.  I'm downsizing now and this did not make the cut.  Not sure what it's worth.  Thanks for looking.
Here is some information I "borrowed" from another seller:

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.
