Orthoceras
Orthoceras was an ancient cephalopod that lived about 370 million years ago during the Devonian period.
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 and these ones are preserved in black marble with unpolished specimens showing through the base.
