Ordovician (circa 430 million years old), Morocco
Beautiful polished fossil stone with Orthoceras
The Orthoceras is an extinct genus of molluscs, that lived during the mid-Ordovician.
This nautiloid cephalopod had a tapered, cylindrical, cone-shaped shell with chambers situated close together, containing a hollow and spherical septum, with at the centre a connecting tube, the sipho. The length of the shell was approximately 15 cm. The orthoceras was a mollusk, so the only thing that was petrified is the squid’s ‘vertibra’.
In excellent condition.
