5.5" Devonian Ammonite (Anetoceras) - Morocco
This is a 5.5" wide specimen of the Early Devonian ammonite Anetoceras, quarried in the Anti-Atlas Region of Morocco. The ammonite has been painstakingly prepared from the hard limestone matrix that it was found.
Ammonites were predatory mollusks that resembled a squid with a shell. These cephalopods had eyes, tentacles, and spiral shells. They are more closely related to a living octopus, though the shells resemble that of a nautilus. True ammonites appeared in the fossil record about 240 million years ago. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
