4.9" Devonian Ammonite (Anetoceras) With Trilobite Heads
This is a 4.9" 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. There are a pair of phacopid trilobites heads naturally associated with it.
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.
