Two Ammonite Fossils In Rock - Boulmane, Morocco

This is two, unidentified fossil ammonites from Morocco. They are still partially imbedded in the stone in which it was found. The elaborate suture lines of the inner shell are visible under magnification on the largest ammonite. The stone contains a number of other unidentified fossils.

Ammonites were predatory cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
