13.2" Cluster Of Large, Black Shelled Calymene Trilobites - Morocco

This is a 13.2" wide cluster of large, black-shelled Flexicalymene triobites from Morocco. Most of the calymene trilobites you see from Morocco are preserved as internal molds and don't have any shell. These ones are in hard limestone, and have a thick, black shell. All the trilobites are laid out prone, five dorsal and one ventral with the largest being 3.55" long. One specimen has restoration along it's axis and on the center of it's head, and there is some minor restoration along repaired cracks on others.
