These are real Calymene trilobite fossils from the Anti-Atlas Region of Morocco. These trilobites are preserved as internal molds within the sandstone formation and are fairly common making them a very inexpensive trilobite fossil for their size. These trilobites have often been referred to as Flexicalymene ouzregui but the genus/species names are been continuously in flux. The trilobite fossils range from 2 to 3" long with most being in the middle of that size range. They aren't perfect, some will have a missing cheek or a repaired crack but are in general pretty good quality. The photos provided are representative of these fossils, but are not of the exact specimens that you will receive. An ID card will be included for each specimen.
