1 to 2" Calymene (Colpocoryphe) Trilobite Fossils

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 1 to 2" 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.

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
