These trilobites are common fossils from Morocco. Preserved with rusty-colored limonite crystals, these are actually the molds of the shells of Flexicalymene trilobites, and are often found in nodules, loose rocky concretions which reveal their fossil contents when broken open.
Trilobites are a type of extinct arthropod probably most closely related to modern Horseshoe crabs. With a growing number of predators and adapted to diverse habitats, various species of trilobites developed complex eyes, retractable antennae, and even protective spines. Trilobites range in size from a fraction of an inch to over two feet in length. Their exoskeletons were composed of extremely hard calcite and calcium phosphate minerals to protect the soft internal organs, and as a result they are quite well represented in the fossil record.
