Trilobites were marine arthropods, and are named for their 3-lobed, segmented bodies. They thrived in early Paleozoic oceans around the world, and eventually died out in the mass extinction that occurred at the end of the Permian Period 250 million years ago. They existed for approximately 300 million years. They are believed to be related to modern horseshoe crabs.
This collection of trilobite fossils were discovered in the Alnif region of Morocco, and are believed to be from the Devonian period.
