This authentic trilobite fossil is approximately 1.7 inches long. This was found in Morroco.
Trilobites meaning “three lobes” are a group of extinct marine arthropods, which were invertebrate animals with an exoskeleton. For the animal to grow, the exoskeleton had to be shed and the shed trilobite exoskeletons are often what became fossils. They lived during the Cambrian to Permian periods (542 to 251 million years ago).
