Two Trilobite Cruzianas (Fossil Trackways) - Morocco

This is a fossil trackway (Cruisina) plate of an arthropod, likely a trilobite, from near Erfoud, Morocco. This Cruziana has two trackways preserved in a slab of mudstone and would be Ordovician in age or approximately 450 million years old. The longest trackway is 4.7".

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 with over 25k currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
