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".
About Trilobites
Trilobites are an extinct class of marine arthropods that thrived for nearly 270 million years, from the early Cambrian to the end of the Permian period (around 521 to 252 million years ago). They are one of the most successful and diverse groups in the history of life, with over 25,000 described species spanning a wide range of sizes, shapes, and ecological niches. Known for their distinctive, segmented exoskeletons, trilobites provide invaluable insights into the evolutionary history of arthropods and the dynamics of ancient marine ecosystems.
