9.2" Cruziana (Fossil Arthropod Trackway) Plate - Morocco

This is a spaghetti-like fossil trackway (cruziana) of an arthropod, collected near Erfoud, Morocco. A variety of different trackways can be seen throughout the stone. The slab of mudstone measures 9.2" by 4.6" and would be Ordovician in age, or approximately 450 million years old.

It comes with an acrylic display stand.

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: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
