9" Ordovician Trilobite Mortality Plate - Tafraoute, Morocco
This is a mortality plate of over thirty, Ordovician trilobites from Tafraoute, Morocco. The entire piece of limestone is 9x8.1" with most of the trilobites being about 1 1/4" in length.
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.
