5.9" Trilobite Sandwich Mortality Plate (Three Pieces) - Morocco

Trilobite Sandwich Mortality Plate (Three Pieces) - Morocco #194115

This is a 5.9 x 4.1" mortality plate of Ordovician trilobites from Tafraoute, Morocco. There are three pieces to the plate where the rock was split twice and there are trilobites on all sides. Basically a trilobite sandwich.

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.
