Ordovician Trilobite Association (Asaphellus, Lonchodomas & Euloma)

This is a really cool association of three different types of Lower Ordovician trilobites from the Fezouata Shale in Morocco . They all have a natural, bright orange coloration due to the oxidization of iron pyrite. There is a 1.4" Asaphellus, a 1.2" long Euloma and a 2" long Lonchodomas all on the same piece of shale.

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.
