1.15" Ordovician Trilobite (Euloma) - Zagora, Morocco
This is a orange, 1.15" long Euloma trilobite from the Lower Ordovician deposits near Zagora, Morocco. The coloration is natural and due to the oxidization of iron pyrite. 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 with over 25k described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left a excellent fossil record.
