Small Enrolled Acastoides Trilobite Fossil - Morocco

This is a small, partially enrolled Acastoides trilobite fossil from Morocco. It's Lower-Middle Devonian in age or around 380 million years old. Trilobites enrolled for defensive purposes and are often found preserved in this posture.

Comes in an acrylic display case.

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.
