.63" Salterolithus Trilobite Fossil - United Kingdom

This is a Salterolithus caractaci trilobite that was collected from the Ordovician age Caradoc Series of the United Kingdom. The head of the trilobite runs off of the edge of the rock and two other heads can be found within the rock. 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.
