Trilobites are a group of extinct marine arthropods that 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). Trilobites were among the most successful early animals, with over 25,000 species having been described to date.
The photos provided are representative of these fossils, but are not of the exact specimens that you will receive. While these are of overall good quality, some may have imperfections (e.g., a repaired crack).
