Trilobites were a highly diverse group of marine arthropods, now long extinct. They first appeared in the Early Cambrian (about 521 million years ago) and thrived until the Permian mass extinction (around 250 million years ago). With over 25,000 described species, trilobites were among the most successful early animals on Earth. Their hard exoskeletons have left behind one of the richest fossil records known to science.
