TRILOBITES: HIGHLY SUCCESSFUL ANCIENT ARTHROPODS

Trilobites are an extinct group of marine arthropods that first appeared in the Early Cambrian. They left many beautifully preserved examples of their three-lobed exoskeletons in the fossil record.

The last of their lineage went extinct at the end of the Permian, 252 million years ago.
