Trilobite Fossil. This trilobite fossil represents the earliest arthropods. Trilobites first appeared more than 500 million years ago. They lived for at least 200 million years before going extinct.

Some trilobites had long spines on the first leg segment. These types may have been able to tear up larger pieces of food, and probably scavenged for a living. Fossil burrows and tracks have been found that match trilobite bodies very precisely; these show that trilobites could burrow into sediment to feed or to avoid predators.New trilobite assemblage from the lower Cambrian (upper Stage 4) of the Lake Zone, western Mongolia.
