Trilobites are extinct arthropods… distant relatives of modern lobsters, horseshoe crabs and spiders. They lived from the Lower Cambrian Period (521 million years ago) to the end of the Permian (240 million years ago.) Their emergence and extinction bookend the Paleozoic Age.

JustSaiyan:

The sixth layer is the oldest. See that line going through the layers? That only goes half way through the sixth layer. Use the hints guys.

JustSaiyan:

Also the fossils.
