Fossil trilobites

Description: Trilobites are extinct arthropods related to modern spiders. These animals had legs, but the legs are rarely preserved. For protection, they could roll themselves into a ball. They were probably scavengers and predators, dwelling on the sea floor. There are a great variety of Trilobite specimens that can be used as guide fossils. This means certain types of fossils are found only at certain times, and can be used to date rocks and fossils.
