Trilobites are extinct arthropods that dominated the faunas of the oceans of the Paleozoic era. During their time on Earth, which lasted much longer than the dinosaurs, between 521 and 252 million years ago, they survived two major episodes of mass extinctions and dominated ocean floor ecosystems. There are more than 20,000 known trilobite species.
