三葉蟲 (trilobites)在地球的海底裡繁衍了幾百萬年，從化石的研究記錄裡顯示，它們大約生活在5億4000萬年前的寒武紀初期。在當時的寒武紀生物爆發(Cambrian explosion) 後，不同的生命開始繁衍。三葉蟲逐漸滅亡的時間是介在3億-2億4000萬年前，尤其在二疊紀和三疊紀交界時期 (Permian-Triassic boundary)(2億4500-2億5100 萬年前)的滅絕事件後，三葉蟲即消失在化石記錄裡。它們類屬於節肢動物 (arthopods), 但它們的物種是否更接近甲殼類 （crustations）、蟹類 (cheliceramorpha)(馬蹄蟹、海蝎子和蜘蛛網的動物)或海蜘蛛網 (pycnogonida)(海蜘蛛) ，目前我們尚未有全面的了解。

- The Trilobites website has great pages about trilobite life (Sam M. Gon III).
- An Australian Museum Online site about the trilobites.
- The Fossil Museum has interesting pages about trilobites.
- The Peronopsis interstricta (or some other Agnostida?) trilobite fossils shown on this page were found near Delta, Utah close to the private U-Dig fossil quarry, a commercial outfit that gives people a chance to find trilobite fossils.
- Many trilobite fans have created websites full of photographs of trilobite fossils. This is one of the better ones, by Mark Bourrie.
