The Phanerozoic Eon is the most recent eon. The fiery beginning of Earth’s history is recounted in the Hadean Eon, which takes its name from the ancient Greek god of the underworld. During the Archean Eon, life began to emerge on Earth. Both dinosaurs and humans first appeared during the Phanerozoic Eon, which is currently ongoing. The Phanerozoic Eon includes both the Mesozoic Era and the Jurassic Period. Both of these eras are included in the Phanerozoic Eon.
