Comprising of the Paleozoic, Mesozoic and Cenozoic eras, this eon spans 541 million years from the Cambrian Explosion to today.
During the Paleozoic era, complex
life started to appear. It took 100 million years for the aquatic plants and animals to migrate to land. Then, another 130 million years
later, giant bugs started to appear.
60 million years later, entire coalfields from the Carboniferous Rainforest Collapse Event were
set on fire by volcanic activity, causing the Permian-Triassic extinction. The Mesozoic era had begun.
20 million years later, dinosaurs started to appear. They died altogether during the Cretaceous-Paleogene extinction
66 million years ago beginning the Cenozoic era. The mammals started to dominate land. 60 million years later, the Mediterranean Sea drained up, but quickly refilled due to closure and reopening of the Strait of Gibraltar. 6 million years later,
humans finally appeared, ending the story of
earth's
life as we knew it.
