Phanerozoic Eon

The Phanerozoic Eon is the most recent and longest of the three eons in the geologic time scale. It is an interval of time beginning 541 million years ago, covering the present day and stretching all the way back into the Precambrian Era. During this time period, plants and animals have evolved and diversified, leading to the complexity of life that we see today. The Phanerozoic Eon is a crucial time period in the history of life on Earth, as it marks the emergence of multicellular organisms and the development of the continents and oceans. The Phanerozoic Eon is important for its many geological, climatic and evolutionary milestones. It has been essential for the study of earth’s geologic past, and is also useful for understanding current climate change.
