Earth's latest phase named Meghalayan Age after Indian state
The most recent age in Earth's 4.54-billion-year history started 4,200 years ago and has been named the Meghalayan Age, after the Indian state. The designation comes after the discovery of a stalagmite rock in Meghalaya's Mawmluh cave. The rock's chemical signature indicated a substantial weakening monsoon, making it the first official marker of a geological time period change in India.
