Geologists have a new name for the past 4,200 years: The Meghalayan Age. 

Years of research have gone into studying this age. 

It is said to have started with a drought and cooling, which disturbed and destroyed civilizations across the globe. These agriculture-based societies collapsed during this 200-year climactic disaster and people who didn't perish migrated toward places like Greece, Egypt, and Mesopotamia. There is evidence of this event throughout all seven continents.

There are three subdivisions: Greenlandian, Northgrippian, and Meghalayan. Updated now to include the new distinct age, this chart depicts a thorough, complete timeline for the geologic history of the Earth. 

Here is a more detailed breakdown of the International Chronostratigraphic Chart:

Greenlandian is the earliest stage, covering climactic and geological events that happened 11,700 - 8,300 years ago. Northgrippian is the middle stage, covering that of 8,300 - 4,200 years ago, and the new Meghalayan stage covers events spanning from 4,200 years ago to now. 

Together, the three ages make up the Holocene Epoch. 

We are now living in the Meghalayan Stage of the Holocene:

Twitter was curious about the name of the new age:

Sediments from the MawmluhCave in Maghalaya, India, aided in defining and naming this period, which represents the entire written history of humanity.  

It is named after the MawmluhCave in Maghalaya, India:

Meghalayan, which means "the abode of clouds" in Sanskrit, is a relatively unknown state in Northeast India. The population is a bit more than three million people, and more than half of the state is forested.

Residents are pretty excited about the dedication:

Welcome to the Meghalayan Age. 

Thanks, Science!
