Greenlandian
In the geologic time scale, the Greenlandian is the earliest age or lowest stage of the Holocene epoch or series, part of the Quaternary. It is one of three subdivisions of the Holocene. The lower boundary of the Greenlandian Age is the GSSP sample from the North Greenland Ice Core Project in central Greenland. The Greenlandian GSSP has been correlated with the end of Younger Dryas and a "shift in deuterium excess values".
The age began 9700 BCE or 300 HE.
The age was officially ratified by the International Commission on Stratigraphy in July 2018 along with the Meghalayan and the Northgrippian.
