Precambrian - Precambrian - Precambrian geology: By international agreement, Precambrian time is divided into the Archean Eon (occurring between roughly billion years ago and billion years ago) and Proterozoic Eon (occurring between billion and million years ago).
After the Precambrian, geologic time intervals are commonly subdivided on the basis of the fossil record. COVID Resources.
