See Timetable of the Precambrian. 1  Proterozoic: this eon refers to the time from the lower Cambrian boundary, 541.0 Â± 1.0 Ma, back through 2500 Ma.
The Precambrian covers almost 90% of the entire history of the Earth. It has been divided into three eras: the Hadean, the Archean and the Proterozoic. . Source: Unknown. The Precambrian Era comprises all of geologic time prior to 600 million years ago. The Precambrian was originally defined as the era that predated the emergence of life in the Cambrian Period.
