The Precambrian or Pre-Cambrian; sometimes abbreviated pÐ is the largest span of time in Earth's history before the current Phanerozoic Eon, and is a Supereon divided into several eons of the geologic time scale.he Precambrian Supereon is divided into three eons: the Hadean (4500-3950 Ma), Archean (4000-2500 Ma) and Proterozoic (2500-541.0 Â± 1.0 Ma). 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 is usually considered to have three eons: the Hadean, the Archean and the Proterozoic. Some scientists recognize a fourth eon, which they call the Chaotian, which predates the others and is the time of the first formation of our solar system.
