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.
Best Answer: Geological Period that lasted the longest: The Precambrian Era. The Precambrian Era is the longest geological era beginning 4.5 billion years ago and lasting approximately 4 billion years. The Precambrian era is generally separated into two eons the first of which being the Archaean Eon. spanning from around 4.5 billion years ago to 2.5 billion years ago, during this time air temperatures lowered and the water vapour condensed forming the first primeval oceans.
