The Precambrian (or Pre-Cambrian) is an informal name for the eons of the geologic timescale that came before the current Phanerozoic eon. It spans from the formation of Earth around 4500 Ma (million years ago) to the evolution of abundant macroscopic hard-shelled fossils, which marked the beginning of the Cambrian, the first period of the first era of the Phanerozoic eon, some 542 Ma.

  • The Precambrian was the first supereon in Earth's history, lasting from the formation of the Earth to the Cambrian period. During this time, the Earth's atmosphere was high in sulphur and carbon dioxide, consisting of a green, fog-like sulphuric gas, and Precambrian Worms thrived.
