- Precambrian starte about 4600 million years ago and ended in 500 million years ago. Based on carbon dating of rocks found 3.8 billion years ago life forms started to emerge, and evidence of plate tectonics motion can be 4280 million ago.
- As compared to the phanerozoic era which started from 500 million years ago to present studied as an era of diverse land and aquatic plants and animals. Subdivided as Paleozoic Era, Cambrian Period, Ordovician Period,Silurian Period, Devonian Period, Carboniferous Period and Permian Period.
