Precambrian
fossil record geologic time scale
The largest percentage of the earths surface is covered by water mainly the Oceans (about 71%).
The Earth's history is divided into geologic time periods, with the largest unit being eons, which are further divided into eras, periods, epochs, and ages. The current eon we are in is the Phanerozoic eon, divided into the Paleozoic, Mesozoic, and Cenozoic eras. Each division represents significant changes in Earth's geological and biological history.
The division of geologic time that makes up about 88 percent of Earth's history is called the Precambrian eon. It spans from the formation of Earth around 4.6 billion years ago to the beginning of the Phanerozoic eon around 541 million years ago.

First organisms formed, pangaea came together, homo sapiens lived. There are lots of good images on google.
