Paleo Earth

Evidence from radiometric dating indicates that Earth is about 4.54 billion years old. The deep time of Earth's past has been organized into various units according to events which took place. Different spans of time on the Geologic time scale are delimited by changes in the composition of strata which correspond to them, indicating major geological or paleontological events, such as mass extinctions, for example the Cretaceous–Paleogene extinction event, which marked the demise of dinosaurs

The Archean is one of the four principal eons of Earth history. When the Archean began, the Earth's heat flow was nearly three times as high as it is today, and it was still twice the current level at the transition from the Archean to the Proterozoic    http://space-telescopes-news.blogspot.com/2010/03/archean.html

The Geologic Time Chart is a tool devised by geologists to assist in the comprehension of the 4.5 Billion Years of Time represented in the layers of rocks and fossil remains found on Earth and provides a meaningful time frame within which the events of the geologic past are arranged.

The fossil record from latest Precambrian is sparse, as more easily-fossilized hard-shelled animals had yet to evolve. The Ediacaran biota include the oldest definite multicellular organisms with tissues, and the most common types resemble segmented worms, fronds, disks, or immobile bags.

The Earth began to form about 4.54 billion years ago through the condensation of material around the sun. As this material collected, further cosmic material was drawn to it by gravity from all directions, increasing the size of the Earth. This process created an enormous amount of heat, which melted these materials and eventually allowed them to separate into different layers.

The Sturtian and Marinoan glaciations, which are the greatest ice ages known to have occurred on Earth, occurred during Cryogenian period.
