The geologic time scale is a record that includes both geologic events and major developments in the evolution of life. The geologic time scale is divided into eons, eras, periods, and epochs. Timeline of prehistory. This timeline of prehistory covers the time from the appearance of Homo sapiens approximately 315,000 years ago in Africa to the invention of writing, over 5,000 years ago, with the earliest records going back to 3,200 BC. Prehistory covers the time from the Paleolithic (Old Stone Age) to the beginning of ancient history .plex history of the planet by studying layers of rock in the Earth’s crust. These layers contain fossils of plants and animals that lived on Earth, only a tiny fraction of which still exist today. By examining the composition of rocks and the types of fossils in them, scientists have created a timeline of Earth’s history.
All species of life—including humans—evolved into their present-day forms over the course of this era, which hasn't ended and most likely won't until another mass extinction occurs. Here is a brief look at the four periods of the Geologic Time Scale that track the Earth's history: Precambrian, Paleozoic, Mesozoic, and Cenozoic.Scientists divided Earth’s history into several chunks of time when the fossils showed similar things living on the Earth. They gave each chunk of time a name to help them keep track of how Earth has changed. ...

Earth is currently within the most recent interglacial period, which started 11,700 years ago and is commonly known as the Holocene Epoch. An intrusion is a body of igneous rock formed within Earth’s crust. When two features intersect, the one that cuts through the other is younger. This is known as the law of crosscutting relationships. Some strata contain index fossils, or fossils associated with a specific time in Earth’s history.
