How many years is a "long time"? We often express time in hours or days, and 20 or 30 years certainly feels like a long time. Imagine if you needed to think about one million, 100 million, or even several billion years. These exceptional lengths of time seem unbelievable, but they are exactly the spans of times that scientists use to describe the Earth.

In developing the current Geological Society of America Time Scale, we have strived to maintain a consistency with efforts by the International Commission on Stratigraphy to develop an international geologic time scale. Although current geologic time scales are vastly improved over the first geologic time scale, published by Arthur Holmes in 1913, we note that Holmes, using eight numerical ages to calibrate the Phanerozoic time scale, estimated the beginning of the Cambrian Period to within a few percent of the currently accepted value.

These key events frame the chapters in the story of life on earth and the system we use to bind all these chapters together is the Geologic Time Scale. Thanks to Studio 252mya for their illustrations.

The geologic time scale (GTS) is a system of chronological dating that relates geological strata (stratigraphy) to time

The geologic time scale (GTS) is a system of chronological dating that relates geological strata (stratigraphy) to time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth's history. The table of geologic time spans, presented here, agree with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy (ICS).
