The geologic time scale is a systematic sequencing of stratigraphy. It is used by geologists, paleontologists, and other Earth scientists to explain the timing and relationship of events in geological history. The time scale is formed by studying the layers of rock layers and relationships and when various species appeared, evolved, and disappeared by studying fossils and texts.
The Cambrian period was the first Geological period of the Paleozoic Era and the Phanerozoic Eon. Cambrian lasted 54 million years from the end of the Ediacaran Period, 542 million years, to the beginning of the Ordovician Period, 488 million years. Cambrian has shown a dramatic change in life on Earth. The Earth was very cold at the beginning of Cambrian, probably because of the ancient continent of Gondwana that covered the South Pole and cut through the ocean currents.
