Precambrian Era . The Precambrian era dates from the beginning of the earth about 4.6 billion years ago. There was no life on earth during the Precambrian era. Paleozoic EraWe infer that ridge subduction may have occurred in this region during Late Carboniferous to Early Permian. Combined with previous studies, there are two ridge subduction events during the early and late Paleozoic in Inner Mongolia within the southeastern CAOB, which coincide with two large-volume magmatic flare-ups (300 ± 20 and 450 ± 20 Ma).Paleozoic Era, or Palaeozoic Era , Major interval of geologic time, c. 542-251 million years ago.Devonian Period, in geologic time, an interval of the Paleozoic Era that follows the Silurian Period and precedes the Carboniferous Period, spanning between about 419.2 million and 358.9 million years ago. It is sometimes called the 'Age of Fishes' because of the diverse and abundant fishes found in Devonian seas.The Paleozoic ("old life") era was the first and longest era of the Phanerozoic eon, lasting from 538.8 to 251.9 Ma. During the Paleozoic, many modern groups of life came into existence. Life colonized the land, first plants, then animals. Two major extinctions occurred.

The three eras within the Phanerozoic eon are the Paleozoic era (541 million to 252 million years ago) the Mesozoic era (252 million to 66 million years ago) the Cenozoic era (66 million years ago to the present) The Phanerozoic eon is the eon of abundant complex life.The Permian Period is a 47-year period beginning from the end of the Carboniferous Period till the beginning of the Mesozoic Era — the Triassic Period. It started approximately 298.9 million years ago and ended 252.2 million years ago, making it the last period of the Paleozoic Era that began 541 million years ago.The Paleozoic was also marked by several mass extinctions: geologically short periods of time during which large numbers of life forms died out. Mass extinctions occurred at the end of the Ordovician, the Devonian, and the worst one of all at the end of the Permian, when about 95% of all life on Earth died!Oceanic conditions and biological richness resulted in the greatest production of carbonate during the Paleozoic Era.
