Life During the Paleozoic. The Paleozoic Era is literally the era of “old life.”. It lasted from 544 to 245 million years ago and is divided into six periods. Major events in each period of the Paleozoic Era are described in Figure below. The era began with a spectacular burst of new life.All the animals and plants of the early Paleozoic Era lived in the sea; there was no life on the land. In subsequent periods of the Paleozoic Era, invertebrates such as octopuses, shelled mollusks, corals and starfish evolved, along with the first fish, amphibians and reptiles.MIT geologists have now reconstructed a timeline of the Earth's temperature during the early Paleozoic era, between 510 and 440 million years ago -- a pivotal period when animals became abundant ...The Cambrian period, part of the Paleozoic era, produced the most intense burst of evolution ever known. ...

The Phanerozoic eon is the most recent eon and represents time in which fossils are common, 541 million years ago to today. An early Carboniferous age for the ophiolite is supported by Rb–Sr isochron geochronology of basaltic rocks (Jiang, 1992, Mattern et al., 1996), whereas other authors suggest Neoproterozoic–early Paleozoic ages (Deng, 1995, Xiao et al., 2003).
