The early era, known as the Paleozoic, is divided into six periods. It starts with the Cambrian period, followed by the Ordovician, Silurian, Devonian, Carboniferous, and Permian. The major event to mark the Ordovician, more than 500 million years ago, was the colonization of land by the ancestors of modern land plants. Ordovician Period: 485 - 443 million years ago.

Famous Animals: Trilobites, nautiloids, early fish.During the early Paleozoic, the amount of carbon dioxide in the atmosphere was much greater than it is today. This may have begun to change later, as land plants became more common. As the roots of land plants began to infiltrate rock and soil began to form, carbon dioxide was drawn out of the atmosphere and became trapped in the rock.In some exposures, the.

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).
