What is paleozoic era
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. This is called the Cambrian explosion.What is the duration of the Paleozoic era? The Paleozoic Era is literally the era of "old life.".

Paleozoic Era. Oregon's oldest known rock formations are found in the Blue Mountains and the Klamath Mountains. The state's oldest individual rock is a limestone near Suplee dated to nearly 400 million years ago, during the Devonian period of the Paleozoic era. These deposits include conodonts as well as extinct corals and brachiopods, indicating a shallow marine environment.The Precambrian, Paleozoic, Mesozoic, and Cenozoic Eras.

The Paleogene and Neogene (about 66 to 2.6 million years ago) are remarkable for their great tectonic movements, which resulted in the Alpine orogeny.The era is bounded by two mass extinctions at the end of the Paleozoic Era and the beginning of the Cenozoic Era, and is known as the Age of Dinosaurs.
