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. Africa - Paleozoic, Fossils, Geology: The Paleozoic Era consists of the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian periods and includes two major mountain-building episodes.

Cambrian Period, earliest time division of the Paleozoic Era and Phanerozoic Eon, lasting from 538.8 million to 485.4 million years ago. The Cambrian System, named by English geologist Adam Sedgwick for slaty rocks in southern Wales and southwestern England, contains the earliest record of abundant and varied life-forms.

The Quaternary Period (2.6 million years ago to the present) is composed of the Pleistocene and Holocene epochs. The Holocene Epoch began 11,700 years ago and continues into modern time.

The major divisions of the Paleozoic Era, from oldest to youngest, are the Cambrian (538. ...

The Mesozoic Era contains three geologic time periods including the Triassic Period (250 mya to approximately 206 mya), Jurassic Period (206 mya to approximately 144 mya), and the Cretaceous Period (144 mya to 65 mya).
