Palaeozoic

Biology

The first era of Phanerozoic time. It follows the Precambrian and is subdivided into the Early Palaeozoic, comprising the Cambrian, Ordovician, and Silurian periods, and the Late Palaeozoic, comprising the Devonian, Carboniferous, and Permian periods. It extended from about 541 million years ago to about 252 million years ago, when it was succeeded by the Mesozoic era.

Geology and Earth Sciences

The first (542–251 Ma ago) of the three eras of the Phanerozoic. The Cambrian, Ordovician, and Silurian periods together form the Lower Palaeozoic sub-era; the Devonian, Carboniferous, and Permian the Upper Palaeozoic sub-era. During the Palaeozoic, two major orogenies occurred: the Caledonian during the Lower Palaeozoic, and the Hercynian in late Palaeozoic times. The faunas of the Palaeozoic are noted for the presence of many invertebrate organisms, including trilobites (Trilobita), graptolites (Graptolithina), brachiopods (Brachiopoda), cephalopods (Cephalopoda), and corals. By the end of the era, amphibians and reptiles were major components of various communities and giant tree-ferns, horsetails, and cycads gave rise to extensive forests.
