Palaeozoic

Palaeozoic(Paleozoic) The first of the three eras of the Phanerozoic, about 570–248 Ma ago. The Cambrian, Ordovician, and Silurian Periods together form the Lower Palaeozoic Sub-Era; the Devonian, Carboniferous, and Permian the Upper Palaeozoic Sub-Era. It was an era of great evolutionary change among plants, which began to invade the land at its beginning. By the end of the era, amphibians and reptiles were major components of various communities and giant tree-ferns, horsetails (Calamitaceae), and cycads gave rise to extensive forests. The faunas of the Palaeozoic are noted for the presence of many invertebrate organisms including trilobites, graptolites, brachiopods, cephalopods, and corals. The name is derived from palaeo- and the Greek zoe, meaning ‘life’.

Palaeozoic

Palaeozoic The first (570–248 Ma) 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 Variscan 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.

Palaeozoic

Palaeozoic Second era of geological time, after the Precambrian era, lasting from 590 million to 248 million years ago. It is sub-divided into six periods: Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian. Invertebrate animals evolved hard skeletons capable of being preserved as fossils in the Cambrian; fish-like vertebrates appeared in the Ordovician; amphibians emerged in the Devonian; and reptiles in the Carboniferous.
