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.
