The Paleozoic era, meaning “ancient life”, is a division of earth’s history spanning from around 541 to 252 million years ago. It is subdivided into the Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian periods. The beginning of the Paleozoic is characterised by the sudden appearance of animal ecosystems following the extinction of the Precambrian Ediacaran fauna. The end of the Paleozoic is marked by the greatest mass extinction in earth’s history, following which global ecosystems were radically reorganised.
