Phanerozoic

The Phanerozoic /ˌfænərɵˈzoʊɪk/ (British English Phanærozoic) is the current geologic eon in the geologic time scale, and the one during which abundant animal and plant life has existed. It covers 541.0 ± 1.0 million years and goes back to the period when diverse hard-shelled animals first appeared. Its name derives from the Ancient Greek words φανερός (fanerós) and ζωή (zo̱í̱), meaning visible life, since it was once believed that life began in the Cambrian, the first period of this eon. The time before the Phanerozoic, called the Precambrian supereon, is now divided into the Hadean, Archaean and Proterozoic eons. Plant life also appeared from early in the Phanerozoic eon.The time span of the Phanerozoic includes the rapid emergence of a number of animal phyla; the evolution of these phyla into diverse forms; the emergence and development of complex plants; the evolution of fish; the emergence of insects and tetrapods; and the development of modern faunas. During this time span tectonic forces caused the continents to move and eventually collect into a single landmass known as Pangaea, which then separated into the current continental landmasses.
