The Phanerozoic is the current geologic eon in the geologic time scale, and the one during which abundant animal life has covers roughly million years ( ± ) and goes back to the time when diverse hard-shelled animals first appeared.

Phanerozoic Eon, the span of geologic time extending about million years from the end of the Proterozoic Eon (which began about billion years ago) to the present. The Phanerozoic, the eon of visible life, is divided into three major spans of time largely on the basis of characteristic assemblages of life-forms: the Paleozoic ( million to million years ago), Mesozoic ( million.

The Phanerozoic Eon is the current geologic eon in the geologic time scale, and the one during which abundant animal and plant life has existed. It covers million years to the present, and began with the Cambrian Period when animals first developed hard shells preserved in the fossil record.

The time before the Phanerozoic, called the Precambrian, is now divided into the Hadean, Archaean. An international team of over forty stratigraphic experts have helped to build the most up-to-date international stratigraphic framework for the Precambrian and Phanerozoic.

[Gavin C Young; J R Laurie; Australian Geological Survey Organisation.;] -- This book gives a new global perspective on the Phanerozoic timescale, by bringing together extensive Australian and overseas research on biostratigraphy, geochronology, and magnetostratigraphy.

For. The general acceptance of plate tectonics and continental drift by the early s galvanized the study of biogeography and our understanding of the origin and evolution of life.

However, until now the accumulated information has been widely scattered in the literature. This book is the first to synthesize the results of over two decades of prolific research in a clear, concise format.

Geochronology - Geochronology - Completion of the Phanerozoic time scale: With the development of the basic principles of faunal succession and correlation and the recognition of facies variability, it was a relatively short step before large areas of Europe began to be placed in the context of a global geologic succession.

This was not, however, accomplished in a systematic manner. The Paleozoic time scale relies strongly on the data of Tucker and McKerrow () for the Cambrian to Silurian.

This is justified by the density of radiometric age data obtained and compiled by Tucker and McKerrow ().However, owing to new chronostratigraphic data of Huff et al.

The Phanerozoic Eon. The Phanerozoic Eon is a period of geological history that spans million years and is typically subdivided into three eras.

These eras are: Paleozoic Era: to Phanerozoic carbonates and concluded that dolomite abun- dances do vary significantly throughout the Phanerozoic but may not increase systematically with age.

Figure 3 is a sum- mary of the global data set for Phanerozoic dolostone abun- dances from WILKINSON and ALGEO (). The percent. Phanerozoic Reef Patterns presents a comprehensive and up-to-date review on the history of reef building in the last million years. A selection of internationally respected reef specialists presents a database on ancient reefs that is hardly available for any other ecosystem.

The revised () Phanerozoic time scale incorporates and suggests some systematic regularities at the Period level. If one considers the Cenozoic Era as equivalent to the other geological Periods, and if one combines the Triassic-Permian and Devonian-Silurian Periods, 8 major subdivisions of Phanerozoic time result which group into two distinct populations of 66±3 and 78±1 m.
