In colorful depictions and key stratigraphic information, both Global and North American standards of this timeline are : $ A wallchart summarising the whole time scale, with paleogeographic reconstructions throughout the Phanerozoic, is included in the back of the book. The time scale will be an invaluable reference source for academic and professional researchers and students. The correct answer is A. The eon of the geological time scale that means "visible life" is the Phanerozoic. Explanation: The Phanerozoic Aeon is a division of the geological time scale that extends from ± million years to the present day. It replaces the Precambrian, which covers the time remaining since the formation of the Earth. Golonka, Jan, and Wolfgang Kießling. "Phanerozoic time scale and definition of time slices."

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 ( Phanerozoic time-scale book.

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. Additional Physical Format: Online version: Phanerozoic time-scale.

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.

cally, Phanerozoic time scale building went from an exercise with very few and relatively inaccurate radiometric dates, as used by Holmes (, ), to one with many dates with greatly varying.

The Phanerozoic Eon is part of the geologic timescale. This Eon consists of three major eras. The Paleozoic era, the Mesozoic era, and the Cenozoic era. The Paleozoic era is also called the.
