E102 Eras of Life /
Geological Time Scale
The geological time scale divides the history of the
Earth into units of time based on layers of rock
(strata). It is the very the foundation of earth
science. Paleontologists use it to date when various
species lived. This chart is essential to the study of
both earth and life science.
This poster presents each period of geological time
through a strip of illustrations. Each period is
introduced by informative text, followed by
illustrations showing life both on land and in the seas,
index fossils and a globe showing the position of the
continents.
This new edition incorporates an abundance of
additional information and illustrations. An
introduction now explains what the geological time scale
is, its significance and how it was created. The margins
now introduce important groups of animals and plants.
They complement the period illustrations that show how
the species changed over millions of years. Updated
graphics make it even more attractive.
This has long been one of our most popular titles and
this major revision makes it even more informative and
useful. Highly educational and perfect for display in
classrooms, homes, offices, laboratories and just about
anywhere that learning takes place. |
