The geological time scale divides the history of the Earth into units of
time based on layers of rock (strata). It is at the very 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 within the
groups 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.
