					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. |
