MONTESSORI THE GREAT LESSONS : The Paleozoic Era



 The Coming of Life



 The Paleozoic Era

The Paleozoic Era is the first and 
longest era for which an abundant 
fossil record exists; hence its name, 
which means "ancient life" in Greek.



This is the "Age of Invertebrates".
Life in the sea continues to develop - 
crinoids, trilobites, branchiopods 
and the first worm like fish.



 The sea became so overcrowded
 that the fish are forced to explore the
 land and adapt into amphibians. The
 first mosses appear on land followed
 by the first plants. Giant ferns, horsetails
 and club mosses cover the land in forests
 at the end of this era. Large flying insects.
