MONTESSORI THE GREAT LESSONS : The Triassic Period



 The Coming of Life



 The Triassic Period

 The name of this period means
 three because its rock sediments are
 divided into the strata. It also marked
 the beginning of the Mesozoic Era
also called the Age of Reptiles.





 This is the earliest period 
of the Mesozoic Era. The reptiles were 
the first to live and lay eggs on the land, 
though some went back to the water.





The reptiles overshadowed all the
other animals, having no enemies
 they were able to multiply and 
develop into great dinosaurs. 





  This was a very warm period.
The dinosaurs could resist the heat 
of the sun due to their amour-like
 skin covering. They were both 
vegetarian and carnivorous.





The carnivorous reptiles had 
terrible teeth. The reptiles laid eggs
 on the land - but these eggs needed 
moisture so the reptiles formed a shell 
around the moist egg. They left them
in the sun which hatched them.





 Other species, the flying reptiles,
developed wings and membrane 
similar to the wing of the bat.
