  4. 1 TRIASSIC PERIOD • The First period • “Age of reptiles” • Crocodiles, turtles. • The earliest mammals evolved. • Small sizes (like a mouse) • Permanent extinction=extreme natural conditions

  5. E N V I R O N M E N T • The environment in all the period • Volcano eruption • Global cooling • Separation of the tectonic floor. • Extra= coral was already in the ocean it survive the terminal extinction

  6. 2 JURASSIC PERIOD • Dinosaurs were the most common animal • They rule about 150 million years in all the times • They evolved ( Archaeopteryx)

  7. E N V I R O N M E N T • At all the Jurassic • Hot and dry • The season were more notaries • Flower plants evolved • The laurasia and gondwana separation • Extra= sharks, rays, ammonites and crocodiles appear.

  8. 3 CRETASEOUS PERIOD • The longest period • The reptiles still rule • Giants Sauropod • Massive extinction (more than half of the animals and plants)=asteroid Ouranosaurus Mosasaurus

  9. E N V I R O N M E N T • The beginning • Warm temperature • No polar ice • Sea levels were high • At the end • Several climate changes • Volcanic eruption • Sea levels were lower
