  2. ANIMALS OF THE CENOZOIC ERA!

  3. TIME PERIOD

  4. TIME PERIOD • 65 Million Years to the Present • shortest era • Starts from the end of the Cretaceous. • and the extinction of non-avian dinosaurs to the present.

  5. Where fossils were located?

  6. NAMES FOR THIS ERA • Age of mammals • Age of flowering plants • Age of Insects • Age of birds

  7. PALEOGENE PERIOD • Climates changed from warm and moist to cool and dry. • Some pants developed flowers and insects expanded. • Some large mammals evolved and the first whales evolved.

  8. Neogene period • The continents collided and found modern mountains chains • The Neogene Period began about 24 million years ago • Connections between continents where created.

  9. Consequences • The mountains changed environment so animals had to change to adapt. • Continents positions changed ocean currents which changed the weather. • Connections between continents caused land animals migrations.

  10. Quaternary Period • During the quaternary period the positions of the continents were much the same as they are today • Various ice ages that come and go. There was so much frozen water that sea level fell over 100 meters Between 6 and 7 million years ago a group of mammals began an adaptive radiation that will lead to modern humans.

  11. Theage of humans • The first homo sapiens occurred around 190,000 year in Africa. • Some scientists have concluded that the big mammals of the quaternary age disappeared because the hunting methods of humans. • As the brain got bigger, and we became smarter migrations to other continents occurred. • During ice ages humans migrated to equator looking for warmer land , but as glairs melted they returned to the north. • The low seas permitted easier migrations to continents.

  12. Somefacts • If earth history was compressed in one hour, flowers will only exist for the last 90 seconds., and humans for the last 7 seconds. • Some birds where 7 feet tall. • Which was the biggest mammal ever? • Indricotherium
