  4. Geologic Time Scale Coach p. 237 Textbook p. A64 Dictionary p. 148 Era

  5. Most recent “Ice Age” QUARTERNARY “Humans” arrive TERTIARY Major Mass Extinction Age of Dinosaurs Major Mass Extinction Age of Coal Formation Geologic Time Scale Age of Fishes First multi-celled organisms Origin of the Earth 4.6 Billion years

  6. A Brief view of the History of Life on Earth Early earth 4.6 BYA

  7. Early earth 4.0 BYA

  8. Stromatolites- cyanobacteria 3.8 BYA – 630 MY Shark Bay, Australia

  9. Ediacaran 630 – 570 MYA - More complex organisms (soft tissue)

  10. Cambrian (Burgess shale) -1st hard shelled fossils -trilobites dominant 570 - 505 MYA

  11. Ordovician -appearance of coral reefs -nautiloids dominant -limestone formation -Predators 505 - 438 MYA

  12. Silurian -appearance of fish 438 - 408 MYA

  13. Silurian Fish 438 - 408 MYA

  14. Devonian -land plants become common -1st land animals 408 - 360 MYA

  15. Devonian -1st amphibians 408 - 360 MYA

  16. Carboniferous -Pennsylvanian (290-320mya) -Mississippian (320-360mya) -extensive marine life (coral reefs); flora (crinoids) -brachiopods; giant insects -extensive tropical forests 360 - 286 MYA

  17. Dimetrodon Permian -Primitive reptiles -shallow marine life (sponges/clams) -reptile-like creatures become large -at end largest mass extinction ever (>90%); large volcanic eruptions 286 - 245 MYA

  18. Triassic -Age of Dinosaurs 245 - 208 MYA

  19. Jurassic “Age of Reptiles” -large dinosaurs dominant 208 – 144 MYA

  20. Jurassic -fish, marine reptiles dominant 208 – 144 MYA Plesiosaur

  21. Cretaceous mammals, birds appeared 144 - 65 MYA

  22. Cretaceous 144 - 65 MYA Cretaceous extinction 65 MYA

  23. Paleocene -marsupials -after KT extinction of dinosaurs 65 - 58 MYA

  24. Eocene -modern mammals 58 – 37 MYA Earliest Bat Pygmy Horse

  25. Miocene 24 – 5 MYA

  26. Pliocene 5 MYA Australopithecus spp.

  27. Pleistocene 2 MYA - 100,000 YA Cave Bear

  28. Pleistocene 2 MYA – 100,000 YA Homo habilis
