  3. Content Objective: Students will learn about some of the extinct species of mega fauna that lived in North America before the mass extinctions of 9,000 years ago, and the causes of those extinctions. Language Objective: Students will listen, discuss and write vocabulary related to the Pleistocene extinctions of mega fauna. In pairs, students will discuss the significance of the mass extinctions and apply the vocabulary to a graphic organizer (concept map).

  4. Terms to Know • Mega fauna: BIG ANIMALS! • Pleistocene:1.7 million years ago to 10,000 years ago • Ice Age: period of extreme cold, when glaciers covered continents • Glacier:a large sheet of ice, that is miles high • Land Bridge: a large land mass that linked Asia to North America • Herbivore: plant eater • Carnivore: meat eater • Overkill Theory: Humans killed all the mega fauna • Climate Change: The end of the Ice Age killed the mega fauna • Mass Extinction: many species of plants and animals die off in a short period of time

  16. THE BIG QUESTION: How did the mega fauna go extinct? Click Here http://www.ic.arizona.edu/~mmap/205_reid/lec08a.htm

  17. Theory #1: Climate Change Between 14,000 years ago and 8,000 years ago the Ice Age ended. North America today

  18. Climate Change Global Warming occurred between 14,000 and 8,000 years ago. Animals like mammoths could not adapt to the warmer and drier environment.

  19. Then….around 12,000 years ago, a new animal came to North America…. http://www.ic.arizona.edu/~mmap/205_reid/lec07a.htm Click Here

  20. Human tribes migrated from Asia to North America across a land bridge that is today covered by the sea. The warming climate helped humans colonize North America.

  21. Mammoth hunters were likely the “first” Americans. They are the ancestors of most Native Americans. Large spear points were used to hunt mammoths. Click Here!

  22. Theory #2: Pleistocene Overkill! Could human beings have hunted the Pleistocene mega fauna into extinction?

  23. Pleistocene Overkill Two hunters carry a mammoth tusk back to camp.

  24. Mass Extinctions of Mega fauna(13,000-9,000 years ago) OR Overkill Climate Change Many scientists believe that both over-hunting and climate change led to the mass extinction of mega fauna.

  25. End of the Pleistocene(9,000 years ago) Humans in North America adapted to the warmer climate, while the mega fauna went extinct.
