  • 100 BCE

    100-23 Million Years Ago

    • Interaction of animals and plants during late Cretaceous and Paleogene period created third rapid coevolution of animals and trees.

    93 Million Years Ago

    • Large underwater volcanic eruption wiped 27% of marine invertebrates out, oxygens depleted from the ocean
    -
  • 80 BCE

    80 Million years ago

    • North America separated from Europe, Australia and Antartica separated from rest of the continenets
    • More separation of continents, plate tectonic collisions formed Mountains (Himalaya)
