Recent Ice Ages; Death of Mega-fauna
- Tarantian (Upper) 0.0117–0.126 Ma
- Ionian (Middle) 0.126–0.781 Ma
- Calabrian (Lower) 0.781–1.806 Ma
- Gelasian (Lower) 1.806–2.588 Ma
What happened during this time?
- The severe climatic changes during the ice age had major impacts on the fauna and flora.
- With each advance of the ice, large areas of the continents became totally depopulated, and plants and animals retreating southward in front of the advancing glacier faced tremendous stress.
- There has not been and ice-free period in the Arctic Ocean for 2,6 million years (although that may be quickly changing)
- The most severe stress resulted from drastic climatic changes, reduced living space, and curtailed food supply
- Extinction event of mega-fauna took place between 11.4-13.8 Ka (Faith 2013)
- Quick disappearance seems to indicate a sudden catatrophic event such as human over-hunting or cosmic impact
- Origin of the genus Homo around 2.3 - 2.4 Ma
