Timeline on Paleoclimate #0:
This is the waaaay early part of my timeline; edits or comments welcome. It’s going from 35.7 mya to .5 mya, with special note to the major level 8 eruptions, big impacts, and a smattering of human development events thrown in. There are different colors for events - orange for impacts, red for eruptions.

25,000,000 ya: Turkey Creek Eruption (Arizona)
23,030,000 ya: Miocene begins.
Note: Seeing all of these volcanic eruptions with big output, it’s amazing that anything stuck around in the western US area.
16,500,000 ya: Yellowstone hotspot arises in the Idaho/Oregon/Nevada juncture and slowly tracks across Idaho in an arc towards Yellowstone.

Habilis arises in Africa
2,150,000 ya: Eltanin impact (Ocean off Australia, Bellinghausen Sea )
200-300 m high tsunami to the Antarctic Peninsula and the southern tip of South America 1200-1500 km away. 60 m waves would have struck New Zealand, 6000 km away.
