6 Mya: Giants similar to humans began to flourish on Earth about this time and were still in evidence to about 200,000 BP. They seem to have survived some cold times. I imagine that the great Ice Age got their attention. During this time about 780,000 BP the Earth's magnetic field switched polarities and may have caught the attention of giganthropithicus. Around 200,000 years ago giants were rapidly losing ground and the massive eruption of Newberry caldera occurred in what is now central Oregon,  USA. At about the same time someone left a beautiful old stone age axe on a hillside of what is now Greece

6,400,000 BP: Heise volcanic field. Yellowstone hotspot. Walcott Tuff. Idaho, US. Ejecta volume was about 750 km3.

 5,333,000 BP to 2,580,000 BP, Pliocene epoch: This is beyond just pre-history. We can call this geological time. I am learning about this time, don't let me confuse you, I just have to begin somewhere. The Pliocene epoch follows the Miocene epoch. It is the second most recent epoch of the Neogene Period in the Cenozoic Era. Mastodons were big at the time.

I hope to be more explanatory and even more interesting on History With RCS

4,500,000 BP,USA: In what is now Idaho, in the Yellowstone hotspot zone, the Heise Volcanic Field erupted violently and ejected 1,800 km of stuff.

4,000,000 BP, Chile: In what is now the northern part of the country at the Pacana Caldera zone, the Atana Ignimbrite super volcano erupted ejecting about 2,500 cubic km of stuff.

2.6 Mya to 12,000 BP: This time marks the duration of the Pleistocene Epoch, which is followed by the Holocene epoch.

~ The Pleistocene is followed by the Holocene Epoch. As I remember the Holocene is the geological Epoch in which we are living.

 

2,588,000 BP: Included the Pleistocene Epoch which is followed by the Holocene Epoch,

2,480,000 BP, Argentina: Geologically speaking, ot so astoundingly long ago, there was colossal volcanic eruption at Cerro Gala'n in Andes' Central Volcanic Zone of Argentina, Catamarca Province 

2,588,000 BP: This date is in the Pleistocene epoch which is followed by the Holocene epoch.

 

2.48 Mya: Geologically speaking not so astoundingly long ago, there was a colossal volcanic eruption. It occurred at Cerro Galan, in the Andes Central Volcanic Zone in the Catamarca province of Argentina.

2,100,000 BP, USA: A volcanic eruption took place in what is now the Idaho and Wyoming region in the Yellowstone hotspot zone and called Huckleberry Ridge eruption. The approximate ejecta bulk volume was 2,500 sq, Km.  

1.76 Mya: Tool making by homo erectus may be traced back to this time.

1,080,000 BP, New Zealand: About this time there occurred a super eruption at what is now called the Mangakino caldera. One might hear it called the Kidnapper eruption.

25 Mya to 20 Mya

 25 Mya to 20 Mya

25,000,000 BP: what we have called the Laramide Revolution shook the Earth. It raised what is now the US state of New Mexico from below sea level to above sea level and so began a period of volcanism.

20.44 Mya, Burdigalian: Orogeny in northern Hemisphere. Start of Kaikoura Orogeny forming S0uthern Alps in New Zealand. Widespread forests slowly draw in massive amounts of CO2 gradually the level of atmospheric CO2.

23.03 Mya, Aquitanian: From a 6500 pmv CO2 level to around 100 ppmv during the Miocene. Modern mammal and bird families become recognizable. Horses and mastodons diverse. Grasses become ubiquitous.

 67,000,000 BP: An extraterrestrial object struck the Earth and marked the end of the the Cretaceous period and the beginning of the Tertiary period.

c.65,000,000 BP: It is said that a comet did enormous damage to our Earth. About this time an extraterrestrial object struck Earth and marked the end of the Cretaceous period and  the beginning of the Tertiary Period.
