You'd die on arrival, this is about oxygen levels:

... the new figures suggest that during the Early Devonian, levels first rose from about 22% to nearer 25%, but then dropped precipitously through most of the rest of the Devonian until the end of the Frasnian, at which point they were as low as 13%. Levels then rose slowly to reach about 16% by the end of the Famennian. They only reached present levels by the mid-Viséan (Fig. 2).

yep. 21% of oxygen for 7 billion people but if one person lands in an atmosphere with a 13% oxygen level, they will die instantly.

Breathe slow, fill your time pod with plants.
Find water, learn to fish and you'll go on to become your own granddad.

Why would I want to survive ALONE, with ZERO chance of ever getting back?
Boredom alone would drive you crazy.

I meant that I'm pretty sure that even with dispersed oxygen molecules, you could still breathe fine. probably
Even if we did survive, there's no reason for our survival.

Its about the concentration gradient of oxygen between the air and your blood. The minimum concentration of air oxygen to be considered breathable for a human who isnt hypoxia trained is 19.5%. Under that you have serious problems because not enough oxygen is diffusing into your blood and you die

Quoted By:

If oxygen isn't a problem as cited by the faggots in the thread, then I'd dig a big hole, smother myself in mud, and start building small tools and infrastructure. Assuming I could somehow make it near mountains or hills and fresh water, I could survive by making an intricate tunnel system with small rooms to live in. From there I would create a rape dungeon for small captured dinosaurs and have sex with them while forcing them to breed and eat their offspring, egg or children. I'd have a dino wife and plenty of sex slaves. Eventually I would die because I know nothing of iron making or serious medical ability.

Strictly speaking, isn't the requirement the partial pressure of oxygen? Not that that helps any without a compressor.
