30% oxygen and two atmospheres of pressure must have really helped the elk hunters of 6,000 years ago climb those high mountains.
The partial pressure of oxygen at those conditions would be around 450 mm Hg and should present no problems to the reptile. Scuba divers are exposed to those levels of oxygen quite frequently. The temperature and humidity are fine for the snake. The electromagnetic field should have no more effect on a reptile than it did on most of the other animals alive 6,000 years ago.
I dare say you will have another set of answers that will be very interesting to read. This is getting quite entertaining.
A drop in the pressure of oxygen from 450 to 160 in only 6,000 years is fascinating. I want to hear more about that. Have you contacted CNN about this?
