It was only 75,000 years ago that Toba exploded and only about 2,000 humans worldwide survived.
It's a good day when they do.
That's sort of hard to buy off on. As I understand it you've got a couple of dating systems including dendrochronology and radiocarbon dating which will date things from the present back to about 30,000 years ago and then you've got decay type dating systems which will let you fix approximate dates in millions of years, but I'm not really aware of anything which will fix dates in the 50,000 - 100,000 year old range.

Interesting read! I am curious about the Soulitean travelers Could a north atlantic Atlantis type of land bridge have been the key? Trade between Ireland and Spain is historic.
