Paleolithic Extinctions

Another major paper correlating the extinction of megafauna in N.A. with a celestial catastrophe -- in this reconstruction, a comet tail. Well worth reading & considering, IMHO. Click the pdf link at

Uniface,,Thanks for the link.It has always been shown through Quantum Mechanics and waves of Probability in Multi-Dimensional space// ie. metrical tensor.That these events are inevitable.
I come to the round conclusion that the expanding and contracting of all matter is like pin pointing the exacting of rock formations.This is why I like artifacts,and the study of why and when makes indeterminacy into something we can and must understand.Thanks again for the link/comanche

A couple more in addition to Firestone-Topping and Napier :

The Cause of the Megafaunal Extinction: Supernova or Galactic Core Outburst?

A Diffierent Kind of Catastrophe

Good stuff -- if you like that sort of thing : )
