I acknowledge the debate circulating around the hypothesized, YD impact is vicious and polarizing. Nevertheless there is no need to review 30 years of research of historical impact data. I think most people are aware of the possibility of an ET impactor. It has been all over the popular media even w...

When I first "broke into" this thread, my premise was once a theory lost mainstream support the theory is essentially "dead". We observe shortly after Firestone published his theory and for a year or so afterward, the theory found favor and was given serious consideration as a po...

If you've ever eaten at a North American restaurant, you will get more food than you can eat. The tradition continues. I recall reading that Siberian herds were nearly decimated by the time humans crossed over. Whatever they were doing with the beasts it seems logical they would have gone hunting fo...

When Clovis people arrived there was an ice-free corridor (or so the "consensus" believes) because the climate had warmed enough to melt some areas. Obviously it warmed enough to support animals but it was anything but plush. I personally think humans crossed the Bearing Strait because the...

What happened in Oz is not likely to be representative of NA, much of Oz is arid, with logically many fewer mega beasts than the much more fertile grassy plains of the northern latitudes. Roy. Dig, North America was experiencing a full blown ice-age. How moist and grassy do you think it was? Check ...

I must admit that I find the suggestion that Clovis man wiped out the big beasts a little unlikely. Roy. In Australia: http://en.wikipedia.org/wiki/Australian_megafauna New evidence based on accurate optically stimulated luminescence and uranium-thorium dating of megafaunal remains suggests that hu...

It does seem as if it is up to Firestone to defend his theory and his methods. He ran it up the flagpole, others have now fired on it. The ball is in his court. I do hope that he does not try to fall back on native american folklore for "evidence." however. I agree. The Miller McCune arti...

Hi Mr. Grondine, Among those who actually work with this time period, the acceptance of simple cometary impact is gaining. This is something we can examine. I would love to see the papers. Just as there were other hypotheses explaining the extinction of the dinosaur. And as a matter of fact, just as...

Nice to see you back Monk! Gaining ground, losing ground, neither makes for proof gentlemen, history has proven time and again that established theories end up being wrong. Time will tell. Roy. There is no established theory in this case, Digit. Its open for discussion and that's what I was hoping ...

I don’t have an opinion one way or another on the impact theory. Both sides seem to have evidence to support their views. Then what's the point of your post? If you take a point of view we can debate it, otherwise, you're a bystander. But, Monk, you are describing “consensus.” A word that has taken...

Hi Mr. Grondine, Stupidity, eh? Maybe stupid is continuing to support a theory that is proving increasingly improbable. As originally introduced by Firestone, the impact hypothesis was put forth as a possible explanation for forcing climate change coincident with and contributing to megafaunal extin...

The North American comet theory is dead.
May it rest in peace.

I think it was Monk who had a such a graphic representation of sea level changes. It was a while ago and I can't recall for certain. I still have the program which allows me to view the planet with any sea level I choose. It is limited in utility because I chose to reduce the view to only 10 x 10 d...

The majority of meteors are rocky chunks of debris, of which there are billions in the iner solar system. Many are perturbed from the asteroid belt. Comets are not the only source though meteor showers occur when we pass through the tail of a periodic comet. Most of those are various form of ice par...
