I guess you have missed Sunken Civ’s numerous postings of Firestone et al.’s recent book on this subject. Google the author, or perhaps SC will post it again. It is very interesting read and pulls together numerous and widespread anomolies and explains them.
My memory not being what it used to be, for example, I don't recall much if anything in the book about enormous waves or widespread flooding that could have occurred that may explain artifacts found in unbelievable numbers and in the oddest places around the globe. But that may be more a factor of my memory than their book. I'll have to re-read it one day. I'm presently re-reading one of Velikovsky's works that I had trouble assimilating on first read.
Thanks for the heads up.
