Usually you have to remind me, I just wanted you to see it when I remember on my own. ;')
The Cycle of Cosmic Catastrophes:
Flood, Fire, and Famine
in the History of Civilization
by Richard Firestone,
Allen West, and
Simon Warwick-Smith
Just because we are getting older it doesn’t mean we are brain dead. ;-) I think, however, that this mammoth was long before the Catastrophy described by Firestone. A lot them from that time period were flash frozen and even with undigested buttercups in the stomach. It may have ended up in the river, been buried in sediment and become part of the permafrost for the next 40,000 years.
I too became very interested in Velikovsky about 45 years ago, read most of his books. I don’t agree with all his guesses, but it made me try to find other answers to conventional “truths”. I have a book somewhere in the house about Alaska which talks about great masses of animal bones slowly washing out of a cliff. Will try to find it and add here.
