Re: Expanding Earth and Shrinking Animals
You could fill twelve pages with the scientific reasons that this theory is not valid.
Most obvious is the fact that skilled paleontologists studying bone densities, biologies, metabolic rates, etc. have never found any plausible reason that any dinosaur was not perfectly compatible with a gravity field of about 1 G and a normal atmospheric pressure.
Not sure why this even came up. What's next? Velikovsky? It's tough enough arguing the plausible stuff without having to swat these flies.
