Ah well...
You just blew out of the water my next post.
Dino's are somewhat subject to question...in my mind...but MegaFauna are
rather more specifically documented. I beleive there ARE bones of those
critters still around...not just fossils of bones.
And if a Wooly Mammoth was twice the size of an elephant...ditto (cave bear,
and kitty kat)...then my speculation on tissue tensile strength and bone
compression strength just got blown away.
Too bad...
