Who said those bones were inside a living creature when the glacier scooped them up?
No one.
All I'm saying is the standard models of biology, geography and climatology descibing some area of the vast northern wilderness do not seem to add up.
And I would think if this was simple glacial moraine type material, this would have been pointed out long ago. And I have never heard anyone proposing that as the sole explanation.
There are still islands in northern Russia that have tens, if not hundreds of thousands of mammoth tusks lying around. So whatever gives, it seems to not just be a couple thousand years where things gradually warmed up.
And alot of these areas - even now, not in an ice age climate, would be hard pressed to provide enough for a meal for you or I, not to mention a few starving, po'd mammoths.
