N.Biliskov,

That collective (pioneering) research effort was nothing short of amazing in 
the personal difficulties to gather evidence under the conditions of a 
"sterile" Mongolian site.

I have read, as others have, that report a number of times and will 
doubtless read it again.

It is a ground breaking research direction only begun. LS.
