Yup. I saw that on one of the TV documentaries titled The Barbarians, it covered all these guys.
Even more AMAZING is that since Uzbekistan is several time zones East of the Russian frontier with occupied Poland back then, the scientists entered the tomb in the late morning at EXACTLY the same moment that the Germans invaded Russia in the early AM.
strange that they should call Genghis Khan a barbarian when he did manage to really unite east, west and south
