Вече се знае, че не е вярно http://www.mysteriousearth.com/archives/000037.html (по името на сайта мога да предположа, че е един от вашите :) :

Dating a carved slab of stone is a nearly impossible task, and in the case of the Dashka Stone, it has lead to some very strained conclusions. Of the few datable materials on the map, there are a few fossilized shells: a 500 million year old specimen of Navicopsina munitus of Gyrodeidae family and a 120 million year old specimen of Ecculiomphalus princeps of Ecculiomphalinae subfamily. The shells are apparently used as markers upon the map itself. Some followers of the Dahska investigation have used this evidence to assert that the map must be 120 million years old!

We're very happy to go out on a limb and proclaim this is a terribly silly conclusion. C'mon people: this map, while an intriguing find, was not made during the mid Cretaceous -- not unless time travelers or aliens did the work! That the map-makers used fossilized shells as markers on the map tells us nothing of the age of the map, with the possible exception of proving that the map was made sometime in the past 120 million years after the most recent fossilation had taken place. Are we supposed to believe that a person living 120 million years ago embedded a live specimen along with a 380 million year old shellfish fossil? Think, people! As Chuvyrov himself drolly explains: "The map's creator probably used a petrified find."

Let us reiterate: the map is NOT 120 million years old. If we turn out to be wrong about this, all bets about everything will be off, so we're not too worried about embarrassing ourselves on this point. Moreover, the very argument relegates an otherwise important archaeological find to the nether realm of fringe science fiction.
