Is Shin-Gojira a resurrected fossil?

Hello there.

    Over the last few months, we have seen a vast plethora of new images detailing the upcoming Shin-Gojira - and I must say that I am ecstatic! Yet the most compelling thought running through my mind centers on the tip of Gojira's tail. It looks like a fossil. This bit of information causes me to think back to the original 1954 Gojira, in which it is stated that he has been resurrected by the atom bomb. Could it be that nuclear testing jump-started the few remaining bits of living DNA held within the fossilized remnants of some unknown and ancient creature? If so, is Shin-Gojira's hideous and malformed appearance the product of faulty regeneration carried-out by reawakened cells that no longer function properly as a result of nuclear restart? As always, your thoughts and conjecture are most appreciated, even if you choose to keep them to yourself. :)
