I'm sure that this won't happen, but would be epic on the game's plot.

Since that weird virus can revive monsters (as shown in the past, in a gameplay versus Tigrex), maybe that huge skeleton can get "revived" in any part of the history. So you'll have to figth that massive bone dragon to keep the villages safe. Imagine that it revives when you are under it... you see the bones rising, and a huge beast starts walking, and you have to chase it and save a near village. It would be an epic battle against an Elder Dragon.

In fact... if you think about it, if that creature revives and it's muscles, organs, skin, etc. is restored, it could perfectly be that huge Jhen "Monohran" like monster they have shown time ago. So that monster can be the ancient bones when they came alive.
