It's a buzz word, it sounds cool, that is all.

Even Jurassic Park used it even tough most of it's creatures are from the Cretaceos, I think it was even discussed in the books, how they throught Cretaceous Park did not sound marketable.

Besides, I don't think the world of Monster Hunter is Holy Terra anyway, so geological eras would not matter much here.
