Umm, no, but what does that change? (By the way, I think you mean paleontological digs, not archaeological digs...there's a big difference) If you're going to make some claims about Atlantis and dinosaurs, you're going to have to show the geological evidence that Atlantis really existed, that it's possible within plate tectonic theory for a whole continent to catastrophically sink (the principle of isostasy renders this impossible), and the paleontological evidence that dinosaurs inhabited it. Until you can do that, I think it's safe to say that it's a crackpot hypothesis with no real scientific merit.
