Re-read the article. The guy did NOT say that we can clone the mammoth. He is SPECULATING that, at some point in the future, our technology will have advanced to the point where we may be able to do so. But we can't now. And, there is a HUGE difference between recovering DNA after tens of thousands of years (mammoth), and recovering it after tens of millions of years (dinosaurs). Never say never, but I seriously doubt Jurassic Park is something to be seriously considering in the foreseeable future.
