Thanks a lot Science, you ruined a dream of mine.

"Let's just tear the band-aid off: all DNA deteriorates at about the same rate, and a recent study published in Nature found that rate to be a half-life of 521 years. So unless Chris Columbus was riding a plesiosaur when he "discovered" the "new world", collecting enough DNA to clone a dinosaur is pretty much completely impossible.

Even preserved in amber, it deteriorates fully in 1.5 million years. Given that the last dinosaurs went extinct 65 million years ago, bringing them back looks to be totally out of the question."
