Turns out the half-life of DNA is 521 years, so the idea of finding an insect preserved in amber that happened to have just sucked up some dinosaur blood is, well, just a Hollywood fantasy. Not that it always wasn't, but there were some scientists who were hoping.

At 521 years, half of the bonds in a strange of DNA dissolve. Another 521 years, half of what remains goes away, and so on. Even though the rate may diminish over time, the total elapsed time from "whole" to 'none" turns out to be under 7 million years. And the dinosaurs disappeared 65 million years ago.

Too bad. I was hoping they could cloe one and I could ride it, just like I saw in that Kentucky Museum of Real History.
