When "Jurassic Park" debuted in theaters 25 years ago, the prospect of human-made dinosaurs felt like pure science fiction. But scientists are discovering more about the prehistoric beasts almost every day.

"A new species of dinosaur is being found once a week," says paleontologist Steve Brusatte. Brusatte says we used to think of "dinosaurs as slow, brutish losers waiting around to become extinct. We now know that wasn't true."

Also ... there were feathers. New research suggests dinosaurs might have looked more like chickens than the scaly green examples from the "Jurassic Park" films.

And resurrecting dinosaurs may be closer to reality than ever before. Amidst the release of another "Jurassic Park" movie, we wonder: How far off is this new storyline from reality? And if we do have the ability to reverse extinction, should we?
