In Jurassic Park, Michael Crichton's best-selling novel and the new motion picture, scientists bring to life a menagerie of dinosaurs. They clone the behemoths by retrieving dinosaur DNA from fossilized insects that fed on the dinosaurs' blood.
Farfetched? The concept of sequencing portions of dinosaur DNA could soon become a reality, according to George O. Poinar, a paleontologist at the University of California at Berkeley whose research inspired Crichton's plot. "We've got a project underway to extract dinosaur DNA from insects preserved in amber samples," he reports. Cloning the long-extinct giants, however, isn't possible yet. Still, he doesn't rule out the possibility that the technology for cloning could become available sometime in the future.

You will note that the article that you cite states plainly that no DNA has actually been found thus far.
