Actually, the DNA code for a dinosaur, like any multicellular animal, is incredibly complex and the movie covered the fact that in that code, since it\'s so old to begin with, there would be gaps in the sequencing thus cloning the dna would be pointless since it wouldn\'t even turn into a dinosaur. In the film, they used amphibian, frog, DNA to fit in the gaps (which also explained how the dinosaurs started breeding in the first place thanks to the frog\'s ability to spontaneously change sex in a single sex environment), but I highly doubt that is entirely possible.
If they could find a way to fill in the gaps, they\'d then have to find the DNA for the different types of dinosaurs. Finding one is a miracle, finding 20, that\'s something else.
