According to Jack Horner, professor of palaeontology
Yes, I'm sure a professor in paleontology will now everything about the genetic problems that will arise...
To name a few: Mere DNA is not sufficient for an fertilized oocyte to develop, generally an oocyte contains maternally provided protein and RNA, where are you going to get those? Second is epigenetics: The DNA generally contains a lot of modifications to "switch on or off" genes, during embryonic development the DNA is heavily reprogrammed, those cues are probably very species specific, again where are we going to get an dinosaur oocyte??? I'm sure there are even more difficulties to overcome.
