Will it ever be possible to bring back dinosaurs?

Like most people, after watching Jurassic Park I began to wonder how possible it would be to re-grow dinosaurs. Will the technology ever exist to make it feasible, or is it strictly fiction? I only ask because Compies look like they would make awesome pets.

No. 

DNA doesn't last very long, it doesn't survive fossilization,  and it certainly doesn't survive deep time. 

Jack Horner talks about this in his book, How to Build a Dinosaur. He also did a TED talk about this which is worth watching.

The upshot: we don't have to bring them back because they're still here: they're called birds.
