A lot has changed since Jurassic park premiered. We are still a ways from cloning dinosaurs, but as for other extinct species. It is within our grasp to be able to clone saber cats, giant ground sloths, woolly mammoths and rhinos, etc. in the need future. Their DNA is younger than that of dinosaurs so it will be easier, but geneticists will surly find a way to clone dinosaurs. I can picture it accept without all the dinosaurs getting lose and people getting eaten lol. I hope that never really happens.
