I wouldn’t want to really find out.

The first and most ambitious hurdle to returning living dinosaurs to Earth is, of course, reconstructing their DNA. At current, that’s a scientific impossibility. DNA just doesn’t last that long. The oldest DNA from a fossil record is about a million years old. That’s impressive, to be sure, but it’s a long way off from the 65 million years we’d have to traverse to get to even the most recent of Cretaceous dinosaurs. Not to mention the even larger historical distances we’d need to travel in order to find the Jurassic period dinos that lend the franchise its name.
