We all know the movie Jurassic park. Being on an island and having limited access to weapons makes the T-Rex, for example, very dangerous.

Now let’s suppose the dinosaurs live on all continents in the 21st century (secret experiment gone awry). They sometimes kill humans, often they kill animals, including our livestock. The United Nations decide that dinosaurs need to be wiped out again.

I think killing the T-Rex will be easy using helicopters and rockets. With the right weapons these giants won’t pose a serious threat.

So which species of dinosaurs do?

Which are the most dangerous ones in such a scenario?
