If you could bring back one dinosaur, which one would it be?

Heh, just had a vision of me riding on the back of my pet Triceratops. Horny all the time just like me and easy to feed, need grass cut sure no problem I’ll just ride on by your place to have coffee and let big T graze for you. 😎 Oh yes definitely would bring back a walking tank that eats foliage.

I could see multiple reasons for bringing back triceratops dinosaurs to this time and although it seems like it would be beneficial to be in the plains to have one I could see it also be something that sounds better in a thought experiment rather then actually doing it.
