if only they could have lived to see us..

Honestly I wouldn't want them to see us. Humanity is more or less trash (pardon the strong opinion) and the few dinosaurs who survived have to face being hunted by them, caged, exploited and extinction due to destruction of their habitats and other causes.

Same would happen to the other ones if they had survived - or, if they survived, humans would have never existed in the first place. ( they only could evolve because mammals took all the niches dinos had and could evolve further due to those circumstances)

Soooo long story short, I am quite glad most of them don't have to whitness humanity. ^^'
But if both woul've coexisted, it sure would be fascinating how human cultures could've viewed and depict them.

Well.. I would have really loved to meet one, at least. And who knows, maybe with their influence, we would have turned out better

Me too, I would love to watch them, to see how they really looked, how they behaved and everything but not to interact with them.
I don't think humanity would've turned out any different just because some giant animals still existed ^^' Well, except some more destroyed human houses because a Giraffatitan fell onto them or something xD
