What's so great about Diplodocus? All they do is wander round eating all day like massive dinosaur Pandas...
I have a very strong emotional attatchment to that particular sauropod. It's best not to question the way my mind works.
OK then, but I think Brachiasaurus is a better sauropod, because it actually eats from trees...
But an Allosaur would be a lot better anyway, even though all of their prey is either gigantic, tiny or has massive spikes to protect it, so it might be even better to be a scavenger dinosaur...
And along comes an Tyrannosaurus Rex and eats you both.
Nuuuu, Latios the Funkasaurus Rex will protect us with his awesomeness. And then eat us himself.
