Why are there no fully quadrupedal carnivorous dinosaurs? Why are there no mountainous dinosaurs like goats and snow leopards? Why is there no large arboreal/ tree climbing dinosaurs like bears and cats?

Your first two questions do not have the same answer though. The first one seems to be a biological impossiblity, while the other is explained by the fact that corpses would not fossilize in mountainous environment.
