Why don't the sharpteeth talk? Would that make it too creepy?
Now granted I haven't seen ALL of the... what is it 13, 14 sequels?..... I know I saw at least the first 7, through The Stone of Cold Fire. Anyways, from what I remember the sharpteeth NEVER talked. The only exception to that was lil Chomper from the sequel when he showed up again in the 5th one. He could talk like all the other dinosaurs, but then again, he had gone vegetarian if I remember right.
So does being a carnivore infringe upon a dinosaurs ability to speak english in LBT universe? I'm kind of assuming that they don't let them talk because then that would make them slightly more humanized. As is, the sharpteeth are sort of monsters. Do you think it would scar kids if they had allowed the sharpteeth to speak english and interact with their prey?
Now that I think about it, this same rule was applied in Disney's 'Dinosaur'. All the animals could talk..... except for the meat eaters.
