Help stuck on this level!?

Ok im past the point where the little australian weasel escaped the gas chamber, or whatever, where he has to hop up different levels of rock to escape the poisonous gas. Anyway I pass that point and the i reach a point where im on the edge of a cliff where i have to jump and catch a vine (and i do) but idk where im suppose to swing to next since there isnt another vine. I manage to land safely on a rock below. Then I'm supposed to find a dino to break down walls but I cant seem to find the dino anywhere. help plz?? where is the dino?
