Okay I'm starting to have my doubts that it might just be the full uncut version... or would that be possible? I am remembering more scenes which actually include T-rex. One scene which I'm 99,99% sure is after they wake up to the roar and Cera peeks over, the sharptooth is shown sniffing the air and moving closer.
Another one, which I'm not that certain about, is that after they get away from that small hole, the sharptooth breaks out from the rock and they run away. One thing that supports I remember correctly is that there's the same rough cut (picture halts before fading out completely) as just before the berry scene with Ducky.
