(at 45:42) After Cephu saves George and Susan from being killed by Kiviat's men, George tells Susan to run. When it cuts back to Susan, you can see Baby running away into the forest in the dark background. In the next shot, Baby is still by the log and is just then turning to run away.
(at 1:12:35) George and Susan switch places after they jump off the waterfall in the cave.
In a wide shot at 51:45, the scientists and soldiers confront the adult dinosaur, which can been seen to already have two tranquilizer darts in its neck, moments before the order is given to use the tranquilizer gun. After the first shot, a wide shot still shows two darts.
(at 1:21:31) During the epic fight in Kiviat's camp at the end of the movie, Kenge Obe drops a Molotov Cocktail from his plane, causing one soldier to fly into the air right in front of George and Susan. Watching the shot in slow motion, one can see the small square wooden platform that is propelling the stuntman into the air.
Susan occasionally smokes on the job. A good archaeologist/anthropologist/naturalist would never do this, as the cigarette ash would contaminate the pristine environment.
