On the scene right after the whole DNA movie, the main charactors go and look at a dinosaur egg being hatched. The egg is being held by a robotic arm. Watch closely while the camera angles change and ***Poof*** the arm dissapears!
I noticed this also, but after rewatching the scene, I have noticed that in the shot when the robotic is arm is a view from behind Jeff Goldblum (notice the blue shirt), the shot after this is a shot from behind the white bearded guy with glasses. There is nothing to suggest that these scenes follow directly after each other. Actually, a dinosaur breaking out of an egg would take longer than shown, therefore I actually believe that the multiple camera angles are a subtle attempt to suggest the passing of time. The robotic arm could retract fromt he egg in half a second, but why would they show the full 90 seconds of the Velociraptor breaking free from the egg when different short shots can be stiched together for this short scene. And after all, there is nothing to suggest that each camera shot directly follows the last. For some reason people presume this of most movies. That is like suggesting that the length of their adventure was only the length of the movie.
