When the father and the two kids have survived most ordeals on their way back to the base, they watch some running dinosaurs that move like flock of birds. Suddenly they change their direction and run towards the frightened family. Then we get to see them escaping running towards the camera with the dinosaurs chasing them. If you look carefully, you'll see the tracks in the grass from the van/car that has the onboard camera... Really not necessary, is it?
