This is a easy-seeing mistake, and very interesting:

1- Skip the video tape to the part of the tyranosaurus attack.

2- In one scene, the man who's in the children's jeep goes out and leaves the door opened.

3- In the next scene, into the jeep of Allan Grant and Ian Malcom, if you look at the glass you'll notice that the door is closed!!!

4- In the next scenes, the door is closed again.
