Continuity mistake: While at Dino Stop, Katie convinces her dad not to play it safe and to take a chance to save the world. Rick agrees and extends his left hand for the "all hands, Mitchell family on three." In the closeup we see Katie put in her right hand, but in the wide shot Katie's left hand pulls out. Also, note that in the closeup both Katie's and Aaron's positions between their parents are switched. (00:45:00)
Continuity mistake: When they go to the Dino Stop, Aaron is holding the dog in his arms. His dad walks by and suddenly the dog isn't in his arms with no indication of where the dog went. (00:25:10)
Continuity mistake: While the two robots speak with the Mitchells at the dinosaur store, one of them has some orange juice on his face which disappears between shots.
