Factual error: "Colonel" Roderick has incorrect rank insignia on his collar. Looks like Sergeant First Class (three above, two below).
Continuity mistake: When the boy wakes up in the middle of the night after first hearing the dinosaur, his alarm clock reads 2:0x (its not clear but the digit segments on show imply it's either 2:05 or 2:06). The next time we see the clock it's 2:02, then two scenes later when the dinosaur decides to and then does jumps off the table the clock now reads 2:22.
