Visible crew/equipment: When Sarah and Nick return to the trailer with the baby T-rex, there is a shot of Nick carrying the rex towards the operating table. Look between the baby rex's legs - there are a series of wires leading from a opening in the anamatronic dinosaurs belly to a bulky device (presumably a battery pack) in the actor's pocket. Once you know where to look for the wires, you will notice them in many other shots in the film when various actors are holding the baby rex.

Continuity: When Jeff Goldblum is trapped in the car with the raptor outside, the raptor bumps into the window, cracking it. There's no hole in the centre of the crack in the shot of the raptor, but when we see a shot of Jeff Goldblum a second later, there's suddenly a hole in the window. Submitted by Jon Sandys

Continuity: When they're in the shack, and the raptors are making the walls shake, something like an animal's muzzle falls off the wall and lands in front of the door. We then see a closeup of the raptors starting to dig under the door, and there's no sign of the muzzle. We then cut back to a wider shot of the door, and the muzzle's back there again.
