Kentrosaurus' are seen a couple of times in the film, as background features. They have unusually long necks and bulging eyes, along with a hooked beak, like that of a hawk's. This isn't the only inaccurate interpretation of a dinosaur that the Ice Age 3 creators made, though. (With a Long-neck mistake of a Plateosaurus)
- Kentrosaurus was a small member of the Stegasaurid family.
