Corrected entry: At the start of the movie, when the pig-type creatures are playing "Extinction", one of them dips his trunk in the mud. In the next shot of him, the mud has disappeared. (00:04:05)
Corrected entry: In the opening sequence, where the crack in the ice is snaking along, it goes up the cliff, then along a huge plateau, then up another cliff, which starts to fall. How did that falling cliff get to Scrat over that huge plateau so quickly?
Corrected entry: When Sid finally gets the melon from the Dodos and he's flying through the air towards the rest of his gang, the baby has his mouth wide open.

Corrected entry: At the end of the film, we see the little boy's father laying a necklace on what appears to be a makeshift grave for him, as the father thinks the little boy is dead. Why don't we see another makeshift grave for the man's wife, who really is dead? Did he forget about her? If he did make one for her, but was somewhere else, then why didn't he put the two beside each other, instead of them having separate graves?
Corrected entry: When the two glaciers hit each other and you see Scrat flying away, you see the two glaciers together are perfectly aligned with a crack going up the middle, the crack is very jagged and the sides of both the glaciers were straight before.
Corrected entry: One of the tigers says that mammoths never travel alone when in fact adult grown males always travelled alone. (00:24:30)
