At first, Momma Dino appears to be the villain of Ice Age 3, when she kidnaps Sid to rescue her babies. However, later on, near the end, Momma Dino saves Sid and the others by knocking Rudy off a cliff. It is revealed later, though, that Rudy isn't dead.

Earlier on in the film, Sid seems to realize she's not as bad as she seems - she sleeps up in a sheltered cave with her babies, and when Sid says he will sleep on the ground, Momma Dino reaches down with her tail and puts him in the cave with the babies. Momma Dino also proves that Manny is wrong when he says "I'm the biggest thing on Earth!"

Character backgroundEdit

It's unclear how Momma and her kind got down to the secret world under the ice but over the years she and her species started to die off leaving herself and Rudy as the major predators. Towards the end of the film she and her kids go somewhere in the underground world possibly to see the Father of her kids and gives Sid a lick, as she will miss him. She is larger than largest known Tyrannosaurus found, "Sue".

Ice Age: Dawn of the DinosaursEdit

Momma Dino first appears (or rather is heard) after Sid had stolen her eggs from the ice cave, roaring in fury when she found them gone and decided to find them. The next morning Momma Dino appeared in the valley, didn't seem interested in hunting or hurting the mammals, just looking for her missing eggs. When she past a rock cave she heard a sudden cry, and turned and investigated. When she lifted the the rock roof she found her babies, and the culprit responsible for the theft. Even though Sid told Momma the babies were his kids and that she had go through him to get them, she just cocked her head with a raised eyebrow and then scooped them up in her jaws and left, with the helpless Sid screaming. When Momma arrived in Dino World she lowered her babies to ground and let them go, but not Sid, who she was going to eat. Desperately, Sid grabbed a vine while yelling, "NO! I'm too young to be eaten!" But as Momma continued to stretch Sid, the vine snapped, hurling him right into her right nostril. Momma tries hard to eat Sid, but due to his earlier raising of the baby dinos, they stood up for him. So Momma and Sid decided to see which one of them could raise the baby dinos the best. Sid wanted the babies to eat vegtables while Momma wanted them to eat meat. Momma and Sid argue about what the kids should eat. She grabs Sid and throws him in a nearby pond. Momma wins the arguement by feeding the kids a giant carcass. But, she then hesitates as she hears Rudy, Buck's archenemy, but Sid doesn't know what it is, since he doesn't know about Rudy. He and the other dino babies are taken to safety into her cave. That night Momma Dino takes her babies up to her nest, for sleep, but not Sid, who did steal her babies before. Sid tries to sound optimistic, but admits to himself quietly and softly that he misses his friends, and thinks that they aren't missing him, because of his clumsy nature and the damage he caused to Manny and Elle's kid's playground, thinking that because of this, everybody hates him. Momma Dino senses Sid's hard time, takes pity on him and takes him up to her nest where her babies are sleeping. Sid gratefully says that she's a real softie, but she doesn't seem to hear him as she looks for any signs of Rudy, before she herself nestles in for the night. That very moment, Rudy walks past the cave. The next day, the kids play with Sid, Momma hears Rudy and accidentally leaves Sid at Rudy's mercy. Momma Dino doesn't appear again, until later in the movie when she saves Sid from been eaten by Rudy and knocking him down towards an empty chasm. She then gives a roar of triumph, knowing now that she and her family can now live without fear. She and her babies say good-bye to Sid as he goes back to his regular herd.


Momma Dino has a "no nonsense" kind of attitude and does not show much humor like Sid the sloth, and has a bit of a short temper. She does not keep her feelings to herself, nor can she tell how she feels about anything because she does not comprehend the language of mammals. She normally speaks a language that is spoken by growling, roaring, and grunting. In the scene were Sid is trying to feed the Baby Dinos vegetables, Momma uses her tail to turn the stone table around so that the presumed dead caudipteryx was facing her babies. When Sid turns around and tells her that he's trying to have a conversation with her, she grabs the broccoli in her jaws and tosses Sid into a small pond, this might show she doesn't want her kids eating vegtables or doesn't like conversations. According to the Ice Age 3 commentary, Momma has an edge to her personality, but also a soft side because she is also a mother. Real fossil evidence does suggest T-Rex lived in family groups.

Relationship with SidEdit

Sid is somewhat suggested to be Momma's love interest and possible husband in the end. At the end of the movie she kissed him. However, this is subject to debate. Still, if so, then this would be the first interspecies relationship in the series (Peaches (Manny and Ellie's daughter) and Louis who are a mammoth and molehog pair in the fourth film may become the second in the series for it has been suggested that Louis, a molehog, may have a crush on her).
