History WesternAnimation / IceAge3DawnOfTheDinosaurs

** Ellie has a moment of this when her mate and friend both nearly get EatenAlive by a carnivorous plant.

* InstantBirthJustAddWater: Ellie gives birth in the middle of a Guanlong fight, screaming and wincing, and Peaches comes out already clean, happy and sleepy. One of the most exaggerated Hollywood births ever.

* AttackOfTheFiftyFootWhatever: Manny, if he's the same size as a real mammoth, is about 11 feet tall at the shoulder. Which makes Mama ''T. rex'' and Rudy around 40 to 50 feet ''tall'' (real life ''Tyrannosaurus'' was 13 feet tall at the hips, ''Baryonyx'' was 9 feet tall, and for comparison ''Spinosaurus'' was 15 feet tall). And that's not getting into the very-oversized ''Ankylosaurus'' and ''Pachycephalosaurus'', the ''Stegosaurus''-sized ''Kentrosaurus'', the ''Pteranodon''-sized ''Harpactognathus'' and ''Pterodactylus'', and the Franchise/{{Godzilla}}-proportioned ''Brachiosaurus''. Pretty much the only animals decently sized are ''Triceratops'', ''Iguanodon'', ''Guanlong'', and ''Troodon''.

* PteroSoarer: Roger the ''Harpactognathus'' (possibly). Also the flock of (oversized) ''Pterodactylus'' that attack Buck and the possums (though it's interesting to note that they're one of the few depictions to get right the fact that the genus had a soft-tissue crest).

* SeldomSeenSpecies: Probably the first theatrical film to feature ''Baryonyx'', ''Kentrosaurus'', ''Guanlong'', and ''Harpactognathus''.

* StockDinosaurs: This film has ''Tyrannosaurus'', ''Brachiosaurus'', ''Triceratops'', ''Ankylosaurus'', ''Iguanodon'', ''Pachycephalosaurus'', ''Archaeopteryx'', ''Troodon'', and ''Pterodactylus''.

* AdultFear: Manny, who witnessed the deaths of his first mate and son, is essentially waiting for the bubble to pop.

* PlotMandatedFriendshipFailure: Diego and Manny have a rift in their friendship when the former decides he's leaving the herd, which greatly offends the latter.

* PlotMandatedFriendshipFailure: Diego and Manny have a rift in their friendship after the former decides he's leaving the herd, which greatly offends the latter.

* PlotMandatedFrienshipFailure: Diego and Manny have a rift in their friendship after the former decides he's leaving the herd, which greatly offends the latter.

* RaptorAttack: Averted, for ''Guanlong'' (a primitive tyrannosaur) is used as a substitute for raptors. Played straight with the ''Troodon'', which barely look like the real animals and lack feathers, and the ''Archaeopteryx'', which has a lizard-like head and is flightless.

* AttackOfTheFiftyFootWhatever: Manny, if he's the same size as a real mammoth, is about 11 feet tall at the shoulder. Which makes Mama ''T. rex'' and Rudy around 40 to 50 feet ''tall'' (real life ''Tyrannosaurus'' was 13 feet tall at the hips, ''Baryonyx'' was 9 feet tall, and for comparison ''Spinosaurus'' was 15 feet tall). And that's not getting into the very-oversized ''Ankylosaurus'' and ''Pachycephalosaurus'', the ''Stegosaurus''-sized ''Kentrosaurus'', the flock of ''Pteranodon''-sized ''Pterodactylus'', and the Franchise/{{Godzilla}}-proportioned ''Brachiosaurus''. Pretty much the only animals decently sized are ''Triceratops'', ''Iguanodon'', ''Harpactognathus'', ''Guanlong'', and ''Troodon''.

* ThatCameOutWrong: After seeing Peaches for the first time, Buck innocently asks a pterosaur "Have you ever thought about having kids?" The pterosaur gives Buck an awkward glance, then [[ScrewThisImOutta quickly takes off]].

* ThirdIs3D
* TyrannosaurusRex: Momma and her babies are ''Tyrannosaurus''.

* NotReallyABirthScene: Ellie is giving birth while Diego fights off some ''Guanlong'' trying to kill her. At one point Diego is the one appearing to go through labor pains, and then the camera pulls back to show him pushing a pair of ''Guanlong'' off a ledge. She's telling him to push, he claims that she has no idea what he's going through, and then there's a moment of silence as he processes what he just said before sheepishly apologizing.
* OpenMouthInsertFoot: See above entry.

* RaptorAttack: Averted, for ''Guanlong'' (a primitive tyrannosaur) is used as a substitute for raptors. Played straight with the ''Troodon'', which barely look like the real animals and lack feathers.

* SeldomSeenSpecies: Rudy is probably the first ''Baryonyx'' to ever appear in a theatrical film. ''Kentrosaurus'', ''Guanlong'', and ''Harpactognathus'' also make appearances.

* TakeThat: Possibly one against ''Film/JurassicParkIII''. In the third JP, a Tyrannosaurus is killed after a brief fight with the Spinosaurus. Well, at the end of the third Ice Age, Mama (a Tyrannosaurus) turns up just at the last moment and attacks Rudy (an overgrown Baryonyx, related to Spinosaurus), effortlessly charging him, slamming him through the jungle and knocking him off a cliff. He doesn't actually die, but it was an incredible asskicking for the supposed BigBad of all dinosaurs in the series.

* VerbalTic: Listening closely to Buck reveals that the weasel is somehow prone to neglecting the usage of the letter H in his speech... ...which is probably due to Simon Pegg (his voice actor) being English.
* WhoIsDriving: CrazyAwesome Buck captures a pterosaur and commandeers it like an aircraft, along with possums Crash and Eddie, in a tow to rescue Sid. This trope plays with all three of them looking down to check on Sid as they escape; apparently, the pterosaur ''can't'' be trusted to [[FridgeLogic fly by itself]].

* GoOutWithASmile: CrossesTheLineTwice here. The way to the subterranean world goes through a crevasse full of toxic fumes, which is revealed to have very similar properties to [[Franchise/{{Batman}} Joker's laughing gas]].

* ChasedOffIntoTheSunset: Played with, the movie ends with Buck realizing his nemesis Rudy (the great white Baronyx) is still alive, [[SealedEvilInADuel and goes back to continue fighting him.]]

* EatenAlive: Little Johnny the aardvark. Thankfully, the baby T-Rex spits him out.

* ScrewThisImOuttaHere: When the Herd arrive at the hole, Crash and Eddie decide to write off Sid as dead and leave, but Ellie stops them.

* StockDinosaurs: This film has ''Tyrannosaurus'', ''Brachiosaurus'', ''Triceratops'', ''Ankylosaurus'', ''Iguanodon'', ''Pachycephalosaurus'', and ''Archaeopteryx'', but averts this with ''Kentrosaurus'', ''Guanlong'', ''Harpactognathus'', ''Troodon'' (to some extent), ''Pterodactylus'', and ''Baryonyx''.

* TyrannosaurusRex: Momma from the third movie.

-->'''Gazelle''': Eat my dust, dingo!

-->'''Manny:''' Oh, I was thinking it'd be something terrifying, like... ''Sheldon'', or [[Film/MontyPythonAndTheHolyGrail Tim]].

* NotReallyABirthScene: Ellie is giving birth while Diego fights off some raptors trying to kill her. At one point Diego is the one appearing to go through labor pains, and then the camera pulls back to show him pushing a raptor off a ledge. She's telling him to push, he claims that she has no idea what he's going through, and then there's a moment of silence as he processes what he just said before sheepishly apologizing.

* EvilAlbino: Rudy.

* DidYouDie: When Buck is telling the story of his encounter with Rudy. "Sadly yes... but I lived!"

* CleanPrettyChildbirth: The baby mammoth Peaches is born, then shown dry and fluffy within seconds after birth. Given that modern day elephants are born in an absolutely torrential downpour of blood, and it's a movie for kids, this is probably for the best.

* PteroSoarer: Roger the ''Harpactognathus'' (possibly). Also the flock of (oversized) ''Pterodactylus'' that attack Buck and the possums.

* [[ManEatingPlant Mammal-Eating Plant]]

* MidairRepair: Buck performs mouth-to-mouth on a pterosaur knocked unconscious by a mid-air collision..

* RedWireBlueWire - Hilariously spoofed in the carnivorous-plant action-sequence.

* TheVamp - Scratte. Might also count as a squirrel version of LadyInRed.

* ArgumentOfContradictions: Happens between Sid and a beaver child and its mother in Ice Age 3: Dawn of the Dinosaurs, when Sid's dinosaur-"kids" harass the other kids on the playground built by Manny.

** Although it could be possible ''Kentrosaurus'' and ''Brachiosaurus'' are actually ''Dacentrurus'' and ''Sauroposeidon''.

-->'''Eddie:''' Aw... *Hangs head, walks to the back of the pack*

* GoodLipsEvilJaws: The good Mommy dinosaur vs the Albino DinoMonster.

* MeadowRun: Spoofed when Scrat is running towards his acorn after leaving Scratte, and the acorn starts rolling down towards Scrat in slow motion while Scrat is also running in slow motion.
