** You think he's bad in the movie? He's even worse in the novel. In the movie, he's mostly portrayed as an instinctive force of nature, but in the novel he's almost portrayed as a narcissistic serial killer who fancy himself above other dinosaurs. And the novel confirms he's deliberately hunting the children for no reason but for petty revenge, and during his hunt, he toys with them just to enjoy seeing their terror before he kills them. And when he finds the entrance to the Great Valley, the novel says that he growled and sniffed the air "in evil joy", which would hint that he really mostly kills other dinosaurs just ForTheEvulz, and the next thing he plans to do after he kills the childen would be going aroung doing a killing spree in the Great Valley.

** Going further, you can see some dinosaurs running away from the fissure on slabs of rock. Watch the scene again: [[http://www.youtube.com/watch?v=lQO78ArScm8]] you can clearly see that some of them don't make it...

* [[ThoseTwoBadGuys Rinkus and Sierra]] from "Stone of Cold Fire". They start out seeming like [[IneffectualSympatheticVillain comically ineffectual villains]], but they show their true colors later on in the film as a pair of disturbingly realistic sociopaths. Sierra is easy to summarize; violent, hateful, sadistic and all too willing to [[WouldHurtAChild kill a group of small children]]. Rinkus, meanwhile, starts out seeming like a silly, DirtyCoward (being [[Creator/RobPaulsen voiced by]] [[WesternAnimation/PinkyAndTheBrain Pinky]] undoubtedly helps in that regard), but then we find out just how nasty he truly is when he plots with Sierra to use Pterano to both their advantage and, in his words, "let him lead [them] to the stone". And when Pterano proves himself to be entirely useless to them, Rinkus drops his loopy, cowardly persona, implying that said persona was fake all along...

* The pachycephalosaurs that attack Cera in the first. The fact that [[SomewhereAPaleontologistIsCrying they weren't even carnivorous]] may make it more or less scary.

* Another equally scary thing was the T.Rex. It freaking chased the heroes through half of the movie.

** It doesn't help that it's a Main/{{Expy}} of the Liopleurodon from BBC's WalkingWithDinosaurs

* The Gigantosaurus from the fifth movie has one of the most intimidating designs to date, and it friggin' tosses around other Sharpteeth. It's also the only character to shed '''[[FamilyUnfriendlyViolence blood]]''' in the entire franchise.

** The fight scene between Littlefoot's mother and Sharptooth. [[spoiler: She even dies afterward.]]

* The tar pits. Seeing all the innocent, rather young protagonists getting submerged in black gunk and nearly losing their lives is ''not'' a fun thing to watch at the age of 6 ''or'' in your adulthood. The 'tar monster' that the characters form to frighten' Cera is also pretty morbid in appearance, and definitely isn't pretty to look at, either. It looks like some sort of EldritchAbomination, honestly. Made worsedue to the horrifying noise made by the "tar monster".

* The many instances where the characters almost died horrific deaths. Keep in mind they're supposed to be really small children, even if their ages are somewhat vague.
* The Swimming Sharptooth in ''The Journey to Big Water''. Its eyes are pure yellow, and its face looks vaguely like a crocodile's skull. The worst part is that it is in the water. You won't be able to see it or hear it until it attacks, and if you're in the water, you are entirely helpless against it.
