** [[AdaptationalVillainy He's even worse in the novel]]. In the movie, he's mostly portrayed as an instinctive force of nature bordering on SuperPersistentPredator, but in the novel he's more akin to a serial killer who fancies himself above other dinosaurs. He's hunting the children for petty revenge (Littlefoot and Cera in particular, as the former [[EyeScream blinded him in one eye with a thorn]] and the latter used him as a headbutting practice target while he was knocked out), 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 around doing a killing spree in the Great Valley...

** Also from "Stone of Cold Fire," a flashback shows that Pterano got into a disagreement with the other dinosaurs searching for the Great Valley and the herd split into two fractions. Pterano led his to a secluded valley, which they thought for sure was the paradise that they were looking for. [[RaptorAttack And then the raptors show up.]] While no blood is shown, the scene is still pretty violent, and we only see a brief glimpse of the massacre. The only onscreen death we ''do'' see is a swimmer falling off a steep cliff into the gorge below. Pterano was the only survivor, and that's only because he can fly.

** Sharptooth himself IS this trope. Imagine a large, extremely vicious T-Rex that simply does not give up until he kills his target, no matter how many times said target escapes. Not to mention the fact that he is extremely feared by the main charaters (can you blame them?!) and they have to live in constant fear of him. The scene where the beast ambushes them while THEY WERE ASLEEP shows that he can attack ANYWHERE.
** You think he's bad in the movie? [[AdaptationalVillainy 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 fancies 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 around doing a killing spree in the Great Valley...

** Note also that many scenes featuring Sharptooth were cut because the producers feared that they might actually cause ''psychological damage'' to children. So, scary as Sharptooth is in this film, what we get are the ''least'' frightening scenes they made with him.

* 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 helpless against it.
** It doesn't help that it's a Main/{{Expy}} of the Liopleurodon from BBC's ''Series/WalkingWithDinosaurs'', and that it boasts probably the most accurate design of any of the Land Before Time creatures.

* The Giganotosaurus 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 scene in the first film when a newborn Ducky jumps directly into the mouth of a giant snapping turtle. Thankfully, her mother manages to grab her in time, but there's some major AdultFear right there.

* The pachycephalosaurs that attack Cera in the first. The fact that [[AscendedToCarnivorism they weren't even carnivorous]] may make it more or less scary.
* Whatever the hell was in the 19-minutes that were edited out [[ExecutiveMeddling that were deemed to be]] ''[[ExecutiveMeddling even scarier]]'' than what actually remained! Not knowing what could be worse than what ended up in the finished film [[NothingIsScarier is freaky in it of itself]].
** Some of it has been shown, albeit in storyboard or script form. It shows things such as several near misses and more than one JumpScare (one of which seems to be inspired by the "Here's Johnny!" scene in The Shining). The deleted scene for the intro has Littlefoot and Cera climbing up and hiding in the hollow tree trunk and Sharptooth ripping apart with his claws jaws to flush them out. It also shows him toying with them before Littlefoot's mother arrived; when they emerged from the thorns it was between his legs, he slams his head down in front of them, they run back and he slams his tail down, then he swings his head towards them, jaws gaping and just misses them. He even tries to stomp on them. This likely indicates that the SerialKiller portrayal of him in the novel was originally supposed to be in the movie.

** Makes The Sharptooth even more scary in hindsight- this entire herd was willing to go on a rampage to kill a baby, and yet Sharptooth didn't even flinch at the idea of killing one dinosaur after another. He wasn't afraid that they'd gather together in a herd and fight him, he was that powerful- or overconfident- that he feared none of that.

* '''Sharptooth.''' A NighInvulnerable, perpetually furious, red-eyed demon of a ''Tyrannosaurus rex'' who brutally kills Littlefoot's mother and pursues Littlefoot and his friends with the singular intention of killing and eating them. One of the most terrifying villains villains to ever originate from family media.

* 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 scare 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 worse by the horrifying noise made by the "tar monster".

** 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...]]
