Here you will find the main characters of ''WesternAnimation/TheLandBeforeTime'' films, as well as minor characters of varying importance.

[[folder:The Gang of seven]]
A general list of tropes pertaining to the group of protagonists in the Land Before Time movies and TV series. They are: Littlefoot, Cera, Ducky, Petrie, Spike, Chomper, and Ruby.

[[caption-width-right:300: The main cast of the Land Before Time series]]

* AmazingTechnicolorWildLife
* BigDamnHeroes:
--> '''Littlefoot''': "You came for me!"
-->'''Cera''': "[[TrueCompanions Don't we always?]]"
* BrotherSisterTeam: Ducky and Spike
* CallARabbitASmeerp: The kids are, respectively, a 'Longneck', a 'Threehorn', a 'Flier', a 'Swimmer', a 'Spiketail', a 'Sharptooth', and a 'Fast Runner'.
* EstablishingCharacterMoment:
** A newly hatched Cera headbutts her way out of her egg.
** Ducky jumps around while she's barely out of the egg, follows an insect around, then [[CuriosityKilledTheCast peers curiously]] into [[FearlessFool the mouth of a snapping turtle]].
** Petrie falls screaming from a tree, gets tossed around a bit, then excitedly asks if he flew.
** Spike [[BigEater eats his own nest]].
* FightingTheLancer: Littlefoot and Cera's fight in the first film.
* FireForgedFriends
* FiveManBand: Formerly this, but gained two members in the TV show.
* GriefSong: 'Always There' (the final verse of which Littlefoot sings about [[spoiler:his mother]]) from the fifth film is part grief song and part lullaby; along with 'Bestest Friends' from the tenth movie and 'If We Hold On Together' from the first movie, it's one of the best songs the long and musical series has ever produced.
* GroupHug: At several points, but most notably in the last shot of the first film.
* HeadbuttingHeroes: Littlefoot and Cera avert this in the usual sense (except in the first movie, where it's played straight, and very briefly in film five), but the trope holds true in the literal sense: at several points they've actually butted heads.
* [[VillainRecruitmentSong Hero Recruitment Song]]: 'You're One of Us Now' from the second film. Definitely a CrowningMomentOfHeartWarming.
* InterspeciesFriendship
* [[KidHero Kid Heroes]]: It's no question that all seven of them fit, but in terms of ages, it's never definitively stated. Ruby is assumed to be the eldest of the gang, while Cera claims to be the oldest of the original five. The order of Littlefoot's, Petrie's, and Ducky's births seems unclear. The only order that is definitely known is that Chomper is the youngest and Spike is the second youngest.
* LikeBrotherAndSister: Both Littlefoot and Ruby act like older siblings to Chomper.
* MasculineGirlFeminineBoy: Littlefoot is soft spoken and polite. Cera is snarky and brash.
* NaughtyIsGood: Rarely obey their parents' rules. Then again, [[AdultsAreUseless considering not one of their parents rules has ever shown to help with anything]], you can't exactly blame them.
* {{Nice Job Breaking It Hero}}es: Many of their adventures involves one or all of them screwing up in some way, and then rushing to fix their mistake.
* OddFriendship: A soft spoken Apatosaurus, a hot headed Triceratops, a happy-go lucky Hadrosaur, a panicky Pteranodon, and a mute Stegosaurus somehow make a cohesive and tight-nit group. It gets even more bizarre when a friendly Tyrannosaurus and a whimsical Oviraptor get added to the crew.
* PragmaticHero: All of them; they're not adverse to fighting dirty when confronted with sharpteeth.
* PromotedToParent: In the first sequel, the gang ends up having to raise the newly hatched Chomper until his real parents come to claim him.
* RagTagBunchOfMisfits
* TrueCompanions
* UnusualAnimalAlliance
* VitriolicBestBuds: Littlefoot and Cera.
* WhenImGoneSong: Inverted with 'Bestest Friends' from the tenth film (which is more of a ''[='=]When You're Gone[='=] Song'' considering the context).


[[folder:''The Land Before Time'' (first film)]]
!!Littlefoot - ''Apatosaurus''
[[caption-width-right:236:"We did it! We did it together!"]]
A young male Apatosaurus born in the desolate lands east of the Great Valley. He's the main protagonist of the Land Before Time series. He lives in the Great Valley with his Grandparents and best friends.
Appears in all thirteen films and the TV series.

* {{Badass}}: Dude once threw himself off a cliff to save Chomper without a second's hesitation. Now that's hardcore.
* BerserkButton: Don't insult his mother.
* BewareTheNiceOnes: Qualifies as this in the first movie. After dealing with Cera's attitude for a while and then her remark about his mother being stupid, Littlefoot snaps at her to take it back, resulting in a fight.
* BigBrotherInstinct: Towards Chomper and Ducky.
* DeathGlare: Gives this to Cera in "The Great Day of the Flyers" when she seemed reluctant in rescuing Guido from the Mysterious Beyond.
* DisappearedDad: Played straight until The Land Before Time X: The Great Longneck Migration.
* TheHeart: Along with Ducky.
* TheHero
* HerosJourney: At the beginning of the first movie, Littlefoot is a friendless, nave child who's very much dependent on his mother to survive. By the end, he's become a strong, wise leader with more friends than he could have ever dreamed of.
* HeroicBSOD: After his mother dies, Littlefoot goes into a deeply depressed state. He refuses food when it's offered to him and seems to lose much of his will to find the Great Valley. The two things that snap him out of it is a chance encounter with the wise Rooter and running into another lost child like himself: Ducky.
* HowDareYouDieOnMe: While talking with Rooter, Littlefoot tearfully says his mother should have known better than to fight the black sharptooth. This is likely just a statement out of intense grief, as her death leaves him completely alone in the world.
* ItsPersonal[=/=][[YouKilledMyFather You Killed My Mother]]: Not outright stated, but when the opportunity to kill Sharptooth appears, Littlefoot is the first to take it.
** Less so in the original ending - where he discovered the Great Valley and then went back to rescue the others - where it was more to prevent Sharptooth from following them into the Great Valley.
* TheLeader: Classic Type II leadership.
* NervesOfSteel: If something's going wrong, Littlefoot's generally the one who keeps his head together.
* NiceGuy
* [[OnlySaneMan Only Sane Dinosaur]]: Usually. He does his fair share of unreasonable things as well.
* RaisedByGrandparents
* RedIsHeroic: His eyes are a shade of reddish brown that varies anywhere from mahogany to maroon between movies.
* ScrewTheRulesImDoingWhatsRight: Frequently breaks the rules in order to fix a problem that the adults won't.
* SiblingsWanted:
** In the 9th film, Littlefoot laments that he has no brothers or sisters to play with. One movie later, he get's an adopted brother: Shorty.
** Chomper might technically be called his 'godbrother', considering he oversaw his birth.
** Mo and Littlefoot declare themselves [[BloodBrothers 'Mud Brothers']].
* StreetUrchin: The dour conditions of Littlefoot's first years of life are a clear metaphor for being born into poverty, and when he loses his mother, he perfectly fits the description of a desperate street orphan.
* RedOniBlueOni: The calm, reasonable Blue to the hot-headed Cera's Red.
* SympathyForTheDevil: Given what the original sharptooth did to him, his friends, and his family, Littlefoot has plenty of reasons to fear and hate the newly hatched Chomper for what he is. However, he refuses to forsake a newborn child for what the rest of his kind has done, and is the most vocal proponent in the group to caring after him.
* TrademarkFavoriteFood: [[MemeticMutation Mutha fuckin' treestars, bitch!]]
* UndyingLoyalty
* WhatTheHellHero: In ''Invasion of the Tinysauruses'', Littlefoot accidentally knocks all of the fruit off of a special tree that no one is to eat from until everyone is there to share it. He proceeds to lay the blame on the innocent Tinysauruses, and the rest of the Valley inhabitants try to chase away and destroy the innocent micro-dinos. When Littlefoot admits he lied, ''everyone'' gives him a disbelieving reaction.
* WiseBeyondTheirYears: Played fairly realistically. While he's still clearly a kid at heart and prone to making mistakes, his values, beliefs, and sense of duty are very advanced for his age.
* WouldHitAGirl: To be fair, the girl in question ''can'' shatter rocks with her ''head''.
* YouImaginedIt: No one believes Littlefoot saw a mysterious blue stone fly over the Valley and land on Three Horn Peak in ''The Stone of Cold Fire''. Except for two small dinosaurs that may or not be aliens in disguise.

!!Cera - ''Triceratops''
[[caption-width-right:350:"Threehorns never play with Longnecks!"]]
A hot-headed female Triceratops. She's one of the main characters throughout the series. She lives in the Great Valley with her father, stepmother, and half sister.
Appears in all thirteen films and the TV series.

* ActionGirl: When you can shatter rocks with your head, you've earned this title.
* BigSisterInstinct: Towards her baby sister Tricia, as well as her friends.
* BreakTheHaughty: She spends most of the first film bragging about how she can take care of herself...until she nearly gets everyone killed following her way.
* CantLiveWithThemCantLiveWithoutThem: Despite constantly complaining about them, she seems to genuinely value her friends.
* CatchPhrase: In the TV series: "I'll believe it when I see it."
* DaddysGirl: She is close to her father, which makes sense because of her mother's disappearance. Her relationship with him is part of the reason why she's so stubborn and tomboyish.
* DeadpanSnarker: A big one in the sequels and TV show. Provides a lot of the funnier lines in the series as a result.
* FantasticRacism: Especially in the first film. [[DefrostingIceQueen She mellows pretty fast, though.]]
* GreenEyedMonster: Cera seems to get extremely jealous when an outside character hogs all of Littlefoot's attention. This is most visible with Ali and Mo.
* HairTriggerTemper: It doesn't take much to anger Cera. But this is toned down greatly in the sequels... [[BerserkButton unless her friends or her baby sister are being threatened.]]
* IneffectualLoner: In the first movie, before learning ThePowerOfFriendship and becoming part of the group. In later movies she still has a tendency to storm off by herself after disagreements with the group, but her leave is never permanent.
* JerkWithAHeartOfGold: She's bossy, she's egotistical, she's short-tempered, and she'll always come through for her friends. Although in the first film she was bordering on JerkAss.
* TheLancer
* RedOniBlueOni: The Red to Littlefoot's Blue.
* TokenEvilTeammate: In the first film. In some ways, she is actually ''more'' antagonistic than Sharptooth!
* TomboyAndGirlyGirl: Tomboy to Ducky (and later Ruby's) Girly Girl.
* {{Tsundere}}
* [[UngratefulBastard Ungrateful Bitch]]: For most of the first movie, she remains prejudiced against longnecks and goes so far as to call Littlefoot's mother ''stupid'' even after she'd given her life to save her and Littlefoot from Sharptooth. Like many other negative traits, this too fades out as time goes.
* UseYourHead: She is a Triceratops, after all.
* WelcomeBackTraitor: She's accepted as a friend after she helps to kill Sharptooth, even though she'd left Ducky, Petrie, and Spike to nearly die awhile back.
** Then again, Littlefoot was almost as bad, seeing as he used Ducky as bait for the Sharptooth.
* [[WhyDidItHaveToBeSnakes Why Did It Have To Be Heights]]: Cera doesn't do too well when it comes to cliffs, chasms, and anything involving crossing them. Unfortunately, they face this dilemma at least once a movie

!!Ducky - ''Parasaurolophus or Saurolophus''
[[caption-width-right:350:"Yep yep yep!"]]
A cheerful female hadrosaur. She's one of the main characters throughout the series. She lives in the Great Valley with her mother and siblings.

Appears in all thirteen films and the TV series.

* CatchPhrase: "Yep yep yep!"
* CheerfulChild
* TheChick
* DamselInDistress: Frequently fits this role.
* DisappearedDad: Her father appears in the first installment but vanishes in the sequels. Granted, this ''might'' be due to what happened to [[RealitySubtext Judith Barsi at the hands of her father...]]
* [[TreeCover Fly On The Wall]]: Her smalls size means she often walks in on important conversations unnoticed. See SpannerInTheWorks.
* TheHeart: Along with Littlefoot.
* JerkassFacade: In movie eight, Ducky attempts to pretend that she doesn't care about Spike when he starts giving his new friend Tippy more attention than her. In one scene, where Petrie casually mentions Tippy's herd is going away, the facade instantly breaks and she joyfully hugs [[CrowningMomentOfFunny a very confused looking Petrie.]]
* [[NotSoInnocentWhistle Nervous Humming]]: While trying to muster up the nerve to call Sharptooth's attention to her, she hums nervously under her breath.
* NiceGirl
* MotorMouth: A mild example in the first movie, mostly due to her many verbal tics and outgoing personality, which goes along with the original name for 'swimmer': Bigmouth.
* PlatonicLifePartners: With Petrie
* SpannerInTheWorks: It's quite amazing how such a little girl can cause so many problems for so many different villains. It's also the primary cause for her DamselInDistress role.
* TeamMom: She always comforts and pep-talks everyone, and her plucky personality usually rubs off on everyone around her.
* TinMan: In ''The Big Freeze'', Ducky had to ask Cera what the strange emotions she was feeling towards Spike's constant snoring and keeping her awake were. When Cera told her she was feeling angry, Ducky was mystified, because she had never felt anger before, and Cera has to teach her (In song, no less), how to express anger.
** This is probably referring to explicit anger, as she's clearly shown to display annoyance and dislike before this.
* TomboyAndGirlyGirl: Girly Girl to Cera's Tomboy, although she's pretty adventurous and is only really a Girly Girl when compared to Cera.
* VerbalTic: Ducky has several. The first and most widely known is her tendency to repeat yes or no three times at the end of a sentence for emphatic effect. She does the same for 'he/she/it does' and 'he/she/it is', except she only repeats these phrases twice at the end of a sentence. Finally, she'll occasionally add needless tense modifiers at the end of words, resulting in phrases like 'scardeded' and 'foundeded'.
* [[WhatTheHellHero What The Hell, Nice Girl?]]: The TV episode "Search for the Sky Colored Stones" shows that Ducky isn't without a dark side. During a hunt for sky colored stones (geodes), her brother gets stuck in a cave opening, and instead of running off to get help she proceeds to find and hoard all the geodes in the cave for herself, intentionally misdirects Ruby and Cera so they never find any themselves, and generally acts like a sneaky, paranoid nutcase.
* WhyAreYouLookingAtMeLikeThat: When Littlefoot explains his trap for Sharptooth, he realizes that they'll need bait to lure him into position. Cue a smiling head turn towards Ducky, the only one in the group who doesn't have a job yet. Naturally, she doesn't seem particularly thrilled, but seems to agree to it in the end.
** To give this context, it was a far safer job for her to do than it would been for the other three, given she just needed to lead the BigBad to a pool of water that she could swim in and he couldn't.

!!Petrie - ''Pteranodon''
[[caption-width-right:300:"You've got a nice flat head, Flat Head."]]
A panic-prone male pterosaur. He's one of the main characters throughout the series. He lives in the Great Valley with his mother and siblings.
Appears in all thirteen films and the TV series.

* ADayInTheLimelight: He is the main character of "The Great Day of the Flyers".
* [[AcrophobicBird Acrophobic Pterosaur]]: Grows out of it by the end of the first movie, for the most part.
* {{Cloudcuckoolander}}: Has a pretty vivid imagination.
* CowardlyLion
* [[CrouchingMoronHiddenBadass Crouching Coward, Hidden Hero]]: Typically overcomes his fears during life-or-death situations, only to immediately react in horror afterwards that he ever did something so dangerous.
* DidYouJustFlipOffCthulhu: When Petrie finally learns to fly, he celebrates by throwing rocks and laughing at the murderous sharptooth at the bottom of the ravine. [[spoiler: This cockiness very nearly ends in tragedy when the sharptooth tries to pull him down with him.]]
* DisappearedDad: His father is never seen, and we only ever see his mother and his many, [[AmazingTechnicolorWildlife multicolored]] siblings. Heck, unlike Cera and Ducky's unseen parents, he's not even seen in the original!
** In [[HilariousInHindsight hindsight]] this actually makes sense; recent evidence suggests that male ''Pteranodon'' had little to no involvement with the raising of their young. Of course, [[ScienceMarchesOn neither did the females]] but it still justifies the scenario a bit.
* [[spoiler: DisneyDeath: He nearly dies when they kill Sharptooth, but he ends up ok.]]
* FantasticSlur: When Petrie first meets him, he refers to Littlefoot as a 'flathead'. Given Littlefoot's reaction to this term, Petrie's lack of racist tendencies, and the fact that Petrie stops using this term soon after it's introduced, he may have unknowingly been using a racial slur that he innocently picked up from somewhere else.
* HeroWorshipper: Idolizes his uncle and takes everything he says as absolute fact. Unfortunately, [[EvilUncle his uncle isn't the best of role models]].
* PlatonicLifePartners: With Ducky
* PluckyComicRelief: The official website refers to him as "the clown of the group".
* PteroSoarer: The original movie averted this slightly as while he was still outdated by modern standards the animators gave him features in accordance to then new theories like walking on all four. Unfortunately, the sequels throws all of those features into the trash bin.
* TheSmartGuy: Though not so much because he's the most intelligent as he is the most cautious.
* ThirdPersonPerson
* [[ToothyBird Toothy Pterosaur]]: While some pterosaurs ''do'' have teeth, ''Pteranodon'' (Toothless Wing) aren't among them.
* VegetarianCarnivore: Petrie is a Pteranodon, which are known to dine on fish. Yet, he and other "fliers" are shown eating plants and there's no explanation as to why.

!!Spike - ''Stegosaurus''
[[caption-width-right:300: [[InnerMonologue 'Nothing like a treestar to start the day right.']]]]
A quiet, ravenous male stegosaurus, and the adopted brother of Ducky. He's one of the main characters through out the series. He lives in the Great Valley with his adopted family.
Appears in all thirteen films and the TV series.

* BigBrotherInstinct: Towards Ducky (even though he's technically the younger of the two).
* BigEater
* TheBigGuy
* GentleGiant
* GodGuise: In the TV episode "Stranger From the Mysterious Above", a colony of horned gophers thought he was "The Big Wise One" from their religion.
* HappilyAdopted: By Ducky's family.
* InnerMonologue: Through out most of the TV episode 'Through the Eyes of a Spiketail', we see the world through Spike's perspective and become privy to more details about his personality through his thoughts and feelings.
* ObliviousAdoption: Deals with issues related to this trope in ''The Big Freeze''.
* PlotRelevantAgeUp: He is born in the middle of the film while the rest of the gang have grown up to be kids, but grows to their age in a matter of seconds.
* PurpleEyes: During 'Through the Eyes of A Spiketail', a POV shot is given from his point of view, where everything he sees takes on a purple tint.
* ReluctantHero: He apparently isn't enthusiastic about his friend's frequent adventures outside the Great Valley, and wishes his friends could be more content with staying home and eating.
* {{Scatting}}: Keeping in line with his muteness, he scat sings during musical numbers.
* SmarterThanYouLook: In one of the TV episodes, Spike's thoughts are revealed. He's actually quite observant, and secretly rolls his eyes whenever Littlefoot and Cera get into a pointless argument.
* TastesLikePurple: He can apparently "hear" songs from plants, and can even identify them based on their different tune. Given his unusually good smelling abilities shown through out the series, it's possible that Spike is demonstrating an olfactory form of synesthesia.
* TheVoiceless: Except for ''two'' instances where he yells Ducky's name when she's in danger, and when he yells "Mama!" as he nearly drowns in a lake.
** Later revealed that he can talk but simply chooses not to.
** And, when he does "speak", it's usually [[TheUnintelligible unintelligible mumbling]]. Interestingly enough, in one episode of the series, it's shown that his thoughts are quite sophisticated.
** In several of the songs, however, he can be clearly seen and heard humming and hilariously enough, scat-singing at a few points.

!!Sharptooth - ''TyrannosaurusRex''
A vicious, relentless Tyrannosaurus who acts as the primary antagonist of the first film. He's responsible for the death of Littlefoot's mother. [[spoiler: He's supposedly killed by Littlefoot and his friends after they drop a rock on him, knocking him into a deep water hole.]]

Appears only in the first film.

* AxCrazy: Is noticeably unhinged and needlessly violent even for a tyrannosaurus.
* {{Badass}}: Being a TyrannosaurusRex helps, but even for a T-rex, he seems superhuman.
** HandicappedBadass: The novelization reveals he was blinded in his right eye when Littlefoot accidentally [[EyeScream stabbed it with a thorn]].
* TheBerserker: His face is always locked in one single expression; pure, unadulterated, pissed-off rage.
** At one point, Mama Longneck smacks Sharptooth with her tail and he smashes into a rock. He responded by ''pulverizing the rock with repeated headbutts before he does anything else.''
* BigBad: Considered this in the first film.
* CarnivoreConfusion: He is a ''T. rex'' hunting sentient baby dinosaurs.
* TheDreaded: When even baby dinosaurs know your name, you're this.
** Also, when Littlefoot's mother intervenes, she orders Littlefoot to run. This is notable because baby animals usually stay near their parents during such instances (such as Wildebeest and Bison), and the chances that Littlefoot could run into another hazard without her presence. It also indicates Littlefoot's mother knew she would likely loose the fight, and that no other hazard in the area was as dangerous as Sharptooth.
* DisneyVillainDeath: [[spoiler: Falls off a cliff into a lake and drowns. However, unlike most, his is an intentional one on the part of the heroes, though given the situation, it's hard to blame them.]]
* EatenAlive: [[FridgeHorror Possibly what he was doing to Littlefoot's mother during the fight]].
* EyeScream: Littlefoot accidentally stabs him in the eye with a thorn while trying to escape, blinding him in that eye.
* ForTheEvulz: Unlike most predators, he seems to kill other dinosaurs entirely because he ''wants'' to, not because he ''needs'' to.
* HateSink: When he kills Littlefoot's mother, it's very hard not to hate his guts.
* {{Hero Killer}}: Mortally wounds Littlefoot's mother, who, granted, puts up one heck of a fight, and almost kills the main group several times.
* ImplacableMan: One of the most notable in western animation. Borders on slasher villain territory.
* [[spoiler: KillItWithWater: Meets his end when the heroes use a rock to topple him into a lake. Due to having stubby arms, he can't swim and drowns.]]
* ItsPersonal: He hates Littlefoot because he accidentally blinded him on one of his eyes. Its heavily implied that THIS and his hatred are the reasons why he is going to such extremes to kill dinosaurs that would be of little food to him.
* KnightOfCerebus: Oh yes. The movie was very soft until he showed up. He is arguably the only villain who was treated seriously in the series.
* MadeOfIron: His stamina and strength were ridiculous enough, but he survived falling into a deep trench without any actual injury and can smash large rocks with his head with no pain involved.
* NonMaliciousMonster: Definitely averted; one of the things that made Sharptooth so incredibly terrifying was that he didn't just kill for food, he also killed for ''pleasure'' and more often, because he was ticked off.
* NotQuiteDead: Is seemingly killed when he falls off a cliff fighting Little Foot's mother. Cera finds out later on he survived and is ''ticked off!''
* RoaringRampageOfRevenge: In the novel version because while Littlefoot fled from him he sent a thorn flying into one of his eyes, half-blinding him.
** In most scenes he has his right eye closed, which supports this.
* SerialKiller: TheOtherWiki had him listed among "Fictional Serial Killers". Make of that what you will...
* SuperPersistentPredator: Is dead set on killing the group. Justifed as only a few other dinosaurs are seen during the film, so they may just be the only thing to eat. Also see RoaringRampageOfRevenge.
* TakingYouWithMe: Bites down on Petrie's tail as he falls into the water.
* TheVoiceless: Like almost every sharptooth in the series.
* UnstoppableRage: He's in a psychotic fury for every moment of screen time. And it is ''terrifying'''.
* WouldHurtAChild: Most definitely, as he literally spends his entire onscreen time trying to kill the five main characters, who happen to be baby dinosaurs.

!!Mama Longneck - ''Apatosaurus''
[[caption-width-right:348: "Dear, sweet, Littlefoot, do you remember the way to the Great Valley?"]]
A wise, maternal Apatosaurus who deeply loved her only son, Littlefoot, and hoped to lead him to the Great Valley where he could grow up in safety. She dies midway through the first film from injuries sustained by Sharptooth. Bron was her husband.

Appears only in the first film.

* AlmostDeadGuy
* {{Badass}}: She fights off a Tyrannosaurus Rex. You can't get more badass than that. She doesn't fight off the sissy Rexes that you see getting stomped on by the Great Valley adults throughout the rest of the movies. She fights ''the original Sharptooth,'' who is NightmareFuel in the form of a carnivore and capable of ''leaping onto her back.''
* FamilyUnfriendlyDeath: We never actually see what injuries lead to her death, and considering one of the scenes contains a [[ShadowDiscretionShot horrifying shadow shot]] of Sharptooth biting a chunk of flesh out of her back, it's probably better that we don't.
** What's more, there actually was film footage made depicting more of the the fight between her and sharptooth. Considering Don Bluth had this footage '''burned''', it's safe to say that her death was decidedly non-PG. Going by the footage of the shadow, Sharptooth wasn't just biting chunks of flesh from her back, [[EatenAlive he was eating them]]!

* HeroicSacrifice
* MamaBear: Oh yes. She protects her son by fighting off a bloodthirsty Sharptooth ''while an earthquake is tearing apart the land around her''.
* SacrificialLion

!!Grandma and Grandpa Longneck - ''Apatosaurus''
Two elderly Apatosaurus who helped Mama Longneck raise Littlefoot since he first hatched. When she dies, they take to raising him in the Great Valley. Believed to be the mother and father of Mama Longneck. They live in the Great Valley with their grandson.

Appears in all thirteen films and the TV series.

* AdultsAreUseless: Averted. They are the most level headed, intelligent characters in the entire series, the only reason they aren't a bigger help is that they have to deal with the rest of the adults.
* {{Badass Grandpa}}rents: Grandpa can keep up with Doc when it comes to fighting Sharpteeth. And in a battle in a later film, he and Grandma team up to [[CurbStompBattle beat a sharptooth into the ground.]]
* BigDamnHeroes: Once in a while.
* CoolOldGuy: Grandpa Longneck can hold his own against a Sharptooth. Not bad for an old dinosaur.
* CoolOldLady: Grandma Longneck has been shown to do the same twice!
* HappilyMarried: They're very kind and loving to each other.
* ParentalSubstitute: They've acted as Littlefoot's parents since the first film.

!!Topps / Topsy / Mr. Three Horn - ''Triceratops''
[[caption-width-right:210:"Come Cera, three horns never play with long necks."]]
An aggressive male Triceratops with deep seated prejudice against dinosaurs other than his own kind. He's Cera and Tricia's father, and Tria's husband. He lives in the Great Valley with the rest of his family.

Appears in every film except the fourth, appears in the TV series.

* BerserkButton: Lay a claw or horn on his loved ones -- and you'll see ''why'' he can be incredibly dangerous!
* DividedWeFall: His stubbornness finally gets him and Cera into trouble in ''Time Of Great Giving'', and they end up getting saved by Grandpa Longneck.
* FantasticRacism: Prejudiced against longnecks. Seems to get along with Grandpa Longneck in the sequels well enough, however.
* FreudianExcuse: The reason why he acts like a grump is for the sake of his family and because his own father was as grumpy as him. [[FridgeHorror The absence of his wife and all of his children besides Cera from the second film onward may also explain it]].
* GrumpyBear: Perpetually.
* JerkAss: Is the one who taught Cera her FantasticRacism in the first film, and he repeatedly causes trouble for all the other grown-ups in the sequels and the series.
** JerkWithAHeartOfGold: He genuinely loves his daughter despite all his other flaws.
* OppositesAttract: It might be hard to believe, but a guy as hard as stone eventually falls for a woman as sweet as sugar. In addition, she's the only one who can calm him down.
* [[PapaWolf Papa Triceratops]]
* [[VillainSong Antagonist Song]]: 'I'm Tough' could be considered this in the third film, given what he was doing at the time.
* WellIntentionedExtremist: He will do anything to protect his family, going to violent lengths.

!!Rooter - ''Scolosaurus''
[[caption-width-right:300:"It's nobody's fault. The great circle of life has begun. But see, not all of us arrive together at the end."]]
A wise, mysterious wanderer among the wastes of the mysterious beyond. His whereabouts are unknown.

Appears only in the first film.

* {{Callback}}: Possibly one in movie ten. Bron tells Littlefoot that he learned of his mother's death from a passing dinosaur not long after the Great Earthshake, and that this dinosaur also mentioned that Littlefoot survived. Given the timing, this dinosaur was likely Rooter.
* DoNotGoGentle: Rooter's biggest impact in the series is helping soften the blow of Mama Longneck's death-- both for Littlefoot and the younger audience-- by confirming to Littlefoot that his mother will always be with him, and that the pain he feels right now will lessen in time.
* JerkWithAHeartOfGold: When he first runs into the crying Littlefoot, he treats him with gruff indifference. When he realizes the boy has just lost his mother, he immediately softens.
* TheObiWan

!!Mama Swimmer - ''Parasaurolophus or Saurolophus''
Ducky and Spike's mom.

* ADayInTheLimelight: Got some more attention in "The Big Freeze".
* GoodParents: All too happy to adopt Spike and is very loving to all of her kids (and there's like thirteen of them!)
* MamaBear: Won't stand for any harm coming to her kids. Seriously, this mother dives ''under ice and risks her life'' to save Spike.
* PinkGirlBlueBoy: She and her husband have this color scheme in the finale of the first film. She's given a more realistic green color from the second film onward.

!!Mama Flyer - ''Pteranodon''
Petrie's mother.

* ADayInTheLimelight: Has a bit more focus in "Stone of Cold Fire" and then in "Great Day of the Flyers".
* DeadpanSnarker: Has her moments.
* GoodParents: Especially noticeable in "Stone of Cold Fire", where she makes sure to set a better example for her children than Pterano.
* MamaBear: Notice a pattern here? She flew through what was essentially a ''hurricane'' to find her missing son!
* SiblingRivalry: Played with; she's set up to have something like this with Pterano, but she has enough faith in him to know that he won't let any harm come to Ducky. She still doesn't think too highly of him, though...


[[folder:The sequel films]]
!!Chomper - ''TyrannosaurusRex''
[[caption-width-right:300:"Yep, it's me!"]]
A friendly young Tyrannosaurus who was hatched as an egg by Littlefoot and his friends. He later teaches himself the herbivore language, and becomes a speaking character by the fifth film. He and Ruby have been allowed to live in the Secret Caverns to keep safe from Red Claw, making him the only sharptooth living in the Great Valley. He becomes a main character in the TV series.

Appears in films two and five, and every episode of the TV series.

* BreakOutCharacter: Definitely the most popular character introduced outside of the original film.
* CarnivoreConfusion: Actually addressed. Normal Sharptooth would try to eat the group, but he resolves to only eat bugs in order to stay around his friends, though [[{{Squick}} they do find this disturbing as well]].
* {{Cloudcuckoolander}}: Sometimes. He tends to forget that his friends are leaf-eaters and offers them insects to eat. He also tends to be naive. Lampshaded by his parents in the fifth movie.
* CompensatingForSomething: On more than one occasion, he's shown to be very sensitive about being called 'little'.
* [[AdorablyPrecociousChild Cute Shotaro Tyrannosaur]]: Especially evident in the TV series.
* DeclarationOfProtection: He and Ducky get trapped on a rock out crop in the middle of a ravine. With a ''Utahraptor''. He assures Ducky that he'll protect her while openly declaring to the raptor that he will fight him if he tries to hurt her.
* [[ManBitesMan Dino Bites Dino]]: Chomper [[IncrediblyLamePun chomps]] down on Cera's tail (by instinct) in the second movie and an ''Giganotosaurus''[='=]s tail (to protect his friends) in the fifth movie.
* DoubleEntendre: He just ''loves'' having friends for dinner...
* EnfantTerrible: Averted, despite being an infant Sharptooth, he's a very nice guy. However he is often mistaken for this by dinosaurs that don't know him. In fact in one episode of the TV series spinoff, it almost gets him killed.
* GuestStarPartyMember --> [[SixthRanger Permanant Party Member]]
* IAmWhatIAm: Says this word for word in the fifth movie, pointing out that nobody has any control over what they're born as, and that people of very different races can still be close friends.
* IJustWantToHaveFriends: He seems to have been very lonely on his island before his old friends stumbled upon it. He's less like this in the TV show, but he does seem still seem vulnerable to feeling like the odd one out.
* MySpeciesDothProtestTooMuch: His parents are the only Sharptooth he actually seems to like, otherwise he actually prefers to hang with the Great Valley dinos over his own kind. Probably because other adult Sharptooth seem to attack him on sight as well.
* NiceGuy: In spite of being a ''T. rex''.
* {{Omniglot}}: He's the only known Sharptooth to be able to speak Sharptooth and plant eater. This comes in handy at times. Most dinosaur adults seem suitably suprised upon learning of this.
* [[RaisedByWolves Raised By Herbivores]]: Even though it was only for the first few days of his life, it's had a considerable impact on him.
* RedEyesTakeWarning: Averted; Chomper has very red eyes, yet he's a good and kind person. People who don't know him, however, tend to take the trope to heart as soon as they see him.
* RidiculouslyCuteCritter: In every appearance, but most obviously in the first one.
* SixthRanger (in animated series)
* SpotlightStealingSquad: Anyone who doesn't consider him an EnsembleDarkhorse thinks of him as this in the animated series. Of all the characters, he has the most number of episodes focused around him.
* UndyingLoyalty
* VegetarianCarnivore: Played with, as he occasionally samples "green food" in an effort to fit in, but finds it disgusting.

!!Chomper's parents - ''TyrannosaurusRex''
[[caption-width-right:335:Mama Bear and Papa Wolf taken to deadly extremes.]]
A pair of large Tyrannosaurus' who are fiercely protective of their only son. They act as secondary antagonists in most of both of their film appearances. Their current whereabouts are unknown, but they live away from their son, who lives in the Great Valley.

Appears in films two and five.

* BadAss: Well, they ''are'' T. rexes. After being initially injured by the Plated Sharptooth, Papa Rex stands up and ends the fight with one decisive blow of his tail. It also took a group of at least four adult leaf eaters to chase them off.
** BadassAdorable: And they're downright ''adorable'' when they're with their son.
* BattleCouple
* DeadpanSnarker: Chomper's father. "Sometimes I worry about that boy."
* GoodParents
* HappilyMarried
* HeelFaceTurn: Well sort of. It is revealed that they are not entirely villainous in ''The Mysterous Island'' but are still a danger to the heroes anytime they see them, until Littlefoot risks his life to save Chomper's. After that, they're much more friendly, with Chomper's mother managing to not complain (and smiling) as Cera hugs her leg.
* MadeOfIron: Much like all sharpteeth, nothing seems to be able to put them down.
* MamaBear[=/=]PapaWolf: They're very quick to come to their son's aid if he's in danger. Also part the reason they sent Chomper to the Great Valley in the series, to protect him from Red Claw.
* MonsterIsAMommy: They leave the Great Valley as soon as they find their son.
* OpenMindedParent: Mama Sharptooth gives a rather deliberate sounding DoubleEntendre when she finds Chomper hanging around with Littlefoot, suggesting she's aware of her son's [[IncrediblyLamePun taste]] in friends and doesn't seem particularly bothered by it.
* RedEyesTakeWarning: They aren't really villainous, but they are dangerous, and they have the eyes to match .

!!Ozzie and Strut - ''Struthiomimuses''
A duo of bumbling egg stealers who infiltrate the Great Valley in order to prey upon the smorgasbord of eggs within

Appears in film two only.

* BumblingSidekick: Strutt.
* ButtMonkey: Both of them, though Strut usually gets the worst of it.
* {{Determinator}}: Ozzie.
* EvilBrit: Ozzie.
* ExitPursuedByABear: They get chased off by Chomper's parents in the end.
* HeyItsThatVoice: Strutt is Pinky of PinkyAndTheBrain.
* LargeHam: Ozzie.
* LaughablyEvil
* JerkAss: Ozzie to Strut.
* [[StarterVillain Starter Villains]]
* ThoseTwoBadGuys
* VegetarianCarnivore: Ozzie and Strut are both Struthiomimuses. Strut seemed more content with eating plants, while Ozzie seems obsessed with eating eggs. In reality, Struthiomimus and its relatives were omnivores, [[TooDumbToLive and having such restricted diets would probably be a death sentence.]]
* VillainSong: 'Eggs'.

!!Hyp, Nod and Mutt - ''Hypsilophodon'', ''Nodosaurus'', and ''Muttaburrasaurus''
Appears in film three and an episode of the TV series.
* AesopAmnesia: They're back to being troublemakers in the TV series, but they're not as bad as they were in the third film so they probably at least learned something since then.
* BrainsAndBrawn: Hyp's the brains, Nod and Mutt are the brawn, but especially Mutt.
* ButtMonkey: Mutt gets slapped around a ''lot''.
* DeadpanSnarker: Hyp is quite the wiseass before he mellows out.
* {{Delinquents}}
* FrameUp: Get Littlefoot in trouble by pushing him into the water off a low cliff, making the scare resource scarcer due to the big splash. Littlefoot being Littlefoot doesn't say it was them, just that he'd been playing and fell.
* FreudianExcuse: Hyp's dad was even more hardass than Topsy. [[CallingTheOldManOut And Topsy's on of the adults to seriously call Hyp's dad out on it.]]
* GangOfBullies
* Big Thin and Short Trio: Mutt (big), Hyp (thin), and Nod (short).
* HeelFaceTurn: They start out as a bunch of bullying jerks to Littlefoot and his friends, yet they do come through in the end and helps save everyone from the Sharpteeth.
* {{Jerkass}} --> JerkWithAHeartOfGold
* VillainSong: 'When You're Big', a possible contender for the best song in the series.
* WellDoneSonGuy: Hyp, to the point that he still idolizes his father, despite his abusive ways. This turns out to be why he's such a bully in the first place; it's the only way he can interact with others, because it's all his father ever gave him.

!!Ali - ''Apatosaurus''
[[caption-width-right:300:"It takes all sorts to make our world."]]
A young female Apatosaurus from the land known as the Valley of the Mists. She is a Farwalker, along with the rest of her herd, and is constantly traveling.

Appears in film four and an episode of the TV series.

* DistaffCounterpart: Ali looks almost exactly like Littlefoot. Lampshaded by Petrie, who mistakes her for a second Littlefoot when he first sees her.
* FantasticRacism: Not as bad as Mr. Threehorn gets, but she initially wasn't comfortable interacting with dinosaurs who weren't longnecks.
* GuestStarPartyMember: In ''Journey Through The Mist''
* PaleFemalesDarkMales: Ali is more pinkish than Littlefoot, who is more grayish.
* WalkingTheEarth: Her herd is migratory, after their homeland was ruined by constant rain and floods.

!!Old One ''Apatosaurus''
The leader of a group of wandering longnecks called the farwalkers, she brings word of the outside world to the Great Valley and identifies a sickness that has overtaken Littlefoot's grandfather.

Appears in film four and an episode of the TV series.

* ReasonableAuthorityFigure: She clearly has the best interest of her herd in mind, and is shown to be happy when finding that a sharptooth can get along with plant eaters.
* WalkingTheEarth
* WouldHurtAChild: In an episode of the TV series, she and her herd chase and eventually corner Chomper over a misunderstanding. Chomper, sounding close to tears, begs that they don't hurt him, and after a few moments of marveling over the fact that they're dealing with a talking sharptooth, she and her herd decides they ''still'' want to kill him.

!!Ichy and Dil - ''Ichthyornis'' and ''Deinosuchus''
[[caption-width-right:300: Ichy-"I do all the REAL work around here. I'm the eyes!" Dil-"So? I'm the teeth!"]]
A squabbling male Ichthyornis and female Deinosuchus who partner together to hunt prey in the Valley of the Mists. They act as the main antagonists of the fourth film. Their whereabouts are unknown.

Appears in film four only.

* BrainsAndBrawn: Ichy is the planner, Dil is the muscle. They're useless without each other, as Ichy is too small to accomplish much and Dil is nearly blind.
* ExitPursuedByABear: after 'parting ways' with Ichy, Dill is chased off screen by a very hungry looking plesiosaur
* NeverSmileAtACrocodile: Dil, although she's a bit less competent than most.
* ShoutOut:
--> '''Dill''': [[{{Honeymooners}} "One of these-"]] *hits tree* [[{{Honeymooners}} "-days, Ichy-"]] *hits tree* [[{{Honeymooners}} "One of these-"]] *hits tree* "... Oh, forget it." *hits tree*
* TeethClenchedTeamwork: They are partners, not friends. They make it clear they're only together out of necessity.
* ThoseTwoBadGuys
* ToothyBird: Justified, as Ichy is an ''Ichthyornis'', which had teeth in real life.
* VillainSong: 'Who Needs You', all about how they can't stand each other, despite the fact that neither can survive without the other. It's done in a vaudeville style.

!!Elsie - ''Elasmosaurus''
An inexplicably British plesiosaur that accidentally frightens Chomper and Littlefoot. She gladly helps our dinosaurian heroes relocate their parents.
Appears only in film five.

* ArtisticLicensePaleontology: Her portrayal has.... several problems, The least of which being a shark fin being on her head for ''no reason''. In this movie she is essentially just a sauropod with flippers. Plesiosaurs were only very distantly related to dinosaurs at all, much less longnecks. She's also improbably huge.
* TheCameo: She may or may not be one of the Elasmosaurs that swim by in the beginning of the ninth film.
* HorseOfADifferentColor: Her main contribution to the film is giving Littlefoot & Co back to the mainland
* [[NiceGuy Nice Lady]]
* StockNessMonster: Her neck is in the same pose as the classic picture
* VegetarianCarnivore: Plesiosaurs were carnivorous. We never see Elsie eat, but she has noticeably flat teeth, and appears to be just an aquatic version of Littlefoot's grandparents.

!!Plated Sharptooth - ''Giganotosaurus''
An unnamed, vicious Giganotosaurus living on the Mysterious Island. He acts as the main antagonist of the fifth film. He's drowned after being pushed off a cliff into the ocean.

Appears only in film five.
* {{Badass}}
* DarkerAndEdgier: Sharpteeth, particularly unnamed ones, are generally portrayed as incompetent villains, but the Plated Sharptooth harkens more to the vicious, relentless threat of the original Sharptooth.
** He holds the distinction of being the only character other than the first Sharptooth to ever draw visible blood on screen.[[ He slashes Chomper's father's nose with his claws]], and then slashes his mother's leg with his toes.
* {{Determinator}}: Most sharpteeth in the series will run in fear the moment that adult ''flateeth'' make the scene. The Plated Sharpteeth was perfectly willing to stand and fight two other adult sharpteeth ''at the same time''.
** He does have one LighterAndSofter moment where he accidentally bites his own tail, tearing up as he does so.
* ImplacableMan: While not quite as unstoppable as the sharptooth of the first film, he's displayed unusual persistance by jumping over chasms and fighting off other sharpteeth in an attempt to get at the heroes.
* KnightOfCerebus: Calls back more to the original Sharptooth in terms of sheer viciousness. Aside from one aforementioned comedy moment, the Plated Sharptooth was ''much'' more serious than others of its kin.
* NoNameGiven: The movie never gives him a name, but the credits refer to him as 'The Plated Sharptooth'.
* RedEyesTakeWarning: His eyes are drawn in an unusually animalistic manner, with less expression, more prominently slitted pupils, and dark marks under his eyes. These mark him out as an unusually dangerous sharptooth.
* TakingYouWithMe: Similar to how the original sharptooth nearly dragged Petrie to the water with him when he falls, the Plated Sharptooth knocks Chomper off a cliff and into the ocean along with him.

!!Doc - ''Diplodocus''
[[caption-width-right:300:"Have it your way, kid."]]
A loner Diplodocus who fights away sharpteeth, and Littlefoot's idol. Littlefoot believes he is the legendary 'Lone Dinosaur' of myth. He's a wanderer, and constantly travels from place to place.

Appears in film six and an episode of the TV series.

* {{Badass}}
* ClintSquint
* TheDrifter
* {{Expy}}: The dinosaur version of Clint Eastwood.
* FantasticRacism: When he shows up in the series, he refuses to accept Chomper might be a good guy due to him being a Sharptooth. However, he ultimately learns the error of his ways when the little guy helps save his 'lady friend'.
* JerkWithAHeartOfGold: In the TV series, at least. In his first appearance, he isn't very personified.
* RedBaron: The Lone Dinosaur
* [[GoodScarsEvilScars Good Scar]]: A thin, jagged one over the right side of his face.
* WartsAndAll: Doc fits this trope from the time he condemns Littlefoot's friendship with Chomper until the time he repents for it.
* WhipItGood: What he uses his tail for.

!!Dana and Dinah - ''Triceratops''
Appears in film six only.

* AnnoyingYoungerSibling: For Cera, though they are apparently supposed to be her niece and nephew.
* ChuckCunninghamSyndrome: They disappear after ''Saurus Rock''. Presumably, they went back to live with their parents.
** Though, given their [[FearlessInfant total obliviousness to danger]], they may well have died.

!!Pterano - ''Pteranodon''
[[caption-width-right:300:"Petrie, I'm heartbroken. Didn't you recognise your dear old uncle?" ]]
An ambitious, cunning Pterosaur who takes an interest in the story of the Stone of Cold Fire. He's Petrie's maternal uncle, and an antagonist for much of the seventh film. He's been banished from the Great Valley for several years as punishment for kidnapping Ducky, and his current whereabouts are unknown.

Appears in film seven only, though is mentioned a few times in the TV series.

* AffablyEvil: He's a pretty nice guy, despite his nastier qualities.
* AntiVillain: Not really evil per se, but certainly selfish and very reckless. While he has put people in danger before, he never means to do so and wishes no harm on anyone.
* TheAtoner: Eventually.
* BigBad: Of ''Stone of Cold Fire'', [[HeelFaceTurn though he doesn't stay that way]].
* CoolUncle: Petrie thinks he is.
* DangerouslyGenreSavvy:
-->'''Rinkus''': Why not simply ask the longneck to tell us where [the stone of cold fire] is! (''makes a slashing motion over his neck'') Or else (''EvilLaugh before being smacked in the face by Pterano'')
-->'''Pterano''': Mr. Rinkus, if you threaten the young ones [[PapaWolf it will put the]] [[MamaBear elders on alert]]. They will [[ProperlyParanoid watch our every move]] and our cause will be lost! ''Now is THAT what you want!?''
-->'''Rinkus''': N-n-n-n-no! Of course not!
* DirtyCoward: Accused of being one, after his disastrous leadership.
* EvenEvilHasLovedOnes: He has a sister and a couple nieces and nephews, one who ''adores'' him. However, his sister is less than friendly when he shows up.
* EvenEvilHasStandards: He may be arrogant and somewhat nefarious, but he draws the line at [[WouldNotHurtAChild harming children]]. When he first mentions it, it sounds like PragmaticVillainy, but later he expresses genuine sorrow when Ducky appears to have fallen to her death and genuine horror when Sierra declares that the minute they become leaders he's going to throw the kids to the sharpteeth. Lampshaded by his sister, who states that while he's done many bad things, she knows he would never let Rinkus and Sierra harm Ducky.
* EvilBrit
* EvilUncle : But he has a HeelFaceTurn.
* ItsAllAboutMe: His theme song, "Very Important Creature" highlights this. He's motivated by a ''big'' superiority complex.
* JerkWithAHeartOfGold
* MyGodWhatHaveIDone: He has this response ''a lot''. Most notable is the one listed directly below.
* MyGreatestFailure: Pterano had once unintentionally led a group of followers into a fast biter (raptor), ambush, where everyone but himself was killed. He seems very haunted by this event.
* NeverMyFault: His FatalFlaw.
* {{Pride}}: He has a very overinflated opinion of his leadership abilities.
* PteroSoarer: Unlike his nephew, he was unlucky to be a sequel character, and hence whatever accuracy the original movie's pterosaurs had was not carried on.
* VillainSong: 'Very Important Creature', another contender for the best villain song of the series, mainly because rather than being about how nasty and vicious he is, this song is simply about how brave and strong he thinks he is, and how egotistical everyone else thinks he is.
* WellIntentionedExtremist: He legitimately believes himself to be a good leader and thinks that everyone would be better off with him as such.

!!Sierra and Rinkus - ''Cearadactylus'' and ''Rhamphorhynchus''
Two conniving pterosaurs that associate themselves with Petrie's uncle Pterano. However, they seem to have plans all their own...

Appears in film seven only.

* BrainsAndBrawn: [[ObfuscatingStupidity Rinkus]] is the brains and [[MurderIsTheBestSolution Sierra]] is the brawn.
* DangerouslyGenreSavvy: Rinkus points out to Sierra that it would be inconvenient to ''kill'' Pterano and instead opts to just tolerate him long enough to get power from the Stone of Cold Fire, then [[YouHaveOutlivedYourUsefulness dispose of him when he's no longer needed]].
-->'''Rinkus''': Just be patient; [[WhamLine let HIM lead US to the stone...]]
* DirtyCoward: Rinkus. Or so it seems...
* {{Foreshadowing}}: Rinkus' darker side is hinted at several times in the movie, like not so subtley implying that he wanted to threaten Littlefoot with violence or even ''death'' if he doesn't tell them the location of the stone.
* MurderIsTheBestSolution: Sierra suggests feeding the main characters to sharpteeth.
** Rinkus says that should kill Littlefoot if he doesn't give them information about the stone.
* NotSoHarmless: Rinkus, who proves himself to be a pretty nasty schemer on several occasions.
* ObfuscatingStupidity[=/=]BewareTheSillyOnes: Underneath his supposed stupidity, Rinkus is easily the smarter and more treacherous of the two.
* PragmaticVillainy: Rinkus, as opposed to the eccentric Pterano and [[ForTheEvulz just malevolent]] Sierra. His boss pisses him off and mistreats him? Goes perfectly in alignment with his will until muscle back up (in that case, his beligerent coleague) is conveniently availiable.
* PteroSoarer: Same as above.
* {{Smug Snake}}s: Both of them, but Rinkus moreso than Sierra.
* TheSociopath: They're both this, in different flavors; Sierra's the violent, hateful sociopath with [[LackOfEmpathy no empathy]], while Rinkus is the lying, deceitful sociopath who can convincingly fake emotions and manipulate people.
* TheStarscream
* ThoseTwoBadGuys

!!Rainbow Faces - ''Gallimimus''
A mysterious male and female Gallimimus who talk in riddles and seem to posses uncommonly advanced knowledge about the world. Their current whereabouts (if they're even still on Earth) are unknown.

Appears in film seven only.

* AlienAmongUs: Never directly addressed, but very, VERY heavily implied, both by their more-than-saurian knowledge of how the world works, and by the shimmering pillar of light that marks their departure.
* DeadpanSnarker: The female Rainbow Face.
* LikeAnOldMarriedCouple: How they generally act. [[ShipTease And they might be one]], but there's no confirmation.
* SayingTooMuch: A running gag with the male Rainbow Face, something his companion likes to point out.
-->'''Female Rainbow Face:''' Life is full of little mysteries, isn't it? (''turns to the male one'') And ''you'' are giving away too many of them!

!!Mr. Thicknose - ''Pachyrhinosaurus''
An old teacher who's responsible for giving young dinosaurs in the Great Valley their primary education. He lives alone in the Great Valley; it is unknown if he continues to teach or not.

Appears in film eight and several TV episodes.

* AscendedExtra: Appears in only one film, becomes a regular character in the TV series.
* CoolOldGuy
* KnowNothingKnowItAll: Originally respected as the smartest resident of the Great Valley, having "Been everywhere and seen everything", it is then revealed that he gets most of his knowledge from second-hand sources.
** Though he does put the information he's gained about landmarks to good use later on.
* YoungerAndHipper: The TV show has Mr. Thicknose with a significantly deeper, younger sounding voice, along with a more energetic personality. He also seems to have become far more open in his beliefs: while he refused to accept that snow could ever fall in the great valley in film eight, he seems perfectly willing to believe that there is such thing as an invisible dinosaur in the TV series.

!!Tippy - ''Stegosaurus''
Appears in film eight and one episode of the TV series.

* LivingProp
* ThirdPersonPerson: In the TV series.

!!Mo - ''Ophthalmosaurus''
An energetic Opthalmosaurus who befriends Littlefoot after he becomes trapped in the floodwaters of the Great Valley. He lives in the Big Water with the rest of his family.

Appears in film nine, makes cameos in films ten and twelve, and appears in one episode of the TV series.

* BloodBrothers: Sort of. In the ninth film, he and Littlefoot become 'mud brothers', a PG equivelant.
* DisneyDeath
* GuestStarPartyMember
* HeroicSacrifice: Narrowly escapes a swimming sharptooth when it changes direction while he hides in a hollow log.
* {{Keet}}: The little guy has tons of energy.
* StarfishAlien: If the Swimming Sharptooth is an EldritchAbomination from the kids' POV, then Mo is definitely one of these to them; a lot of attention is drawn to the fact that he's very different from them, although their differences are not treated as bad and it's made very clear that the only real way they're different is in physical appearance.
* ThirdPersonPerson

!!Sharptooth Swimmer - ''Liopleurodon''
A voracious carnivore from the sea, this swimming sharptooth is a long way from home to be sure, but he won't let that get in the way of a good meal.

Appears in film nine only.

* EvilCounterpart: To Mo. Both are non-dinosaurian reptiles from the ocean that are forcible taken from their homes and left in a newly made lake in the Great Valley. Unlike Mo, this one is a vicious carnivore.
* EldritchAbomination: To the kids. They've never seen anything like it, and Littlefoot even calls it a monster.
* KrakenAndLeviathan: Of the leviathan type.
* NeverSmileAtACrocodile: Not quite, but it's certainly meant to bring this trope to mind
* NonMaliciousMonster: The only reason it ever crosses paths with the heroes is because it's trapped in the Great Valley with Mo. It is a carnivore, so it does try to eat them, but its clear than it is just trying to get home, and stops antagonizing the kids after it smells the ocean.
* SeaMonster: Well, it ''is'' a Liopleurodon, so what did you expect? It to be eating cheese?

!!Bron - ''Apatosaurus''
[[caption-width-right:300:"Your mother and I knew we were going to have a hatchling."]]
A herd leader that partakes in the Great Longneck migration. He's Littlefoot's long lost father, and the adopted father of Shorty. Due to the responsibilities of being a herd leader, he does not live in the Great Valley with his biological son, but now visits the valley very frequently.

Appears in film ten and one episode of the TV series.

* {{Badass}}: Being the leader of his own heard doesn't mean he's gotten soft in how to fend off Sharpteeth. Must run in the family.
* DisappearedDad: He left to find a suitable place to live before Littlefoot's birth and by the time he returned, the Great Earthshake had occurred.
* GenreSavvy: Bron is, to date, the ''only'' adult in the film series that told Littlefoot to go help fight a Sharptooth, instead of to run away. Apparently, when Littlefoot described his childhood of [[CurbStompBattle beating every Sharptooth he encountered]], Bron was actually listening.
* GoodParents: When he does reunite with Littlefoot and makes amends with him, he is shown to be a very loving father to both him and Shorty.
* IThoughtYouWereDead: Bron's excuse for having never met his son until now.
* LightningBruiser: The only Longneck in the series to use a ''running start'' to attack a Sharptooth. Also the only one to not be defenseless when knocked off his feet--he just kicks the offending Sharptooth in the face and sends it rolling down a mountain.
* LikeFatherLikeSon: Looks remarkably like his son, such as having the same coloration. He's also a herd leader, much like Littlefoot who often acts like a herd leader to his friends during adventures.
* NamedLikeMyName: When he was younger, people used to give him the nickname 'little foot'. His wife knew this about him, and decided to name their son after this.
* OneHitKO: When he kicked a Sharptooth in the face in X, it went rolling down the mountain and didn't get up for about a minute. Which is a very long time, [[{{MadeOfIron}} where Sharpteeth are concerned.]]
* ParentalSubstitute: To Shorty.
* WhatTheHellDad: Doesn't show up until the tenth movie. Littlefoot is understandably upset that he's been a no-show for almost NINE SEQUELS.
** The plot of the fourteenth film (yes, it is still going), involves him not appearing for a visit to his son when he was expected. This may or may not end in tragedy.

!!Shorty - ''Brachiosaurus''
An orphaned, troubled young Brachiosaurus who travels with Bron's herd. Bron later officially adopts him, making him Littlefoot's adopted brother. He lives a nomadic life with his adopted father.

Appears in film ten and one episode of the TV series.

* BigBrotherBully: When he first meets Littlefoot, his future step-brother, he picks on him. This tendency abates once Bron agrees to adopt Shorty.
* BratsWithSlingshots: He uses his tail to smack pebbles at things with great precision.
* HappilyAdopted: By Bron.
* JerkWithAHeartOfGold[=/=]{{Jerkass}}
* LeaderWannabe: While Littlefoot is off taking the big longneck test, Shorty takes his friends on an adventure in his stead. It quickly becomes apparent that he has none of his step-brother's leadership talents.

!!Tria - ''Triceratops''
A pink triceratops who had courted Cera's father when they were young. She marries Topsy, becoming Cera's stepmother, and later gives birth to Patricia. She lives in the Great Valley with her husband, daughter, and stepdaughter.

Appears in films eleven, twelve, and thirteen, as well as multiple TV episodes.

* BeastAndBeauty: She seems to be the only adult in the series capable of soothing Cera's hot-headed father.
* BroodingBoyGentleGirl: The gentle girl to Topsy's brooding boy.
* EvilStepmother: Averted. Despite an initial clash, Tria has shown herself to be a good stepmother who loves and watches out for her stepdaughter Cera.
* GoodParents: In Cera's case, good stepparents.
* MinnesotaNice: In the TV series, at least. There are hints of the accent in her inflections, and she certainly has the polite behavior.
* NewOldFlame
* WhatHappenedToTheMouse: What happened to Cera's real mother, considering we never see her at the end of the first film? Considering the perils of the journey to the Great Valley, [[FridgeHorror she died on the trip along with every member of her final clutch except for Cera]].

!!Guido - ''Microraptor''
Appears in film twelve and one episode of the TV series.

* ButtMonkey
* InstantExpert: Has no problem flying, as long as he is asleep. Later learns to do it for himself.
* LastOfHisKind: Allegedly, likely stemming from...
* LaserGuidedAmnesia: He wakes up in the Great Valley and has no idea where he is, what he is, where he came from, how he got here...
* RememberedICouldFly: See above, and only after everyone tells him he can.
* PluckyComicRelief: Pulled off decently for a direct-to-DVD character.

!!Loofa and Doofa - ''Beipiaosaurus''
Appears only in film thirteen.

* CallARabbitASmeerp: They're referred to as 'Yellow Bellies'
* [[CloudCuckooLander Cloud Cuckoo Landers]]
* DoesThisRemindYouOfAnything: Doofa has a habit of calling Cera beautiful. That combined with picking her up the first time they meet, well...
* EscortMission: They seem so naive, incompetent, and clumsy that Littlefoot actually feared for their safety when they mention they're traveling alone, to the point of having nightmares about them meeting some horrible fate. He decides it would be best if he and his friends tag along to keep an eye on them.
** This can also count as AdultsAreUseless, or perhaps more aptly, Adults Are Helpless.


[[folder:The television series]]
!!Ruby - ''Oviraptor''
[[caption-width-right:300:"Hello, my friends, my friends hello!"]]
A whimsical female oviraptor who acts as Chomper's guardian in the Great Valley while he lives away from his parents. She and Chomper live in the Secret Caverns, a system of caves in the Great Valley. She becomes a main character in the TV show.

* CloudCuckooLander:
--> '''Ruby''': "I'm right here... Of course, I'm ''always'' "here", and "here" is where ever I am."
* CoolBigSis: Ruby is the oldest of the kids and goes between this and TeamMom.
* GenkiGirl
* NiceGirl
* ParentalSubstitute: She acts as a guardian to Chomper while he lives in the valley.
* RememberTheNewGuy: She and Chomper are already with the main cast on the first episode without any mention of her past. Even though she gets more details explained later it's quite {{egregious}}.
* ShownTheirWork: Her species are portrayed with feathers and as omnivores instead of egg-eaters.
* [[SixthRanger Seventh Ranger]]
* TomboyAndGirlyGirl: GirlyGirl to Cera's {{Tomboy}}. (One of two)
* [[VegetarianCarnivore Vegetarian Omnivore]]: Averted. While she likes eating plants (her favorite food is grapes, in fact), she's also seen eating a shellfish at one point, which would classify her as an omnivore. [[ShownTheirWork You know, just like real Oviraptors were]].
* VerbalTic: Tends to say things twice, but the second time switching the structure of the statement around. [[MostAnnoyingSound It can get a tad annoying]], but does provide a thoughtful line here and there.

!!Red Claw - ''TyrannosaurusRex''
An uncommonly powerful Tyrannosaurus who's terrorizing the mysterious beyond. He lives on the outskirts of the Great Valley.

* BigBad: Of the TV Series
* {{Expy}}/ShoutOut: Of the original Sharptooth. Just like the original sharptooth, Red Claw causes such widespread fear that even other sharpteeth try to keep away from him. Also telling is his one discolored eye, likely a reference to the original sharptooth getting stabbed in the eye with a thorn.
* [[GoodScarsEvilScars Evil Scars]]
* InformedAbility: He's said to be one of the biggest, baddest Sharptooth of all time, but he's constantly defeated by a group of children...though said children have a long record of beating Sharptooth.
** That said, he's never shown to be nearly as vicious as the original sharptooth.

!!Screech and Thud - ''Utahraptor''

* EvilIsDumb
* {{Evil Minions}}
* MakesUsEven: Not long after Chomper helps free him from a pile of rocks, Thud finds him and the rest of the gang trapped inside a small cave near a canyon wall. Instead of alerting Screech and Red Claw, he leads them in the opposite direction of where the kids are hiding.
* RaptorAttack: Besides lacking feathers, they have two fingers instead of three.

!!Rhett - ''Apatosaurus''

* BreakTheHaughty: Brags that sharpteeth fear him...until he has to deal with an actual one. And said actual sharptooth isn't even bigger than him.
* DirtyCoward: The exact instant he's faced with a real sharptooth, he turns tail and runs. What makes this different from the other characters is that this sharptooth was about a tenth his size.
* MilesGloriosus: He brags about outlandish feats of strength and bravery to impress people. Littlefoot and Cera aren't fooled by Rhett's stories, but Ali is.

!!Milo, Lydia, and Plower - ''Ceratogaulus''

* AnachronismStew: ''Ceratogaulus'' or horned gophers lived from the Milocene to the Pleistocene, ''after'' the dinosaurs became extinct.
* NayTheist: Plower was initially skeptical that Spike was "The Big Wise One", but becomes convinced when Spike inadvertently defeats the Great Hideous Beast.
* SeldomSeenSpecies: Probably the first time you see horned gophers in a cartoon.

!!Great Hideous Beast - ''Microceratus''

* KillerRabbit: Subverted. Due to his tiny size he can barely pose a threat to Spike, who defeats him and traps him in a rock pile by mere accident.

!!Dara - ''Diplodocus''

* LoveInterest: For Doc.

!!Scuttle - Crustacean

* [[DefrostingTheIceQueen Enraging the Ice Queen]]: Scuttle abuses the fact that the gang needs his help by sending them on dangerous [[FetchQuest fetch quests]] for his favorite food. Cera is aware she's being taken advantage of, and she is ''not'' happy about it. His third request which was to build him a nest becomes the last straw for Cera.
* {{Expy}}: A greedy, confrontational crab with long eyestalks, a pirate accent, a penchant for telling stories, and a chortling laugh? [[SpongebobSquarepants All he's missing is a burger-joint.]]
* [[JerkassHasAPoint Ice Queen Has a Point]]: When it becomes clear that Scuttle has no real intent on going to the Great Valley to help with the sand creepers, Cera points out that he'll have no one to tell any of his stories to. Unable to bear having no one to tell stories to, he abides by the gang's request.
* {{Jerkass}}
* {{Omniglot}}: He's apparently the only crab capable of communicating with dinosaurs.
* TeethClenchedTeamwork: Because Scuttle is the only person capable of communicating with the [[CallARabbitASmeerp sand creepers]] that have infested the Great Valley, the gang can't afford to refuse his requests. But as scuttle keeps asking for more favors, the gang's patience rapidly wanes-- particularly Cera.

!!Crunch - Crustacean

* ArchEnemy: To Spike, despite Ducky thinking otherwise. Crunch keeps snapping painfully onto Spike's nose whenever the oppertunity presents itself. Spike eventually gets so irritated that he chases Crunch out of the valley.
* {{Jerkass}}

!!Swooper - ''Harpactognathus''

* {{Cloudcuckoolander}}: All those years of living as a hermit (and possibly as well as his blindness) have caused him to become acquainted with some cave formations, even giving them names. This is even lampshaded by Guido.
* CoolOldGuy
* PteroSoarer

!!Skip - Mammal

* HeliumSpeech: And he resembles a chipmunk to boot.
* MotorMouth
