'''Original film''':
* ExecutiveMeddling: The film was originally DarkerAndEdgier, but many scenes were deleted because they were [[AnimationAgeGhetto "too scary for kids"]]. This explains the film's very short running time.
** It should be noted that for older viewers, it would have simply made the film better. Which is why fans are trying desperately to track down these scenes.
* FanNickname: To avoid confusion between this character and sharpteeth as a whole, fans often refer to the film's antagonist as 'The Original Sharptooth' or simply '''The'' Sharptooth'.
* WhatCouldHaveBeen: The film's second half was not as Don originally intended. In the original version, Littlefoot finds the Great Valley after he goes off alone and the others go with Cera. He realizes that he has to go find the others, because they won't find it on their own, and goes back after them. The Sharptooth scene then happens and he leads them to the valley. This can be detected in the final film. Look at the scene where Littlefoot is telling his mother he'll never find the great valley because it's too hard. The rock they pushed onto Sharptooth is still there in the background.
** There is also a deleted scene where the group finds an oasis, but the two groups of dinosaurs already there get discriminatory, and say that only Ducky can drink.
*** These elements still appear in the children's books released with the film.
** Other things changes include: The scene where Sharptooth lands on the back of Littlefoot's mother was originally fully visible, but it was changed to shadow. The scene where Sharptooth is pushed under by the big rock had a scene where Sharptooth was seen looking up to the water, but it was also deemed too scary. Fans have gone out of their way to find all these scenes. [[TimeWillTell Hopefully they'll be found in the future...]]
** Old Rooter didn't appear in the original script, but was added to soften the blow of the death of Littlefoot's mother.
** The original film trailer has another apparently deleted bit from the final scene with Ducky saying "now we'll always be together!".
** Reportedly the full, uncut version has aired in several foreign countries.
* Sadly, Creator/JudithBarsi, the young actress who played Ducky in the original film (and she also played Anne-Marie in ''AllDogsGoToHeaven''), [[PaterFamilicide was murdered along with her mother by her father]] in a MurderSuicide a few months before this movie was released in theaters.
* The instrumental "If We Hold On Together" score was re-used in the live action film ''Lorenzo's Oil''.

'''Sequels''':
* ActorAllusion: Rinkus, Pterano's BumblingSidekick with the cockney accent, is pink. Guess, just guess who voices him.
** For those who can't be bothered to guess or Website/{{Google}}, it's [[spoiler:[[Creator/RobPaulsen Rob]] [[PinkyAndTheBrain Paulsen]].]]
* CreatorBacklash: While he had no involvement with them, Don Bluth dismissed the sequels offhand as [[StrictlyFormula "Cookie cutter thing(s)"]] [[http://www.ign.com/articles/2000/06/13/interview-with-don-bluth-part-1-of-3 in an interview.]] In [[http://www.digitpress.com/library/interviews/interview_don_bluth.html another interview]], he said;
->''"--with Land Before Time, of course it did make money--it made a lot of money. And so all the sequels, they just said, "Let's create a franchise here, let's create something that goes on and on and on." And each one of them have made money, because basically the children who watch it just see the little characters they love and so they're not discerning about whether it looks great or it's a great story or anything."''
* FranchiseKiller: ''Wisdom of Friends'' ensured that no more Land Before Time sequels were made. The TV series is stillborned.
* HeyItsThatGuy: Both Creator/StevenSpielberg and GeorgeLucas are executive producers of the first movie.
* HeyItsThatVoice:
** For the original, [[NewsiesSpot Conlon]] leads Cera, [[AllDogsGoToHeaven Ann-Marie]], and [[WesternAnimation/AnAmericanTail Digit]] to the Great Valley
** [[WesternAnimation/AnAmericanTail Digit]] however gets replaced by [[WesternAnimation/BatmanTheBraveAndTheBold The Joker]] as Petrie
** [[WesternAnimation/{{Recess}} Cornchip Girl]] is Ducky, and Ashley A. eventually becomes Cera
** Hey! It's [[VideoGame/HalfLife2 Eli Vance]] in VII!
** Not only will Littlefoot grow up to be [[TheSarahConnorChronicles the future leader of the resistance against Skynet]], but his dad is [[Series/TwentyFour Jack Bauer]]!
** Strut is [[PinkyAndTheBrain Pinky]]
** Grandpa Longneck is [[Disney/TheLittleMermaid King Triton]]
** The Japanese-dubbed version has some alumni from the Anime/{{Pokemon}} anime series and Franchise/{{Gundam}} in the cast:
*** Little Foot was voiced by Creator/MinamiTakayama from the second film to the twelfth, when she was [[TheOtherDarrin replaced]] by EtsukoKozakura.
*** Creator/MaayaSakamoto did her voice acting debut when she was a kid (and NOT in [[VisionOfEscaflowne Escaflowne like many people thinks]], since it was her break-out role there) as Cera from the first movie to the fourth film, when she was later replaced by RicaMatsumoto from the fifth film upwards.
*** Chomper [[Creator/IkueOtani is]] [[{{Pokemon}} Pikachu]] and [[OnePiece Tony Tony Chopper]]
*** Ali [[TomoSakurai is]] [[{{Macross7}} Mylene Jenius]]
*** Petrie [[Creator/YujiMitsuya is]] [[CombattlerV Hyoma Aoi]] and [[DragonBallZ Kaioh-shin]] and [[Creator/UraraTakano his mom is]] [[VideoGame/SakuraWars Maria Tachibana.]]
*** Topsy [[Creator/JojiNakata is]] [[Anime/{{Hellsing}} Alucard]]
*** Ducky [[Creator/SatomiKoorogi is]] [[Anime/ExcelSaga Menchi]]
*** Strut [[HideyukiUmezu is]] [[Anime/MobileSuitGundam00 Ian Vashti]] and [[VideoGame/SuperRobotWarsOriginalGeneration Vindel Mauser]] (And just like his original English voice actor, he also voiced [[PinkyAndTheBrain Pinky]] in Japanese too)
*** Doc [[AkioOhtsuka is]] [[Franchise/MetalGear Solid Snake]], [[Anime/MobileSuitGundam0083StardustMemory Anavel Gato]] and [[VideoGame/StreetFighterIV Seth]]
** Ichy is voiced by the titular character of ''WesternAnimation/JohnnyBravo'', while Dill is voiced by ''WesternAnimation/TheSimpsons'' character, Mrs. Skinner.
** Bron, Littlefoot's father, is voiced by Kiefer Sutherland.
** Loofa is voiced by academy award winning actor, Cuba Gooding Jr.
** Rhett has the same voice as Tommy Pickles from ''AllGrownUp''.
** In Italian and Swedish, Petrie is [[Anime/{{Pokemon}} Ash Ketchum]].
** In Germany,Ducky is [[WesternAnimation/MyLittlePonyFriendshipIsMagic Fluttershy]].
** In Spain, Littlefoot is [[TheFairlyOddParents Timmy Turner]].
** In Mexico, Littlefoot is [[WesternAnimation/SonicSatAm Princess Sally]].He's [[WesternAnimation/MyLittlePonyFriendshipIsMagic Rarity]] too.
* ScienceMarchesOn: Averted. Loofa and Doofa don't bear even a remote resemblance to what Beipeiaosaurus actually looked like.
** Technically speaking, the Yellow Bellies resemble generic therizinosaurs. Very, ''very'' cartooninised therizinosaurs. When they were concepted, there wasn't a lot of Beipiaosaurus material to go by, so their appearence wasn't so offensively backwards.
* RetroactiveRecognition: In a HeyItsThatGuy[=/=]HeyItsThatVoice hybrid example, in the tenth film, ''The Great Longneck Migration,'' Littlefoot's father is voiced by [[Series/TwentyFour Kiefer Sutherland.]] Really.
* TalkingToHimself: Not only did John Ingle provide the voice of Cera's father in the sequels and the TV series, but he was also the narrator for the sequels as well.

'''TV Series''':
* ScienceMarchesOn: Ruby's design includes feathers.
