Debuted in The Land Before Time II: The Great Valley Adventure
Appear in films two and five.
- Badass Adorable: And they're downright adorable when they're with their son.
- Battle Couple: You can bet if one's fighting, the other's about to jump in for a Big Damn Heroes moment if he/she's not preoccupied with another dinosaur.
- Deadpan Snarker: Chomper's father. "Sometimes I worry about that boy."note
- Good Parents: They really do love Chomper and will go to great lengths to protect him.
- Green and Mean: Subverted. They have green scales, are menacing predators, and initially play an antagonistic role, but it turns out they're not bad once you get to know them.
- Happily Married: For a pair of predators, they care for each other just as much as they do their son, to Battle Couple levels.
- HeelFace Turn: 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.
- Made of Iron: Much like all sharpteeth, nothing seems to be able to put them down.
- Mama Bear/Papa Wolf: 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.
- Monster Is a Mommy: They leave the Great Valley as soon as they find their son.
- Noodle Incident: How Chomper's family made it off the Mysterious Island after the isthmus linking it to the mainland was destroyed is unknown. It's also unknown how they came to meet Ruby, how they came to trust her enough to oversee their son's safety in the Great Valley, and where they are by the time of the TV series.
- Open-Minded Parent: Mama Sharptooth gives a rather deliberate sounding Double Entendre when she finds Chomper hanging around with Littlefoot, suggesting she's aware of her son's taste in friends and doesn't seem particularly bothered by it.
- Pale Females, Dark Males: They have green skin, but Mama Sharptooth's is a noticeably lighter shade.
- Red Eyes, Take Warning: They aren't really villainous, but they are dangerous, and they have the eyes to match .
Appear in film two only.
- Big Brother Bully: Ozzie doesn't listen to Strut about his desire to eat plants and forces him eat a diet comprised of eggs.
- Big Bad Duumvirate: Their theft of Chomper's egg is what brings his parents to the Great Valley.
- Bumbling Sidekick: Strutt mostly seems to go along with what Ozzy says, although he does come up with the idea that results in the two crossing the Moral Event Horizon.
- Butt-Monkey: Both of them, though Strut usually gets the worst of it.
- Exit, Pursued by a Bear: They get chased off by Chomper's parents in the end.
- Jerkass: Ozzie to Strut.
- Not-So-Harmless Villain: For most of the film, Strut was seen as the Butt-Monkey and was constantly being pushed around by his older brother. However, he proves to be just as devious as Ozzie by suggesting they throw Littlefoot off the Great Wall.
- Vegetarian Carnivore: 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, and having such restricted diets would probably be a death sentence.
- Villain Song: 'Eggs'.
- Would Hurt a Child: Not only does Strut suggest they kill Littlefoot by throwing him off of a cliff, Ozzie attempts to strangle Chomper, who had hatched just hours prior.
Debuted in The Land Before Time III: The Time of the Great Giving
- Aesop Amnesia: They're back to being troublemakers in the TV series, but at least seem to have learned somewhat.
- Big-Bad Ensemble: While they're the main antagonists to the children in Time of the Great Giving, the bigger problems come from Topps's taking charge of the valley and the drought itself.
- Big, Thin, Short Trio: Mutt (big), Hyp (thin), and Nod (short).
- Brains and Brawn: Hyp's the brains, Nod and Mutt are the brawn, but especially Mutt.
- Butt-Monkey: Mutt gets slapped around a lot.
- Deadpan Snarker: Hyp is quite the wiseass before he mellows out.
- Frame-Up: Get Littlefoot in trouble by pushing him into the water off a low cliff, making the scarce resource scarcer due to the big splash. Littlefoot being Littlefoot doesn't say it was them, just that he'd been playing and fell.
- Freudian Excuse: Hyp's dad was even more hardass than Topps. And Topps's on of the adults to seriously call Hyp's dad out on it.
- Gang of Bullies: They're very keen on antagonizing Littlefoot and his friends for being smaller and weaker than they are throughout Time of the Great Giving. While they learn their lesson by the end of the film, they still retain a mean streak when they show up in the TV series.
- HeelFace Turn: 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.
- Informed Species: Hyp doesn't even vaguely resemble Hypsilophodon (known for being a Ridiculously Cute Critter among dinosaurs and, contrary to the group's big villain song, very small in size), while Mutt looks more like some kind of hadrosaur than a Muttaburrasaurus. The only one who actually does resemble the dinosaur he's based on is Nod.
- Meaningful Name: All three seem to derive their names from their genuses: Hypsilophodon, Nodosaurus, and Muttaburrasaurus.
- Original Position Fallacy: They think they have the right to do what they want to Littlefoot and his friends because they're bigger than them, but it's pointed out their victims will inevitably grow bigger than them.
- Seldom-Seen Species: All three of them. Hypsilophodon, Nodosaurus, and Muttaburrasaurus are not the kind of dinosaurs you'd normally see in media.
- The Social Darwinist: Believe they can do whatever they want to those smaller than them.
- Took a Level in Kindness: They become much nicer by the end of the movie.
- Villain Song: 'When You're Big', a possible contender for the best song in the series.
- "Well Done, Son!" Guy: 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.
Appears in films three, five, seven, eleven, twelve and fourteen.
- Big Eater: Hes seems to be gluttonous, as he eats the days first treestar in film five without a second thought,
- Cool Old Guy: When hes not grumpy he can be a very nice man, as seen when he politely greets the gang at the beginning of film five.
- Jerk with a Heart of Gold: Hes generally a gruff man with a soft side to him, although sometimes he isnt gruff at all, like in The Mysterious Island.
- Whip It Good: His clubtail or bopper is a handy tool for fighting off sharpteeth, as seen in Time of the Great Giving. He seems to be able wield it with a great degree of control, as hes able to give Guido a demonstrative smack without significantly harming him despite Guido being much smaller and lighter than he is.
Debuted in The Land Before Time IV: Journey Through the Mists
Appears in film four and the TV episode The Brave Longneck Scheme.
- Voiced by:
Juliana Hansen (IV)
Nika Futterman (TV series)
- By the Lights of Their Eyes: How she is introduced.
- Distaff Counterpart: Ali looks almost exactly like Littlefoot. Lampshaded by Petrie, who mistakes her for a second Littlefoot when he first sees her.
- Distress Ball: Ali seems to uncharacteristically buy Rhett's bald-faced lies to the point that she'll side with him over her old friends Littlefoot and Cera. Not only that, it's shown that Ali doesn't even always like being around Rhett, but doesn't seem willing to stand up to him, which is a far cry from her bold personality from the fourth film.
- Fantastic Racism: Not as bad as Mr. Threehorn gets, but she initially wasn't comfortable interacting with dinosaurs who weren't longnecks.
- Genki Girl: Has a mild case of this when she first meets Littlefoot, gleefully hiding from him and playing pranks on him before they've even said hello. She later cheers him up from a low mood by a pulling a series of goofy faces. This attitude is quick to disappear when the other characters show up though.
- Guest-Star Party Member: In Journey Through The Mist.
- Innocent Blue Eyes: A nice, generally sweet tempered girl. Her discomfort around other species is a result of lack of experience in interacting with them.
- One Head Taller: Despite being a near identical Palette Swap of Littlefoot, Ali does appear to be a little shorter. e.g: ◊
- Pale Females, Dark Males: Ali is more pinkish than Littlefoot, who is more grayish.
- Pink Means Feminine: Her skin tends to have a pink tinge, which the main physical difference between her and Littlefoot.
- Walking the Earth: Her herd is migratory, after their homeland was ruined by constant rain and floods.
- What Happened to the Mouse?: Until she eventually popped up briefly in the TV show, fans spent a long time wondering if Ali would ever return, especially since the fourth movie had pretty much promised she would. A change in directors between the fourth and fifth movies may have been the cause of this, though it's unknown what, if any, kind of plans regarding Ali's return originally existed.
Appears in film four and the TV episode The Brave Longneck Scheme.
- Voiced by:
Carol Bruce (IV)
Jessica Walter (TV series)
- Good Scars, Evil Scars: She has deep scars running down the left side of her face. While it's never explained where she got them, they appear to be claw mark scars from some sharptooth she encountered in her past.
- Reasonable Authority Figure: 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.
- Took a Level in Jerkass: In the TV series, she and her herd are prettily willing to kill, or at least injure, Chomper.
- Walking the Earth: She's in charge of a migrating herd.
- Would Hurt a Child: 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 decide they still want to kill him. Given the fact that Chomper is both very outnumbered and very tiny compared to the longneck herd this seems extremely out of character for Old One. To be fair, Old One hesitates after hearing him talk, and only goes through with it after another herd member convinces her that it's for the good of the valley (and afterward, she still seems very reluctant).
Appear in film four only.
- Ambiguous Situation: We never learn what happened to them at the end of the movie. Fed up with him, Dil sent Ichy flying off in one hit of her tail, right before being chased by an hungry plesiosaur. We don't know if either of them survived their ordeal.
- Artistic License Paleontology: Ichy shouldn't really be interested in hunting dinosaurs or living inland like he is—Ichthyornis was a coastal, seagull-like predator that would almost certainly have eaten tiny marine creatures, as well as occasional carrion. Otherwise, he and Dil are rarities in the film series in that they both manage to avert this trope for the most part; while they're obviously stylized to make them look more villainous, they at least manage to look and move like the animals they're supposed to be (no doubt because both resemble animals that are still around today: Birds and alligators).
- Big Bad Duumvirate: The main antagonists of the fourth film.
- Brains and Brawn: 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.
- Exit, Pursued by a Bear: After 'parting ways' with Ichy, Dill is chased off screen by a very hungry looking plesiosaur.
- Feathered Fiend: Ichy is an evil bird.
- Laughably Evil: Half the time, they are used for comic-relief, whether because they are arguing with each other or because they are suffering bad luck and Amusing Injuries. However, the other half of the time, they are Not So Harmless Villains.
- Meaningful Name: Ichy stems from "Ichthyornis" and is pronounced like "icky", reflecting his personality. Dil appears to be derived from "crocodilian".
- Never Smile at a Crocodile: Dil, although she's a bit less competent than most.
- Not-So-Harmless Villain: They alternate between being used for comic-relief and being very close to eating the heroes.
- Red Eyes, Take Warning: Dil's eyes are bright red and she's a serious threat to the main characters.
- Smug Snake: Ichy moreso than Dil, being the schemer of the two who's far too full of himself for his own good. Dil is also pretty smug, though.
- Stock Dinosaurs: Well, only one of them is an actual dinosaur, but they still qualify. Ichthyornis is more commonly seen in educational media, while Deinosuchus is slightly more well-known.
- Teeth-Clenched Teamwork: They are partners, not friends. They make it clear they're only together out of necessity.
- Those Two Bad Guys: Always seen together, in spite of their mutual dislike of each other.
- Tiny Guy, Huge Girl: Ichy is a small bird, while Dil is a massive crocodilian.
- Toothy Bird: Justified, as Ichy is an Ichthyornis, which had teeth in real life.
- Villain Song: '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.
Appears only in film four.
- Voiced by: Charles Durning
- Artistic License Paleontology: Archelons were a sea dwelling species, and probably never inhabited far-inland caves even if those caves had water in them.
- Cool Old Guy: He's rather old, but helps Littlefoot fighting off Ichy and Dil.
- Guest-Star Party Member: Unlike Ali, Archie only joins the group until they leave the cave system that leads up to the Land of Mists.
- Guttural Growler: His first scene has him growling at an isolated Littlefoot in a way that makes him look like a threat, but he quickly mellows out once he sees that Littlefoot is just a lost kid and not a Sharptooth.
- The Hermit: He lives in a cave, and so doesn't usually see too many guests.
- Jerk with a Heart of Gold: At first, he tries to scare Littlefoot away, but he quickly mellows out once he sees that Littlefoot is just a lost kid and agrees to help him.
- What Happened to the Mouse?: He doesn't go with the group in the Land of Mists and stays in the cave system. The heroes don't get to meet him back, even when they leave the Land of Mists.
- Wise Old Turtle: He's quite elderly, dispensing valuable wisdom to the main characters and even comes to their rescue on a number of occasions.
Appears only in film four.
- Voiced by: Frank Welker
- But Now I Must Go: Chooses not to return to the great valley with the dinosaurs, presumably because his main family was still in the valley of mists.
- Cheerful Child: Has a perpetual smile, and doesn't seem to be any more mature then the other dinosaurs. Still counts as Vague Age, though.
- Known Only by Their Nickname: Since he can't talk normally, Ducky named him Tickles since he's the only one with fun hair on his body.
- Nice Mice: He resembles a mouse, and is friendly and helpful towards the Gang.
- Odd Friendship: Even though they're only together for a little while, he and Spike seem to hit it off pretty well with each other.
- Pint-Sized Powerhouse: While normally seen rolling rocks only a little bigger than himself, when he can pick up Dil's tail and drag it around without much difficulty, that's more of a surprise given he's smaller than ducky.
- The Unintelligible: Speaks only in squeaks, though the others seem to understand him fine.
- What Happened to the Mouse?: Literally, since he's a prehistoric mouse. He hasn't returned in any of the sequels or the TV series, despite the return of so many other characters. He probably still lives in the valley of the mists.
Debuted in The Land Before Time V: The Mysterious Island
An inexplicably British plesiosaur that accidentally frightens Chomper and Littlefoot. She gladly helps our dinosaurian heroes relocate their parents.
Appears only in film five.
- Voiced by: Christina Pickles
- Artistic License Paleontology: 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. Oddly, a much more accurate plesiosaur appeared in the previous movie.
- The Cameo: She may or may not be one of the Elasmosaurs that swim by in the beginning of the ninth film.
- Horse of a Different Color: Her main contribution to the film is giving the kids a safe ride back to the mainland.
- Nice Girl: Is very kind and helpful, immediately volunteering to reunite the kids with their parents.
- Stock Ness Monster: Her neck is in the same pose as the classic picture.
- Vegetarian Carnivore: 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.
Appears only in film five.
- Big Bad: Of the last act of Mysterious Island.
- Darker and Edgier: 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. And no, it didn't get edited out this time.
- He does have one Lighter and Softer moment where he accidentally bites his own tail, tearing up as he does so.
- Determinator: Most sharpteeth in the series will run in fear the moment that adult flateeth make the scene. The Plated Sharptooth was perfectly willing to stand and fight two other adult sharpteeth at the same time.
- Disney Villain Death: Falls right into the ocean.
- Implacable Man: 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.
- Knight of Cerebus: 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.
- No Name Given: The movie never gives him a name, but the credits refer to him as 'The Plated Sharptooth'.
- Red Eyes, Take Warning: 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.
- Taking You with Me: Similar to how the original sharptooth nearly dragged Petrie into the water with him when he falls from the precipice in the first film, the Plated Sharptooth knocks Chomper off a cliff and into the ocean along with him and nearly causes him to drown.
Debuted in The Land Before Time VI: The Secret of Saurus Rock
Appears in film six and the TV episode The Lone Dinosaur Returns.
- Clint Squint: He's rarely seen without one, just like the actor he's a clear Expy of.
- The Drifter: Leads a nomadic lifestyle.
- Expy: The dinosaur version of Clint Eastwood.
- Fantastic Racism: 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'.
- Good Scars, Evil Scars: A thin, jagged one over the right side of his face.
- Jerk with a Heart of Gold: In the TV series, at least. In his first appearance, he's more of a silent, enigmatic wanderer whose moralities— outside of fighting sharpteeth— are unknown.
- The Jinx: The events of the sixth film cause the Great Valley residents to pin the blame on his arrival to the valley as a harbinger of bad luck. While he doesn't particularly seem to care about the negative reputation he has, it is a stigma that's stuck with him all the way up to his reappearance in the TV series.
- Meaningful Name: Likely comes from his genus name of Diplodocus.
- Red Baron: The Lone Dinosaur
- Riddle for the Ages: Is Doc the Lone Dinosaur of legend? An answer is never given, and there's evidence that both supports and denies this claim. The film leaves it ambiguous wether the fight sequence that plays out during grandpa longneck's story is a depiction of a real event or simply Littlefoot's visualization. Curiously, the 'Biggest, Meanest Sharptooth' is a dead ringer for the Sharptooth from the original film, someone Littlefoot has met before, while the Lone Dinosaur looks just like Doc, who he's about to meet.
- The Stoic: It's hard to tell what he feels half the time. Even in a clear moment of displeasure, like when he finds out about Littlefoot's friendship with Chomper, he seems self-restrained in his emotions.
- Tag Along Kid: Doc seems to see Littlefoot as this. While he doesn't discourage Littlefoot from trying to imitate him and does seem to genuinely like him, he usually has other things on his mind than trying to impress a local longneck boy.
- Warts and All: Doc fits this trope from the time he condemns Littlefoot's friendship with Chomper until the time he repents for it.
- Whip It Good: What he uses his tail for.
Appear in film six only.
- Annoying Younger Sibling: For Cera—although she's technically their aunt and not their older sister.
- Baby Talk: They talk in an unintelligible babble. Humorously lampshaded by Cera as she tearfully remembers their 'first words'.
- Can't Live With Them, Can't Live Without Them: Despite how annoyed Cera often is with them, she's legitimately distraught when she thinks something bad has happened to them.
- Chuck Cunningham Syndrome: They disappear after Saurus Rock. Presumably, they went back to live with their parents.
- Cousin Oliver: Seemingly introduced as this, although they quickly disappear after their first appearence.
- Fearless Infant: They are totally oblivious to any kind of danger!
- Parental Abandonment: Their parents are nowhere to be seen. Interestingly, despite one of them likely being a sibling of Cera's, they don't resemble Cera at all.
Debuted in The Land Before Time VII: The Stone of Cold Fire
Appears in film seven only, though is mentioned a few times in the TV series.
- Voiced by: Michael York
- Affably Evil: Despite his nastier qualities and his rampant ego, he ultimately doesn't mean to hurt anyone and atones for his actions by the end of the film.
- Anti-Villain: 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.
- The Atoner: Eventually, he agrees that he has to be held accountable for his actions and promises that, after the end of his banishment, he will return to the herd and prove that he can be trust-worthy.
- Big Bad: Of Stone of Cold Fire, though he doesn't stay that way.
- Cool Uncle: Petrie thinks he is.
- Dirty Coward: Accused of being one, after his disastrous leadership.
- Even Evil Has Loved Ones: 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.
- Even Evil Has Standards: He may be arrogant and somewhat nefarious, but he draws the line at harming children. When he first mentions it, it sounds like Pragmatic Villainy, 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.
- Evil Brit: He's one of only a few characters in the series with a clear British accent, and is the main villain for most of his movie.
- Evil Uncle : But he has a HeelFace Turn.
- The Exile: At the end of Stone of Cold Fire, he's exiled from the Great Valley for several years thanks to his past actions and kidnapping Ducky. However, since he helped save the children, his sentence was lessened significantly.
- HeelFace Turn: In the end, he saves the children and abandons his former ways.
- "I Am Great!" Song: "Very Important Creature", a song where he proclaims that everybody would be better off if he were in charge.
- It's All About Me: His theme song, "Very Important Creature" highlights this. He's motivated by a big superiority complex.
- Jerk with a Heart of Gold: He may be selfish and arrogant, but he's not heartless and has redeemable qualities deep down, as Ducky points out.
- Knight of Cerebus: Thanks to his having gotten a large number of the herd killed, he brings a much more personal threat to the adults of the Great Valley than any villain before him.
- Large Ham: Comes with the territory of being played by Michael York.
- Meaningful Name: Pretty obviously derived from his genus name of Pteranodon
- My God, What Have I Done?: He has this response a lot. Most notable is the one listed directly below. Simply watch his expressions and body language during the fast biter attack.
- My Greatest Failure: 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.
- Nephewism: While hes certainly not above manipulating his nephew for his own ends, he is genuinely just as fond of Petrie as Petrie is of him, and seems to be the closest thing Petrie has to a father figure in the series.
- Never My Fault: His Fatal Flaw. Though as much of an egomaniac he is, it's Played for Drama as it has more to do with his guilt and agony for the raptor massacre he unintentionally led his followers to. He finally manages to overcome it at the end of the movie when he agrees to take responsability for his actions, no matter how horrible the situation is.
- Papa Wolf: When Rinkus slaps his nephew Petrie away while the latter is giving chase and trying to rescue Ducky, Pterano retaliates in kind.Pterano: [strikes Rinkus] If there's one thing I will not tolerate, it's violence!
Rinkus: Then why are you hitting me?
Pterano: Right, make that two things: violence and stupid questions! [strikes Rinkus again]
- Pragmatic Villainy: Played with, as he does genuinely mean no harm to the kids, but he does still point out that doing so would also be inconvenient to his plan.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 (Evil Laugh before being smacked in the face by Pterano)Pterano: Mr. Rinkus, if you threaten the young ones it will put the elders on alert. They will 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!
- Pride: He has a very overinflated opinion of his leadership abilities.
- Ptero Soarer: 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.
- Villain Song: '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.
- Well-Intentioned Extremist: He legitimately believes himself to be a good leader and thinks that everyone would be better off with him as such.
Appear in film seven only.
- Beware the Silly Ones: Rinkus initially seems like a goofy idiot, but turns out to be even more dangerous than Sierra.
- Brains and Brawn: Rinkus is the brains and Sierra is the brawn.
- Dirty Coward: 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.
- Knight of Cerebus: They're much more threatening and less comical than previous villains such as Ozzy and Strut or Ichy and Dil.
- Meaningful Name: Likely comes from phonetic respellings of Cearadactylus and Rhamphorhynchus, their genus names.
- Murder Is the Best Solution:
- Sierra suggests feeding the main characters to sharpteeth.
- Rinkus says that should kill Littlefoot if he doesn't give them information about the stone.
- Not So Harmless: Rinkus, who proves himself to be a pretty nasty schemer on several occasions.
- Obfuscating Stupidity: Underneath his supposed stupidity, Rinkus is easily the smarter and more treacherous of the two.
- Pragmatic Villainy: Rinkus, as opposed to the eccentric Pterano and 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. Of course, he also points out to Sierra that it would be inconvenient for them to just kill Pterano and instead opts to just tolerate him long enough to get power from the Stone of Cold Fire, then dispose of him when he's no longer needed.Rinkus: Just be patient; let HIM lead US to the stone...
- Seldom-Seen Species: Sierra is a Cearadactylus, whose only other appearance in popular media was the novel version of Jurassic Park.
- Shout-Out: Rinkus is constantly twisting his tail in his hands, kind of like a certain other famous cowardly character.
- Smug Snakes: Both of them, but Rinkus moreso than Sierra.
- The Sociopath: They're both this, in different flavors; Sierra's the violent, hateful sociopath with no empathy, while Rinkus is the lying, deceitful sociopath who can convincingly fake emotions and manipulate people.
- The Starscream: They plot to put up with Pterano's self agrandizing ego long enough until he takes them to to the Stone of Cold Fire, where they try to take its supposed power for themselves.
Appear in film seven only.

Charles Kimbrough (male)
Patti Deutsch (female)
- Alien Among Us: 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.
- Catchphrase: "That would be telling, wouldn't it?" usually said in response to the kids asking a question whose answer would reveal too much. In all fairness to the Rainbow Faces, the male one has his Saying Too Much problem.
- Cloud Cuckoo Lander: The Great Valley seems to see them as weirdos who say bizarre things, although Mr. Clubtail claims they seem 'harmless enough'.
- Deadpan Snarker: The female Rainbow Face.
- Like an Old Married Couple: How they generally act. And they might be one, but there's no confirmation.
- The Philosopher: They both bring up points of view that seem alien to the members of the Great Valley, such as the idea that there's nothing that makes the Mysterious Beyond 'mysterious' other than a lack of will to explore it.
- Saying Too Much: 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!
- The Spock: Both are incredibly logical and scientific about the world, and utterly unconcerned with how weird the Valley residents think they are.
Debuted in The Land Before Time VIII: The Big Freeze
Appears in film eight and several TV episodes.
- Voiced by:
Robert Guillame (VIII)
Dorian Harewood (TV series)
- Ascended Extra: Appears in only one film, becomes a regular character in the TV series.
- Break the Haughty: Starts out the film as being very proud of his knowledge and position in the valley, and speaks to Grandpa scathingly about Littlefoot's stream of questions. When he's proven incredibly wrong about the potential of snowfall in the Great Valley, he's shunned by the herd and is forced to accompany the children on their journey to find Ducky and Spike.
- Cool Old Guy: After mellowing out by the end of The Big Freeze he becomes one in the TV show.
- Friendless Background: According to himself he was cripplingly shy as a youngster.
- I Just Want to Be Special: When he was young, Mr. Thicknose was incredibly shy and had difficulty making friends. He often spent his time listening to the things that the farwalkers had to say as they passed through the Great Valley, and it was because of this that he amassed so much second-hand knowledge. His position as a keeper of wisdom in the valley is so precious to him that when he loses it he feels as though he has little else to live for.
- Know-Nothing Know-It-All: 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.
- Spock Speak: Played for Laughs as he explains the various ways of getting leaves to fall from a tree, like the 'Cranio-Impactus Method' that involves hitting the tree with your head.
- Stern Teacher: He dislikes all of the prying questions Littlefoot keeps asking him, to the point that he tells his grandparents that he's a trouble-making influence on the rest of his class. Later, it's revealed he actually thought Littlefoot asked very good questions, but he had been afraid that it might have accidentally revealed that he really hadn't been everywhere and seen everything.
- Wise Old Folk Facade: Downplayed. Although he is not evil, he does pass himself off as an old mentor just so he can get some attention. When snow falls down on the Great Valley and Little Foot reveals that he had told Mr. Thicknose before it happened and that Mr. Thicknose refused to believe him, everybody becomes aware of his lies. He does redeem himself in the end with even Littlefoot referring to him as the oldest and wisest.
- Younger and Hipper: 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.
Appears in film eight and the TV episode The Forbidden Friendship.

Jeremy Suarez (VIII)
Cree Summer (TV series)
- Forbidden Friendship: Hes extremely fond of Spike, and the two of them continue to play together in secret after their parents expressly forbid them from interacting with each other in the TV series.
- Innocently Insensitive: He commits acts of affection with Spike while unaware of how upsetting Ducky finds their bond.
- Keet: Excitable and energetic, he loves playing rough and tumble games with Spike.
- Third-Person Person: In the TV series.
- Suddenly Voiced: He was largely silent in his debut appearance due to his young age, but by the time of the TV series he's learned to speak in broken English.
Debuted in The Land Before Time IX: Journey to Big Water
Appears in film nine, makes cameos in films ten and twelve, and appears in the TV episode The Missing Fastwater Adventure.
- Voiced by:
- Blood Brothers: Sort of. In the ninth film, he and Littlefoot become 'mud brothers', a G-rated equivalent.
- The Cameo: He makes a brief apperance on screen during 'Adventuring' in Great Longneck Migration and 'Flip, Flap, Fly' in Great Day of the Fliers.
- Guest-Star Party Member: Journey to Big Water revolves around the gang trying to guide Mo through the flooded waterways around the Great Valley and back to the rest of his pod in the ocean.
- Heroic Sacrifice: Narrowly escapes a swimming sharptooth when it changes direction while he hides in a hollow log.
- Innocently Insensitive: He can irritate Cera with his pranks and once pretended to get stuck underwater as a practical joke to Littlefoot and the others. He doesn't do it out of malice but under the impression it's good-natured fun.
- Keet: The little guy has tons of energy.
- Meaningful Name: Likely comes from Opthalmosaurus, which is his genus name.
- Starfish Alien: If the Swimming Sharptooth is an Eldritch Abomination 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.
- The Prankster: He loves playing practical jokes on his mud brothers, the most common of which is suddenly spraying them with water or mud.
- Third-Person Person: Overlaps with You No Take Candle. "Mo come from BEEEG water!"
Appears in film nine only.
- Big Bad: Of Journey to Big Water.
- Evil Counterpart: 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.
- Eldritch Abomination: To the kids. They've never seen anything like it, and Littlefoot even calls it a monster.
- Kraken and Leviathan: Of the leviathan type.
- Never Smile at a Crocodile: Not quite, but it's certainly meant to bring this trope to mind
- Non-Malicious Monster: 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 the kids, but it's clear that it is just trying to get home, and it stops antagonizing them after it smells the ocean.
- Non-Standard Character Design: It's probably the most realistically designed creature in the series. Even the more vicious portrayals of sharpteeth in the series has them looking stylized and slightly cartoony, whereas the Sharptooth Swimmer looks like it was plucked straight out of a nature documentary. It also has no pupils or facial expressions (most of the time)
- Sea Monster: Well, it is a Liopleurodon, so what did you expect? It to be eating cheese?
Debuted in The Land Before Time X: The Great Longneck Migration
Appears in films ten, fourteen, and the TV episode The Big Longneck Test.
- Call-Back: Brons explanation of where hes been for all of Littlefoots life provides more callbacks to the original film than at any other point in the sequels (the only other ones being a mention of the earthquake in the seventh film, mentions of Littfoot's mother dying in the fifth and fourteenth films, and some throwaway callbacks in the second, thirteenth, and fourteenth films). Among them is the only ever direct mention of the original Sharptooth to date.
- Disappeared Dad: He left to find a suitable place to live before Littlefoot's birth and by the time he returned, the Great Earthshake had occurred.
- Distressed Dude: In Journey of the Brave, Bron gets trapped by lava while trying to save Wild Arms from his own clumsiness during an eruption at Fire Mountain. The events of the film revolve around Littlefoot setting out on a mission to find his father and rescue him.
- Good Parents: 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.
- I Thought You Were Dead: Bron's excuse for having never met his son until now.
- Lightning Bruiser: 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.
- Like Father, Like Son: 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. Oh, and there's also the fact that they both fought Sharpteeth and won.
- Meaningful Name: Likely comes from Brontosaurus, a genus commonly mistaken for Apatosaurus.
- Named Like My Name: 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.
- Reality Ensues: Sorry, Bron, your son is not going to instantly accept you when he finds out you're his father. Indeed, Bron ends up having to explain, in detail, where he was for all that time and why he was never there for him to get Littlefoot to forgive him.
- Remember the New Guy?: He somehow already knows who Chomper and Ruby are in the TV series, despite it never being shown how they were introduced, or how Bron reacted when he found out that one of his sons best friends is the same kind of creature that killed his wife.
- No One Gets Left Behind: Bron would risk his life for anyone in his herd— even for weirdos like Wild Arms.
- One-Hit KO: 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, where Sharpteeth are concerned.
- Parental Substitute: To Shorty.
- Starting a New Life: The events of the first film more or less completely destroyed Bron's old life, as it left his wife dead, his old home in ruins, and the whereabouts of his child unknown. While trying to find some sign of the child that had been born while he was looking for a place for his family to live, he runs across Shorty, which leads him on a path to a new life as a herd leader.
Appears in film ten and the TV episode The Big Longneck Test.
- Voiced by:
Brandon Michael de Paul (X)
Elizabeth Daily (TV series)
- Big Brother Bully: When he first meets Littlefoot, his future step-brother, he picks on him. This tendency abates once Bron agrees to adopt Shorty.
- Brats with Slingshots: He uses his tail to smack pebbles at things with great precision.
- Calling Parents by Their Name: Even after Bron officially adopts him and becomes his father, Shorty still continues to call him Bron, and when talking to Littlefoot refers to him as 'your dad'.
- Green-Eyed Monster: Shorty is blisteringly jealous of Littlefoot hogging all of Bron's attention, to the point that he tries to start physical confrontations with him.
- Happily Adopted: By Bron.
- Leader Wannabe: 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 foster brother's leadership talents.
- No Place for Me There: While Bron is understandably ecstatic to have found the son hed thought hed lost long ago, Shorty sees it as Bron finding his family and no longer having need for him, just like how his old companions left him when they found their own families after the events of the original film. Shorty prepares to slip away when Bron isnt noticing, but Littlefoot stops him and tells him that Bron still cares for him, even bringing up the possibility of the two being brothers now.
- Not So Different: He and Littlefoot were in identical situations following the earthshake of the first film: both are separated from their family and must team up with other youngsters to survive. However, as he and his companions start following Bron, one by one they're all reunited with their family members— except for Shorty.
- Street Urchin: Not unlike Littlefoot himself, Shorty was left alone to fend for himself after the Great Earthshake of the first film. However, unlike Littlefoot, Shorty never reunited with anything he could call family.
- What Happened to the Mouse?: Is neither seen nor mentioned in Journey of the Brave, despite the plot revolving entirely around finding Bron and the arrival of his herd.
- Voiced by: James Garner
- Agony of the Feet: The poor guy gets his foot burned by lava.
- Meaningful Name: Likely comes from Apatosaurus, his genus.
- What Happened to the Mouse?: He hasn't reappeared since the tenth film, despite deciding to come to the Great Valley with the others.
Debuted in The Land Before Time XI: Invasion of the Tinysauruses
They appear in film eleven and make a cameo appearance in film twelve.
- Badass Baritone: The leader of the tinysauruses, Big Daddy, is voiced by Michael Clarke Duncan.
- Beneath the Earth: They initially hide in the caves underneath the Great Valley to avoid persecution from larger dinosaurs. According to Ducky in Stranger from the Mysterious Above they still live in the valley caves by the time of the TV series, despite not having any reason to hide anymore.
- Call a Rabbit a "Smeerp": Despite it being in the title of the eleventh movie and the term theyre most widely know by, theyre never actually called Tinysauruses in the film, and instead called little longnecks. However, in an episode of the TV series Ducky does refer to them as such.
- The Cameo: Several Tinysauruses briefly appear during a subterranean sequence in the song 'Flip, Flap, Fly' in Great Day of the Fliers.
- Informed Species: While Mussaurus were sauropodomorphs and an early relative to proper sauropods, they weren't actual sauropods themselves and had a body structure that differed in many ways from the typical sauropod body shape they're shown having in this film, most notably the fact that they were believed to be capable of bipedal locomotion as adults.
- Lantern Jaw of Justice: Big Daddy has a very prominent chin.
- Little People: They're the smallest dinosaurs in the series, with the adults being even smaller than Ducky. Justified, as juvenile Mussaurus were indeed incredibly tiny (hence the name 'Mouse Lizard'), although in real life the adults got much bigger than how they're depicted here.
- The Scapegoat: Littlefoot blames them for eating all the tree sweets off a special tree, which is half-true but ignoring how they couldnt have done so without him accidentally knocking them all down. Partly because of his own initial fear of them, Littlefoot doesnt realize how much trouble this causes for the tinysauruses until he gets to know some of them personally. As it turns out, getting unfairly blamed for misfortunes is something that happens to them wherever they go.
- Science Marches On: Since their discovery in the 1970s, Mussaurus were only known by juvenile specimens and their size shown in Invasion of the Tinysauruses wasn't inaccurate with what was known at the time. A few years later, however, adult Mussaurus fossils were found and were much larger than the juvenile specimens that gave the genus its name, making the films depiction of them inaccurate in hindsight.
- Vocal Dissonance: Big Daddy is a tiny dinosaur with a deep, booming voice provided by Michael Clarke Duncan.
- Walking the Earth: Everywhere they go theyre treated like vermin, and travel from place to place to try to find somewhere they can call home. At first it seems as though the Great Valley is just as prejudiced towards them as anywhere else, but by the end of the film they elect to settle and become valley residents.
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 Cera's half-sister, Tricia. 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.

- Brooding Boy, Gentle Girl: The gentle girl to Topsy's brooding boy.
- Death Glare: Gives an absolutely livid one to Mr. Threehorn when she realizes he played a big part in making the Tinysauruses seem far more dangerous than they actually were to the rest of the valley and nearly getting them killed in the process.
- Good Parents: She's a good parent to her biological daughter and a good stepparent to her stepdaughter.
- Mama Bear: In the final act of Invasion of the Tinysauruses she aggressively defends Cera from a group of fast biters, despite the two having being on rocky terms with each other for most of the film.
- Minnesota Nice: In the TV series, at least. There are hints of the accent in her inflections, and she certainly has the polite behavior.
- Morality Pet: She seems to be the only adult in the series capable of soothing Cera's hot-headed father.
- New Old Flame: To Topsy.
- Open-Minded Parent: Unlike Topsy, Tria never displays any speciesist tendencies and is nothing but polite and welcoming to Cera's non-threehorn friends, even to Chomper who her husband has displayed a regular fondness for tormenting.
- Wicked Stepmother: Averted. When she first gets together with Topsy, she takes great pains to try to establish a healthy, loving relationship with Cera, who's unwilling to facilitate it at first. Tria's patience eventually runs out and the two clash briefly, but Cera decides to give her a chance. After that, she loves and cares for Cera like she's her own daughter.
Debuted in The Land Before Time XII: The Great Day of the Flyers
Appears in film twelve and the TV episode The Hermit of Black Rock.
- Voiced by: Rob Paulsen
- Adorkable: His nervous, awkward nature makes him quite lovable.
- Informed Species: Even by the standards of the series he is stylized as hell, resembling more or an odd Oviraptor-muppet than the thing he's supposed to be.
- Instant Expert: Has no problem flying, as long as he is asleep. Later learns to do it for himself.
- Joisey: He possesses a mild New Jersey accent.
- Last of His Kind: Allegedly, likely stemming from...
- Laser-Guided Amnesia: 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...
- No Celebrities Were Harmed: A pretty obvious Woody Allen parody.
- Noodle Incident: Chomper mentions that the two were first introduced when Guido baby sat for Tricia, which is why he's only nervous when he sees him instead of outright terrified.
- Remembered I Could Fly: See above, and only after everyone tells him he can.
- Plucky Comic Relief: Like Petrie, he's a panic-prone flier whose fears are often Played for Laughs.
- Science Marches On: Since the coloration of almost all dinosaurs is unknown, Guidos teal feather colors were in the realm speculative artistic license by the time of film twelve, just like the colors of pretty much every other creature in the series. However, a few years after Great Day of the Flyers, new analytical techniques resulted in the discovery of what color Microraptors plumage actually was: glossy iridescent black, not teal.
- Toothy Bird: Inverted; Microraptors had toothy snouts in real life, but Guido has a toothless, parrot-like beak.
- Vegetarian Carnivore: Subverted. He doesn't know what kind of animal he is, so it takes a while for him to figure out his real diet. He starts out trying to eat leaves, but he's grossed out by them. He instead eats a bug that he found on one of those leaves...and he instantly loves it. His friends are kind of squicked out by this.
Appears in films twelve, as well as multiple TV episodes.
- Voiced by:
Nika Futterman (XII)
Meghan Strange (TV series)
- Baby Talk: She's too young to talk, although she's already said her first word: 'Cera'.
- Big Brother Worship: Cera is the very first thing Tricia ever sees, and as such she takes an immediate liking to her big half-sister. In fact, she's so fond of Cera that she seems more willing to devote her attention to her than to their parents.
- Cheerful Child: She seems to take heavily after her mother's warm, sunny personality, and is rarely seen without a giggle or a smile.
- Fearless Infant: Not unlike her older nephew and niece Dana and Dinah, Tricia easily gets into danger and often needs her big sister or her parents to keep a close eye on her and bail her out of trouble.
- Named Like My Name: Her name is very similar to her mother's.
- Ridiculously Cute Critter: Being a little Triceratops hatchling, how can she not be?
- Sibling Rivalry: Cera was none too keen of Tricia when she was first hatched, as she hogged all of her father's and Tria's attention. By the end of film twelve, however, Cera grew to love her new half-sister, and future installments almost always show them on good terms with each other.
- Sibling Yin-Yang: While Cera is grumpy, short-tempered, and aggressive like her father, Tricia is bubbly, exuberant, and playful like Tria.
Debuted in The Land Before Time XIII: The Wisdom of Friends
Appear only in film thirteen.
- Call a Rabbit a "Smeerp": They're referred to as "Yellow Bellies".
- Does This Remind You of Anything?: Doofa has a habit of calling Cera beautiful. That combined with picking her up the first time they meet, well...
- Escort Mission: 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 Adults Are Useless, or perhaps more aptly, Adults Are Helpless.
- Inexplicably Tailless: They do not have a tail but instead a ponytail of feathers.
- Informed Species: They don't bare very much resemblance to the real Beipiasaurus. They almost don't even look like actual dinosaurs!
- Seldom-Seen Species: Not often you see therizinosaurs in cartoons, let alone Beipiaosaurus.
Debuted in The Land Before Time XIV: Journey of the Brave
Appears in film fourteen.
- Voiced by: Damon Wayans Jr.
- Adorkable: His nervous yet theatrical nature makes him this.
- Butt-Monkey: He's rarely shown in a dignified position.
- Cloud Cuckoo Lander: He didn't even realize the origin of his name until he seemingly realized it in the middle of his conversation with Mr. Threehorn.
- Fainting: He's terrified of Chomper the moment he sees him, and as soon as the boy goes in to hold his hand to guide where he's going, he faints on the spot.
- The Fool: He seems sheepishly aware of how foolish he comes across to people, and simply cant help that he annoys people, scares easily, and is a massive klutz. Even his attempts to try make himself look a bit more dignified end with him all but admitting that he knows hes not fooling anyone.
- Guest-Star Party Member: Not for the gang, but for Mr. Threehorn and Grandpa Longneck as they trail Littlefoot.
- Hate at First Sight: A one sided version. Topsy dislikes him the moment he sets eyes on him. Wild Arms is intimidated by Mr. Threehorn, but does try to get into his good graces as the film goes on.
- The Klutz: He has, to put it mildly, a striking lack of grace, and often flails his arms around wildly when he's running about. It's this clumsiness that ends up putting Bron in danger as he stays behind to rescue him.
- Lovable Coward: He constantly suggests going back to the Great Valley instead of going to save Bron, and is so terrified of Chomper— a kid who's less than half his size— that he faints when he so much as touches him.
- Miles Gloriosus: He'll often retell stories in a way that paints him in a better light than how it actually happened, although absolutely no one is fooled by this.
- The Millstone: A light example: other than giving directions hes often more work than hes worth to the rescue group consisting of Grandpa Longneck, Mr. Threehorn, Chomper, and Ruby. However he doesnt seem to slow them very much as even when he faints from Chomper touching his arm Mr. Threehorn simply lugs him over his shoulder and comments how he knew hed end up having to carry him.
- Only Known by Their Nickname: 'Wild Arms' is a name that everyone has assigned him because of his wild, colorful arms, and as such it isn't his actual name. In fact, he didn't even realize what it was referring to until recently.
- Pinch Me: At least until he sees that the nearest person is an unamused Mr. Threehorn glaring daggers at him—then he just pinches himself.
- Seldom-Seen Species: Before Wild Arms, Nothronychus only appeared in dinosaur documentaries.
- Small, Annoying Creature: It's clear that the other adults find him very hard to put up with because of his loud, talkative, cowardly nature, which is especially true for Mr. Threehorn who's almost always seen glaring at him.
A flier who's a member of Bron's herd, and is separated from everyone else by the eruption of fire mountain. She travels with the rest of Bron's herd.
- Voiced by: Reba McEntire
- Analogy Backfire: Almost every uplifting metaphor that comes out of her mouth is followed by a down-beat aside that kills any hopeful effect she was going for.
- Animal Gender-Bender: She is tall and has a long crest like a male Pteranodon. Gets jarring in that the franchise already had Petrie's mother, who is an accurately-portrayed female Pteranodon.
- Call a Rabbit a "Smeerp": She's specified as a 'Big Beak' subtype of flyer.
- Cloud Cuckoo Lander: Her way of thinking is odd to say the least. She also has the habit of telling morbid stories.
- Cool Old Lady: She's significantly older than the main cast, but still optimistic and hopeful. When Littlefoot is beating himself up over getting his friends into a situation too big for them to handle, she tries her best to cheer him up.
- Ink-Suit Actor: She has Reba McEntire's green eyes and long eyelashes, as well as a red tinge on her crest that's the same color as Reba's hair.
- Non-Standard Character Design: She looks completely different than the other Pteranodon in the series, not even bearing the slightest resemblance to Petrie.
- Ptero Soarer: Even has a green scaly skin to boot, while the other pterosaurs in the series at least get shading that implies furry coats.
- Rambling Old Man Monologue: She has plenty of stories about her family that she loves to bring up, and most of them end morbidly.
- Southern Belle: Etta retains her voice actress's pronounced southern drawl in the film.
- Suspiciously Similar Substitute: For Archie from film four, another old cave dweller who helped Littlefoot when he was separated from his friends because of a cave-in, and Swooper from the TV series, whos also a cave dwelling old flier with a southern accent and a few screws loose.
- Team Mom: She's very affectionate towards Littlefoot in particular, which might be due to the fact that he's her herd leader's son.
- Big Bad Duumvirate: Of the first half of the fourteenth film.
- Feathered Fiend: By virtue of being the largest known feathered carnivorous dinosaur.
- Four-Fingered Hands: Inverted; Yutyrannus has three fingers per hand, but these guys have four fingers.
- Non-Standard Character Design: Unlike the other sharpteeth, they have their antorbital fenestra faintly visible. Also a case of Artistic License Paleontology as this is a process known as "shrink-wrapping".
- Seldom-Seen Species: This is the first time the "feathered tyrant" appears in animation.
- What Could Have Been: According to an interview with one of the film's animators, they were apparently planned to be Allosaurus at some point.
- What Happened to the Mouse?: Chomper, Ruby, Wild Arms, Grandpa Longneck, and Topps never encounter them as they pass through their territory (at least not on-screen).
- Informed Species: They're extremely stylized even by the standards of the series and also much smaller than Oryctodromeus were capable of getting, being shown to be roughly the size of Petrie in Journey of the Brave when in reality they could grow up to two meters long and a little under a meter tall.
- Instant Fan Club: After Petrie unintentionally helps them retrieve some fruit from a tree they treat him like he's practically royalty. They're also shown to do this to pretty much anyone who helps them get food, as shown when they immediately crown someone else their new leader as Petrie is leaving just for accidentally knocking down a few pieces of fruit.
- Seldom-Seen Species: Burrowing dinosaurs, let alone small ornithopods, rarely show in fiction.
- You No Take Candle: They seem to only speak a very broken form of the leafeater language, possibly due to their implied omnivorous diet.
- Artistic License Paleontology: Both its horns and forelimbs are too long and facing forwards.
- Attention Deficit... Ooh, Shiny!: In his second scene, while suspicious that the rescue group of Grandpa Longneck, Mr. Threehorn, Chomper, Ruby, and Wildarms is in the area, he spots a herd of Ornithomimidae and chases them off, leaving the film.
- Big Bad: Of the second half of the fourteenth film.
- Darker and Edgier: Noticeably more vicious and relentless than the Featherhead Sharpteeth and without any moments of comedy to give it levity.
- Four-Fingered Hands: Carnotaurus actually did have four fingers, but the one here has only three. Although in some shots it is shown with the accurate four fingers.
- Non-Standard Character Design: Like the featherhead sharpteeth, it too has a shrink-wrapped skull.
- Stock Audio Clip: Many of his roars come from the audio of one of the bosses from the Lost World: Jurassic Park light gun arcade cabinet. Ironically, it uses the T. Rex's audio, even though a Carnotaurus boss exists in the game.
