->'''Lex:''' Sh. Sh. Don't let the monsters come over here.
->'''Dr. Alan Grant:''' They're not monsters, Lex. They're just animals. And these are herbivores.
->'''Tim:''' That means they only eat vegetables, but for you I think they'd make an exception.

This trope, along with PredatorsAreMean, are by far the most common approach to CarnivoreConfusion in fiction. Basically, all the villains are carnivores and all the herbivores, particularly if [[TalkingAnimal they can talk]], are heroes.

Like PredatorsAreMean, this trope has been around for such a long time that it may be one of TheOldestOnesInTheBook. Herbivores Are Friendly often, but not always goes hand-in-hand with PredatorsAreMean.

This trope and PredatorsAreMean are so strong culturally that people assume that many RealLife predators (whether omnivorous or carnivorous by nature) are mean, evil, and nasty, and all the herbivores are cute, cuddly, and friendly!

This is [[TelevisionIsTryingToKillUs not true for the most part]]. For example, the [[CuteKitten common house cat]], one of the world's most popular pets, is carnivorous and the harmless whale shark, the gentlest of all sharks, is omnivorous. Inversely, the big herbivores are some of the most dangerous, surliest animals; [[KillerRabbit the loveable hippo and elephant]] are known for attacking and killing humans (even) without being provoked. In other words just because an animal won't ''eat'' you, doesn't mean it won't ''hurt'' you.

For example, Film/TempleGrandin's book ''Animals in Translation'' shows that, surprisingly, even the huge, social, herbivorous domestic cow can be more dangerous to handle than the large, largely solitary, predatory tiger is. A cow or bull can attack a person out of dominance, but a tiger won't because they don't care about constant jostling within a social hierarchy. You obviously have to be ''extremely'' careful not to trigger any big cat's prey drive, but there isn't any dominance aggression.

One common exception for the herbivores, when they are portrayed as dangerous in fiction, is when they go on an AnimalStampede.

Sometimes, the nice, friendly herbivore is actually a VegetarianCarnivore.

Goes hand-in-hand with and opposite of PredatorsAreMean. Often associated with CarnivoreConfusion. Subtrope to GoodAnimalsEvilAnimals and AlwaysLawfulGood.



[[folder:Anime and Manga]]
* [[Manga/LuckyStar Tsukasa]] learned the hard way that when deer want her biscuits, they get the biscuits. [[https://www.youtube.com/watch?v=-BsWBqWBhV0 Regardless of what she has to say.]]
* When [[Manga/CageOfEden Segawa]] encounters a [[http://en.m.wikipedia.org/wiki/Chalicotherium Chalicotherium]], she thinks that because it's an herbivore, she should be safe. She is quickly proven wrong.


[[folder: Comic Books]]
* ''ComicBook/AtomicRobo'': Zig-zagged in "The Trial of Atomic Robo". Doctor Dinosaur's latest killing machine is the "omnisaur" -- half ''Triceratops'', half ''Ankylosaurus'' and [[TooManyHalves half]] ''Stegosaurus''. Robo points out that those are all herbivores.
-->'''Dr Dinosaur:''' Herbivores. What was I thinking? Oh, right! The super-beams!\\
'''Robo:''' The what? ''[omnisaur starts glowing]''

[[folder:Film -- Animated]]
* The main dinosaur characters from ''WesternAnimation/TheLandBeforeTime''. Chomper the friendly [[TyrannosaurusRex Sharptooth]] is an exception.
* Often averted and subverted with the recurring buffalo in the ''WesternAnimation/KungFuPanda'' movies and TV series. Played straight with the recurring rabbits though.
* In ''Disney/SnowWhiteAndTheSevenDwarfs'', Snow White has deer, rabbits, squirrels, songbirds, and a [[TurtlePower tortoise]] helping her work.
* In ''WesternAnimation/AnAmericanTail'', Tiger, a VegetarianCarnivore, is the only nice cat in the film. He befriends Fievel, a mouse, after confessing that his favorite food is broccoli.
* Unlike most sharks, Lenny from ''WesternAnimation/SharkTale'' is actually a vegetarian and is also pretty friendly since he doesn't want to hurt other fish. That doesn't stop the fish from being scared of him though.
** He also tries to befriend the other fish by masquerading as a dolphin. Dolphins are carnivores too. (They're also a great deal nastier than most people would believe, as they routinely conduct rape, sexual coercion, and pleasure killing.)
* Another dinosaur example is the movie ''Disney/{{Dinosaur}}''. The main characters are all herbivores, and even the mean herbivore rivals are only trying to accomplish the greater good.
* Inverted in ''WesternAnimation/ABugsLife''. The grasshoppers (herbivorous insects) are villains and the ants (omnivorous insects) are good.
* Definitely averted in ''Disney/{{Zootopia}}'', where "prey" animals are just as likely to be mean as "predator" animals, as seen with the blunt, aloof, and harsh buffalo, [[DaChief Chief Bogo]]; the angry and prejudiced elephant, Jerry Jumbeaux Jr.; and Doug the ram, who is described by Duke Weaselton as "the opposite of friendly."

[[folder:Film -- Live Action]]
* Film/{{Mothra}} is among the most peaceful of all kaiju and happens to be a nectar-feeding butterfly/moth. So long as you don't [[BerserkButton kidnap Her fairy companions]] or [[MamaBear harm Her children in any way]] She won't hurt you. And if you ''do'', you'll find that [[MamaBear She wrecks cities as well as any Kaiju]].
* A subversion occurs with Franchise/{{Godzilla}} Junior. Though he is shown eating leaves in ''Film/GodzillaVsMechagodzillaII'', his species is actually carnivorous. Though, compared to his more aggressive father, he is quite friendly.
* ''Franchise/JurassicPark'':
** In ''Film/JurassicPark'', Dr. Grant calms Alex down when she sees nearby ''Brachiosaurus'' by reassuring her that they're plant-eaters.
-->'''Tim:''' Veggie-sauruses!
** ''Film/TheLostWorldJurassicPark'' averts this, as the ''Stegosaurus'' are ''very'' dangerous when they think someone is messing with their infant, or the ''Pachycephalosaurus'', which rams a few people straight ''through'' a Jeep with its head. The [=InGen=] camp is also torn apart largely by herbivorous dinosaurs released from their cages.
** The ''Film/JurassicWorld'' website lists almost all of its herbivores as having low aggression, with the exception of the armor-plated ''Ankylosaurus'', whose aggression is listed as "medium". [[InvokedTrope Then again, they may have been gene-designed to be more docile to comply with visitor expectations.]]
* "'

[[folder:Live-Action TV]]
* The herbivore dinosaurs in ''Series/TerraNova'' are shown to be playful in the pilot episode. The main character's youngest daughter even feeds them treats.
* Averted on ''Series/TheJeffCorwinExperience''. Jeff frequently pointed out to viewers that large herbivores, such as elephants and hippos, are far more likely to kill you than the most feared of African predators.
* Notably averted in ''Series/AnimalFaceOff''. While it seems that all PredatorsAreMean on the show, the elephant, rhino, hippo, and gorilla aren't any more pleasant.

* Brian Jaques's ''Literature/{{Redwall}}'' series often shows this. Squirrels (not entirely herbivorous), hares, and other herbivores, and a few omnivores such as badgers, mice, and hedgehogs, are the heroes, where wholly carnivorous species such as weasels, stoats, wild cats, snakes, hawks, ferrets, foxes (actually omnivorous, but still predatory), and the like are the villains. This is rather odd considering the fact that the most prominent species, the mice of Redwall, are omnivores but never eat any meat besides fish. One would reason that they never eat any intelligent creatures, but there has been at least one intelligent talking fish in the series.
* Averted and discussed in ''Literature/LifeOfPi'' when Pi's zookeeper father gives Pi and Ravi an {{Anvilicious}} lesson that all of the animals in the zoo are dangerous, even the herbivores. He concludes the lesson with a straight example by letting them play with the harmless guinea pigs.
* Averted in the original ''Literature/TheJungleBook'' (not the [[Franchise/DisneyAnimatedCanon Disney]] version). The elephant Hathi was an aggressive elephant, who once destroyed a village in revenge. Mowgli then persuades him to do the same in the human village, because Buldeo threatened to kill Messua and her husband, Mowgli's human foster parents.
* Averted in ''Literature/WatershipDown'' with rabbits, as many of them are aggressive and will rip each other apart in a fight.
* Averted in Creator/LarryNiven's ''Literature/KnownSpace'' series. Puppeteers are descended from skittish herd animals, and while this means that they're personally {{Dirty Coward}}s, it also means that they're deceitful, paranoid and xenophobic. The carnivorous Kzinti hold this as a belief; herbivorous animals are inherently weak and stupid. After all, "you don't need brains to sneak up on a leaf!" This belief has backfired spectacularly in their faces on many occasions, such as the "plant giants" of Ringworld, [[HumansAreWarriors humans]], and the previously mentioned Puppeteers.
* Discussed in ''[[Literature/PrinceRoger March Upcountry]]'': Captain Pahner sees a large herbivore on an unfamiliar planet and tells his troops not to fire. Prince Roger shoots the thing anyway, because he has actually been on safari and knows that herbivores are not harmless (and because he hadn't figured out the com software yet and hadn't heard the order).
* ''Literature/TunnelInTheSky'' averts this. Rod sees a herd of antelope-like herbivores but keeps his distance knowing that a herd with hooves and horns is still dangerous.
* Played around with in ''{{Literature/Dinoverse}}''. In the first set of books, the ''Leptoceratopses'' abduct Candayce and shove Janine around, and Candayce figures out that they were trying to protect her - she's in the body of a ''Leptoceratops'' and they don't understand why she's hanging out with a ''TyrannosaurusRex''. Similarly, when they encounter a ''Triceratops'' herd, it is hostile in defense of its nests, but is less so later, realizing that a little ''Leptoceratops'' and a wounded ''[[PteroSoarer Quetzalcoatlus]]'' aren't threats. The ''Ankylosaurus'' met later on is friendly to the boy in the ''Ankylosaurus'' body, but wary at best of all the others.
* ''Literature/RaptorRed'' averts this one. The main viewpoint characters are carnivores, and they have to work ''hard'' for their meals against wary and violent prey. Some herbivores they won't even touch outside of extremely unusual circumstances because of how good their defenses are. And woe betide the predator who encounters an unknown herbivore who doesn't fear them: it usually means they have a deadly trick the carnivore doesn't know about until it's too late.
* Averted when time gets shattered in ''Discworld/ThiefOfTime'': both the hippo that confronts Susan and the mammoth that confronts Lu-Tze are described as dangerous, just not ''quite'' as dangerous as the humans involved.
* Discussed and averted in ''Last Chance To See'' by Creator/DouglasAdams, which in addition to the obvious big mammals, notes that the wild animal that kills most people in Africa is the ''ostrich''.
* The [[TheReptilians Hork-Bajir]] from the ''Literature/{{Animorphs}}'' series are, when free from [[PuppeteerParasite Yeerk]] control, naturally docile and unintelligent creatures who use the numerous blades on their bodies to strip bark from trees for food. A community of Hork-Bajir who escape the Yeerks become close allies of the Animorphs.
* In ''Literature/EdenGreen'', needle monsters from another dimension invade an Arkansas city. Most are predators, but at least one species is herbivorous and forms into harmless herds when left alone. However, when spooked, they form dangerous stampedes, and the 'bulls' are territorial and potentially dangerous.
* In her [[http://www.twilightlexicon.com/2007/05/20/personal-correspondence-12/ Personal Correspondence 12]], Creator/StephenieMeyer appears to think this. She uses cattle and rabbits being killed by farmers as a comparison to how powerless humans are against the vampires of ''Literature/{{Twilight}}''.
--> Let’s go with the herd of cows analogy. Let’s say these cows are aware Farmer Bob is slaughtering cows in his slaughterhouse. What can they do? They don’t have the physical ability to track him in his world and punish him. Maybe, if they’re really lucky, they can catch him off guard without his gun or truck and trample him. But in that scenario, cows representing humanity actually makes them more powerful than is correct. It would be more like bunnies [...] So you’ve got a bunch of rabbits being killed whenever Farmer Bob is in the mood for rabbit stew. What can they do to bring him to justice? Answer: nada.

[[folder:Myth and Religion]]
* Some Christian sects in the United States, such as those behind the Creation Museum (Answers in Genesis) believe that this was the literal truth. All animals before the Fall were friendly herbivores, with one diorama showing a ''T. rex'' chomping on pineapples and another section allowing visitors to pose on a large, saddled model of a ''Triceratops''. Likewise, the group maintains no animals were venomous before the Fall. The Texas-based Creation Evidence Museum believes the pre-Fall atmosphere made creatures live longer, made them more intelligent, and made them nicer. Commentary regarding their beliefs is probably subject to the RuleOfCautiousEditingJudgment.

[[folder:Video Games]]
* Played straight and averted in the ''VideoGame/MonsterHunter'' series. Most herbivores, like Aptonoths, really are friendly and peaceful. Herbivore bossmonsters like Diablos? [[PunchedAcrossTheRoom Not so much]].
* Inverted and played straight in ''VideoGame/DinosaurKing'' where while the heroes normally use herbivorous dinosaurs, one exception is a ''Carnotaurus''.
* Subverted in ''VideoGame/DinoSystem'' Unless attacked, most herbivores are usually quite placid and ignore the player. Which can make it all the more surprising during survivor mode when a calm male ''Triceratops'' enters breeding condition and suddenly starts trying to kill the human survivor.
* ''VideoGame/{{Spore}}'' has creatures evolving. The first two stages (Cell and Creature) are spent deciding on a creature's diet. Later stages have the creatures evolved more, with their own moralities. Herbivores tend to be nice and social, carnivores tend to be hostile, while omnivores tend to be neutral and economic.
* Subverted in ''VideoGame/FarCry3'' and ''VideoGame/FarCry4''. ''3'' has water buffalo that generally keep to themselves, but if you walk through their territory, they'll most likely chase you down and try to ram you. ''4'' has yaks which are pretty much just reskins of ''3'''s water buffalo, as well as rhinos and elephants. The rhinos basically act the same way as the yaks, only they're faster, tougher, and do a lot more damage. The elephants, on the other hand, will not bother you at all unless you attack them -- they'll even let you ride them, provided you have the necessary perk. However, once provoked, these elephants are ''very'' dangerous -- and you can use this to your advantage, pitting them against your enemies and even riding them into battle.
** Despite the subversion in ''Far Cry 3'', the binoculars identify animals as herbivore and predator, giving a clear distinction on which animals can attack. The identification is based on whether or not they're aggressive as opposed to their actual diet (e.g. Buffalo are tagged as predators.)
* Mammoths in ''VideoGame/TheElderScrollsVSkyrim'' are mostly peaceful, just don't annoy them or their giant owners. Otherwise, it's played very straight: bears will attack you on sight; deer (which are covered on Real Life) flee from you on sight. Unless, of course, you have any active buff preventing animals from reacting to your presence.
* Averted with the gurns, druffalo and brontos in ''VideoGame/DragonAgeInquisition.'' They won't attacked if they aren't provoked, but they'll fight tooth and nail if wounded.

* ''Webcomic/KevinAndKell'' likes to subvert this often. Kevin and Kell's daughter is a rabbit that eats meat. Kevin himself is generally friendly, but is not above punching predators trying to eat him. In fact, for a mini-arc it ended up a problem for Kevin as one of predators sued him for "breach of nature, rabbits should run". [[spoiler:And was retorted "[[HoistByHisOwnPetard breach of nature]], predators should eat rather than sue".]] And it should be pointed out that Kevin's ex Angelique, genetically a rabbit (but posing as a rat), is one of the most vicious characters in the comic.
* Subverted in ''Webcomic/{{Freefall}}''; Sam's BizarreAlienBiology is edible and appetizing even to Terran herbivores.
* [[http://thepunchlineismachismo.com/archives/comic/when-herbivores-attack Averted]] by ''Webcomic/ManlyGuysDoingManlyThings'' ... line-of-sight is an important thing to consider when around large animals.

* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' pretty much everyone's a herbivore of some sort. This is pointed out in "Over a Barrel" when Pinkie Pie tries using it to create some common ground between some settler ponies and buffalo.
-->'''Pinkie Pie:''' Both our diets, I should mention\\
Are completely vegetarian\\
We both eat hay and oats\\
Why be at each others' throats?
** Spike the gem-eating dragon also gets a pass for [[EatDirtCheap being a lithovore]], as it's not herbivory, but not carnivory either.
** Interestingly, in the opening of the episode "Dragonshy", FriendToAllLivingThings Fluttershy is shown feeding some otters (ferrets?) with fish, as well as giving worms to birds. While some fans think this contrasts with her character, others argue that being so close to nature means that she accepts the necessity of the circle of life.
*** There's actually some people in real life who do this, as well -- some strict vegetarians will still keep carnivorous pets even knowing that their food was made from animals (though others try to force a vegetarian diet on said pets, which can very easily go wrong).
** Crops up in the fandom more generally with the often seemingly inherent assumption that as plant-eating social animals ponies are intrinsically less aggressive or warlike, even though posturing and fighting for position and resources are as endemic to equines as most other social animals (humans included).
** A few episodes show that the ponies still have their share of jerks and bullies.
** Ponies are technically omnivores; in "Applebuck Season," Pinkie Pie mentions eggs, and in "Sisterhooves Social," Rarity makes fried eggs. By some definitions, they still qualify as vegetarian, but not as herbivorous. There's also the question of why pigs are raised.
* Something was said about this in the ''Literature/MagicSchoolBus'' episode where they went back in time and saw dinosaurs.
* ''WesternAnimation/TheWildThornberrys'' plays it straight and averts it. Eliza easily makes friends with plenty of herbivorous animals, but she also encounters some aggressive ones as well, such as hippos and water buffalo which are true.
* ''WesternAnimation/TheSimpsons'' often subvert this trope quite realistically. For example, in one episode Lisa tried to approach a herd of deer because they look harmless, but when she gets close enough they turn ferocious and try to attack her.
** Lampshaded in "Four Women and a Manicure" when the Wicked Witch of Snow White mocks a group of cute woodlands critters, most of which are herbivores. [[CurbStompBattle The critters proceed to gang up and tear the witch apart as she screams in agony.]]
** Doubly subverted in a school video starring Troy [=McClure=],[[note]]you might remember from such videos as “2-3=Negative Fun” and “Firecrackers: The Silent Killer”[[/note]] where he convinces Bobby[[note]]Jimmy[[/note]] that it’s okay to eat meat. [=McClure=] warns Jimmy that “if a cow had the chance he’d eat you and everyone you care about,” as ominous music plays and the camera zooms in on a cow’s face. However, the cow’s face is so placid, that the idea of a threatening cow seems ludicrous.

* RealLife aversion: the vast overwhelming majority of unprovoked [[FeatheredFiend bird]] attacks on people are from herbivorous birds like swans, pheasants, geese, ostriches, and, most famous of all, the [almost entirely frugivorous] cassowary. Hell, if one considers the few annecdotes about eagles killing people to be fictional, all incidents of human deaths by avians are from herbivorous birds.
* Often averted. Many large herbivores are extremely territorial and will kill you deader than dead. The hippo (which, by the way, is more dangerous to humans than the predatory crocodile), the elephant, the rhino, and the cape buffalo are all among the most dangerous animals of Africa. Giraffes have been known to kill lions with their kicks.[[note]]Claims they can decapitate lions is based on a very broad definition of the term where the cranium is detached from the spine as a result of the force of the kicks -- the damage is strictly internal; contrary to popular belief the heads therefore do not become physically separated from the body.[[/note]]
** In captivity, elephants in particular remain dangerous due to sheer size. Even an elephant that ''is'' friendly can easily kill its handler through mere clumsiness, and when a captive elephant loses its temper or panics, whole cars can get thrown aside or crushed by its bulk and muscle-power.
* RealLife Subversion: Herbivores (like cattle) tend to be seen as meat-slaves by humans. Cats and dogs, which are the animals most commonly seen as family members, are carnivores and omnivores respectively.
* RealLife subversion: Deer. People often mistake these herbivores to be [[TheMarvelousDeer gentle beasts of the forest]], but they are actually ''extremely'' dangerous, especially during rutting season. One particularly tragic example of this is when a man was gored to death by his pet buck when it attacked him (most likely thinking he was a rival male) and ended up stabbing him in the eye and piercing his brain.
** Does, too, have killed people when they get hit by a car, come through the windshield, and start kicking out with their sharp, hard hooves in a blind panic.
*** Does will usually leave very young fawns to hide in the bushes while they go to feed, and will typically run from danger in the hope that the baby will stay hidden. If you happen across a doe and she ''doesn't'' run away, then back off quickly -- [[MamaBear her baby is probably close enough that mama thinks fighting is a better option than running]].
*** Near Kyoto, there is a place called Nara Park, which is (heavily) populated with deer, which are considered sacred there. Many tourists visit to see the deer (and temples, statues, etc.), and are warned by [[http://imgur.com/t6kL6B8 these signs]] that this trope is not necessarily true.
* Often played straight with rabbits. [[http://www.youtube.com/watch?v=_Ez5QPW-ku4 But]] [[HairRaisingHare not]] [[KillerRabbit always]].
* Usually played straight with guinea pigs.
* [[TurtlePower Turtles and tortoises]] (including herbivorous ones) are generally the most tolerant and friendly of reptiles to humans, and those who aren't tend to be very shy. Also, while iguanas can vary wildly per creature in terms in disposition, they can still form a close bond with humans akin to a dog or cat, depending on their personality. So it seems as though the most aggressive and dangerous herbivores in real life tend to be mammals. Though turtles don't usually appreciate being handled, and carnivorous ones can take fingers off if they're big enough (so keep your hands away from their faces). The herbivores play the trope very straight in most cases.
** There however, have been reports about herbivorous reptiles (namely iguanas though possibly with other species) biting and even inflicting serious wounds upon a few unlucky victims. So this should not give you the wrong idea that it's safe to approach any sort of animal at anytime, rather herbivore, mammal or non-mammal. Also, no reptiles are ''truly'' domesticated yet.
* This trope is mostly an artifact of urban and suburban living, as rural communities where people have regular contact with horses or cattle see proof it's invalid every time a temperamental animal sends someone to the emergency room.
* Bulls are notoriously aggressive. And they're a lot faster than they look.
** Even cows can be quite dangerous when provoked. Regardless of gender, a 1,000 pound animal is still a 1,000 pound animal, and it can use that bulk to its advantage.
** The wild ancestor of cattle, the Aurochs, were among the most aggressive animals known to cavemen at the time. Yet somehow, they were domesticated and were practically bred into stupidity to live with us. Living wild cattle such as African Water Buffalo and Gaur are just as deadly.
* Simply put, if any wild mammal herbivore were "friendly", it would guarantee extinction. Otherwise it would mean that it evolved in a place without any predators (very unlikely) or has a high rate of reproduction to compensate.
** Species that evolve without predators are indeed often very docile. The Dodo of Mauritius evolved on an island without predators and was noted for having no fear or aggression toward humans, who promptly ate them into extinction.
* Some species of herbivore play this straight with ''each other'', roaming in multi-species herds. Usually this is a sign that their dietary preferences are slightly different (e.g. grass vs. shrubs), and that each species in the group has a different well-developed sense (scent, hearing, sight) with which to detect herd members' mutual predators. Less competition, more chance to pick up on danger that way.
** Then mating season comes and males get very aggressive as they compete with each other for females. Only the strongest males will be able to mate with all the available females.
* Depending on the species, swans and geese can co-exist in close proximity to people and it's not uncommon to see them in urban ponds, lakes, and waterways. They are also extremely unfriendly when threatened and will attack if provoked. Especially if they [[MamaBear have cygnets]] [[PapaWolf in their care]]. An adult Mute Swan (one of the heaviest birds capable of flight) is strong enough to break a man's leg by battering it with their wings.
* Compared to the other great apes, gorillas are generally more peaceful and don't eat any meat beyond the occasional insect. Granted, adult gorillas are large enough and strong enough that they don't have any natural predators aside from the occasional very desperate leopard. Ironically, in fiction they are often portrayed as [[KillerGorilla violent beasts]].
* DinosaurMedia tends to play with this trope. Plant eating dinosaurs (like the ''Brachiosaurus'' pictured above) are usually depicted as docile creatures that are always at the mercy of the [[PredatorsAreMean scary carnivores]]. Hadrosaurs (duck-billed dinosaurs) are especially depicted as such, due to having no obvious defenses against predators. In reality, it's believed by scientists that these "peaceful herbivores" would actually have been just as capable of fighting as their predatory counterparts. Even the hadrosaurs were armed with long, whiplike tails and in some species (like ''Iguanodon'') sharp thumb spikes. Additionally, the herbivorous lineages had many dinosaurs that were more than capable of fighting carnivores, including ''Triceratops'' (with its massive horns, though it is now thought that it may have been an omnivore), ''Stegosaurus'' (the razor sharp spikes on its tail) and almost all of the sauropods (which were so incredibly huge that very few animals even tried to attack them).
** This trope is so prevalent that whenever herbivorous dinosaurs are portrayed attacking people with little to no provocation, viewers will believe they are being inaccurately portrayed as [[AscendedToCarnivorism carnivores]] or [[PrehistoricMonster Prehistoric Monsters]]. As mentioned before, many large herbivores in modern times are extremely aggressive and wouldn't hesitate in killing you if they could, so there is no doubt prehistoric ones would do the same.
