History Main / SpinosaurusVersusTRex

** ''Film/JurassicWorldFallenKingdom'': As shown in some concept arts, a ''Spinosaurus'' was supposed to make an appearance during the stampede scene, apparently to have a fight with Rexy and get killed. In the equivalent scene in the finished movie, its place is taken by a much smaller ''Carnotaurus''.

It bears mentioning there was in fact another predatory dinosaur that did coexist with ''Spinosaurus'' named ''Carcharodontosaurus'', which was actually similar in size to ''Tyrannosaurus'', and occupied a similar ecological niche. However, it doesn't have nearly the cultural pull the latter has, so this is rarely referenced. It also bears noting that while it did live in the same time and place, ''Carcharodontosaurus'' is believed to have lived in a different habitat (probably drier, more open terrain than the wetlands), and have hunted different prey than ''Spinosaurus'' (the former was an obligate carnivore that hunted other dinosaurs, while the other was primarily a piscivore), so there likely wasn't much actual competition between the two (although that doesn't stop some documentaries, like ''Series/MonstersResurrected'' and ''Series/DinosaurPlanet'', from depicting fights between the two anyway). In fact, the most popular theory for ''Spinosaurus'''s ancestors adapting to an aquatic lifestyle was precisely due to fierce competition from land-based predators for the same prey items.

* ''WesternAnimation/JurassicWorldCampCretaceous'': The final season features three fights between the ''Spinosaurus'' from ''JPIII'' and the ''Tyrannosaurus'' called "Big Eatie":
** Their first fight takes place in [[Recap/JurassicWorldCampCretaceousS5E03BattleLines the third episode]] of the season and ends in a draw.
** In the [[Recap/JurassicWorldCampCretaceousS5E11TheLastStand penultimate episode]], the two have a second fight that ends with the ''Spinosaurus'' winning and nearly killing Big Eatie.
** However, Big Eatie recovers in the [[Recap/JurassicWorldCampCretaceousS5E12TheNublarSix final episode]] and teams up with her daughter "Little Eatie" to fight the ''Spinosaurus''. Being outnumbered, the ''Spinosaurus'' chooses to run away.

* ''Film/TerrorOfMechagodzilla'' has an instance of this trope that predates ''Film/JurassicParkIII'' by 26 years. Godzilla, who is a bulky theropod modeled after ''T. rex'', battles Titanosaurus, a fictional ''Spinosaurus''-esque dinosaur with a slender build, a sail on its back and a long, crocodilian snout. -* Titanosaurus appears to be more powerful than Godzilla, though it's hard to say for sure given that it also has Mechagodzilla helping it. Godzilla is only able to defeat the other monster after the human characters [[AchillesHeel exploit its weakness to supersonic waves]]. Amusingly, Titanosaurus has a distinctive paddle-shaped tail, even though ''Spinosaurus'' wouldn't be determined to have that trait for several more decades.

* ''Film/TerrorOfMechagodzilla'' has an instance of this trope that predates ''Jurassic Park III'' by 26 years. Godzilla, who is a bulky theropod modeled after ''T. rex'', battles Titanosaurus, a fictional ''Spinosaurus''-esque dinosaur with a sail on its back and a long, crocodilian snout. The two seem to be about evenly matched, with Titanosaurus's immense physical strength making up for its lack of a BreathWeapon, though it's hard to say for certain which one is the "winner" given that Titanosaurus also has Mechagodzilla helping it, and in the end it's defeated by human characters [[AchillesHeel exploiting its weakness to supersonic waves]] rather than by Godzilla's own hand. Amusingly, Titanosaurus has a distinctively paddle-shaped tail, even though ''Spinosaurus'' wouldn't be determined to have that trait for several more decades.

* ''Manga/Zom100BucketListOfTheDead'': In Chapter 28-29, a horde of zombies attack a dinosaur museum and get entangled within some of the fossils, thus making them pseudo-zombie dinosaurs. One of them is a ''Spinosaurus'', so Akira takes control of an animatronic ''Tyrannosaurus'' modified by Lambda Chop to fight it. The Zombie Spinosaurus initially dominate the fight thanks to its larger size, but Akira receives encouragement from his friends and ultimately manages to defeat it.

* * ''VideoGame/PrehistoricKingdom'': This trope is [[DiscussedTrope Discussed]] during Nigel Marven's commentary on the ''Spinosaurus'', in which he mentions that online dinosaur forums keep asking who would win between a ''Spinosaurus'' and a ''Tyrannosaurus''. Nigel admits that he himself has never thought about it before, but now he's wondering.

** ''Anime/DoraemonNobitasDinosaur'': During the climax, the dinosaur hunters unleash their pet ''Spinosaurus'' to kill the heroes and their tamed ''Tyrannosaurus''. The ''T. rex'' goes face the ''Spino'', and the two have a fight suspiciously similar to the one from ''Film/JurassicParkIII''. First, the ''Tyrannosaurus'' headbutts its opponent, then the two dinosaurs try to bite each other. Eventually, the ''Spinosaurus'' succeeds in biting its enemy's neck and starts gripping it with its arms (probably in order to kill it in the same way that in ''JPIII''), however this time the ''Tyrannosaurus'' manages to free itself and overpower its foe, effectively sending it crashing against a wall. While it survives, the ''Spino'' is unable to get back on its feet despite its masters' insistence and lashes, and is arrested along with them by the [[TimePolice Time Patrol]] shortly after.

** Both Inverted and Played straight in the movie ''Dino Mecard: The Island Of Tinysaurs''. Tyrano the ''Tyrannosaurus'' and Spino the ''Spinosaurus'' are portrayed as good friends. However, when Tyrano is BrainwashedAndCrazy by the villains, he attacks his former dino friends and gets into a brief brawl with Spino. The two theropods run headlong into each other and try to push each other off. Spino does his best to hold his ground, but he ends up being pushed back by his opponent (though he's not defeated yet). Once again, it's one of the few instances of the ''Spinosaurus'' being portrayed as the more heroic fighter.

** While this trope is usually [[Averted AvertedTropes]] in most documentaries [[ArtisticLicensePaleontology for obvious reasons]], it is present here. Just after being described as being bigger than ''T. rex'', a ''Spinosaurus'' is shown having an encounter with a ''Tyrannosaurus'' towards the beginning. The ''T. rex'' makes a growl, but the ''Spino'' straightens up and roars menacingly. Terrified, the ''Tyrannosaurus'' [[ScrewThisImOuttaHere turns the other way and starts running for its life]].

* ''Film/AdhisayaUlagam'': When the protagonists are about to make their time machine work and return to the present day towards the end, a ''Spinosaurus'' appears and goes after them. However, a ''Tyrannosaurus rex'' suddenly comes out of nowhere and attacks it, leading to a ferocious battle between the two dinosaurs. Contrary to expectations, their fight is rather long (or at least, longer than the one from ''Film/JurassicParkIII'' and most of the other examples on this page) and involves a lot of the two dinos biting, striking with their head or tail, and pushing the other to the ground. Finally, the ''Tyrannosaurus'' bites the ''Spinosaurus'''s sail and roars fiercely, causing the ''Spino'' to walk away while the ''T. rex'' chases it.

** ''Film/JurassicParkIII'' is [[TropeMaker the very reason this trope exists.]] Shortly after their arrival on Isla Sorna, the ''Spinosaurus'' attacks the plane of Dr. Allan Grant and his group, and then starts pursuing them through the jungle. Dr. Grant and the others eventually bump into a ''Tyrannosaurus'', which decides to chase them as well. When the two gigantic theropods are brought face to face, they roar defiantly and charge at each other to have a fight. The ''T. rex'' is the first to strike, biting its opponent's neck and putting it to the ground. However, after a brief struggle the ''Spino'' manages to get up and free itself, knocking down a few trees in the process, and snaps at its adversary. Then, the two dinosaurs try to bite eack other's flanks, and the Spino strikes the ''T. rex''[='=]s leg with its claws. The ''Tyrannosaurus'' retaliates by headbutting the Spino, pushing it forward, but the ''Spinosaurus'' takes the opportunity to out-maneuver the ''T. rex'' and bite its neck. It proceeds to use its jaws and arms to [[NeckSnap twist its rival's neck]], killing it instantly. The dead body of the ''Tyrannosaurus'' tumbles to the ground, and the ''Spinosaurus'' places its hands on it before making a triumphant roar.
** ''Film/JurassicWorld'': The ''Tyrannosaurus''/''Spinosaurus'' rivalry receives a nod at the end of the film when Rexy (the ''Tyrannosaurus'' from [[Film/JurassicPark the first Jurassic Park]]) destroys a ''Spinosaurus'' skeleton shortly before [[spoiler:her fight against the ''Indominus rex'']], as a TakeThat to the last movie.

** ''Film/JurassicWorldDominion'': According to WordOfGod, the movie was initially supposed to end with Rexy and the ''T. rex'' family from ''[[Film/TheLostWorldJurassicPark The Lost World]]'' fighting against the ''Spinosaurus'' and the ''Giganotosaurus''. However, this idea was ultimately scrapped because it was deemed too overwhelming. In the finished film, the final fight only has Rexy teaming up with a ''Therizinosaurus'' to fight the ''Giganotosaurus''.

** ''VideoGame/JurassicParkArcade'': At the end of the first level, a ''Spinosaurus'' attacks the camp of the player, who has to shoot at it. When its health bar is exhausted, a ''T. rex'' arrives and roars at the Spino. The two dinos then engage in a fight during which they repeatedly bite each other's necks, while the player uses the opportunity to escape in a jeep. This time, it's left unclear who actually won the fight (both dinosaurs reappear alive later in the game, but it's unclear if they're the same individuals or not).

* ''[[VideoGame/IceAge Ice Age: Dawn of the Dinosaurs]]'': Like the movie, the game ends with the monstrous ''Baryonyx'' Rudy attacking the heroes, only for Momma Rex to show up and hit him with her head before engaging the fight against him. This time, their confrontation is actually quite longer and involves the two dinosaurs constantly trying to bite and strike each other, while the player has to help Momma in defeating Rudy. The fight still ends up in the same way though, with Momma winning by pushing Rudy off a cliff (and him being revealed to be alive shortly after).

* ''WebAnimation/DinosaursBattleWorldChampionship'' Season 1 ends with a climactic battle between the ''Tyrannosaurus'' and ''Spinosaurus'' at a volcanic landscape. After a long and brutal fight, the ''rex'' came out on top.

* ''WesternAnimation/TeenageMutantNinjaTurtles2012'': In ''WesternAnimation/HalfShellHeroesBlastToThePast'', the turtles manage to tame some dinosaurs, including a ''Tyrannosaurus'', and use them to attack a Triceratons' base. Upon seeing them coming, the Triceraton General decides to counterattack by activating their most powerful weapon, a gigantic robot ''Spinosaurus''. An inevitable confrontation between the ''T. rex'' and the ''Spino'' ensues, although this time the other dinosaurs participate in the battle as well. At first, the ''Spinosaurus'' has no problem taking on all the dinos, even grabbing the ''Tyrannosaurus'' by its tail and throwing it around like a ragdoll. However, after a while, the dinosaurs finally land some serious hits on the ''Spino'', especially when the ''T. rex'' strongly [[UsingYourHead headbutts it]] (twice!) and bites its arm. As a result, the robot-''Spinosaurus'' starts malfunctioning and the turtles take the opportunity to kill it with a [[ThisIsADrill giant drill]].

It bears mentioning there was in fact another predatory dinosaur that did coexist with ''Spinosaurus'' named ''Carcharodontosaurus'', which was actually similar in size to ''Tyrannosaurus'', and occupied a similar ecological niche. However, it doesn't have nearly the cultural pull the latter has, so this is rarely referenced. It also bears noting that while it did live in the same time and place, ''Carcharodontosaurus'' is believed to have lived in a different habitat (probably drier, more open terrain than the wetlands), and have hunted different prey than ''Spinosaurus'' (the former was an obligate carnivore that hunted other dinosaurs, while the other was primarily a piscivore), so there likely wasn't much actual competition between the two (although that doesn't stop some documentaries, like ''Series/DinosaurPlanet'', from depicting a fight between the two anyway). In fact, the most popular theory for ''Spinosaurus'''s ancestors adapting to an aquatic lifestyle was precisely due to fierce competition from land-based predators for the same prey items.

See also AnimalJingoism, BehemothBattle, CoolVersusAwesome, TheWorfEffect (either the tyrannosaur or the spinosaur may fall into this), StockShoutOuts, TakeThat, and UnpleasantAnimalCounterpart (the spinosaur usually being the unpleasant one).

* ''Anime/AttackOnTitan'': In "[[Recap/AttackOnTitanS2E1BeastTitan Beast Titan]]", there is a brief shot of a ''Tyrannosaurus'' biting the neck of a ''Spinosaurus'' during the montage of predator-prey conflicts.

* ''Animation/DinoMaster'': This shows up several times. During the course of both the show and its sequel, Touch's blue ''Tyrannosaurus rex'' and Feel's red ''Spinosaurus'' are pitted against one another on more than one occasion (it is notable that just like most of the creatures from the show, both of them have Franchise/{{Godzilla}}'s roar, for some reasons...).

%%** Played straight in the movie ''Dino Mecard: The Island Of Tinysaurs'', if this [[https://www.imdb.com/title/tt9647938/mediaviewer/rm3023662336 image]] is any indication.

** The first page of the fourth volume has a ''Spinosaurus'' recalling proudly how he wiped the floor with the ''Tyrannosaurus'' in ''Film/JurassicParkIII''.

** The cover image of the twenty-second issue features a ''Spinosaurus'' and a ''Tyrannosaurus'' seemingly having a quarrel in front of ''Gorosaurus'' while they are accompanied by other dinosaurs. [[CoversAlwaysLie This never happens in the issue, though.]]

The ''T. rex'' makes a growl, but the ''Spino'' straightens up and roars menacingly. Terrified, the ''Tyrannosaurus'' [[ScrewThisImOuttaHere turns the other way and starts running for its life]].

* ''Animation/PangeaTheNeverendingWorld'': Near the end, a baby ''Tyrannosaurus'' named Rexy ventures into a gloomy swamp where he crosses path with an enormous ''Spinosaurus''. Upon seeing him, the ''Spino'' immediately attacks and tries to devour the helpless young ''T. rex''. Thankfully, [[MamaBear Rexy's mother]] [[BigDamnHeroes arrives just in time to save her baby]] and manages to [[KnowWhenToFoldEm drive the Spinosaurus away]].

** Sobek, the ''Spinosaurus'' from ''Film/JurassicParkIII'', has fought and killed several ''T. rexes'', including the one who tried to attack [[BigBad Bridges]]'s mother in the past. His ultimate goal is to challenge Rexy, the ''Tyrannosaurus'' from [[Film/JurassicPark the first Jurassic Park]], who is considered to be the most powerful of all. [[spoiler:In Chapter 70, he finally gets his wish and manages to put up a good fight against her, but he ends up losing. However, he survives and is quite pleased with the fight, to the point that [[DefeatMeansFriendship he befriends Rexy afterwards]] and agrees to share their territory.]]

** ''Film/JurassicWorldFallenKingdom'': As shown in some concept arts, a ''Spinosaurus'' was supposed to make an appearance, apparently to have a fight with Rexy and get killed. In the equivalent scene in the finished movie, its place is taken by a much smaller ''Carnotaurus''.

** ''Jurassic Park III: Dino Defender'': Towards the end of Level 4, the ''Spinosaurus'' attacks the player, who has to flee away from it by climbing to the highest vines. The ''Spino'' still tries to reach him, however the ''Tyrannosaurus'' shows up and roars at it defiantly. The ''T. rex'' gets closer and snaps at its enemy, who makes a growl in response. The player takes this opportunity to escape, while the two dinosaurs are fighting each other. Even though most of their fight is unseen, it's implied the ''Tyrannosaurus'' won since he starts chasing the player shortly after (it could also have been a draw, considering the ''Spinosaurus'' also reappears alive and well in the last two levels).
** ''VideoGame/JurassicParkArcade'': At the end of the first level, a ''Spinosaurus'' attacks the camp of the player, who has to shoot at it. When its health bar is exhausted, a ''T. rex'' arrives and roars at the Spino. The two dinos then engage in a fight during which they repeatedly bite each other's necks, while the player uses the opportunity to escape in a jeep. This time, it's left unclear who actually won the fight (both dinosaurs reappear alive later in the game, but it's unknown if they are the same individuals or not).

** In the fourth level of 2015 ''VideoGame/JurassicParkArcade'', the player is on a mission to capture a ''Tyrannosaurus rex''. When they find one, it's in the middle of a fight against a ''Spinosaurus''. After they roar at each other, the Spino pounces on its opponent and tries to bite it, but it manages to dodge. The ''T. rex'' then grabs the ''Spinosaurus''[='=]s neck with its jaws and drags him to the edge of a cliff where he pushes it over.
** ''VideoGame/JurassicWorldTheGame'': It's possible to create ''Spinosaurus'' or ''T. rexes'' in this mobile simulator and have one of the two fight the other at any point during the game.

*** In the ''Jurassic Park III'' section, Dr. Grant and the others are chased by the ''Spinosaurus'' after their plane crash and encounter a ''T. rex'', leading the two predators to have a vicious battle. After roaring aggressively, both dinos go on the attack and repeatedly try to bite, scratch and headbutt each other. The ''Spino'' eventually bites the ''Tyrannosaurus'''s neck and puts it on the ground, but the protagonists decide to help it (seeing it as the lesser threat) by distracting the ''Spinosaurus''. Thanks to their help, the ''T. rex'' gets back on its feet and resume the fight, and both dinosaurs manage to overpower the other several times (usually by grabbing the other's neck and tossing it around), with the player constantly helping the ''rex'' in various ways when it's losing. In the end, the protagonists flee the scene by running between the two dinos while they are busy fighting. We don't see who wins the battle this time, though the fact that the ''Spino'' reappears afterwards and the ''T. rex'' doesn't heavily implies it was the former.
*** It's possible to play both the ''Tyrannosaurus'' and the ''Spinosaurus'' and have them fight one another.

** ''VideoGame/JurassicWorldEvolution'':
*** As a clear nod to the third movie, two of the Species Profiles show fights between ''Tyrannosaurus rex'' and ''Spinosaurus''.

* ''WebAnimation/JurassicParkHorror'' surprisingly [[AvertedTrope averts]] this. Despite both the ''Tyrannosaurus'' and ''Spinosaurus'' being in the same episode, the two actively pursuing the same human prey, they never fight nor even directly interact with one another.

* ''WesternAnimation/CraigOfTheCreek'': In the episode "[[Recap/CraigOfTheCreekS3E27CraigWorld Craig World]], the titular park has an attraction called "Dino-World" where the mini-figures of a ''T. rex'' and a ''Spinosaurus'' are facing off with each other. Unusually for this trope, the mini-figures are [[ShownTheirWork up-to-date with modern understanding]], with the ''T. rex'' being feathered in some parts and the ''Spinosaurus'' possessing short legs, a concave sail, and a paddle-shaped tail.

* ''WesternAnimation/DinosaurTrain'': Subverted in "The Old Spinosaurus and the Sea". The young ''Tyrannosaurus'' Buddy and his adoptive ''Pteranodon'' family go fishing in the Big Misty Sea, but they are worried of the old ''Spinosaurus'' who live there as he is known to have a bad temper and may be dangerous to them. When they end up encountering him, he yells at them for causing the fish to go away, but doesn't attack them and eventually turns out to be much nicer than he looks, and even befriends Buddy and teaches him his fishing techniques.

** Their first fight takes place in the third episode of the season and ends in a draw.
** In the penultimate episode, the two have a second fight that ends with the ''Spinosaurus'' winning and nearly killing Big Eatie.
** However, Big Eatie recovers in the final episode and teams up with her daughter "Little Eatie" to fight the ''Spinosaurus''. Being outnumbered, the ''Spinosaurus'' chooses to run away.
* ''WesternAnimation/TeenageMutantNinjaTurtles2012'': In ''WesternAnimation/HalfShellHeroesBlastToThePast'', the turtles manage to tame some dinosaurs, including a ''Tyrannosaurus'', and use them to attack a Triceratons' base. Upon seeing them coming, the Triceraton General decides to counterattack by activating their most powerful weapon, a gigantic robot ''Spinosaurus''.

As a result, the robot-''Spinosaurus'' starts malfunctioning and the turtles take the opportunity to kill it with a [[ThisIsADrill giant drill]].

Note that in RealLife, such a fight could never have happened considering the two dinosaurs lived at different periods (they were separated by over 30 million years), on different continents (''Tyrannosaurus'' lived in North America while ''Spinosaurus'' lived in North Africa), and that since TheNewTens ''Spinosaurus'' has been discovered to be [[ScienceMarchesOn an amphibious predator with a very different body type, including a finned tail]]. See [[UsefulNotes/StockDinosaursSaurischianDinosaurs here]] and [[http://youtu.be/rgqQNBuGGWg here.]] If such a fight between these two animals were ever to take place, [[HomeFieldAdvantage the outcome would greatly depend on the environment]]: the ''Tyrannosaurus'' would be heavily favored on land, while the ''Spinosaurus'' would dominate in the water. [[note]] It bears mentioning there was another predatory dinosaur that coexisted with ''Spinosaurus'' named ''Carcharodontosaurus'' that was actually similar in size and build to ''Tyrannosaurus'', and probably occupied a similar ecological niche. However, it doesn't have nearly the cultural pull the latter has, so this is rarely referenced. It also bears noting that while it did live at the same time and in roughly the same location, ''Carcharodontosaurus'' is believed to have lived in a different habitat (probably drier, more open terrain than the wetlands), and have hunted different prey than ''Spinosaurus'' (the former was an obligate carnivore that hunted other dinosaurs, while the other was a piscivore), so there likely wasn't much actual competition between the two. In fact, the most popular theory for ''Spinosaurus'''s ancestors adapting to an aquatic lifestyle was precisely due to fierce competition from land-based predators for the same prey items.[[/note]]

* ''Fanfic/PrehistoricParkReimagined'': Over the course of the titular breakout that occurs in the Phase 2 finale ''Breakout!'', Tut the ''Spinosaurus'' and Terrence the ''T. rex'' end up engaging in a vicious duel while they're both outside their respective paddocks after the latter unwittingly disturbs the former in his efforts at hunting for catfish in the moat between the park's main entrance zone and the rest of the park. Since the both of them are merely confused animals following their instincts in an unfamiliar environment (and who find each other unfamiliar due to being from separate continents, environments, and even specific periods of time within the Cretaceous Period back in the wild), neither of them is portrayed as particularly heroic ''or'' villainous. And while Terrence does manage to deal some decent wounds against Tut, and later receive some assistance close to the end from his ''Majungasaurus'' companion Mahazatra, it is nonetheless made clear that Tut would be more than capable of defeating him (and Mahazatra) in the duel by virtue of Tut himself being both bigger and more experienced in combat via his older age while Terrence and Mahazatra are both still adolescents. Fortunately, the fight ends up brought to a nonviolent end after the unexpected arrival of [[DoofyDodo Uilleam]], who subsequently bewilders the three theropods into ending the conflict by [[FearlessFool trying to challenge them to do battle with]] ''[[FearlessFool him]]''. Unlike most examples of this trope, Tut and Terrence are both portrayed fairly accurately to how their respective species are currently viewed by modern standards of paleontology, with Terrence having a sparse covering of feathers on certain areas of his body instead of being completely scaly with no feathers whatsoever and Tut having the short legs and finned tail that his species is now known to have possessed instead of the long legs and traditionally reptilian tail his species was thought to have had back in the 90s and the 2000s.

** In the episode "Running Away to the Cretaceous Period" of the 2005 anime series, Suneo gets lost in prehistoric times and befriends a ''Tyrannosaurus''. Towards the end, he is attacked by a hungry ''Spinosaurus'', but the T. rex comes to his rescue. The two reptiles first circle around each other, and then run at one another. Like in ''Film/JurassicParkIII'', the Spino manages to put down its opponent by biting its neck and tries to [[NeckSnap twist it]]. However, Suneo and Doraemon make noise to attract his attention, so it goes after them instead of finishing off the ''Tyrannosaurus''. Before it can devour them, the ''T. rex'' thankfully gets up, rushes headlong at the ''Spinosaurus'' and pushes it off a cliff with a headbutt.

* ''Animation/DinoMecard'': Downplayed in episode 52. The heroes use a ''Spinosaurus'' among many of their dinosaurs to fight the villains' three dinosaurs, an ''Ankylosaurus'', a ''Triceratops'' and a ''Tyrannosaurus''. However, there is little direct confrontation between the T. rex and the Spino, except for when the ''Tyrannosaurus'' becomes the villains' only remaining combatant and goes to smash all its enemies at once, including the ''Spinosaurus''. It's an odd example, though, in that the ''Spinosaurus'' is portrayed as the hero for once.

** The cover image of the twenty-second issue features a ''Spinosaurus'' and a ''Tyrannosaurus'' seemingly having a quarrel in front of Gorosaurus while they are accompanied by other dinosaurs. [[CoversAlwaysLie This never happens in the issue, though.]]

* ''[[https://www.youtube.com/watch?v=Ok7O46kCS_I Jurassic Park -- Life Finds A Way]]'': At the end, a ''Spinosaurus'' attacks the two protagonists, but it gets interrupted when a ''Tyrannosaurus'' suddenly appears. The two beasts roar aggressively and then run at each other to have a vicious fight. What ensues is a CurbStompBattle in the T. rex's favor, with the Spino not even landing a single hit (in its defense, it had just been hit by an flare's explosion, so it probably wasn't in the best of shape). The Tyrannosaurus bites its opponent's neck several times, headbutts it, and finally throws it against a tree, causing it to fall on the ground. Right after, the ''rex'' breaks the Spinosaurus's leg before doing the same with its neck, killing it.

* ''Fanfic/TheBridge'': Subverted with the [[https://thelostworldsurvival.freeforums.net/ Lost World RPG]] and extended short stories detailing the ''Jurassic Park'' side of the Amalgam'verse. While the parent ''T.rex'' from ''The Lost World'' and the ''Spinosaurus'' from ''Jurassic Park III'' both appear, they don't fight or encounter one another. The ''Spinosaurus'', nicknamed "Snoke" by the players, does however fight the hybrid "Ultimasaurus" which is based off a ''Tyrannosaurus'' and is presented in a rare anti-heroic role when the players help it kill the hybrid monster. The prequel short story "Emperor of Sorna" plays the ideas for the third film straight, where Dr. Wu intentionally engineered the ''Spinosaurus'' as a hybrid itself to control the ''Tyrannosaurus'' population so they didn't overrun the ecosystem by being their natural counter; this is why it's much stronger or resilient than a normal ''Spinosaurus''. While neither species is presented as any better or worse than normal animals, the "Snoke" is considered a crucial part to maintaining the Isla Sorna ecosystem.

** Carnifex, the son of the two aforementioned ''Spinosaurus'', frequently kills juvenile ''T. rexes'' that his master Bridges feeds him with. Unlike his father Sobek, he has no respect towards them and views them as easy kills. [[spoiler: However, he eventually faces off Limper (the baby ''Tyrannosaurus'' from ''Film/TheLostWorldJurassicPark'' all grown up) and [[CurbStompBattle gets thrashed so brutally]] that he flees in terror into the jungle. Thereafter, he starts reconsidering his opinion about ''T. rexes'']].

** Discussed. During the second episode, the Team discovers a ''Spinosaurus'' in South Africa and Allan Grant has a conversation with Zia in which he recalls how much the one he encountered was aggressive towards ''Tyrannosaurus''. Apparently, this was because it was actually a hybrid between a ''Spinosaurus aegypticus'' and a ''Tyrannosaurus rex'' (nicknamed ''Spinosaurus rex'' by Grant), and the T. rexes are known to be extremely territorial.

* ''Fanfic/PrehistoricParkReimagined'': Over the course of the titular breakout that occurs in the Phase 2 finale ''Breakout!'', Tut the spinosaurus and Terrence the t. rex end up engaging in a vicious duel while they're both outside their respective paddocks after the latter unwittingly disturbs the former in his efforts at hunting for catfish in the moat between the park's main entrance zone and the rest of the park.

Unlike most examples of this trope, Tut and Terrence are both portrayed fairly accurately to how their respective species are currently viewed by modern standards of paleontology, with Terrence having a sparse covering of feathers on certain areas of his body instead of being completely scaly with no feathers whatsoever and Tut having the short legs and finned tail that his species is now known to have possessed instead of the long legs and traditionally reptilian tail his species was thought to have had back in the 90s and the 2000s.

** ''Film/JurassicParkIII'' is [[TropeMaker the very reason this trope exists.]] Shortly after their arrival on Isla Sorna, the ''Spinosaurus'' attacks the plane of Dr. Allan Grant and his group, and then starts pursuing them through the jungle. Dr. Grant and the others eventually bump into a ''Tyrannosaurus'', which decides to chase them as well. When the two gigantic theropods are brought face to face, they roar defiantly and charge at each other to have a fight. The ''T. rex'' is the first to strike, biting its opponent's neck and putting it to the ground. However, after a brief struggle the ''Spino'' manages to get up and free itself, knocking down a few trees in the process, and snaps at its adversary. Then, the two dinosaurs try to bite eack other's flanks, and the Spino strikes the T. rex's leg with its claws. The Tyrannosaurus retaliates by headbutting the Spino, pushing it forward, but the Spinosaurus takes the opportunity to out-maneuver the ''T. rex'' and bite its neck. It proceeds to use its jaws and arms to [[NeckSnap twist its rival's neck]], killing it instantly. The dead body of the ''Tyrannosaurus'' tumbles to the ground, and the ''Spinosaurus'' places its hands on it before making a triumphant roar.

* ''Lost'', a ''Literature/{{Dinotopia}}'' novel by Creator/AlanDeanFoster has an example five years before ''Film/JurassicParkIII'' popularized the trope that is pretty funny in retrospect. A pair of Tyrannosaurus rex confronts a pair of Spinosaurus who are portrayed as smaller predators who cower before them.

* The spanish dinosaur novel, ''Desextinción'' has an alpha male ''T-Rex'' fighting against a father male ''Spinosaurus'' which he kills and eats.
* Probably the [[UrExample earliest example]] comes from one instalment published in 1988 of a storybook series created by Rourke Publishing, where [[https://cdn.discordapp.com/attachments/512505220241031172/1108835480025436160/IMG_6027.png in one spread]], a ''Spinosaurus'' about to scavenge a sauropod carcass is confronted by a T. rex.

** ''Series/ZyudenSentaiKyoryuger'': The ''Film/ZyudenSentaiKyoryugerGaburinchoOfMusic'' movie contains an action scene in which Tobaspino (who's a ''Spinosaurus'' converted into a HumongousMecha) fights against the Zyudenryu in the middle of the city, including Gabutyra (who's based on a ''Tyrannosaurus''). The confrontation between the two is strikingly similar to the ''Film/JurassicParkIII'' fight, as Gabutyra first attacks his foe by biting his head, only for him to quickly break free and push him away. Then, both fighters try to bite the other, and Tobaspino manages to bite his rival onto his neck. The Spino subsequently throws the T. rex against a building, thus winning the fight for once.
** ''Series/KishiryuSentaiRyusoulger'': {{Downplayed}}. The LandSeaSky trio of [[TransformingMecha primary kishiryu]] are Tyramigo (T. Rex), [=MosaRex=] (Mosasaurus) and Pterardon (Pteranodon). Tyramigo is used by the main team, while [=MosaRex=] is used by the SixthRanger... and [[CombiningMecha can combine with]] the limbs and sail of a Dimetrodon-based mecha to become the more powerful [=SpinoThunder=] ([[ExactlyWhatItSaysOnTheTin a spinosaurus with electric powers]]).

** ''VideoGame/JurassicParkDinosaurBattles'' features both the ''Spinosaurus'' and the ''Tyrannosaurus'' among the dinosaurs who can fight each other. The game's cover even shows a Spino attacking a T. rex.

** In the fourth level of 2015 ''VideoGame/JurassicParkArcade'', the player is on a mission to capture a ''Tyrannosaurus rex''. When they find one, it's in the middle of a fight against a ''Spinosaurus''. After they roar at each other, the Spino pounces on its opponent and tries to bite it, but it manages to dodge. The ''T. rex'' then grabs the Spinosaurus's neck with its jaws and drags him to the edge of a cliff where he pushes it over.
** ''VideoGame/JurassicWorldTheGame'': It's possible to create ''Spinosaurus'' or ''T. rexes'' in this mobile simulator and have one of the two fighting the other at any point during the game.

* In the first ''VideoGame/ZooTycoon'' game, the one where both are adoptable animals, if you were to put the two together, they would fight. Per the coding, the T-Rex always wins.

* [[https://www.youtube.com/watch?v=2ylvPtk-DNA This musical parody]] of ''Film/JurassicParkIII'' by LHUGUENY features the fight between the ''Spinosaurus'' and ''Tyrannosaurus''. As in the movie, the ''T. rex'' scores the first hit by biting the ''Spinosaurus'''s neck ([[SkewedPriorities which doesn't stop him from singing]]), but then the ''Spinosaurus'' manages to free himself and grabs the ''Tyrannosaurus'' by using his hands and jaws in order to kill him with a NeckSnap just like in the movie. The Spinosaurus even notes [[LeaningOnTheFourthWall that the audience]] was upset by the T. rex's death.
* ''WebAnimation/DinosaursBattleWorldChampionship'' Season 1 ends with a climactic battle between the Tyrannosaurus and Spinosaurus at a volcanic landscape. After a long and brutal fight, the Rex came out on top.
* ''WebAnimation/JurassicParkHorror'' surprisingly [[AvertedTrope averts]] this. Despite both the ''Tyrannosaurus'' and ''Spinosaurus'' being in the same episode, the two actively pursuing the same human prey, they never fight each other nor have they directly interact with one another.

* Goji Center also discusses a possible confrontation between the Spino and T-Rex in this [[https://www.youtube.com/watch?v=EIyzXfaAfB4 video]], going into detail about their respective attributes and combat capabilities. Like BBC above, it was concluded that either could win a fight, depending on the terrain.

* ''WesternAnimation/DinoRanch'': In "This Ranch Ain't Big Enough", Biscuit (a T.Rex) protects the kids from a Spinosaurus. When the Spinosaurus returns in need of medical help, the kids try to keep Biscuit from finding out so a new fight won't start. [[spoiler:Biscuit finds the Spinosaurus but, understanding the situation, lets the Spinosaurus go without a new fight]].

** However, Big Eatie recovers in the final episode and teams up with her daughter "Little Eatie" to fight the ''Spinosaurus''. Being outnumbered, the Spinosaurus chooses to run away.

* ''WesternAnimation/TeenTitans2003'': In "[[Recap/TeenTitansS4E13TheEndPartThree The End (Part 3)]]", Beast Boy is confronted to a [[EvilTwin demonic clone]] of himself with the same power of shapeshifting into animals. After fighting by turning into various creatures, Beast Boy finally takes the form of a ''Tyrannosaurus rex'', which had been portrayed throughout the series as his most powerful form. The clone one-ups this by becoming a ''Spinosaurus''. While most of the ensuing fight takes place offscreen, from what we're shown it seems to be very similar to the one from ''Film/JurassicParkIII'', with the ''T. rex'' taking the first shot by biting the ''Spino'''s neck and putting him to the ground, only for him to eventually free himself and overpower his adversary. At the end of the fight, Beast Boy's T. rex form gets thrown into some rocks and has to turn into a spider to escape from the Spino's sight. It is notably one of the few times besides the movie where the ''Spinosaurus'' actually wins the fight.

Note that in RealLife, such a fight could never have happened considering the two dinosaurs lived at different periods (they were separated by over 30 million years), on different continents (''Tyrannosaurus'' lived in North America while ''Spinosaurus'' lived in North Africa), and that since TheNewTens ''Spinosaurus'' has been discovered to be [[ScienceMarchesOn an amphibious predator with a very different body type, including a finned tail]]. See [[UsefulNotes/StockDinosaursSaurischianDinosaurs here]] and [[http://youtu.be/rgqQNBuGGWg here.]] If such a fight between these two animals were ever to take place, [[HomeFieldAdvantage the outcome would greatly depend on the environment]]: the ''Tyrannosaurus'' would be heavily favored on land, while the ''Spinosaurus'' would dominate in the water. [[note]] It bears mentioning there was another predatory dinosaur that coexisted with ''Spinosaurus'' named ''Carcharodontosaurus'' that was actually similar in size and build to ''Tyrannosaurus'', and probably occupied a similar ecological niche. However, it doesn't have nearly the cultural pull the latter has, so this is rarely referenced. It also bears noting that while it did live at the same time and in roughly the same location, ''Carcharodontosaurus'' is believed to have lived in a different habitat (probably drier, more open terrain than the wetlands), and have hunted different prey than ''Spinosaurus'' (the former was an obligate carnivore that hunted other dinosaurs, while the other was a piscivore), so there likely wasn't much actual competition between the two.

** Believe it or not, there is an example of this trope in the ''Franchise/JurassicPark'' franchise that actually predates the release of ''[[Film/JurassicParkIII JP III]]''. In the 1999 fighting style video game ''VideoGame/WarpathJurassicPark'', the ''Spinosaurus'' and the ''Tyrannosaurus rex'' are among the playable dinosaurs, and the two can fight one another at any time.

** Also happens in the ''Film/JurassicParkIII'' [[VideoGame/JurassicParkArcade Arcade game]]. At the end of the first level, a ''Spinosaurus'' attacks the camp of the player, who has to shoot at it. When its health bar is exhausted, a ''T. rex'' arrives and roars at the Spino. The two dinos then engage in a fight during which they repeatedly bite each other's necks, while the player uses the opportunity to escape in a jeep. This time, it's left unclear who actually won the fight (both dinosaurs reappear alive later in the game, but it's unknown if they are the same individuals or not).
** Strangely, averted in ''Jurassic Park III: Island Attack''. Despite being based on the ''Film/JurassicParkIII'' movie and featuring the ''T. rex'' and the ''Spinosaurus'' (who both look a lot like their movie counterparts) as major enemies in several scenes, the two never fight or even encounter each other during the game.
** Naturally, the 2002 video game ''VideoGame/JurassicParkDinosaurBattles'' features both the ''Spinosaurus'' and the ''Tyrannosaurus'' among the dinosaurs who can fight each other. The game's cover even shows a Spino attacking a T. rex.
** Likewise, one of the covers of ''VideoGame/JurassicParkOperationGenesis'' features a fight between the ''Spinosaurus'' and the ''Tyrannosaurus'' in the middle of the jungle.
*** Both dinosaurs also appear in the game, and they tend to battle each other for territorial reasons whenever they meet, though any of them can end up as the victor. It's possible for them to coexist peacefully for a short period of time, but sooner or later the two will eventually fight to the death.
** ''Tyrannosaurus'' and ''Spinosaurus'' are some of the available dinosaurs in ''VideoGame/JurassicParkBuilder'', therefore any of them can fight the other during the game.

** Unsurprisingly, this happens in the ''Jurassic Park III'' section of ''VideoGame/LEGOJurassicWorld''. Like in the film, Dr. Grant and the others are chased by the ''Spinosaurus'' after their plane crash and encounter a ''T. rex'', leading the two predators to have a vicious battle. After roaring aggressively, both dinos go on the attack and repeatedly try to bite, scratch and headbutt each other. The ''Spino'' eventually bites the ''Tyrannosaurus'''s neck and puts it on the ground, but the protagonists decide to help it (seeing it as the lesser threat) by distracting the ''Spinosaurus''. Thanks to their help, the ''T. rex'' gets back on its feet and resume the fight, and both dinosaurs manage to overpower the other several times (usually by grabbing the other's neck and tossing it around), with the player constantly helping the ''rex'' in various ways when it's losing. In the end, the protagonists flee the scene by running between the two dinos while they are busy fighting. We don't see who wins the battle this time, though the fact that the ''Spino'' reappears afterwards and the ''T. rex'' doesn't heavily implies it was the former.
*** In addition, it's possible to play both the ''Tyrannosaurus'' and the ''Spinosaurus'' and have them fight one another.

** ''VideoGame/JurassicWorldEvolution'': As a clear nod to the third movie, two of the Species Profiles show fights between ''Tyrannosaurus rex'' and ''Spinosaurus''.
