->''"Dino Thunder, Power Up!"''
->''"White Ranger, Dino Power!"''
-->--'''[[ByThePowerOfGreyskull Morphing calls]]''', ''Power Rangers Dino Thunder''

It's the first day of school in Reefside, and three students have already run afoul of the SadistTeacher and are given detention. Thankfully, the new biology teacher doesn't want to be stuck with watching them, so he tells them that if they go out and bring back something prehistoric for his paleontology studies, he'll call it off. During their search, they stumble into a secret lab and decide to swipe some ancient-looking gemstones to fill the requirement.

The good news here is that the gems were infused with energies [[PhlebotinumKilledTheDinosaurs from the impact that wiped out the dinosaurs]], and have already "bonded" with the students, giving them superpowers. The bad news is that a saurian MadScientist wants their power to start a new age of dinosaurs and is coming after the kids. The ''really'' bad news is that the gems are {{Clingy Macguffin}}s, and taking their power requires killing the current hosts.

The really, ''really'' '''good''' news is that the new bio teacher is none other than [[MemeticBadass Dr. Thomas "Tommy" Oliver]], and [[Series/MightyMorphinPowerRangers he's had a]] [[Series/PowerRangersZeo little experience]] [[Series/PowerRangersTurbo with this kind of thing.]]

Doug Sloan, Ann Austen, Jackie Marchand, and Jason David Frank all return in season 12 of ''Franchise/PowerRangers,'' based on ''Series/BakuryuuSentaiAbaranger''. The dinosaur theme apparently made everyone nostalgic and as the season also boasted the 500th episode (a clipshow episode where the show recapped each incarnation of the franchise in a condense manner) and a rarity in the form of an episode of ''Abaranger'', which was given a gag dub as far as being a show within a show.

The series is generally considered to be one of the stronger seasons of the Disney Era, with fun, strong characters and a wonderful team dynamic between them. It was far from free of problems, though: due to contract issues, Jason David Frank only really appeared in half of the season, with the character spending most of the season frozen in amber or invisible/only visible in morphed form.

But, Come on, everyone knows Tommy is the most [[TotallyRadical morphinomenal]] Ranger EVER.

(Offended Jason fans are invited to take this opportunity to rewatch ''[[Series/PowerRangersWildForce Forever Red]]'', and revel in his clearly-displayed badassitude).

Also of note is that this is the [[Series/PowerRangersNinjaStorm second]] ''Power Rangers'' season to only have one female Ranger. [[ActionGirl She more than made up for it, though]], and appeared in the MilestoneCelebration episode "Once A Ranger" as representative of this season.

Succeeded by ''Series/PowerRangersSPD''

Has a [[Characters/PowerRangersDinoThunder character sheet]].

Dino Thunder was the last season of the Disney Era to have full team ups with the [[Series/PowerRangersNinjaStorm preceding]] and [[Series/PowerRangersSPD succeeding]] seasons.

----
!!Recurring ''Power Rangers'' tropes include:

* ActionGirl: Kira
* AllYourBaseAreBelongToUs: [[spoiler: Zeltrax trashes the Dino Lab]]
** Also in the inversion of this trope in the entire PR series: [[spoiler: The Rangers storm Mesogog's base and are able to destroy it]].
* AnimalThemedSuperbeing
* BigBad: Mesogog
* ChestInsignia: The team dinosaur-footprint logo on the chest; the White Ranger has a version on his belt instead and the Triassic Ranger version is modified to look like a Styracosaur head.
* CityOfAdventure: Reefside
* TheDragon: CoDragons Elsa and Zeltrax
* FinishingMove
* FiveManBand: PowerTrio [[ThreePlusTwo Plus Two]] version:
** TheLeader: Conner
** [[TheSmartGuy Smart]] [[TheLancer Lancer]]: Ethan
** TheChick: Kira
** TheBigGuy: Tommy (Dr. Thomas Oliver)
** SixthRanger[[note]]Yes, he's only the fifth team member. The actual number doesn't matter to the trope.[[/note]]: Trent
* FiveTokenBand: Two Caucasians, an African-American, a Native American, and an Asian (Filipino).
* FleetingDemographicRule: It's been 11 years since [[Series/MightyMorphinPowerRangers the last dinosaur-themed Rangers]].
** It's [[PlayingWithATrope played with,]] however, mostly because of Tommy's return.
* HomeBase: the Dino Lab under Tommy's house
** ElaborateUndergroundBase
* HumongousMecha
** AnimalMecha: of the prehistoric variety
** CombiningMecha: the Dinozords
** MechaExpansionPack: The Parasaurzord, Cephalozord, Dimetrozord, and Ankylozord (the Stegozord is also an expansion for the Thundersaurus Megazord, but mostly used as a main component for the Dino Stegozord).
** TransformingMecha: the Mezodon Rover
* LawOfChromaticSuperiority: The Red Ranger usually gets most of the cool toys, but Conner gets a power-up by ''taking power from the rest of the team'' (at least at first) to become the Triassic Ranger, and then ''the Triassic Ranger has its own Battlizer''. Plus not only does his Tyrannozord form the bulk of the main Megazord, but his Triassic-mode "Mezodon" (''Styracosaurus'') zord forms a Megazord in itself.
** Funnily enough, the one time an upgrade goes to someone else (Ethan's Hovercraft Cycle), you have Conner commenting that he wants one of those.
* LimitedWardrobe: After Tommy gets the Black Ranger powers, he notes that he's going to have to go shopping for black clothing. It's the first acknowledgement of the Ranger tradition of color-coordinated civilian outfits and a massive LampshadeHanging.
** Interesting note: before this, we see him wearing nothing but BLACK.
* TheMentor: Tommy
* {{Mooks}}: Tyrannodrones[[note]]To date the last Power Rangers exclusive mook[[/note]]; also Triptoids a few times.
* {{Motifs}}: EverythingsBetterWithDinosaurs
** DinosaursAreDragons: Trent's mecha is called the "Dragozord", despite clearly being a pterosaur (specifically, a tupuxuara).
** StockDinosaurs: At least most actually ''were'' dinosaurs, unlike [[Series/MightyMorphinPowerRangers the last time...]] (note we said "most"; if you want to get technical the pterosaurs and dimetrodon aren't true dinosaurs. It's still better than a mastodon, pterodactyl, sabertooth tiger, and whatever the Dragonzord was supposed to be). The "stock" part is averted with the "Dragozord", which is a lesser-known pterosaur with a large head crest called a ''Tupuxuara''.
*** PteroSoarer: Kira and Trent
*** RaptorAttack: The Raptor Riders, and the Raptor Cycles take on a bit of the motif too.
*** TyrannosaurusRex: Connor
** {{Whateversaurus}}: The Thundersaurus Megazord. Kira also ad-libs "morphasaurus" when she's at a dino dig and needs an excuse to pull Tommy away.
* RagtagBunchOfMisfits: A jock, a nerd, a rocker, an artist, and their MemeticBadass teacher.
* {{Recycled IN SPACE}}!: Power Rangers [[foldercontrol]]

[[folder: with [[Everythings Better With Dinosaurs DINOSAURS ]]
... [[Series/MightyMorphinPowerRangers AGAIN]]!]]
* StockFootage: There are the usual issues in recycling footage from an entirely different show, but this season clashed with some intended story beats and forced the creators to find workarounds: the White Ranger Clone was created to keep in step with the fact that [=AbareKiller=] remained an enemy throughout ''Abaranger'', and plans to make the Triassic Ranger a proper SixthRanger had to be scrapped because it clashed with [=AbareMax=]-as-powerup footage too much.
** Plus little things left over from ''Abaranger'' being Japanese. In "Beneath the Surface", Conner tries to justify some especially Japanese-flavored footage with "It's attacking Little Tokyo!" "A Ranger Exclusive" has a TV station control room staffed by all Asian guys. And one use of the Triassic Dimension leaves a character plummeting to Earth - over Japan.
* StockSuperpowers
** InstantArmor: Ethan
** {{Invisibility}}: Tommy and Trent (though Trent's is called "camouflage")
** MakeMeWannaShout: Kira
** SuperSpeed: Conner; he usually uses it for a FlashStep
* SuperMode: Super Dino Mode. Almost parodied with Conner, as he ''also'' has the Triassic Ranger mode, and then a Battlizer on top of Triassic Ranger.
* {{Thememobile}}:
** HorseOfADifferentColor: The Raptor Riders
** CoolBike: The Raptor Cycles and Ethan's Hovercraft Cycle
** Tommy's and Trent's Dino [=ATVs=]
** BigBadassRig: The Triceramax Command Center Truck
* TransformationIsAFreeAction: Subverted in "Game On" when Conner is blasted (incidentally sending him on an inconsistent trajectory).
* TrueCompanions: Conner, Kira, Ethan, and Trent become this.
* WeaponOfChoice
** SwissArmyWeapon: [=ThunderMax=] Sabers/Blasters
** SimpleStaff: Conner's Tyranno Staff
** ShieldBash: Ethan's Tricera Shield
** KnifeNut: Kira's Ptera Grips
** HeroesPreferSwords: Tommy's Brachio "Staff"
** ImprobableWeaponUser: Trent's Drago Sword (an oversized, bladed feather quill)
** LuckilyMyShieldWillProtectMe[=/=]SwissArmyWeapon: Conner's (as Triassic Ranger) Shield/Sword of Triumph
** KillerYoYo: Conner's (as ''Battlized'' Triassic Ranger) Dragon Yo-Yo
* WordPower
** ByThePowerOfGreyskull: "Dino Thunder, Power Up!" and "White Ranger, Dino Power!"
*** The latter being a CallBack to Tommy's White Tiger theme from Morphin'.
** {{Invocation}}: "Tyranno power!" "Tricera power!" "Ptera power!" "Brachio power!" "Drago power!"

!!This subseries contains examples of:

* AcademyOfAdventure: Reefside High
* AdaptedOut: The Raptor Riders weren't cut out of the show entirely like some ''Sentai'' elements have been, but they were upstaged only a few episodes after their introduction by the Raptor Cycles and only made a few minor appearances. The same goes for the Triptoids, who made a couple token appearances but were otherwise replaced by the Tyrannodrones.
* AdventuresInComaland: "Fighting Spirit"
* AliensInCardiff: The location of the Abyss of Evil was revealed to be somewhere in western Fresno County in California (which is the perfect place to put a secret ninja academy).
* AllNaturalGemPolish: Averted, at least somewhat. All the Dino Gems are brightly colored and not dirty at all, but only the White Gem that Mesogog specially prepared is cut. Tommy obviously never bothered with the ones he found.
* AlphaBitch: Cassidy. Becomes a LovableAlphaBitch halfway through.
* AndStarring: Jason David Frank
* BadSanta: Conner's nightmare in "In Your Dreams"
* BadassLongcoat: Mesogog
* BadassTeacher: Tommy, who at the end of the season [[RetiredBadass decides to live the quiet life teaching.]] Again.
* BattleInTheCenterOfTheMind: Tommy in "Fighting Spirit".
* BeamOWar: Tori vs. Kira, except it's [[MakingASplash water]] against [[MakeMeWannaShout sound]].
* BigGood: Tommy takes on this role as the mentor to the new team, and they note that without him, they would likely not survive their battle with Mesogog.
* BlackAndNerdy: Ethan
* {{Bowdlerise}}: Jason Frank wasn't allowed to use his trademark {{Kiai}} ("Aiyah! Si-aiyah!") because Disney was convinced he was ''swearing''.
* BoxingKangaroo: The Cephalozord is used as a dinosaur version. It even gives the Megazord, more or less, a superpowered punch.
* BrainwashedAndCrazy: Lothor somehow has the means to do this to the Wind Rangers after he escapes from the Abyss.
** This happens to Kira in "The Missing Bone", courtesy of a [[MonsterOfTheWeek MOTW]] with mind control powers.
** The finale reveals that Elsa was a case of this all along.
* BreakingTheFourthWall: At the end of one episode, Tommy thanks the Rangers for hanging in with him. Because of camera set up, he's looking directly down the camera while talking to them. His lines from memory:
-->Tommy: I just want to thank you from the bottom of my heart for hanging in there with me. I know it's been a while. It means a lot to me.
* TheCastShowoff: Kira's band, the actress Emma Lahana is a singer with several albums.
* ChainedByFashion: referenced in "Back In Black":
-->'''Zeltrax:''' You're not getting through that portal unless you're in chains!
-->'''Kira:''' ''I'' might be able to pull that look off, but these guys? No way!
* ClarkKenting: Elsa/Principal Randall. {{Lampshaded}}:
-->'''Conner:''' I can't believe we didn't work it out! They look exactly the same, except one wears glasses.
-->'''Ethan:''' Hey, Clark Kent and Superman look the same, but no one ever puts that together.
* ClingyCostume: This happened to Tommy when [[WrittenInInfirmity Jason David Frank was unavailable except for voiceovers for a while]].
* ClipShow: Two: "Legacy of Power", the 500th episode that recapped every previous season; and "A Test of Trust", which recapped Trent's actions throughout the season.
* CoolTeacher: They don't come any cooler than Tommy Oliver the previously Green, White, and twice Red Ranger who takes on the Black Dino Thunder Ranger this season. This is the man who, it has been noted, could now make an entire team of rangers just from past powers.
* ContinuityNod: Tommy and Kira find a photograph of the original team. Kira laughs at his long hair.
** ''[[Series/PowerRangersNinjaStorm Ninja Storm]]'' also gets a shoutout in the premiere:
--->'''Mesogog:''' The citizens of Reefside will think that idiot Lothor has returned.
** And then the {{Crossover}} episode drove that home.
** Tommy's Dino Morpher works differently than the others. His is activated by inserting a key and turning it. You know, [[Series/PowerRangersTurbo like the last one he used.]]
** A subtle one to ''Series/MightyMorphinPowerRangers''. [[spoiler:Zordon mentioned that two identical Pink Rangers at the same place and same time would be dangerous. When there are two White Rangers with exact same powers existing at the same time, it begins to make one breakdown completely, forcing a battle to the death between the two.]]
* ContractualGenreBlindness: Tommy, for not suggesting that the Rangers check for somebody who has started wearing white once the White Ranger shows up. Especially bad considering his LampshadeHanging earlier in the series.
** Like Tommy though, Trent already wore a lot of his Ranger color ''before'' he ever became a Ranger.
* CorruptCorporateExecutive: Mercer is teased as one.
* CuteBruiser: Kira
* DarkSecret: Trent, the White Drago Ranger, is the adoptive son of [[spoiler: Anton Mercer, a.k.a. [[BigBad Mesogog]]]].
* DatingServiceDisaster: "A Star Is Torn" sees Ethan sign up for a dating service site. To no troper's surprise, he's set up with Cassidy. What is surprising is that they go with it for the next few episodes, leading directly to her CharacterDevelopment.
* DeathGlare: Tommy gives Trent one when the rest of the team finds out the above.
* DefrostingIceQueen: Cassidy
* DepravedKidsShowHost: The Funky Fisherman in "It's a Mad, Mad, Mackerel" is a G-rated version, as he's more cranky than anything else.
* DeusExMachina: Multiple, sometimes more than one for the same problem because the first one didn't solve it and almost always with a more [[FridgeLogic logical]] alternative already introduced in the story.
* EEqualsMCHammer: Some of Dr. O's lessons.
* EvasiveFightThreadEpisode: The first time the Dino team fights the brainwashed Wind Rangers, it's an aversion -- the Dinos lose badly. The second time (unmorphed) is a little more even, and the other Ninja Storm Rangers interrupt before they can morph.
* EverythingsBetterWithDinosaurs: As above, but also used literally as a plot point: Mesogog believes this to the point where his master plan is to ''turn the entire human population into dinosaurs.''
* EverythingsBetterWithSpinning: The White Ranger's morphing sequence features him jumping into the air & spinning around as his costume forms around him.
* EvilCounterpart: Replicant Zord was the dark version of Thundersaurus Megazord after Ugly Monster transfer into the robot.
* EvilKnockoff: The White Drago Ranger clone.
* EvilSoundsDeep: Brainwashed Trent/White Ranger Clone.
* EvilTeacher: Elsa as Principal Randall.
* {{Expy}}: Trent is a Ranger with a chest shield and a [[DinosaursAreDragons dragon]] Zord who starts out evil due to being BrainwashedAndCrazy but then joins the team he once fought against, much like [[Series/MightyMorphinPowerRangers Tommy did]].
* FantasyHelmetEnforcement: While the helmets on their suits don't count, safety helmets are used a lot to the point of FridgeLogic. There's one instance of a helmet appearing out of nowhere between shots, when Tommy has to drive a barely-conscious Elsa out of the area on an ATV. Earlier, Tommy also makes a point of fastening his seat belt before driving off even though the ''freaking Tyrannosaur'' chasing him seemed to be the greater safety hazard.
** Lampshaded by the man himself: "Yeah, lock the door, Tommy. Real good."
*** In a jeep with the ''top down'' no less!
**** [[Series/GekisouSentaiCarranger Red Racer]] [[Series/PowerRangersTurbo would be proud.]]
* FoeYay: Elsa and Tommy. [[{{in-universe}} The rest of the cast even picks up on it]] in "Beneath the Surface".
* FollowInMyFootsteps: A point of contention between Dr. Mercer and Trent, as Mercer wants to groom Trent for the business world and thinks his drawing hobby and afterschool job at Hayley's are beneath him. In Mercer's defense, some of his lines suggest that [[spoiler:he's preparing Trent to handle being on his own in case he loses his internal battle with Mesogog.]]
* GagDub: "Lost and Found in Translation", obviously.
* GadgeteerGenius: Hayley.
* GenreSavvy: One MonsterOfTheWeek shoots at Conner while he's morphing, disrupting the morph and sending him flying through a window.
* GettingCrapPastTheRadar: In "Fighting Spirit", Tommy's [[CrowningMomentOfAwesome comeback episode]], the Thundermax Megazord's drill, if you watch carefully, impales the Monster of the Day through a mountain.
* GilliganCut: Blake gets one in the second part of the ''[[Series/PowerRangersNinjaStorm Ninja Storm]]'' crossover when [[spoiler:they return to the Abyss of Evil to get their Ranger powers back.]]
* GoodScarsEvilScars: Elsa has a scar running from her lower lip to the bottom of her chin, painted black with just-visible stitches. Ironically, it acts like a 'good' scar, staying hidden and not detracting from her looks, but denotes her as a villain. The marking disappears in her mid-season redesign.
** Zeltrax is also [[StarWars so injured from a chemical fire that he cannot survive without his metal 'armor' and cybernetic parts, which makes him, for half of the season, see Mesogog as a father-figure for giving him.]]
* HappilyAdopted: Dr. Mercer took Trent in after his biological parents died at an archaeological dig. Their relationship may be strained most of the season, but Trent still has no problem calling him "Dad".
* IdolSinger: Kira
* ImprobableAge: In the beginning of the franchise, Tommy was a moderately good student grades-wise that was forgetful to the point that fans [[MemeticMutation claim]] he has Swiss cheese for a brain. Come ''Dino Thunder'', he's managed to get a [=PhD=] in six years or less, among other things (such as the whole "mad scientist, then got teaching license" thing, plus whatever he was doing during "Forever Red").
** Lampshaded in the [[Series/PowerRangersOperationOverdrive Operation Overdrive]] episode "Once a Ranger":
--->'''Adam:''' I still can't believe he's a Doctor...
* InternalHomage: The first episode, "Day of the Dino", is a reference to the first episode of MMPR, "Day of the Dumpster."
** Trent's morphing call is "White Ranger, Dino Power." During [[Series/MightyMorphinPowerRangers Tommy's tenure as a White Ranger]], his {{leitmotif}} was called "White Ranger, Tiger Power."
* IntrepidReporter: Or so Cassidy wishes, but her general lack of common sense puts her dangerously close to being a RedShirtReporter. She also has shades of the SchoolNewspaperNewshound when she actually pursues school topics.
* InvisibleMainCharacter: Tommy, for a while
* IslandBase: Mesogog's lab fortress
* ItsProbablyNothing: Ethan shoots this down in the first episode. "That ain't the wind. As much as we'd like it to be... it ain't."
* JerkJock: Conner, at first. By a few episodes in, he's already completed the transformation to JerkWithAHeartOfGold.
* {{Leitmotif}}: The Brachiozord. Just... the Brachiozord.
* LastVillainStand: After his base is destroyed and his plan to transform everyone on the planet into reptilian creatures is foiled, Mesogog appears before the rangers for a final battle and uses the energy he absorbed from the Dino Gems to take on a OneWingedAngel form. It takes all the rangers' power to destroy him once and for all.
* LetsYouAndHimFight: With the ''Ninja Storm'' Rangers. For years this was the series's ''only'' teamup episode to do this, until the Red RPM and Samurai Rangers had a brawl.
* LiteralSplitPersonality: After having enough of fighting [[spoiler: Anton for the body they shared, Mesogog decided to separate himself from Mercer so he could be around 24/7. [[NiceJobFixingItVillain No longer attached to an innocent man, the Rangers were free to take him down]]]].
* LiquidAssets: One [[MonsterOfTheWeek MOTW]] sucks youth from victims in "Diva In Distress", including Devin, Cassidy, and Kira's pop star friend.
* LukeIAmYourFather: [[spoiler: Mesogog is the SuperpoweredEvilSide of Trent's foster dad.]]
* MaximumFunChamber: Mesogog's unseen punishment chamber.
* MediumBlending: The episode "Drawn into Danger", where the Dino Thunder Rangers were [[{{Rotoscoping}} Rotoscoped]] to represent being trapped in a comic book.
* MetaphorIsMyMiddleName
* MeaningfulName: Elsa is the name of a heroine from Wagner's operas, who was [[ShipTease in love with a man]] [[DoesThisRemindYouOfAnything whose face she could never see]].
** Conner's name as well--his first name is the name of an Irish king, and his last, [=McKnight=], is Scottish-English, the name in combination essentially being 'Irish king who is also a warrior'. [[RaceLift Ironically, Disney didn't bother playing with this in casting, and Conner acts VERY American.]]
** Kira's first name means 'Sun, Light', which is appropriate given that she's the Yellow Ranger.
** Ethan's name means 'Strong'.
** 'Anton' is a form of Arthur, as in ''King'' Arthur, and his last name, 'Mercer', means 'son of Mercury'...or, weirdly enough, 'shopkeeper\merchant'.
* MindRape: Mesogog does this to keep his subordinates in line.
* MilestoneCelebration: The 500th episode "Legacy of Power".
** Also, "Fighting Spirit" aired on the 11th anniversary of the show's premiere.
* MixAndMatchCritters: Most of Mesogog's monsters, courtesy of his Geno-Randomizer.
* MundaneUtility: In "Disappearing Act", the Rangers use their high-tech surveillance system to watch Ethan on his date that they prepped him for; and Tommy uses his invisibility to help out.
* MythologyGag: Tons.
** Tommy is usually the culprit. He keeps [[Franchise/SuperSentai Sentai]] logos and MMPR publicity pictures on file and before suiting up as the Black Brachio Ranger, the Rangers found him suspiciously familiar with how all this stuff works. He even said at one time "If there's something I've learnt by being a Power Ranger is that [[Film/MightyMorphinPowerRangersTheMovie everything is possible]]."
** The biggest gag is probably when the PowerTrio spent all of "Lost And Found In Translation" watching a dubbed episode of ''Abaranger'' (bad Hong Kong translations and all!)
** And Connor says his twin brother went to the [[Series/PowerRangersNinjaStorm Wind Ninja Academy]]. It was really funny in context.
* NiceJobFixingItVillain: So Elsa, how did handing out detentions work out for you?
** To be fair, it actually ''did'' work out for her, since it led to her ultimately [[spoiler: being freed from Mesogog's control and able to lead a normal life.]]
** Zeltrax's attempts to frame the White Ranger for trashing Mesogog's lab directly led to the evil being removed from Trent's Dino Gem.
** See LiteralSplitPersonality above.
* NoCelebritiesWereHarmed: The ShowWithinAShow ''Ocean Alert'' from the episode of the same name is clearly the Rangerverse version of ''{{Baywatch}}''.
* NotHimself: All the teens have an attitude adjustment in "Leader of the Whack": Conner's the nerd and Ethan's the jock, Kira's a prissy girly-girl, Devin's a ladies' man and Cassidy's a ShrinkingViolet.
* NotQuiteDead: [[spoiler: Mesogog]] shows up for one more fight at the end of the season, causing the Rangers to lose their powers.
* OhCrapThereAreFanficsOfUs[=/=]WhoWouldWantToWatchUs: "Lost and Found in Translation"
* OlderAndWiser: Tommy
* OlderThanTheyLook: Jeffrey Parazzo was ''26'' when he played Trent, and Jason David Frank looked a quite bit younger than ''his'' actual age during filming, too (31).
** Jason's (Tommy's) case is actually [[LampshadeHanging Lampshaded]] by Cassidy in the first episode when she questions whether he's old enough to be a teacher. Tommy responds by saying 'I can assure you, I'm old enough'.
* OmnidisciplinaryScientist: Averted with Tommy... by applying it to Hayley:
-->'''Hayley:''' Tommy's good with dinosaurs and fossils, but [[ThisAintRocketSurgery a rocket scientist? He ain't.]]
-->'''Conner:''' And lemme guess: you are?
-->'''Hayley:''' Among other things.
* PercussiveMaintenance: Played with in "Legacy of Power", as Conner accidentally kicking the computer makes it look like it crashes at first, but ultimately seems to help. Then in "Game On", Conner being thrown into another computer serves to pull Ethan and Kira out of the game world they were trapped in.
* PhlebotinumKilledTheDinosaurs: More like "What Killed The Dinosaurs Became Phlebotinum", but eh...
* PortalNetwork: Mesogog's invisiportals.
* PowerIncontinence: Tommy gets encased in amber just as he's about to [[spoiler: tell the others that Trent is the then-evil White Ranger]]. When the Rangers manage to free him, he's stuck in Ranger mode. Then when he gets out of ''that'', he becomes invisible. Then he falls into a ''coma''. FourIsDeath, indeed (he finally gets better in "Fighting Spirit").
* PowerWalk: in "Back In Black" - only the Rangers [[SubvertedTrope stop in their tracks]] when Hayley tells them about [[AndAnotherThing Mesogog's deadly firewall]]. Complete with RecordScratch to stop the music.
-->'''Hayley:''' "Did I forget to mention that?"
-->(the Rangers, Conner in particular, give her a look)
-->'''Hayley (sheepishly):''' "I... take that as a 'yes'."
* PrecisionGuidedBoomerang: the Thundersaurus Megazord's Pterarang
* ProfessorGuineaPig: Mercer
* PropheciesRhymeAllTheTime: "Tutenhawken's Curse"
* PutOnABus: Zeltrax disappears and is presumed destroyed after a climactic battle with Tommy in "A Star Is Torn". He reappears in "The Passion of Conner" and "Isn't it Lava-ly", but as he's now gone rogue from Mesogog's forces he then lies low until the finale.
* ReadingsAreOffTheScale: When Tommy first detects the White Dino Gem, he explains that his power readings were so high his equipment couldn't measure it.
* RedHerring: Hints keep occuring that Mercer is actually TheDragon, Zeltrax. But [[spoiler:he's actually the BigBad, Mesogog.]]
** Alternately, the hints are that Mercer is Mesogog himself. [[spoiler:True ''only'' in a technical sense; while they share a body Mercer is actually good and fighting Mesogog.]]
* ReedRichardsIsUseless: The fact that Hayley has such an intellectual ability, and yet is only the owner of an internet café (to whoever's looking from the outside, at least) is rather baffling.
* RefusalOfTheCall: Kira in the premiere; Conner in the second episode. Neither sticks.
* ResistanceIsFutile: Zeltrax gives the line to a kidnapped actress. "Hey, I was up for that part!"
* RivalTurnedEvil: Zeltrax is actually [[spoiler: Tommy's old colleague/friend Smitty, who is never mentioned until the episode where Zeltrax is unmasked)]].
* RoleReprisal: To start, Jason David Frank reprised his role of Tommy, and later, with the resumption of teamups, Pua Magasiva, Sally Martin, Glenn [=McMillan=], Adam Tuominen, Jorgito Vargas Jr., Jason Chan, Katrina Browne, Katrina Devine and Grant McFarland all reprising their roles from ''Ninja Storm''.
* SameCharacterButDifferent: Tommy. A doctor of paleontology? Really?
* SarcasticClapping: Ethan to a dance monster in "In Your Dreams".
* SealedCastInAMultipack: Although the series didn't focus on them as much as other examples, it did this with the scattered Dinozords.
* ShipSinking: Not in the series itself but due to the fact Tommy is single, he's obviously not with Kimberly or Kat
* ShipTease: Kira and Trent, as well as Anton and Elsa in the finale.
* ShoutOut: Two episodes (the fifth, "Back in Black", where Tommy returns to duty, and the two-parter finale, "Thunder Struck") are named after [[Music/{{ACDC}} AC/DC]] song titles, for some reason.
** [[RuleOfCool You need a reason?]]
** It's a bit of a stretch, but the Funky Fisherman, and his sidekick the giant talking fish, are nautically-themed children's characters. [[SpongebobSquarepants Only one other example springs to mind...]]
** The Dino Thunder logo, designed by Tommy, is presumably awfully similar to a certain Dragonzord symbol that he once wore...
** Dragon War, a card game that uses many similarities to both "War" and ''TabletopGame/YuGiOh''. Two notable ones are the Magic Arrow card, and the Ruby Dragon card. The former looks quite a lot like the Living Arrow card. The latter is the most powerful card, and happens to have the same coloring as Osiris/Slifer, one of the Egyptian God Cards (and just as powerful).
* SlidingScaleOfIdealismVersusCynicism: ''Dino Thunder'' in general outlook is basically the first season of ''[[Series/MightyMorphinPowerRangers Mighty Morphin']]'' pushed a bit further towards the Cynicism side.
* SomethingCompletelyDifferent: Rather than adapting an ''Abaranger'' episode, "Lost And Found In Translation" ''is'' an ''Abaranger'' episode, with the U.S. Rangers as a framing device (they even use snippets of the ''Abaranger'' theme in the background!).
* SpellMyNameWithAnS: Fans use both Conner and Connor. In-show, he specifically tells one person "Conner with an E-R".
* SssssnakeTalk: Mesogog
* StealthInsult: During the ''Ninja Storm'' teamup, Mesogog greets Lothor with "Your reputation precedes you." (consider the above-mentioned ContinuityNod from the premiere.)
* StormingTheCastle: The Rangers, Hayley, and a ''Mack truck'' attack Mesogog's island fortress [[spoiler: while Trent rescues Anton.]] It even happens at the same time as [[AllYourBaseAreBelongToUs Zeltrax is trashing the Dino Lab.]]
* StrappedToAnOperatingTable: Tommy in "Legacy of Power". Kira in the premiere. Trent, too, and even to himself (well actually, Anton Mercer) at one point. Don't forget [[spoiler:Elsa in the finale.]] Mesogog ''really likes'' doing this to people.
* StupidSacrifice: Sacrificing the Zords at the end of the season when there were still more options.
* SuchALovelyNoun: Trent to Elsa in "House of Cards" after she blew her cover. She throws the fact that [[spoiler:the other Rangers don't know that Mesogog is Anton]] right back at him.
* SuspiciouslyAproposMusic: Pay attention to the end of "Beneath The Surface", just after Principal Randall shoots down Tommy's advances - you can hear the opening bars of "Where Is The Love" by the {{Black Eyed Peas}} in the background.
* TechnicolorScience: Mesogog's lab has entire racks of specimen jars with brightly colored fluids.
* ThatManIsDead: Zeltrax about [[spoiler: Smitty]]
* TheyWouldCutYouUp: Before the kids learn just who Tommy is, this is the reason Ethan gives to Kira for keeping the gems a secret. Guys with super-powers often end up in labs with wires sticking out of their heads. Conner adds that even ''he'' knows that one.
* ThisIsADrill: The Thundersaurus Megazord's Dino Drill
** The Ankylozord provides a second by replacing the right arm.
* ThisIsWrongOnSoManyLevels: Ethan's opinion of a life-sucking donkey monster in "Diva in Distress".
* ThoseTwoGuys: Aspiring news anchor Cassidy and her cameraman Devin, classmates of Conner, Kira, and Ethan and student of Tommy.
* TriangRelations: Kinda {{Subtext}}-y, but Zeltrax has a thing for Elsa, who has a thing for Tommy, sometimes. And Elsa later has a thing with Mercer.
** And a disturbing version of that subtext with Elsa/Mesogog. From the [[WhatDoYouMeanItsForKids first episode]].
* TVGenius: Ethan.
* TwoTeacherSchool: More like two teacher ''city''. When one of the teachers was incapacitated, they had to ''hire a local millionaire scientist'' to teach his science class, rather than an, I dunno, substitute teacher or something.
** Well, a lot of that was probably Randall's doing in favoring Mesogog's alter ego, but the point does still stand. Perhaps Anton was doing it on a discount ForScience.
* WhosWatchingTheStore: Hayley runs the LocalHangout, but it's open/closed or she's available as the plot demands.
* WidgetSeries: When Hayley gets a satellite TV installed in the cafe, what is the first thing the three Rangers watch? [[spoiler: ''Abaranger'']]
* WorldOfCardboardSpeech: In "Fighting Spirit", Tommy underwent a dream sequence where he had to fight prior Ranger incarnations of himself. It was apparently a lesson that his true power was never with the Power Coins, Zeo Crystal or even the Dino Gems, but it was his will to survive. Of course, being ''Power Rangers'', this metaphorical power allowed him to unlock his [[SuperMode Super Dino Mode]].
* WrittenInInfirmity: Jason David Frank couldn't be on set for the full season, so they [[PowerIncontinence worked around it]] by first "fossilizing" Dr. O in amber (at the end of "White Thunder, pt. 3"), then keeping him stuck in his Ranger suit (at the end of "Leader of the Whack", for ''10 episodes''), then turning him invisible (in "Disappearing Act") - for a total of 13 episodes (he came back in "Fighting Spirit").
* YouGetMeCoffee: The Funky Fisherman
* YouLookFamiliar: Katrina Devine, who was Marah in ''Ninja Storm'' and Cassidy in ''Dino Thunder''. Lampshaded in the crossover:
-->'''Both:''' That girl was so stunning! But ''I'' am so much prettier!
** James Napier as Conner in ''Dino Thunder'' and wannabe ninja Eric in the finale of ''Ninja Storm''. Lampshaded in "Legacy of Power", when Conner is the one who initially brings up Ninja Storm, and explains that he has a twin brother who briefly enrolled at the Wind Ninja Academy before dropping out. Strangely, the Ninja Rangers don't spot the resemblance.
* YourSizeMayVary: The Brachiozord.
