''Clash of the Dinosaurs'' (2009) is one of Creator/DiscoveryChannel's many dinosaur-related [[{{Documentary}} documentaries]]. It was presented in a MiniSeries format, and contained a grand total of four hour-long episodes. Each concentrated on different aspects of the dinosaur lifestyle, such as how they coped with environmental changes, how they hunted and defended themselves, and how they reproduced.

The show received notoriety even before its TV debut, thanks to the heavy advertising campaign the TV station gave it. When it finally aired, it quickly gained a [[HypeBacklash bad reputation]] due to the several serious problems that plagued it. Besides its criminal overuse of ([[VisualEffectsOfAwesome admittedly pretty]]) StockFootage, ''Clash of the Dinosaurs'' infamously ''[[QuoteMine quote-mined]]'' paleontology expert Mathew Wedel who appeared on it, and presented wild theories as solid facts. Thanks to these shortcomings, the program is nowadays considered by dinosaur fanatics to be one of the worst [[ArtisticLicensePaleontology dino-documentaries]] of recent times, and the offended scientist actually [[http://svpow.wordpress.com/2009/12/15/lies-damned-lies-and-clash-of-the-dinosaurs/ encouraged his fellow paleontologists to boycott the production company]].

The series was followed by a special titled ''The Last Day of the Dinosaurs''. This time, the producers told us their story of [[ExactlyWhatItSaysOnTheTin how these majestic creatures went extinct]]. This one had fewer problems.
!!A list of tropes that appear in the series:

* AluminumChristmasTrees: While the the criticism for the UV seeing ''Quetzalcoatlus'' is warranted (as there's no evidence of such a thing in the fossil record), some less science minded folks tend to write it off as some fanciful, if not supernatural, creation of the writers with no basis in fact. In actuality, many birds can indeed see in ultraviolet and many raptorial birds like kestrels employ this as a hunting strategy in much the same way the ''Quetzalcoatlus'' is erroneously depicted as doing.
* AnachronismStew: Easily avoided, since not that many animals appear, and the ones that do were contemporaries in RealLife.
** Actually, the program implies that ''[[UsefulNotes/StockDinosaursTrueDinosaurs Deinonychus]]'' fed on juvenile [[UsefulNotes/StockDinosaursTrueDinosaurs tyrannosaurs]], while there was a 30-million year gap between the two.
* ApocalypseHow: A ApocalypseHow/{{Class4}} event.
* ArsonMurderAndJaywalking: Poor Mathew Wedel. He wasn't only quote-mined on national TV, his helpful emails explaining dinosaur science dismissed by the creators and nearly made a fool in the eyes of his colleagues... the bastards even misspelled his name on screen!
* ArtisticLicensePaleontology:
** To clarify that quote-mining part: the expert was trying to clear up the misconception that large dinosaurs had two brains (one in their head, one in their hip-region). The editors made it sound like he was confirming the notion.
** What more, he clearly said that [[UsefulNotes/StockDinosaursTrueDinosaurs sauropods]] most likely covered their eggs with vegetation. The CGI clip shows a sauropod leaving its eggs ''out in the open''.
** When their eggs hatch, the young sauropods and [[UsefulNotes/StockDinosaursTrueDinosaurs tyrannosaurids]] look exactly the same as the adults. "[[Series/WalkingWithDinosaurs Sauropodlets]]" and "[[Series/DinosaurRevolution rexlings]]" actually had way different body proportions.
** Their [[MeaningfulName duck-billed]] [[UsefulNotes/StockDinosaursTrueDinosaurs dinosaurs]] have fleshy lips.
** While the [[UsefulNotes/StockDinosaursTrueDinosaurs raptors]] were nice and feathered, they still weren't quite feathered ''enough''. Also, the broken wrists.
** Recycling of animation models meant that the lean troodontid ''[[UsefulNotes/PrehistoricLifeBirdlikeTheropods Saurornithoides]]'' looked the same as the relatively robust dromaeosaurid ''[[UsefulNotes/StockDinosaursTrueDinosaurs Deinonychus]]''.
** ''Quetzalcoatlus'' being depicted as an aerial hunter that searches for prey using UV-seeking vision like a kestrel. While ''Quetzalcoatlus'' most likely did have very keen eyesight and the flight abilities for giant azhdarchids are looking better than they ever have before, it's highly unlikely that any azhdarchid did most of its hunting in flight nor had UV-seeking vision. Instead, it more likely hunted on the ground like a stork. Additionally, it's depicted as being covered in scales rather than the fuzz it was covered with in life.
* BewareMyStingerTail: ''Ankylosaurus''.
* BlatantLies: To quote [[http://www.foxnews.com/story/0,2933,579519,00.html?test=faces executive producer Bill Howard]]:
-->"The series sets out to gather the sum total of today's paleontology and scientific knowledge about dinosaurs, letting viewers see what these creatures were like as animals, not {{prehistoric monster}}s."
* CrapsackWorld: The end of the Mesozoic.
* CurbStompBattle: To paraphrase one talking head, using his hands to represent dinosaurs:
-->(in high voice) "Hi, I'm a ''[[UsefulNotes/StockDinosaursTrueDinosaurs Deinonychus]]''!"\\
(in low voice) "Hi, I'm a ''[[UsefulNotes/PrehistoricLifeSauropods Sauroposeidon]]''!"\\
(squishing motion)
* EatsBabies: ''[[StockDinosaursNonDinosaurs Quetzalcoatlus]]'' and ''[[UsefulNotes/StockDinosaursTrueDinosaurs Deinonychus]]''.
* EverythingsBetterWithDinosaurs: Goes without saying.
* EyeScream: The ''[[UsefulNotes/StockDinosaursTrueDinosaurs Triceratops]]'' stabs the ''[[UsefulNotes/StockDinosaursTrueDinosaurs Tyrannosaurus]]'' in the eye.
* FeatheredFiend: ''[[UsefulNotes/StockDinosaursTrueDinosaurs Deinonychus]]''. And it's actually shown ''[[ShownTheirWork feathered]]''.
* ForegoneConclusion: The extinction event at the end of the Cretaceous [[spoiler:[[ItWasHisSled happens]]]].
* GiantFlyer: ''[[STockDinosaursNonDinosaurs Quetzalcoatlus]]''.
* {{Gorn}}: The ''[[UsefulNotes/StockDinosaursTrueDinosaurs Deinonychus]]'' pack attacking the young ''[[UsefulNotes/PrehistoricLifeSauropods Sauroposeidon]]''.
* InfantImmortality: Averted, as the ''[[StockDinosaursNonDinosaurs Quetzalcoatlus]]'' preys on ''[[UsefulNotes/StockDinosaursTrueDinosaurs T. rex]]'' babies.
** Same thing with the ''[[UsefulNotes/StockDinosaursTrueDinosaurs Deinonychus]]'' pair and the young ''[[UsefulNotes/PrehistoricLifeSauropods Sauroposeidon]]''.
* MexicanStandoff: This is what the {{Narrator}} calls the situation the ''Saurornithoides'' and ''Charonosaurus'' find themselves in. The former is trying to steal the latter's egg.
* MisplacedWildlife: The narration suggests that ''Tyrannosaurus'' lived in Asia, when it was strictly North American. To be fair, some include the Asian ''Tarbosaurus'' in the genus, but most (both then & now) consider them distinct.
* OutrunTheFireball: The dinosaurs attempt this. Emphasis on "attempt".
* PaletteSwap: The extinction special has this with any new species they show. They don't even change the color.
** ''Sauroposiedon'' gets cast as ''Alamosaurus''
** ''Deinonychus'' gets cast as ''Saurornithoides'' despite the latter being more closely related to ''Troodon''.
** ''Parasaurolophus'' gets cast as ''Charonosaurus''.
* PrehistoricMonster: Pretty much averted in the original miniseries, but played straight in ''The Last Day'', when food sources became scarce.
* PteroSoarer: A scaly, UV-seeing ''[[StockDinosaursNonDinosaurs Quetzalcoatlus]]''.
** At least they got the quadrupedal launch right. That's about it, unfortunately.
* QuoteMine: Poor, poor Mathew Wedel.
* RaptorAttack: The ''[[UsefulNotes/StockDinosaursTrueDinosaurs Deinonychus]]'' at least have feathers, but are shown killing a ''[[UsefulNotes/PrehistoricLifeSauropods Sauroposeidon]]'' with ridiculous ease.
* RuleOfCool: [[UsefulNotes/StockDinosaursTrueDinosaurs Hadrosaurs]] using a sonic weapon against [[UsefulNotes/StockDinosaursTrueDinosaurs theropods]]? A pair of [[UsefulNotes/StockDinosaursTrueDinosaurs small raptors]] attacking a sub-adult [[UsefulNotes/StockDinosaursTrueDinosaurs sauropod]]? Do note, when the talking head [[note]]The one who was quote-mined, at that![[/note]] said "juvenile sauropod" and "pack of raptors", he meant tiny babies and a huge pack, but the animators instead used the largest animal that would still qualify as a "non-adult" specimen getting mauled by a pair of raptors.
* SeldomSeenSpecies: ''Sauroposeidon'', ''Charonosaurus'' and ''Saurornithoides''.
** Don't forget ''Alamosaurus''! Yes, they reused the ''Sauroposeidon'' model, but who cares?
* ShownTheirWork: Most of the talking head segments. (They ''did'' get actual paleontologists, after all.) The key word being [[QuoteMine most]].
** Feathered [[UsefulNotes/StockDinosaursTrueDinosaurs deinonychosaurs]]. One would be surprised as to how rare they are in media.
** An entire segment is dedicated to the mechanics of ''Quetzalcoatlus''' launching technique. Additionally, while its method of doing so is most likely wrong, the portrayal of it feeding on baby dinosaurs is definitely accurate.
** The ''T. rex'' model is also one of the better ones among other recent CGI'ed reconstructions of the animal. For such a well-known and popular dinosaur, you'd be surprised how often computer modelers mess up its anatomy, especially the shape of the head. That said, there's no excuse for the crocodylian jowls of the show's model.
* SmallTaxonomyPools: You only get six dinosaurs and a PteroSoarer. The special throws in three more dinos.
* SpeculativeDocumentary: Maybe a bit too speculative.
* StockDinosaurs: ''TyrannosaurusRex'', ''Triceratops'', ''Ankylosaurus'', ''Parasaurolophus'', ''Deinonychus'' and ''Quetzalcoatlus''. Sadly, along with the sauropod ''Sauroposeidon'', [[SmallTaxonomyPools those are the only creatures in the doc]].
* StockFootage: It drives a man nuts! The same clips being replayed constantly, over and over and over again!
* TyrannosaurusRex
* ViewersAreGoldfish: To quote the quote-mined paleontologist:
-->"[The program] is incredibly repetitive, to the point that I found it hard to watch for any length of time without my attention wandering. Not just the CGI clips, but the narration as well. You’ll learn in 30 seconds why females tend to be choosier about mates than males (eggs are more expensive than sperm), and spend the next 15 minutes having that slowly beaten in your brain using as much empty verbiage as possible. Ditto every other fact on the show."
