'''''Dinosaurs Decoded''''' is a 2009 TVDocumentary from Creator/NationalGeographicChannel (although in some countries, [[ChannelHop it aired under the]] DiscoveryChannel logo) that focuses on some recent controversial theories concerning [[StockDinosaurs classic dinosaurs]].

Paleontologist Jack Horner and his colleagues explain to the dumbfounded viewers that a ''third'' of their beloved dinosaur kinds [[ScienceMarchesOn they grew up with]] didn't actually exist as valid genera/species, but really represented the different growth stages of a single dinosaur.

!!This series provides examples of:

* AmazingTechnicolorWildlife: The trope befalls ''T. rex'' itself: it is pitch black with a bright red face, similarly colored accents on its back and stripes on its tail.
** Male ''Triceratops'' have bright blue streaks on their body, and their frill is bright yellow with orange patterns on it.
** In a scene near the end of the program, ''Pachycephalosaurus'' is bright blue with an orange dome.
** Finally, there is a ''Dromaeosaurus'' that is blue with white spots. It appears briefly in two or three scenes.
* AnachronismStew: A mild case, what is obviously ''Dromaeosaurus'' is shown living with the later ''Triceratops'', ''Pachycephalosaurus'' and ''Tyrannosaurus''.
* ArtisticLicenseBiology: To quote Horner on ''Triceratops'' horns, "The last place you want a defense organ is on your head". Evidently, he's never heard of rhinos, buffalo, bison, goats, deer, antelope, etc.
* ArtisticLicensePaleontology: Needless to say, not everyone agrees with Horner's theories and the way he explains them in this program.
* EverythingsBetterWithDinosaurs
* FeatheredFiend: The aforementioned ''Dromaeosaurus''.
* LeaningOnTheFourthWall: At one point, a juvenile ''Triceratops'' comes up and looks at the camera.
* RaptorAttack: The ''Dromaeosaurus'' that briefly appears lacks primary feathers.
* RealIsBrown: Averted.
* ShownTheirWork: Of course. The bulk of the program is paleontologists explaining stuff.
* StockDinosaurs: ''T. rex'' (said to be the same as ''Nanotyrannus''), ''Triceratops'' (same as ''Torosaurus'') and ''Pachycephalosaurus'' (merged with ''Dracorex'' and ''Stygimoloch'').
* StockFootage: Scenes from ''TheTruthAboutKillerDinosaurs'' appear.
* TyrannosaurusRex
* UseYourHead: It's said that ceratopsians and pachycephalosaurs did not do this, contrary to popular belief.
