* CrowningMusicOfAwesome: [[http://www.youtube.com/watch?v=XwIjKvzlZLI See here]] (skip to 1:30)
* {{Fanon}}: It's uncertain whether it is fanon or trolling, but just [[http://en.wikipedia.org/w/index.php?title=Animal_Armageddon&action=history look at the history of Animal Armageddon's Wikipedia page!!!]] Especially the earlier edits.
* NightmareFuel: Arguably [[spoiler:the last episode, in which an asteroid strike nearly wipes out mankind]].
** Several of the BadAss creatures, not to mention the extinctions that wipe them out.
* SpecialEffectsFailure: One of the most common complaints people have against the series. The animal restorations are ugly as sin, and the graphics in general look as if they had been taken from a video game. The animals themselves come from a prehistoric UncannyValley. ''WalkingWithDinosaurs'' this ain't.
* TearJerker: Several of the creature's sad fates in the face of extinction definitely qualify.
** One episode has one of the last two ''{{Tyrannosaurus Rex}}''es kill and eat the other, his brother, then it cuts to him some days later, trying desperately to stay on his feet, knowing if he falls, he's never getting up again. Anybody else flash back to the horse from ''Film/TheNeverEndingStory''?
*** I believe it was his mate, not his brother.
* UncannyValley: Goes hand in hand with the SpecialEffectsFailure.
* VisualEffectsOfAwesome: The recreations of Earth itself and the scenes without any living things. Also, [[http://animal.discovery.com/prehistoric/quetzalcoatlus/ the show's rendition]] of ''Quetzalcoatlus'' is very nice.
