* SugarWiki/AwesomeMusic: The show has a truly great soundtrack, especially the [[https://www.youtube.com/watch?v=eVIfM7VdviM main theme]], which will give you goosebumps from hearing it. Who knew Dave Hummel was such a great composer?
* NightmareFuel: The episode Dawn of the Cats has a brief segment discussing the decay that would follow a saber-toothed cat carcass after its death in the La Brea Tar Pits; the narrator's descriptions of blowflies laying their eggs in the carcass and picking its bones clean, with accompanying imagery showing just that coupled with unsettling music, may be quite unnerving.
* SpecialEffectFailure:
** Very evident throughout, as the frequently shown animatronic dinosaurs were all pretty obviously choppily-moving models, but hey, this was no big-budget Hollywood production, and they're still more lifelike than the show's early attempts at CGI, and of course the laughable dinosaur handpuppets and static figurines being moved in front of the camera in the later seasons.
** "Valley of the Uglies" reuses animation from ''The Velvet Claw'' and when showing ''Hyaenodon'', they repurpose animation depicting ''Andrewsarchus'' ([[ScienceMarchesOn then envisioned as a mesonychid]]), resulting in ''Hyaenodon'' being shown with primitive ''hooves''.
