- He Also Did: Craig Bartlett is also the creator of Hey Arnold! and Ready Jet Go!.
- The Merch: It exists, but a lot of it is poorly reviewed and said to be shoddily made.
- The Other Darrin: Buddy has had three voice actors (Phillip Corlett for seasons 1 and 2, Sean Thomas in season 3, and Dayton Wall in season 4).
- In Season 3, Joey Silva replaces Alexander Matthew Marr as Don.
- Relationship Voice Actor: Mr. Conductor and Tiny Pteranodon are voiced by the father daughter duo of Ian James Corlett and Claire Corlett. Buddy's first voice actor was her brother Phillip.
- Science Marches On: The show does its best to stay on top of current discoveries, but sometimes it finds itself the victim of this.
- For starters, Eoraptor might not be a theropod, but a sauropod ancestor.
- Stygimoloch may not represent a distinct creature after all, but the subadult form of Pachycephalosaurus. Whether or not it is different, young pachycephalosaurs probably had flat (if somewhat knobbly) heads, growing domes as they aged◊.
- Brachiosaurus never lived in Africa. That was Giraffatitan.
- Recent studies show ceratopsians might have had quills on their backs.
- The character design of Sunny Sauroposeidon is clearly based on brachiosaurids a group that the taxon probably doesn't belong to after all, instead being more related to titanosaurs. Granted, the largest macronarians would have had a brachiosaur-like appearance.
- Adult ornithomimosaurs are now known to likely have had wings of some sort.
- The limb proportions of Spinosaurus were probably far more unusual than depicted in the show.
- The discovery that Dimetrodon may have been nocturnal casts doubt on the idea that its sail was primarily used for thermoregulation.
- The giant Shonisaurus material has been reassigned to Shastasaurus.
- She's a Man in Japan: Tiny is a boy in the Czech dub.
- Talking to Himself: This happens in "Spooky Tree", where Shiny and Annie interact. Shiny and Annie have the same voice actress, Erika-Shaye Gair.
- Un-Canceled: The show initially got cancelled after the season 4 finale movie, What's At the Center of the Earth?. Craig Bartlett revealed in a Reddit AMA, that PBS revived the show for 11 more episodes, bringing the total episode count to 100. This was officially announced on October 2, 2018.
