* In ''Journey to Chandara'', James Gurney states that Dinotopia no longer appears on modern maps. The manner in which he says so implies that the island no longer exists.
** More likely he meant it is simply long forgotten by the rest of the world (it is a LostWorld, after all). Maybe like in the animated film, [[HesJustHiding it's just hiding]]. Or it could even be a PocketDimension.

* All the dinosaurs are referred to by the names given to them by the mainstream scientific community (despite the island being completely isolated from that community)... including the ones that haven't yet been discovered and named at the time the books are set in.
** Not the only terms either; words such as "taxi" and "helium" didn't exist yet either.
** The Dinotopians are probably using whatever words the specific species of animals are using for themselves, so we could probably consider this a TranslationConvention.
*** The fact that the Latin translation of ''Tyrannosaurus rex'' is a minor plot point in ''The World Beneath'' rules out TranslationConvention. Denison also expresses fear of them -- in 1862, four decades before the species was named.
*** It gets even more confusing in the prequel novel ''First Flight.'' In it, we're introduced to "Northies", or ''Quetzalcoatlus northrop''. This species was named after Jack Northrop, meaning that the Dinotopians somehow know the name of an animal named after ''a person who wasn't even born yet!''
* Dinotopians use leathers, skins, furs, and [[ImaHumanitarian other]] [[HumanResources animal products]] were seen in use by the Dinotopians. In Journey to Chandara it's explained when Arthur Dennison is given a new journal bound in the skin of an IntellectualAnimal "whose dying wish was to donate his body to science".
** There must be a larger variety of things that the [[TalkingAnimal dinosaurs]] can donate their bodies to: [[ForScience Science]], one of several causes that [[HumanResources need the materials for building]], and [[ImaHumanitarian Culinary]]. Humans can only donate their bodies [[ForScience for scientific uses]].
