* CreatorKiller: Not to Disney itself, but despite being a box office success, The Secret Lab (the special effects company that Disney made to produce this film) was shut down, with the only other project they made being ''Wild Life'' (specifically, they were animating it). This was [[http://disney.wikia.com/wiki/Wild_Life cancelled]]. More on The Secret Lab's history can be found on a Jim Hill [[http://jimhillmedia.com/columnists1/b/floyd_norman/archive/2006/02/21/1435.aspx article]].
* FanNickname: [[WesternAnimation/TheLandBeforeTime Ozzy and Strut]] for the two ''Oviraptors'' that fight over Aladar's egg.
* PlayingAgainstType: Whoever knew Samuel E. Wright, the voice of the [[JerkWithAHeartOfGold Softshell-hearted crab]] [[Disney/TheLittleMermaid Sebastian]] could play a rude total jerk-ass demanding iguanadon, with almost nothing redeeming about him?
* ScienceMarchesOn: Oviraptors were assumed to be nest raiders when they were first discovered, and named appropriately. Then it turned out, thanks to new technology, that the eggs they are usually found with contain baby ''Oviraptor''. This discovery was made several years ''before'' the movie. However, this discovery does not completely rule out the inclusion of eggs in an ''Oviraptor'''s diet. Recent research has however, revealed ''Oviraptor'' nests, containing embryonic bones from other species, as well as its own, suggesting that it may have eaten eggs after all...
** The ''Pteranodon'', despite being accurate for its time, is shown dip-feeding (snatching food from the water with its beak) and rearing its young like birds. In recent years, its been proven that ''Pteranodon'' would be more likely to catch food by swimming (its prey was noted to be rather small, so dip-feeding would have been impractical) and that baby pterosaurs would have been able to take care of themselves when they were born.

* ''Dinosaur'' has the honor of being the very first film from Creator/WaltDisneyHomeVideo to be released on UsefulNotes/BluRay format in 2006. The film's animation was presumably the reason it was put on the then-new High Definition format first. This Blu-ray at least retained the original 2001 Walt Disney Home Entertainment logo, but the Blu-rays replaced it the next year with the "There is only one Disney" opening. This Blu-ray also has the industry-wide Blu-ray logo on it; the Disney Blu-ray logo was created in 2008.
