* Evidence suggests that ''Stegosaurus'' lived in herds and would have preferred the open savanna regions of the Morrison formation to the more forested areas.

* Biomechanical studies have shown that skim feeding (as ''Rhamphorhynchus'' is shown doing) was not possible in known pterosaurs.

* Biomechanical studies have shown that skim feeding (as ''Rhamphorhynchus'' is shown doing) was not possible in known pterosaurs. ''Rhamphorhynchus'' itself is more likely to have hunted fish while swimming and diving.

* [[http://www.sciencedaily.com/releases/2010/11/101101083150.htm Footprints from a baby bipedal sauropod]] have been recently found: Perhaps [[LandBeforeTime Littlefoot]] and the WWD sauropodlets ''walked on two legs'' and become quadrupedal only when they grew larger (an ancient heritage from their ancestors, the "prosauropods" such as the aforementioned ''[[StockDinosaursTrueDinosaurs Plateosaurus]]'')! However, most paleontologists are skeptical of this interpretation. Even the trackways of adult sauropods often leave just the prints from just one pair of feet, thus is even more likely about the younger ones.

* ''Utahraptor's'' anatomy was extremely different from what we saw on the program. It (like most other dromaeosaurids) had much shorter legs, making it an average runner, a shorter tail (closer to an oviraptorid than a deinonychosaur) and more outward facing teeth.

* The enormously long-necked ''[[UsefulNotes/PrehistoricLifeNonDinosaurianReptiles Tanystropheus]]'' was potrayed as capable of losing and regenerating its tail like a lizard. In the past it was indeed suggested by palaeontologist Rupert Wild[[note]]who also thought that ''Tanystropheus'' was closely related to lizards - nowadays it's generally considered to be more closely related to archosaurs than to lizards[[/note]] that this creature was capable of autotomy, but other scientists who studied its fossils didn't find evidence for that. It has also been portrayed as an accomplished swimmer, but [[http://markwitton-com.blogspot.ca/2015/11/the-lifestyle-of-tanystropheus-part-1.html we don't know for sure if it really was such]] - its body-shape was all but hydrodynamic, and some think ''Tanystropheus'' [[http://markwitton-com.blogspot.ca/2015/12/the-lifestyle-of-tanystropheus-part-2.html was a shore animal who used its neck as a fishing rod]], catching small prey a bit like a heron. Interestingly, the very similar ''Dinocephalosaurus'', which probably was a true swimmer, was discovered a year before the special premiered.

* "Iguana-spike-backed" ''Diplodocus'': Some researchers now argue these spikes were spread across on Diplodocus' back rather than put in a single line as shown in the program.

** However it should be said that this does not mean that the ''Gorgosaurus'' was inaccurate; ''Yutyrannus'' was a more primitive tyrannosaur, and only distantly related to ''Gorgosaurus''.
*** It should ''also'' be noted that phylogenetic bracketing says that ''Gorgosaurus'' and kin were as likely feathered as, say, ''Utahraptor''. And adding ''Tianyulong'' and ''Kulindadromeus'', it's becoming more plausible that ''feathers'' were the original dinosaur skin, and not full-out lizard scales or crocodile scutes.

* ''Entelodon'' was not as closely related to pigs as was believed. It is now thought to be closer to whales and hippos.

* Most [[StockDinosaursTrueDinosaurs coelurosaurs]] certainly had feathers. The several [[StockDinosaursTrueDinosaurs dromaeosaurid species]] surely had them, but in the franchise they are all shown featherless, see further): this, rather than ScienceMarchesOn, might be interpreted more as RuleOfCool, or rather, ArtisticLicensePaleontology, since feathered raptors would have appeared "too cute"? In RealLife dromeosaurids had WING-shaped forelimbs just like their famous relative, the "ur-bird" ''[[StockDinosaursTrueDinosaurs Archaeopteryx]]''...
