This is the list of scientific errors in this documentary. Though it was accurate for its time, and many of the errors in this list were only made errors after the show aired, there are still a few issues.

"White Tip's Journey"[]

  • The episode takes place 80 million years ago but all the creatures in it didn't appear until 5 million years later.
  • Velociraptor and Oviraptor are sometimes (though usually not) shown with pronated hands; this would break their wrist bones.
  • Oviraptor is portrayed as being twice the size of Velociraptor. In reality, Oviraptor was only five feet in length as an adult, thus it was about the same size as Velociraptor.
  • Oviraptor is portrayed as a predator that terrified Velociraptor. In reality, it would have actually been the prey of Velociraptor, as Velociraptor is thought to have been the apex predator of the Djadochta Formation.
  • Velociraptor is briefly said to weigh 100 pounds. In reality, it would have been 33 pounds in weight.
  • Velociraptor were not pack hunters.
  • Male Velociraptor were responsible for incubating eggs and young Velociraptor most likely hunted food by themselves rather than were fed by their parents.
  • Although the Velociraptors are depicted with feathers they aren't feathered enough. Most of their heads should be feathered with only the snout being scaly and the wings should be larger.
  • Prenocephale lived in the Nemegt Formation instead of the Djadochta Formation, so it would not have met Velociraptor in real life.
  • Prenocephale would have also kicked each other with their feet while fighting, similar to modern kangaroos.

"Pod's Travels"[]

  • The episode depicts Europe with grass when grass only existed in India during that time.
  • Pyroraptors were sometimes (though usually not) shown with pronated hands; this would break their wrist bones. They also didn’t use their claws to slash open their prey or enemies as it is now believed that dromaeosaurs used their claws to hold onto their prey while their teeth did the killing (although Pod doesn’t kill a prey dinosaur; he only kills a dwarf Tarascosaurus).
  • The dwarf Dromaeosaurs are seen attacking a larger dwarf Rhabdodon when Raptors most likely didn't attack prey twice their size. They also attack it in a very inaccurate way, using their claws to slash open their prey and wound it when paleontologists now believe their claws were used to hold onto their prey while the teeth did the killing. This method has been called raptor prey restraint.
  • Allodaposuchus are known to look closer to modern alligators than notosuchians.
    • Ironically, the model of Allodaposuchus even uses the Notosuchus model.
  • The model of the "Titanosaur" (presumably Ampelosaurus) model is too similar to a Saltasaurus; it should have a less stiff neck like Diplodocids and other similar sauropods and a slightly taller head.
    • The same is true with Magyarosaurus, which should look like a miniature Alamosaurus.
  • Dwarf Tarascosaurus most likely did not exist.).
    • Even if it did exist, it wouldn't be the top predator, as a pterosaur Hatzegopteryx is currently thought to have occupied this niche (though it had only been named while Dinosaur Planet was midway through production).
    • Both dwarf Tarascosaurus and mainland Tarascosaurus didn't roar. They instead made low-frequency rumbles with their mouths closed, much like cassowaries. This was not known at the time of production, however.
  • A Plesiosaur's neck wasn't very bendy
    • It also had a fluke on its tail as recent Plesiosaur fossils had confirmed.
    • It likely didn't attack land animals and would have ignored dinosaurs and feed completely on fish instead.
  • Iguanodon didn't exist in the Late Cretaceous, however the actual anatomy is based on Rhabdodon; it's simply referred to as Iguanodon for unknown reasons.
  • The Rhabodon are very shrinkwrapped.
  • Both the Rhabdodon and the dwarf Rhabdodon are shown running on all fours. In reality, both Rhabdodon and dwarf Rhabdodon ran on two legs only.
  • Troodonts like Elopteryx were actually omnivores, not pure carnivores.
    • Elopteryx were sometimes (though usually not) shown with pronated hands; this would break their wrist bones.

"Little Das' Hunt"[]

  • This episode depicts Montana with grass when grass only existed in India at the time.
  • Quetzalcoatlus was not the last pterosaur, as Hatzegopteryx and some Nyctosauridae species also lived until the K-T extinction occurred.
    • Quetzalcoatlus has a slightly inaccurate shape.
    • They did not live during the Campanian when the episode takes place and they instead lived during the Maastrichtian 68 to 66 million years ago.
    • They lack pycnofibers which is something all pterosaurs most likely had.
    • They are portrayed to be fish eaters when paleontologists believe they ate small dinosaurs.
  • Troodon were actually omnivores, not pure carnivores.
    • Troodon were sometimes (though usually not) shown with pronated hands; this would break their wrist bones.
  • Maiasaura had a slighty incorrect model.
    • Strangely, all the Maiasaura, but especially seen in Buck and Blaze, are portrayed running on all fours, rearing up only to feed on tree-branches. In reality, Maiasaura would run on two legs only.
    • They are very shrink wrapped, especially on the front legs, when they should have more muscle on the bones.
    • The juveniles have the same proportions as the adults when in real life they would have had very different proportions.
  • The hands of Daspletosaurus shouldn't be pronated (there are some shots where their hands aren't pronated).
  • The model of Edmontosaurus is too similar to that of a Maiasaura.
    • Edmontosaurus did not evolve from Maiasaura either.
  • Daspletosaurus and Tyrannosaurus young were likely covered in some feathers
  • Both tyrannosaurids would make crocodilian and bird sounds like in real life instead of mammalian roars. However, this also was not known at the time of production.
  • Both Daspletosaurus and Tyrannosaurus packs were led by males.
  • The juvenile tyrannosaurids have the same proportions as the adults when fossil evidence shows they had very different proportions.
  • Daspletosaurus did not evolve into Tyrannosaurus .

"Alpha's Egg"[]

  • This episode depicts Patagonia with grass when grass only existed in India at the time.
  • The neck of Saltasaurus was not actually as stiff as shown in the program; its neck was actually very much like a Diplodocid.
  • Saltasaurus likely stood on its back legs, rearing to use its front legs to crush predators with its weight, as some evidence shows.
  • Saltasaurus did not live in the Campanian 80 millions years ago. Instead it lived during the Maastrichtian at the end of the Cretaceous about 68 to 66 million years ago. This also means it did not live alongside Aucasaurus (though it did live alongside another abelisaurid Carnotaurus which was oringially going to be in this documentary. However, a Carnotaurus skull is seen during some of the paleontology segments. Saltasaurus lived alongside Quilmesaurus instead). A possible replacement should be Neuquensaurus, which did live alongside Aucasaurus.
  • The osteoderms on the Saltasaurus aren't pronounced enough.
  • The front feet of the Saltasaurs resemble too much like an elephant's front feet when their toes should be longer and flat on the ground with one long toe sticking out.
  • The Aucasaurs and the Saltasaurs are portrayed to be the same height when in real life Saltasaurus was taller than Aucasaurus.
  • Aucasaurus may have used closed-mouth vocalization instead of roars, but this was not known at the time when Dinosaur Planet was in production.
  • Aucasaurus most likely did not hunt in packs; instead, they were solitary for the most part, occasionally hunting together to bring down difficult prey animals and to scavenge, much like Komodo dragons. This would mean that individual Aucasaurus would have been fairly aggressive towards each other after a hunt ended.
  • Alvarezsaurus did not live in the Campanian 80 million years ago. It lived in the Santonian about 85 million years ago.
  • Notosuchus probably had a short trunk like a pig or a peccary, but this is still being studied.
    • Notosuchus lived five million years earlier than shown in the series.
  • Carcharodontosaurs are depicted as very slow-moving, when it was more likely that they would have been able to chase prey.
    • The brown Carcharodontosaur crushes the neck of the old female Saltasaurus, something that was likely impossible for it to do. In reality, carcharodontosaurs would have delivered bites that caused significant blood-loss, causing the prey to bleed to death.
    • In real life, Carcharodontosaurs did not roar; instead, they may have hissed and growled like alligators and boomed like modern ostriches and bitterns. It’s also possible that they communicated using infrasound.
    • They are quite shrinkwrapped, especially in the neck making their heads appear really large compared to the rest of the body, when they should have more muscle.
