List of scientific errors

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.
