This is the list of scientific errors in this documentary.
The Evolution Winners[]
- Inostrancevia lack teeth covering organs and has green coloration too. Name one mammal that is actually green. No predator like Inostrancevia would have such bright coloration to hide.
- Ischigualastia's model is based on Placerias, a leftover from when it was set to be used, but was used as Ischigualastia due to time constraints. Thus, it didn't have tusks.
- Probelesodon was more than likely to have been omnivorous as its relatives were likely omnivorous. It wasn't also found in the Ischigualasto formation, a replacement would be Chiniquodon.
- Saurosuchus couldn't bound like how it was depicted in the series.
- Eoraptor could have been omnivorous.
- Eoraptor could have also been more feathery like other small theropod dinosaurs. However, this is debated.
- Gigantoraptor was too big to jump.
- Gigantoraptor was discovered in the Iren Dabasu Formation in China. Thus it was not native to Mongolia.
- Tylosaurus, along with other mosasaurs, would have possessed a tail fluke.
- Varanoids did not live in Antarctica 194 million years ago. Arcanosaurus, one of the oldest varanoids is 125 million years old.
- The color scheme of Squalicorax (listed here as Squalicorax because the director says it is that genus, despite what the website says) is unrealistic.
The Watering Hole[]
- Dinheirosaurus may represent a species of Supersaurus.
- Ornitholestes had feathers and its teeth were covered by lips. It would have also had a sickle claw on each of its second toes, similar to a dromaeosaurid. Also, its second toes would have been retractable, due to its classification as a maniraptoromorph, thus making it a true maniraptoran.
- Ornitholestes was not found in Europe, and was endemic to North America.
- Rhamphorhynchus probably didn't drill holes into trees to hunt insects like Cenozoic woodpeckers, this may just be a speculation.
- The model of Miragaia is anatomically incorrect. It should have a longer neck, shorter plates, and spikes running down from the base of the tail to the tip.
- Allosaurus and Torvosaurus could have had lips covering its teeth as recent studies showed.
Survival Tactics[]
- Castorocauda was a docodont, not a mammal. Docodonts are still part of Mammaliaformes, though.
- The real Guanlong was covered with proto-feathers.
- Mamenchisaurus, like other sauropods, was unlikely to be a good swimmer. The theory that sauropods spent their time in water has been debunked.
- Sinraptor never lived alongside Shunosaurus. A better candidate would've been Gasosaurus, Szechuanosaurus, or Yangchuanosaurus.
- The real Rahonavis was a jeholornithid, not a dromaeosaurid as how the program depicted it.
- Rahonavis could have or could have not flown, but no one knows for sure.
- Rahonavis might have or might have not had the ability to vocalize or mimic anything it heard, but this is a speculation.
- It is believed that the true Protoceratops had Psittacosaurus-like quills.
The End Game[]
- The two juvenile T. rex didn't have feathers, unlike the last juvenile T.rex, which still has feathers, but this may have been an episode's programming mistake.
- Tyrannosaurus's teeth in reality were actually most likely covered by lips.
- Tyrannosaurus did not roar but instead made sounds with its mouth shut, much like alligators and bitterns, but this was not known at the time of production.
- The validity of the genus Troodon has been called into question recently, as the type specimen of the genus is a small amount of teeth, which are not diagnostic to the genus level in dinosaurs. The show's version is most likely Pectinodon. However, Troodon has been considered dubious in 2017, 6 years after the show's release. It was moved into the new genus Latenivenatrix and Stenonychosaurus. The latter was once thought to be a synonym of Troodon but is now considered a valid genus.
- Triceratops probably had Psittacosaurus-like quills on its tail, but this is speculation.
- New theories suggest that male T. rexes may have raised the young.
