History Series / MammalsVsDinos

*** ''Stegosaurus'' is stated as being almost 30 feet long. While there is a species of Stego that could grow that big the species depicted is most likely ''Stegosaurus Stenops'' who could only reach a length of about 23 feet.

*** The ''Allosaurus'' is the worst offender of this. Its head is way too small, it lacks the head crests that it's known for having, it's incredibly skinny, its fingers are too small, and it has very incorrect feet.

** ''Microraptor'' is implied to be one of the first Dinosaurs to be able to glide when there was another small dinosaur from the Jurassic Period called ''Archaeopteryx'' that could also glide. It is also implied that the first birds appeared during the Cretaceous period when birds had existed since the Jurassic period, ''Archaeopteryx'' being one of the first.

** It is suggested that juvenile ''Tyrannosaurs'' had feathers and lost them as they grew which is not how feathers work.

** Besides the inclusion of feathers, the juvenile ''Tyrannosaurs'' look almost identical to the adult which, based on fossil evidence, we know was not the case. The narrator even states that they would have looked different.

''Mammals vs. Dinos'' (known as ''In the Shadow of the Dinosaurs'' in European countries), is an obscure documentary mini series, co-produced by Creator/{{NHK}} and the Science Channel, that aired in 2007.

** It is suggested that juvenile ''Tyrannosaurs'' had feathers and lost them as they grew which is really not how feathers work.

** Both the narrator and Dr. Gregory Erickson suggest that the bite force of ''T. rex'' could have been high as 16,000 pounds when 8,000 pounds is a lot more likely to be the maximum force in which a ''Tyrannosaurus'' could bite.

** It is highly unlikely that an entire herd of adult ''Triceratops'' would be scared off by 2 juvenile ''Tyrannosaurs''. They don't even attempt to fight back despite the narrator stating that they are heavily armed.

*** ''Repenomamus'' is said to be 3 feet long but that size is more akin to ''Repenomamus Giganticus'' and not ''Repenomamus Robustus'', which is the species depicted, who could only reach a length of about 1 foot.

** The series get's the reason why Dinosaurs grew so big almost spot on.

** Both the narrator and Dr. Gregory Erickson suggest that the bite force of ''T. Rex'' could have been high as 16,000 pounds when 8,000 pounds is a lot more likely to be the maximum force in which a ''Tyrannosaurus'' could bite.

** ''Tyrannosaurus Rex'' is said to have appeared 70 million years ago when it really appeared 68 million years ago.

* MightyRoar: The ''T. Rex'', they even have the screen shake when it roars.

** ''Stegosaurus'' most likely didn't travel in herds. Stegosaurus also most likely couldn't put blood into its plates to make them look red.

** ''Cimolestes'' is claimed to be the first mammal with a placenta when a much older placental mammal called ''Eomania'', which lived about 125 million years ago during the early Cretaceous, was already known at the time.

** It is suggested that juvenile Tyrannosaurs had feathers and they lost them as they grew which is really not how feathers work.

** Both the narrator and one of the talking heads suggest that the bite force of ''T. rex'' could have been high as 16,000 pounds when 8,000 pounds is a lot more likely to be the maximum force in which a ''Tyrannosaurus'' could bite.

*** ''Repenomamus'' has its legs splayed out like a lizard when it should have them tucked under it's body.

*** ''Dilong'' has a skull that is way too round when it should be a little more pointy.
*** The ''T. rex'' has a very round head when it needs to be more pointed.

*** ''Psittacosaurus'' is said to be 4 feet tall when the largest specimens were only 2 feet tall.

*** ''Tyrannosaurus'' is said to reach a height of almost 20 feet when the largest specimens are no taller than 12-13 feet. If that wasn't bad enough, the European version of the documentary claims Tyrannosaurus was 39 feet tall (perhaps they meant 39 feet long).

** The Triceratops are shown galloping which, considering their large size, would have been physically impossible for them to do.

* {{Expy}}: In the Triassic segment, a ''Placerias'' that looks like a straight rip off of the one from * ''Series/WalkingWithDinosaurs'', same color scheme no less, can be seen.
