- Why is there so much Misplaced Wildlife in "New Blood"? Because it takes place in the Triassic, which was when all the continents were merged into one giant continent!
- Why are there so many non-dinosaurian animals in "New Blood"? The narrator simply notes that dinosaurs are not yet very common. At the time the idea that dinosaurs weren't actually very common nor dominant during much of the Triassic was only a budding idea. Later research confirmed that for most of the Triassic, dinosaurs shared the world with other animals, like pseudosuchians (crocodile relatives), other reptiles and the remnants of stem-mammals such as dicynodonts. It would not be until the late Triassic when another mass exctinction wiped out almost all of the competition, after which dinosaurs were the best adapted group to rapidly fill the vacant niches.
- "Death of a Dynasty" ends with the famed asteroid, of course. However, it is funny to rewatch years later and notice how many references they made to older theories about the extinction of the dinosaurs, some of which were just bizarre. There is increased vulcanism, glacialism (showcased by the snowy peaks), aridity, flora and insect change as a result of flowers evolving, mammals diversifying and predating on dinosaur eggs, and increased infighting and infanticide of the dinosaurs. It's like the show was telling us: "yes, dinosaurs may be having a bad time, but they would have pulled through all if it wasn't for the damned space rock."
- In the first scene, the male Tyrannosaurus is saved from the deadly fumes because of its large size. At the end, the same beast (and its kind) is killed because it is too large to survive the meteor strike effects.
- The Didelphodon in the sixth episode are as everywhere and as obnoxious as the Coelophysis in the first one, subtly telegraphing that dinosaurs are being replaced in the same way they replaced mammal-like reptiles 160 million years before... and by those reptiles descendants, no less.
The 2013 Movie
- Quetzalcoatlus presence could be weird, given that its fossils were discovered in western United States, while the movie is set in Alaska. However, it could be possible that those Quetzalcoatlus are only temporarily in Alaska. How? Well, scientists believe that azhdarchids like Quetzalcoatlus could have been capable of taking long-distance migrations lasting weeks, which explains their presence in the Alaskan wilderness.
- As mentioned on the Science Marches On page, the species of Pachyrhinosaurus that inhabited the Prince Creek formation (where the movie is allegedly taking place) is classified as Pachyrhinosaurus perotorum while movie showcases Pachyrhinosaurus lakustai, which lived further south in Alberta, Canada. However it's possible that movie isn't only set in Alaska but also takes place in Canada where P. lakustai fossils were found. That way, it could be possible that Patchi's herd feeding grounds are located further south in Canada while their annual migration destination is located in Alaska. This is also Truth in Television: modern migrating animals like wildebeest often cross different countries during their annual migrations
