- 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!
- "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.
