Meta guess; In the movie, Alex was meant to talk from the start
The bird is clearly the only major character with a clear cut "personality", even if you remove the dialogue, and his voice matches up best with his mannerisms without detracting from the story—it seems likely that the writers wanted Alex to be the only talking dinosaur at first, but then changed it so that all of the main ones talk. Baryonyx in the original show
Word of God is that Baryonyx was going to appear in "Giant of the Skies", but was cut. Baryonyx was discovered in England, the implied first European stop of the Ornithocheirus in its migration to Spain. This segment is notorious for the misplaced appearance of American Utahraptor, which has led some to assume that Utahraptor replaced Baryonyx in this segment during production. Well, in 1997, when the show was beginning production, a Baryonyx was discovered with fish scales and remains of a young Iguanodon in its gut. And what happens in this segment in the episode? The Ornithocheirus steals fish from a smaller pterosaur, and then watches a Utahraptor pack hunt an Iguanodon. This is the guess: In the original script featuring Baryonyx rather than Utahraptor, Ornithocheirus would steal fish from Baryonyx, and then Baryonyx, being still hungry, would turn to the Iguanodon herd and kill a youngster. Movie guess; Patchi has PSTD after he saw his father being killed by Gorgon.
Movie guess; Patchi's herd nesting grounds are located in Alberta, Canada, while the valley to which they migrate each year is in Alaska.
This could explain why they're Pachyrhinosaurus lakustai despite the movie taking place in location where P. perotorum would've been more appropriate. After all, this type of behaviour (animals crossing over different countries during their migrations) is common amongside various species of herbivores, such as wildebeest
. The reason why T.rex in the series is anatomically incorrect is because of presence of the volcanic activity.
Given the narration stated that increased volcanic activity is choking the dinosaurs' landscape, and supposedly weakened the egg shells of all kinds of dinosaurs, resulting in most hatchlings dying in their eggs or being stillborn, means that it could contribute to appearance of dinosaurs' living in area where "Death of a Dynasty" takes place. Those dinosaurs that did hatch and survive were pretty healthy, but their appearance looked either emaciated or slightly deformed. This explains why rexes from WWD looked a lot more worse for wear than those shown in Prehistoric Park who lived in different part of the region, where there was less volcanic activity and better living conditions. The tie-in book are Early Draft Tie-Ins.
And animals that only appear within it were nearly in the episodes themselves, but were cut.- The Metoposaurs would had shared the Koolasuchus models, but with different color scheme (like for example, light green).
