The program's depiction of the Ankylosaurus and Quetzalcuatlus have both been based on models that by now have become outdated. These are not considered errors, since new discoveries have been made since the series had been finished, however it does mean that slowly all of the animal designs that appear in the series are becoming obsolete. The Ankylosaurus didn't have that many plates on its back, for instance, but had fewer, larger plates. Whereas the Quetzalcoatlus had a much, much longer neck, a differently shaped head with a different crest on its skull, and no teeth. It also walked more upright, when on the ground. See more
When the female T. rex kills the Anatotitan, there are no wounds visible on its body, only a mere red spot appears on its side. As the predator bites into the Anatotitan, her head clearly passes into the animal several times. The scene is shot from afar, but this doesn't hide the obvious animation goof. See more
Millions of years of evolution has also created intimate relationships among different types of dinosaurs. Especially the delicate balance between predator...and prey.
