The program's depiction of the Ankylosaurus and Quetzalcuatlus have both been based on models that by now have become outdated.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.
