Trivia

 * Beau was originally an one shot character, but his character was developed and became Dee Dee's love interest. Bullet, Robin, Mike and Soyen were also originally one shot characters.
 * The animals in Back from Extinction came from different locations from the time portal. The same multi-part episode also features animals from previous episodes.
 * All dinosaurs and other prehistoric creatures had modern accurate features, such as feathered maniraptors and quadrupedal pterosaurs.
 * The animation in this series is a lot more smoother and fluid than the original shows.
 * Most of the animals can talk to one another, but not to humans. Expect for Bubbles, who has an ability to talk to them. However in Down Under, Dee Dee makes an attempt to talk to the thylacine brothers in their own vocalizations. And then, the thylacines understood her.
 * Each animal vocalization is based on modern animal vocalizations (some of them provided by Frank Welker) such as:
 * Large theropods (Tyrannosaurus, Allosaurus, Spinosaurus, etc.) and prehistoric crocodilians (Deinosuchus, Sarcosuchus, etc.) - Modern crocodilians
 * Most dromaeosaurids (Velociraptor, Dakotaraptor, etc.) and troodontids (Latenivenatrix, Mei, etc.) - Modern birds of prey
 * Halszkaraptor - Modern ducks
 * Ornithomimids (Struthiomimus, Gallimimus, Deinocheirus, etc.) - Modern geese and ratities
 * Sauropods (Brachiosaurus, Alamosaurus, Apatosaurus, etc.) - Modern bovines and baleen whales
