Trivia

 * 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, as well as endangered and extinct in the wild animals (and other modern animals from previous episodes) found in Townsville Zoo.
 * All dinosaurs and other prehistoric creatures had modern accurate features, such as feathered maniraptors and quadrupedal pterosaurs.
 * 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
 * Armored dinosaurs (Triceratops, Ankylosaurus, Stegosaurus, etc.) and ground sloths (Megalonyx, Eremotherium) - Modern rhinos and walruses
 * Hadrosaurs (Parasaurolophus, Edmontosaurus, Lambeosaurus, etc.) - Modern Cervus species
 * Large pterosaurs (Pteranodon, Quetzalcoatlus, etc.) - Modern seabirds and birds of prey
 * Small pterosaurs (Rhamphorhynchus, Dimorphodon, etc.) - Modern corvids and small Falco species
 * Prehistoric big cats (Saber-tooth cats, Eurasian cave lions, etc.) - Modern Panthera species
 * Mammoths and other prehistoric elephants - Modern elephants
 * Megalania - Modern Varanus species
 * Teratorns (Teratornis, Argentavis) - Modern vultures
