The Land of the Lost's megafauna consists primarily of dinosaurs; species noted included Coelophysis, Tyrannosaurus, Allosaurus, Triceratops, Brontosaurus, Styracosaurus, Ankylosaurus, and Pteranodon. There are also iguanas, wild blue and red pigs, pink and blue chicken-like birds, Ancient fish, guinea pigs, rhinoceroses, large beetles (called "Tula" by Enik), bamboo, and giant varieties of modern berries and vegetables. It is unknown whether they were placed here by the Altrusians or if they came to the Land of the Lost accidentally. Rick suggests that the plants grow unusually large due to the nature of the soil.
