Chased by Dinosaurs

Nigel Marven, a naturalist who can travel across time, encounters and interacts with prehistoric life in Land of Giants and The Giant Claw. Marven uses direct observation to answer palaeontological puzzles. He looks for the uncommon dinosaur Therizinosaurus in The Giant Claw. Marven originally believes it to have been a huge carnivore because of its large claws. Marven travels to the Land of Giants to find Argentinosaurus, one of the biggest dinosaurs ever to exist, and watch how the enormous predatory dinosaur Giganotosaurus hunted it.
