The Giant Claw.Nigel searches the early Mongolia deserts and forests for Therizinosaurus (10 m, 5 t), who has massive and very long claws. Nigel's tent is immediately trampled by a Saurolophus (10 m), but he still goes off for his adventure. On his journey, Nigel dashes across a nesting ground of Protoceratops (3 m), and deflects them from attacking him by using a red flag. He enters a forest ruled by Velociraptor (2 m), and finds a pack of them bringing down a large male Protoceratops. In the night, Nigel catches a scorpion and explains that they have been on the planet long before the dinosaurs, and are still alive today. He also finds a group of Mononykus (1 m) and discovers they have feathers. The next morning he finds that the Mononykus have eaten his scorpion, and heads out of the denser parts of the forest. There he finds the nesting site of a Therizinosaurus, along with the embryo of one, but also finds herbivore dung around the area. Nigel cannot understand why it is scattered around the nest of Therizinosaurus which he thinks must be a predator...
