Chased by Dinosaurs S01 E01 The Giant Claw

"A WALKING WITH DINOSAURS SPECIAL."

Nigel searches the deserts and forests of Cretaceous Mongolia for Therizinosaurus, an obscure dinosaur with massive fossil claws, believing it to have been a huge carnivore. Throughout his journey, Marven comes face-to-face with dinosaurs such as Saurolophus, Protoceratops, Mononykus, Velociraptor and Tarbosaurus, a close relative of the famous Tyrannosaurus rex. Once Marven finds live Therizinosaurus he discovers them to have been a bizarre type of giant plant-eating theropod dinosaur.
