Nothronychus looking at the Raptor
Nothronychus was a therizinosaurid theropod dinosaur that lived from 92 to 83 million years ago. It was once a killer, but metamorphosed to vegetarian. It had razor sharp claws good for stripping plants and defending itself. It was pot-bellied and bizarre. Nothronysuchus was related to another animal called Therizinosaurus.
In When Dinosaurs Roamed America
In the Middle Cretaceous segment, a raptor ran away from a pack and he ran into a Nothronychus and was wary, as he had never seen one before. The raptor saw it is possbly prey so he attacked, but he got hit by the Nothronychus's claws. Raptors rarely makes mistakes, but Nothronychus is rare in America. The raptor ran away to let the odd dinosaur feed on the trees. Later, when the Zuniceratops were fighting, the Nothronychus heard them and he quickly got back to eating. Late, during the fire, he is running away. Lastly, the narrator says that the young of Nothronychus will get weirder and weirder over the course of evolution.
