Nothronychus was a therizinosaurid theropod dinosaur. (92-83 MYA)
It was once a killer, but metamorphosed to vegetarian. It had razor sharp claws good for stripping plants. It was pot-bellied and bizarre. Nothronychus was related to another animal called Therizinosaurus.
A Nothronycus from the Zuni-Basin is attacked by Zunityrannus. The Zunityrannus stalks off, feeding off a carcass and then going to sleep, never to wake up. Then two Nothronycus are attacked by a pack of hungry Zunityrannus. Unsuccessful, the pack turn cannibal, feeding off the dead Zunityrannus. Then they die. It is revealed that the water by the lake and the carcasses are infected by a disease which will kill anything that eats it. Nothronycus are pretty safe, as they are herbivores, unless they drank from the toxic water, of course.
