Nothronychus (name meaning "slothful claw") is a genus of therizinosaurid theropod dinosaur that lived in North America during the Late Cretaceous period.
Nothronychus had long, razor-sharp claws on each of its hands, which it used for foraging and defending itself from predators. It had a pot belly, which was used to help it digest ingested plant matter.
Two Nothronychus from the Zuni-Basin are striping leaves off of trees when they are attacked by a pack of hungry Suskityrannus. However, they successfully fend off the small tyrannosaurs, who then give up in favor of cannibalizing one of their fallen pack mates. However, it is revealed that the water by the lake and the fallen Suskityrannus were contaminated by a toxic microorganism that will kill anything that ingests it and the rest of the pack dies. The Nothronychus are relatively safe, as they are herbivores, unless they drank from the contaminated water, of course.
