Suskityrannus (coyote tyrant) is a tyrannosauroid theropod dinosaur from Late Cretaceous of New Mexico, reaching a possible size of 4-5 meters long and it weighed about 1 ton as an adult, as two of the Suskityrannus' specimens are only known from juveniles.

A lone Suskityrannus was first seen drinking from a lake. It then came across a Nothronychus, and attempted to attack the herbivore, however the therizinosaur swiped the tyrannosaur in the face and successfully warded it off. The Suskityrannus then turned its attention to carrion. The carcass contained a deadly virus , the pathogenic bacteria Clostridium botulinum, which killed the dinosaur. The Nothronychus then returned to eating. Later, a larger pack of Suskityrannus appeared and walked past its dead member. They then started hunting a pair of Nothronychus, however using their enormous claws the therizinosaurs were able to defend themselves. Despite this, one Suskityrannus' managed to bite one of the herbivores' necks. The pack then backed down and began to cannibalize on the dead tyrannosaur, not being aware that it also contained the deadly pathogen. The theropods then contracted the virus and died as well, as was later seen when a Nothronychus walked past and saw their rotting. bodies near the lake.
- In the subtitles of 'The Great Survivors' the tyrannosaur is inaccurately referred to as Sinotyrannus, which was a large tyrannosaur from the Cretaceous of China, over 28 million years earlier than Suskityrannus.
- It was once called by an informal name, "Zunityrannus", which refers to the Zuni Basin in New Mexico, where fossils of the animal have been found. The remains of the animal have not been given an official name or classification by paleontologists until 2019, which gives its official name.
