Sauronitholestes was another raptor from Alberta, Montana, and New Mexico. It is known from quite a few well preserved specimens from these locations, specifically Dinosaur Park Formation, Dinosaur Provincial Park, Oldman Formation, and Two Medicine Formation. It lived from the Campanian to the Maastrichtian ages of the Late Cretaceous, about 77 to 69 million years ago. It was about 1.8 meters long and would have been 0.6 meters tall, weighing in at 10 kilograms. It lived in a plains-like habitat and floodplain swamps, and was the most common small theropod in its region, its teeth found much more often than its contemporary Dromaeosaurus. Its teeth have been found embedded in a pterosaur wing, though the large size of the pterosaur indicates that the Sauronitholestes was just scavenging. It was fed on by the large tyrannosaurs of the region - Gorgosaurus and Daspletosaurus
