formation region during the Edmontonian faunal stage in a climate that was around 10 to 12°C during summer months and -2°C ± 3.9°C during the winter months. Other animals alongside Nanuqsaurus include an unnamed leptoceratopsid, the hadrosaurid Edmontosaurus (similar to E. regalis), an unnamed lambeosaurine, an unnamed thescelosaurine (mentioned to be similar to Parkosaurus and Thescelosaurus), an unnamed orodromine (mentioned to be similar to Orodromeus), the ceratopsid Pachyrhinosaurus perotorum, the pachycephalosaurid Alaskacephale, a large troodontid referred to the dubious genus Troodon, the dromaeosaurid Dromaeosaurus, the dromaeosaurid Richardoestesia (similar to R. isosceles), an unnamed saurornitholestine, an unnamed ornithomimosaur, and multiple avialans. In contrast to the contemporary large herbivores Edmontosaurus and Pachyrhinosaurus, which apparently preferred coastal lowland and upland environments respectively, Nanuqsaurus'' appears to have been fairly ubiquitous throughout the Prince Creek landscape.
