Fossils of Alaska

Nanuqsaurus (meaning "polar bear lizard") is a genus of tyrannosaurine theropod dinosaur known from the Late Cretaceous (Latest Campanian age) Prince Creek Formation of the North Slope of Alaska. It contains a single species, Nanuqsaurus hoglundi, known from a partial skull and multiple undescribed postcranial and teeth elements.

Alaskacephale is an extinct genus of pachycephalosaurid, a group of dome-headed, herbivorous ornithischian dinosaurs, that lived during the Maastrichtian stage of the Late Cretaceous period in what is now northern Alaska. The genus is one of the few known Arctic dinosaurs and was found in the Prince Creek Formation, which preserves a menagerie of fossils. The only known specimen, a squamosal bone, was found in 1999 and later described in 2005. However, Alaskacephale was not formally named until the next year.
