The Prince Creek Formation is a geological formation in Alaska with strata from the early Maastrichtian stage of the Upper Cretaceous, dating to between 70 and 69 million years ago.[1] Dinosaur remains are among the fossils that have been recovered from the formation.[2]

Vertebrate paleofauna

Theropods

Indeterminate tyrannosaurid remains present, mostly in the form of teeth. [3]
