    • The striking absence of champsosaurs and crocodiles in polar vertebrate assemblages containing dinosaurs could indicate that some stages of the Cretaceous were cooler than the Turonian-Coniacian interval.

    • A turtle is known from the Cenomanian North Slope of Alaska, but no champsosaur material is known from this area. Hadrosaur material was collected from the latest Cretaceous of Bylot Island and Alaska, but no freshwater reptile material was recovered at either locality.
