Fig. 6. Maxilla comparison of a size class 2 Edmontosaurus annectens Marsh, 1892 from the late Maastrichtian Hell Creek Formation, Montana, USA (A, LACM 23502, right maxilla in lateral view) and a size class 1 Ugrunaaluk kuukpikensis gen. et sp. nov. from the early Maastrichtian Prince Creek Formation, Alaska (B, UAMES 4327, right maxilla in lateral view). U. kuukpikensis has a relatively low maxilla compared to its length. The height (H) to length (L) ratio is 0.32 whereas that of size class 2 E. annectens is 0.41.
