Fig. 10. Dentary comparison of size class 2 Ugrunaaluk kuukpikensis gen. et sp. nov. (A, UAMES 4946, left; C, UAMES 12941, right) from the late Maastrichtian Prince Creek Formation, Alaska, dentary in lateral view; and size class 2 Edmontosaurus annectens Marsh, 1892 (B, BHI-6218, cast, reversed) from the late Maastrichtian Hell Creek Formation, South Dakota, USA, right dentary in lateral view. Note that U. kuukpikensis has a shorter edentulous process than E. annectens. C. Right dentary of U. kuukpikensis showing how the proximal edentulous process length and dental battery length are defined. D. Dentary regression analyses. Biplot of posterior symphyseal process length versus dental battery length. U. kuukpikensis has a shorter symphyseal process than in E. annectens. When the regressions show statistically indistinguishable slope values but statistically significant differences in elevation, P values are marked with an asterisk. Because the lines for E. regalis and U. kuukpikensis are statistically ... : Published as part of Mori, Hirotsugu, Druckenmiller, Patrick S. & Erickson, Gregory M., 2016, A new Arctic hadrosaurid from the Prince Creek Formation (lower Maastrichtian) of northern Alaska, pp. 15-32 in Acta Palaeontologica Polonica 61 (1) on page 25, DOI: 10.4202/app.00152.2015, http://zenodo.org/record/13263701 ...
