= Edomontosaurus CHAPMAN & BRETT-SURMAN, 1990 (sic)
= Ugrunaaluk MORI, DRUCKENMILLER, & ERICKSON, 2016
Etymology: Transliterated from the Alaskan Inupia noun ugrunnaq, referring to a grazing animal with a long set of grinding teeth, and the adjective -aluk, old. literally, "ancient grazer". The name honors the Alakan Native Inupiq culture from the area where the type material was discovered.
