Comments
The right humerus of a subadult hadrosaur. The morphology matches that of saurolophinae. Members of Brachylophosaurini seem to match most closely. Brachylophosaurus canadensis is the closest match.
There is some lateromedial crushing that makes the whole deltopectoral crest look more slender.
