The left humerus of a juvenile hadrosaur. Found near Hamilton. The closest formation is Two Medicine formation. The deltopectoral crest seems fairly robust for such a young animal so I'm leaning towards this being Lambeosaurine instead of Saurolophine, which would make it most likely Hypacrosaurus. The shape also fits quite well with a juvenile Hypacrosaurus I have restored some small areas where there were large holes. But I have left the largest area of damage due to it being a little unclear as to how robust or slender that area would have been.

Partial chevron of a hadrosaur. Likely Edmontosaurus.

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.

Left coracoid of a medium sized hadrosaur from the Judith River formation. Both lambeosaurine and saurolophine hadrosaurs are present in the Judith River formation. This coracoid is consistent with the morphology of saurolophine hadrosaurs. The closest match is Brachylophosaurus canadensis.

Has anybody figured out the exact systematic placement of Stephanosaurus marginatus? As far as I can recall, the holotype of S. marginatus (CMN 419) consists of bones of the forelimb and the foot as well as fragments of neck vertebrae, teeth, and ribs (disassociated bones cataloged under CMN 419 [including a theropod ischium] were provisionally referred to T. marginatus by Lambe 1902, but were later referred to Lambeosaurus by Gilmore 1924). The two editions of the Dinosauria list Stephanosaurus and its type species as a nomen dubium (probably based on the assessment of Stephanosaurus as gen.
