T Inman that bone in your picture looks to me like the humerus. i.e. The front leg. The artists rendition in my opinion has the scapula (what I call the shoulder) a little smaller than rality for the size of the animal. I also believe it is placed to far foreword. However the pictures of the anotomy show the heart directly above the exit of the front leg as it leaves the chest. It also illustrates the length of the spineous ridges of the dorsal (top) of the spinal column. This illustrates the amount of area on the elks upper chest that is not filled with lung tissue. It also shows as krp is noting. Not a much but abdominal organs on the lower chest behind (caudal) to the front leg.
