Is this the real nose of Doswellia?

The preserved portion of the Doswellia premaxilla is so odd, I wondered if it was incomplete. Maybe the preserved portion is only the palatal portion of the premaxilla. The tiny holes are then best considered sinus openings, rather than nares. If so it might have looked like this. Now, not so odd. The posterior portion of the long premaxillary ascending process may even be present at mid rostrum (the diagonal yellow strip).

Figure 1. Doswellia nose restored to match that of sister taxa. In this restoration, the pmx ascending process is gracile and missing, along with the anterior naris.

Earlier we looked at Doswellia here (updated) and here (not updated).
