Are you (Thomas R. Lipka) hypothesizing that nakedness was a primitive
condition for nodosaurs?  Or that _Priconodon_ had lost the body armor of its
ancestors?  If the former, I would have to say that the presence of body
armor in polacanthids, ankylosaurs, stegosaurs, scelidosaurs, scutellosaurs,
and all other nodosaurids makes it most unlikely that nodosaurs were
primitively unarmored.
