Reconstruction of the outer layer of Daspletosaurus horneri, based on the distribution of texture on the facial bones. The face in tyrannosaurs was covered by an extensive mask of large, flat scales and regions of armor-like skin on the snout, jaws and ornamental horns. The large horn behind the eye was covered by horn, the same material that makes human fingernails.
