CT-based reconstruction corroborates direct osteological observation. CT renderings of the skull roofs of two Euoplocephalus specimens, AMNH 5405 (A,C) and UALVP 31 (B,D). A and B show in dark grey the portion of the skull represented in C and D in relation to the entire skull, in oblique right anterior view. C and D are sliced to mimic the areas preserved in UALVP 47977, and show internal features of the skull in ventral view that correspond to those of UALVP 47977 (Fig. 2), with anterior towards the bottom of the page. oo, ocular osteoderm; pp, paroccipital process; q, quadrate. For other abbreviations, see Figs 1 and 2.
