 | This dinosaur restoration is inaccurate, or its accuracy is disputed. Reason: The epiparietal spikes were oriented incorrectly in the original description, which this restoration follows. |
| 描述 |
Pachyrhinosaurus perotorum skulls and integument reconstruction through ontogeny. Hypothesis of craniofacial changes in osteology and integument through some of the ontogenetic stages of Pachyrhinosaurus perotorum listed in Table 2. Stage 2 skull based on juvenile P. lakustai of Currie et al.. Stage 4 skull based on DMNH 21460. Stage 6 skull based on DMNH 22558. Right-side ‘life’ reconstructions based on hypotheses of Pachyrhinosaurus integument structures of Hieronymus et al. [10], and new data from DMNH 21460. Light tan indicates ‘normal’ skin, while dark brown indicates cornified scales, horns, sheaths, or other cornified tissue. Scale bar equals 50 cm. |
