Any skull restoration is extremely tentative, so I'm holding off on any kind of restoration. There are important points, though: <i>Xiongguanlong</i> lacks any kind of cranial decoration. It lacks the crests of <i>Guanlong</i> and <i>Proceratosaurus</i> or the ruggosities of later "true" tyrannosaurs. Even though the paper compares its snout length to <i>Alioramus</i>, it also lacks the nasal bumps of that taxon. Waitasecond, I think I read awhile back that <i>Alioramus</i> might be a juvenile <i>Tarbosaurus</i>... Anyway. It is interesting that <i>Xiongguanlong</i> has such a long, narrow snout. Reminds me of unenlagiine dromaeosaurs, honestly, but with bigger teeth. I’m disappointed that the skull is so horribly crushed, and the skull sutures are poorly preserved.
