Which two components contributed significantly to the elongated snout length of Xiongguanlong?
Answer
The premaxillae and maxillae
The overall length of the distinctive snout of *Xiongguanlong* was a composite feature resulting from the elongation of several facial bones. Specifically mentioned as contributing to this extension are the premaxillae and the maxillae. While the nasal bones themselves were noted as being exceptionally long and slender, the adjacent maxillae and premaxillae worked in concert to create the extended facial structure that contrasted sharply with the short, deep snouts of later tyrannosaurs. This arrangement highlights an evolutionary investment in length over robust vertical depth in the skull.
