Which other longirostrine tyrannosauroid do *Xiongguanlong*'s body proportions resemble?
Answer
*Alioramus*
Although much of *Xiongguanlong*'s tail and leg structure was not fully preserved in the fossil specimen, the analysis of the available limb and vertebral elements suggests that its overall body proportions align closely with those observed in *Alioramus*. *Alioramus* is itself classified as a longirostrine tyrannosauroid, meaning it shared a similar long-snouted body plan. This similarity in general proportions, despite the age difference, reinforces the placement of *Xiongguanlong* within the spectrum of long-snouted forms that preceded the bulkier tyrannosaurids.
