How did *Xiongguanlong*'s estimated mass compare to the *T. rex* specimen SUE?
Answer
It was significantly lighter, appearing almost like a flyweight.
*Xiongguanlong* is classified as a mid-sized carnivore, with an estimated body mass between 270 and 300 kilograms (600 to 660 pounds). In stark contrast, the famously massive *Tyrannosaurus rex* specimen known as SUE weighed in the range of six to seven tons. When comparing these figures, the massive disparity in size means that *Xiongguanlong* would appear extremely light, described comparatively as almost a flyweight when set against the colossal dimensions of a mature *T. rex*.
