How is Xiongguanlong's physical dimension described relative to its famous descendants?

Answer

Medium-sized for a carnivore

The text describes Xiongguanlong as decidedly medium-sized for a carnivore, noting its length of about 4.3 meters in contrast to later, famous tyrannosaurs that exceeded 12 meters in length. This relative scale is highlighted as perhaps the most significant determinant of its diet and ecological role. Being medium-sized meant it occupied a niche below the apex predators, managing resources that the truly gigantic theropods had not yet evolved or dispersed to exploit in that region.
