During which geological period did Xiongguanlong baimoensis live?
Answer
Early Cretaceous period
Xiongguanlong baimoensis existed during the Early Cretaceous period. This temporal placement is vital for understanding its evolutionary status, as it predates the massive apex predators associated with the later stages of the tyrannosaur lineage. Its existence in the Early Cretaceous situates it within an ecosystem where the overall predatory dynamics were structured differently, emphasizing smaller and faster hunters before the era of giants fully commenced.
