Xiongguanlong baimoensis

† Xiongguanlong baimoensis is an Early Cretaceous tyrannosauroid from the Xinminpu Formation of Gansu Province, China. This medium-sized precursor to later giant tyrannosaurs is key to understanding the evolutionary transition leading to Tyrannosaurus rex.

Diet & Feeding

Carnivore

Xiongguanlong baimoensis was a meat-eating predator. Carnivorous dinosaurs were active hunters or scavengers, equipped with sharp teeth and claws for catching and consuming prey. They occupied the top of the food chain in their ecosystems.

Time Period

Cretaceous Early Mesozoic Era

Xiongguanlong baimoensis lived during the Cretaceous Early period of the Mesozoic Era, approximately 145,0 to 100,5 million years ago.

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
