Sinotyrannus kazuoensis

† Sinotyrannus kazuoensis is a large Early Cretaceous tyrannosauroid from Liaoning Province, China. At several meters in length, it was among the largest Cretaceous theropods from Asia before the Maastrichtian, challenging assumptions about tyrannosaur size evolution.

Diet & Feeding

Carnivore

Sinotyrannus kazuoensis 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

Sinotyrannus kazuoensis 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.
