Chaoyangia beishanensis

† Chaoyangia beishanensis is an ornithuromorph bird from the Early Cretaceous of Liaoning, China, representing a step toward modern bird body plans. Known from incomplete skeletal material, it possesses a pygostyle and fused clavicles (furcula) characteristic of modern birds. A carnivore feeding on small fish or invertebrates, it inhabited lake margins in the Jehol Biota. Its discovery informed early debates about the radiation of modern-style avian features.

Diet & Feeding

Carnivore

Chaoyangia beishanensis 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

Chaoyangia beishanensis 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.
