Yuanyanglong bainian

† Yuanyanglong bainian is an Early Cretaceous omnivorous theropod from the Yixian Formation of China, possibly an oviraptorosaurian. Named for the centennial of the Paleontological Society of China, it contributes to the ornate diversity of the Jehol feathered fauna.

Diet & Feeding

Omnivore

Yuanyanglong bainian had a varied diet that included both plants and animals. Omnivorous dinosaurs were versatile feeders, able to exploit multiple food sources, which gave them an advantage in changing environments.

Time Period

Cretaceous Early Mesozoic Era

Yuanyanglong bainian 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.
