Yixianornis (meaning "Yixian Formation bird"^[1]) is a bird genus from the early Cretaceous period. Its remains have been found in the Jiufotang Formation at Chaoyang (People's Republic of China) dated to the early Aptian age, around 120 million years ago.^[2] Only one species, Yixianornis grabaui, is known at present. The specific name, grabaui, is named after American paleontologist Amadeus William Grabau, who surveyed China in the early 20th century.
