酷東西

趣味知識

Shengjingornis had teeth only in the front of its long beak, unlike many modern birds which have no teeth.1

Its furcula, or wishbone, was Y-shaped with a wide end on the hypocleidium, a feature that helped with flight.1

The sternum, or breastbone, was shaped like a cake and had a low keel that pointed toward the tail.1

Shengjingornis lived around 121 to 113 million years ago during the Aptian age of the Early Cretaceous.2

Its fossils were found in the Jiufotang Formation, which was once a lake environment with sandstones and mudstones.3

Only one specimen of Shengjingornis has been found, and it is kept at the Liaoning Paleontological Museum.3
