Pengornis is the largest known enantiornithine bird from the Early Cretaceous of northeast China.1

Its skull is one of the best preserved among all Mesozoic birds, showing details like tiny teeth and wear facets.2

Pengornis had a globose humeral head that stuck out further than its deltopectoral crest, a feature not seen in other enantiornithines.2

The name comes from 'Peng', a giant mythological bird in Chinese folklore, and 'ornis' meaning bird in Greek.1

Its teeth were small, conical, and not curved, similar to those of the early bird Archaeopteryx.2

Pengornis had a long tail with a pygostyle, a fused bone at the tip that helped control flight.2

發現: Pengornis was named in 2008 by Zhou, Clarke, and Zhang based on a nearly complete skeleton found in the Jiufotang Formation in Liaoning, China. The species name 'houi' honors the pioneering paleo-ornithologist Lianhai Hou.1 2
仍有爭議: Scientists debate whether Enantiornithes and Ornithurae (the group including modern birds) are truly separate groups. Pengornis has features of both, which blurs the line.1 2
