Zhongjianornis
Zhongjianornis was a pigeon-sized bird that lived in China during the Early Cretaceous, about 120 million years ago. It had a toothless beak and strong wing muscles, making it a good flier. This little bird helps scientists understand how early birds evolved and lost their teeth.12

Anndal belɗungal
Zhongjianornis is one of the most primitive birds known to have completely lost its teeth, developing a beak instead.2
Its humerus had a large, robust deltopectoral crest, which was as wide as the bone shaft and more than one-third the total length of the humerus, indicating strong flight muscles.3
The only known fossil of Zhongjianornis is a nearly complete skeleton with some poorly preserved feather imprints.3
Zhongjianornis lived during the Aptian age of the Early Cretaceous, about 121 to 113 million years ago.3
Scientists initially thought Zhongjianornis was very primitive, but later research in 2012 suggested it was more similar to advanced euornithean birds like Chaoyangia.1
The species name yangi honors Yang Zhongjian, the founder of the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing.1

Feññinoowo goonga
Fenaande: Zhongjianornis was the most primitive toothless bird.
Goonga: While initially thought to be very primitive, later analysis in 2012 showed that Zhongjianornis is more closely related to advanced euornithean birds, not the most primitive.1
