名字的意思： “Dalinghe bird, named after the Dalinghe River in China”1

吃：肉早期鳥類白堊紀早期

Dalingheornis was a tiny bird that lived during the early Cretaceous period, about 122 million years ago. It had special feet that helped it climb trees, making it one of the first birds to live in the trees. Its long tail had 20 bones, just like some meat-eating dinosaurs!1 2

酷東西

趣味知識

Dalingheornis is the first Mesozoic bird known to have heterodactyl feet, which means its toes were arranged for climbing, like a modern woodpecker.1 2

Its tail was unusually long for a bird, with 20 vertebrae, and it had chevron bones like those of dromaeosaurid dinosaurs.1 2

The only known fossil is a juvenile, so scientists think the long tail might have been a baby feature that changed as it grew up.1

Dalingheornis was named after Yang Liwei, the first Chinese astronaut in space.1

It lived in the early Cretaceous period, about 122 million years ago, in what is now Liaoning Province, China.1

迷思破解王

迷思： Some people think Dalingheornis had a reversed second toe claw for climbing.

真相： Scientists are not sure if the claw was really reversed or just moved after the animal died.1

給恐龍專家

學名: Dalingheornis

類群: 早期鳥類
科 / 演化支: Euenantiornithes3
分類: Theropoda > Avialae3
岩石的年代: 126 到 120 百萬年 (Barremian / Aptian)3

化石紀錄: The Paleobiology Database 收錄 1 筆3
發現: Dalingheornis was named in 2006 by Zhang Zihui and colleagues from a single fossil found in the Yixian Formation in China. The fossil is stored in a private collection.1 3
仍有爭議: Some scientists think Dalingheornis might not be a valid name because the only fossil is in a private collection and cannot be studied by everyone.1
