Dalingheornis

Naam beteken: “Dalinghe bird, named after the Dalinghe River in China”1

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

Prettige feite

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

KI-prent van Dalingheornis — 'n KI-prent van hoe Dalingheornis dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

Mite-breker

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

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

Vir dino-kenners

Wetenskaplike naam: Dalingheornis
Benoem deur: Zhang et al. 20063
Groep: Vroeë voëls
Familie / klade: Euenantiornithes3
Klassifikasie: Theropoda > Avialae3
Ouderdom van die rotse: 126 tot 120 miljoen jaar (Barremian / Aptian)3
Rotsformasies: Yixian3
Lande: China3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: 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
Steeds omstrede: 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
