Vescornis

Naam beteken: “evening bird”1

Vescornis was a tiny, feathered dinosaur that could fly. It lived during the Early Cretaceous, about 122 million years ago, in what is now China. This little bird had long foot claws and short wing fingers, which made it great at flying but not so good at climbing trees.1 2

Prettige feite

Vescornis had very small wing claws and long, strong foot claws, which helped it fly better but made it worse at climbing than many other early birds.2

The only known fossil of Vescornis was first thought to come from the Yixian Formation, but later geologists realized it was actually from the Huajiying Formation.1

Vescornis might be the same animal as another early bird called Jibeinia, but scientists are not sure because the Jibeinia fossil got lost.1

The name 'Hebeiornis' was given to the same fossil in 1999, but that name is not used because it was not described well enough.1

Vescornis lived about 122 million years ago, during the Early Cretaceous period.1

KI-prent van Vescornis — 'n KI-prent van hoe Vescornis 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 Vescornis was a true bird like modern birds.

Waarheid: Vescornis was an enantiornithine, a group of ancient birds that had teeth and claws, and it is not a direct ancestor of today's birds.1

Vir dino-kenners

Wetenskaplike naam: Vescornis
Benoem deur: Zhang et al. 20044
Groep: Vroeë voëls
Familie / klade: Enantiornithes4
Klassifikasie: Theropoda > Avialae4
Ouderdom van die rotse: 126 tot 120 miljoen jaar (Barremian / Aptian)4
Rotsformasies: Yixian4
Lande: China4
Fossielrekords: 1 in The Paleobiology Database4
Ontdekking: The fossil was found in Hebei Province, China, and was described by Zhang and colleagues in 2004. It is stored at the Nanjing Institute of Geology and Paleontology.1
Steeds omstrede: Scientists still debate whether Vescornis is the same species as Jibeinia, because the Jibeinia fossil is lost and the two look very similar.1
