Prettige feite

Yumenornis lived about 121 to 113 million years ago, during the early Cretaceous period.2

The only known fossil of Yumenornis includes a partial breastbone, shoulder bones, and a complete right wing.1

Yumenornis was a relative of Gansus, another ancient bird from the same area in China.1

Scientists think Yumenornis was larger than its relative Gansus, based on its thicker upper arm bone.1

Yumenornis had a sharp, pointy breastbone shaped like a 90-degree angle, unlike the wider breastbone of Gansus.1

The tip of the Yumenornis wing was longer than its upper arm, giving it a long hand section.1

KI-prent van Yumenornis — 'n KI-prent van hoe Yumenornis 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.

Vir dino-kenners

Wetenskaplike naam: Yumenornis
Benoem deur: Wang et al. 20133
Groep: Vroeë voëls
Familie / klade: Ornithuromorpha3
Klassifikasie: Theropoda > Avialae3
Ouderdom van die rotse: 121 tot 113 miljoen jaar (Aptian)3
Rotsformasies: Xiagou3
Lande: China3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Yumenornis was named by Wang and colleagues in 2013 based on a fossil found in the Changma Basin of Gansu Province, China. The name honors Yumen City near the discovery site and Mr. Zhao-Chu Huang.1
Steeds omstrede: Because the only fossil lacks the legs and feet, scientists are not sure whether Yumenornis lived in trees, on the ground, or near water.1
