Yongjinglong

Naam beteken: “dragon of Yongjing (the county in Gansu, China)”1

Yongjinglong was a big, long-necked plant-eater that lived in what is now China. It had a very long shoulder blade that stretched more than half the length of its body. Scientists think it was still growing when it died.1

Prettige feite

Yongjinglong's shoulder blade was extremely long and straight, stretching over half the length of its trunk.1

Its neck and back bones had deep, air-filled holes called pleurocoels that covered the whole side of each bone, making the skeleton lighter.1

The ridges on the sides of its middle back bones formed a pattern that looks like the Roman numeral XI.1

Yongjinglong lived about 125 to 113 million years ago, during the Early Cretaceous period.2

The only known fossil is a subadult, meaning Yongjinglong was not fully grown when it died.1

Its teeth were long and spoon-shaped, perfect for scooping up plants.1

KI-prent van Yongjinglong — 'n KI-prent van hoe Yongjinglong 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: Yongjinglong
Benoem deur: Li et al. 20144
Groep: Langnekke
Familie / klade: Euhelopodidae4
Klassifikasie: Sauropodomorpha > Sauropoda > Macronaria4
Ouderdom van die rotse: 126 tot 113 miljoen jaar (Barremian / Aptian)4
Rotsformasies: 54
Lande: China4
Fossielrekords: 1 in The Paleobiology Database4
Ontdekking: Yongjinglong was discovered in 2008 by Li Daqing and You Hailu beside the G75 Highway in Gansu, China. It was named and described by Li and colleagues in 2014.1 2
Steeds omstrede: Scientists are not sure exactly how big Yongjinglong grew, because the only known fossil is from a young animal.1
