Qianxisaurus

Naam beteken: “lizard from western Guizhou”1

Het geëet: VleisSeereptieleMiddel-TriasTegnies nie 'n dinosourus nie

Qianxisaurus was a marine reptile that swam in the warm seas of China about 238 million years ago. It had a long body, a long tail, and a snout longer than the rest of its skull. This creature was not a dinosaur, but a type of eosauropterygian, a group of ancient sea reptiles.1

Prettige feit: hierdie seereptiel het geswem terwyl dinosourusse op land geloop het. Almal noem hulle dino's, maar hulle was 'n ander tak van die reptiele.

Prettige feite

Qianxisaurus had 28 back vertebrae and four sacral vertebrae, which is unusual for early sauropterygians.1

Its skull was only 7.6 cm (3 inches) long, but the whole animal was over 80 cm (2 feet 7 inches) in length.1

The name Qianxisaurus comes from 'Qianxi', meaning western Guizhou in Chinese, and 'saurus' meaning lizard.1

Qianxisaurus had a very small supratemporal fenestra, a hole in the skull roof, which was only slightly larger than a foramen in the parietal bone.1

Its dorsal ribs had a longitudinal groove on the upper-back surface, a feature shared with some other early marine reptiles like Corosaurus and Sanchiaosaurus.1

The only known fossil of Qianxisaurus was discovered in 2006 near the Huangnihe River in Xingyi, Guizhou, and is now kept at the National Museum of Natural Science in Taiwan.1

KI-prent van Qianxisaurus — 'n KI-prent van hoe Qianxisaurus 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: Qianxisaurus
Benoem deur: Cheng et al. 20122
Groep: Seereptiele
Familie / klade: Eosauropterygia2
Klassifikasie: Sauropterygia2
Ouderdom van die rotse: 241 tot 237 miljoen jaar (Ladinian)2
Rotsformasies: Falang2
Lande: China2
Fossielrekords: 1 in The Paleobiology Database2
Ontdekking: Qianxisaurus was named by Yen-Nien Cheng, Xiao-Chun Wu, Tamaki Sato and Hsi-Yin Shan in 2012 based on a nearly complete skeleton found in the Zhuganpo Member of the Falang Formation in Guizhou, China.1
Steeds omstrede: Scientists are not sure whether Qianxisaurus was a pachypleurosaur or a more basal eosauropterygian, and its exact relationships within the group are still debated.1
