Kwangsisaurus

Naam beteken: “Guangxi lizard”1

Het geëet: VisSeereptieleVroeë Trias tot Middel-TriasTegnies nie 'n dinosourus nie

Kwangsisaurus was a marine reptile that swam in the warm seas of China during the Middle Triassic. It was a type of sauropterygian, a group that includes the famous plesiosaurs. This reptile had a long body and paddle-like limbs for swimming.1 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

Kwangsisaurus was named by Chinese paleontologist Yang Zhongjian (also known as C. C. Young) in 1959.1

The only known fossil of Kwangsisaurus is a partial skeleton found in Wuming County, Guangxi, China.2

Kwangsisaurus lived during the Olenekian to Anisian stages of the Triassic, about 250 to 244 million years ago.1 2

This reptile was a pistosaurid, a group of early sauropterygians that were ancestors of the later plesiosaurs.1

Kwangsisaurus had dorsal vertebrae with long, expanded transverse processes, which helped support its body.1

Its coracoid bone was broad and plate-like, with a rounded inner edge and a bell-shaped outer edge.1

The humerus (upper arm bone) of Kwangsisaurus was curved, and it lacked an entepicondylar foramen, a hole found in some other reptiles.1

KI-prent van Kwangsisaurus — 'n KI-prent van hoe Kwangsisaurus 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: Kwangsisaurus
Benoem deur: Young 19593
Groep: Seereptiele
Familie / klade: Pistosauroidea3
Klassifikasie: Sauropterygia3
Ouderdom van die rotse: 251 tot 247 miljoen jaar ()3
Rotsformasies: Beisi3
Lande: China3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Kwangsisaurus was named by Chinese paleontologist Yang Zhongjian (C. C. Young) in 1959 based on a partial skeleton found in Wuming County, Guangxi, China.1 2
Steeds omstrede: Scientists are unsure about the exact size of Kwangsisaurus because only a partial skeleton has been found.1
