Diandongosaurus

Igama lithetha: “Diandong lizard, after the Diandong region of Yunnan, China”1

Yayitya: InyamaIzirhubuluzi zaselwandleiTriassic ephakathiNgokwenene ayisiyo dayinaso

Diandongosaurus was a small marine reptile that swam in the warm seas of China during the Triassic Period. It had a long body and sharp teeth for catching fish. It was only about as long as a ruler!1 2

Inyani emnandi: esi sirhubuluzi saselwandle sasiqubha ngelixa iidayinaso zazihamba emhlabeni. Wonke umntu uzibiza ngokuba ziidayinaso, kodwa zazilisebe elahlukileyo lezirhubuluzi.

izinto ezimnandi

Iinyani ezimnandi

Diandongosaurus had a snout that was not pinched, and the part of its skull in front of the eye was longer than the part behind the eye.2

Its skull had a small opening on top (the supratemporal fenestra) that was smaller than its eye socket.2

The bones that form the forehead (frontals) and the top of the skull (parietals) were fused together into single pieces.2

Its collar bone (clavicle) had a forward-pointing projection, which is unusual.2

The toe bones (ungual phalanxes) of its hind feet were extremely flattened from top to bottom, possibly helping it paddle.2

The only known complete skeleton of Diandongosaurus was found in a famous fossil site called the Guanling Formation, which preserves many Triassic sea creatures.1

Umfanekiso owenziwe yi-AI: Diandongosaurus — Umfanekiso owenziwe yi-AI obonisa indlela Diandongosaurus esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Inyaniso ngeentsomi

Intsomi: Some people might think Diandongosaurus was a dinosaur because it lived long ago and had a long tail.

Inyaniso: Diandongosaurus was not a dinosaur. It was a marine reptile called an eosauropterygian, a group that includes ancestors of plesiosaurs.1

Kwiingcali zeedayinaso

Igama lenzululwazi: Diandongosaurus
Inikwe igama ngu:: Shang et al. 20113
Iqela: Izirhubuluzi zaselwandle
Usapho / iclade: Eosauropterygia3
Ukuhlelwa: Sauropterygia3
Ubudala bamatye: 244 ukuya ku-243 izigidi zeminyaka ()3
Izakhiwo zamatye: Guanling3
Amazwe: iTshayina3
Iirekhodi zeefosili: 1 kwi-Paleobiology Database3
Ukufunyanwa: Diandongosaurus was named in 2011 by Chinese paleontologists Qing-Hua Shang, Xiao-Chun Wu, and Chun Li. They described it from a complete, articulated skeleton found in the Guanling Formation of Yunnan Province.1 2
Kusaxoxwa ngayo: Scientists are not sure exactly how Diandongosaurus is related to other marine reptiles. Some studies suggest it might be a close cousin of both nothosaurs and pachypleurosaurs, but its exact place in the family tree is still debated.2
