Chubutinectes was a long-necked marine reptile that swam in warm, shallow seas near what is now Argentina. It was not a dinosaur, but a plesiosaur, a type of ocean predator with flippers like a sea turtle.2 1

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

izinto ezimnandi

Iinyani ezimnandi

Chubutinectes lived about 67 million years ago, near the very end of the Age of Dinosaurs.1

It is one of the few plesiosaurs from the Southern Hemisphere whose skeleton after the head is well known.1

Its bones were found in the La Colonia Formation, which was once a warm, shallow sea with limited water flow.1

Scientists used tiny fossils called microfossils to figure out how old the rocks were where Chubutinectes was found.1

Chubutinectes had a special bone in its shoulder called a coracoid with a heart-shaped hole, which helped scientists tell it apart from other plesiosaurs.1

Its arm bone, the humerus, had a back part that ended in an extra bump, a unique feature.1

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

Kwiingcali zeedayinaso

Igama lenzululwazi: Chubutinectes
Inikwe igama ngu:: O'Gorman et al. 20232
Iqela: Iiplesiosauri
Usapho / iclade: Elasmosauridae2
Ukuhlelwa: Plesiosauria > Elasmosauridae > Sauropterygia2
Ubudala bamatye: 72 ukuya ku-66 izigidi zeminyaka (Maastrichtian)2
Izakhiwo zamatye: La Colonia2
Amazwe: i-Argentina2
Iirekhodi zeefosili: 1 kwi-Paleobiology Database2
Ukufunyanwa: Chubutinectes was named in 2023 by paleontologist Jose Patricio O'Gorman and his team. The only known skeleton was collected from the La Colonia Formation in Chubut Province, Argentina.2 1
Kusaxoxwa ngayo: Scientists are still debating exactly how Chubutinectes is related to other plesiosaurs, especially the Weddellonectia group.1
