Nakonanectes

Igama lithetha: “Nakona swimmer”1

Yayitya: InyamaIiplesiosauriiCretaceous yamvaNgokwenene ayisiyo dayinaso

Nakonanectes was a plesiosaur, a marine reptile that lived in the sea, not a dinosaur. It had a shorter neck than most of its relatives, making it a special kind of elasmosaurid.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

Nakonanectes had only 39 to 42 neck bones, while many other elasmosaurids had over 70.1 2

It was one of the smallest adult elasmosaurids ever found, measuring only 5.1 to 5.6 metres long.1 2

The fossil was discovered in 2010 by a hunter named David Bradt in a canyon in Montana.1

Nakonanectes lived about 72 to 66 million years ago, at the end of the Age of Dinosaurs.3

Its skull was found nearly complete, which is rare for elasmosaurid fossils.1 2

Short-necked elasmosaurids like Nakonanectes evolved from long-necked ancestors in different parts of the world.1 2

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