Dzina limatanthauza: “Nakona swimmer”1

Ankadya: NyamaMaplesiosauriKumapeto kwa KretaseKwenikweni si dainoso

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

Mfundo zosangalatsa

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

Chithunzi cha Nakonanectes chopangidwa ndi AI — Chithunzi cha momwe Nakonanectes mwina ankaonekera, chopangidwa ndi kompyuta kuchokera pa zomwe asayansi amadziwa. Ndi kungoyerekeza: nyama yeniyeniyo mwina inkaoneka mosiyana, ndipo palibe amene akudziwa mitundu yake yeniyeni.

Mfundo iliyonse patsamba lino ili ndi nambala yosonyeza kumene yachokera. Ngati talakwitsa kanthu, pepa, ndife okonda madino, osati magazini ya sayansi. Tiuze pa [email protected] ndipo tikonza.

Rex ali ndi njala! Dino Wiki ndi ntchito ya bambo kwa mwana wawo wamwamuna wokonda madainoso, yaulere popanda zotsatsa ndi zokazonda. Akuluakulu angadyetse Rex zokhwasula-khwasula kuti tsambali lipitirize kupezeka pa intaneti.Dyetsa Rex
