Nakonanectes

Igama lisho ukuthi: “Umubhukudi wase-Nakona”1

Udla: InyamaAma-PlesiosaurLate CretaceousAkuyona i-dinosaur ngempela

I-Nakonanectes yayiyisilwane esihuquzelayo sasolwandle, esaphila olwandle, hhayi isilwane esihuquzelayo esifana nedayinoso. Yayinentamo emfushane kunezihlobo zayo eziningi, okuyenza ibe uhlobo olukhethekile lwe-elasmosaurid.1 2

Iqiniso elimnandi: lesi silwane sasolwandle sasibhukuda ngenkathi ama-dinosaur ehamba emhlabathini. Wonke umuntu ubabiza ngama-dino, kodwa ayeyigatsha elihlukile lezilwane ezihuquzelayo.

izinto ezinhle

Amaqiniso amnandi

I-Nakonanectes yayinamathambo entamo angu-39 kuya kwangu-42 kuphela, kuyilapho ezinye izilwane eziningi zohlobo lwe-elasmosaurid zazinamathambo angaphezu kwangu-70.1 2

Kwakungenye yezilwane ezincane kunazo zonke zohlobo lwe-elasmosaurid ezake zatholakala, inobude obungamamitha angu-5.1 kuya kwangu-5.6.1 2

Izinsalela zatholakala ngonyaka ka-2010 ngumzingeli okuthiwa u-David Bradt esigodini sase-Montana.1

I-Nakonanectes yaphila eminyakeni eyizigidi ezingu-72 kuya kwezingu-66 edlule, ekupheleni kweNkathi yamaDayinoso.3

Ugebhezi lwayo lwatholakala lucishe luphelele, okuyinto engavamile ezinsaleleni zohlobo lwe-elasmosaurid.1 2

Izilwane zohlobo lwe-elasmosaurid ezinentamo emfushane ezifana ne-Nakonanectes zavela ezikhokhweni ezinentamo ende ezingxenyeni ezahlukene zomhlaba.1 2

Isithombe sika-Nakonanectes esenziwe nge-AI sokuthi kungenzeka ukuthi wayebukeka kanjani, senziwe yikhompyutha ngokusekelwe kulokho okwaziwa ososayensi. Lokhu kuwukuqagela: isilwane sangempela kungenzeka ukuthi sasibukeka ngokuhlukile, futhi akekho owazi imibala yaso yangempela.

Ukutholakala: I-Nakonanectes yaqanjwa ngonyaka ka-2017 ngu-Danielle Serratos, Patrick Druckenmiller, kanye no-Roger Benson. Izinsalela zatholakala ngonyaka ka-2010 ngumzingeli u-David Bradt ku-Bearpaw Shale yase-Montana, e-USA.1 3
Kusaphikiswana ngakho: Ososayensi basaxoxa ngokuthi i-Nakonanectes ingena eqenjini le-Styxosaurinae noma le-Elasmosaurinae.3

Yonke imininingwane ekuleli khasi inenombolo ekhomba umthombo wayo. Uma kukhona esikwenze kabi, siyaxolisa, singabalandeli bama-dino, hhayi iphephabhuku lesayensi. Sitshele ku-[email protected] futhi sizokulungisa.
