Nichollsia

Igama lisho ukuthi: “isibankwa sika-Nicholls, esiqanjwe ngemva kwesazi sezinto zakudala u-Betsy Nicholls”1

Udla: InyamaAma-PlesiosaurEarly CretaceousAkuyona i-dinosaur ngempela

I-Nichollssaura yayiyisilwane esihuquzelayo sasolwandle esincane nesishumayo esayiphila olwandle olwalumboze i-Alberta, eCanada. Kwakuyisilwane i-plesiosaur, hhayi i-dinosaur, futhi yayinentamo ende namaphiko amane okubhukuda emanzini. Lesi silwane sisiza ososayensi ukugcwalisa igebe elikhulu leminyaka eyizigidi ezingu-40 emlandweni wamathambo e-plesiosaur eNyakatho Melika.1

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

Amaqiniso amnandi

Amathambo atholakala ngengozi ngabasebenzi ababeshayela imishini emayini yamafutha. Umshini wanquma amanye amathambo, kodwa lonke uhlaka lwamathambo lwalucishe luphelele.1

Le plesiosaur yaqanjwa ngemva kuka-Dkt. Betsy Nicholls, isazi sezinto zakudala esidumile. Igama lokuqala elithi Nichollsia lase lisetshenziselwa uhlobo lwe-isopod, ngakho ososayensi balishintsha laba yi-Nichollssaura.1

I-Nichollssaura yayinamatshe esisu angu-165 (gastroliths) ngaphakathi kwayo. Amatshe ayebushelelezi futhi eyindilinga, mhlawumbe agwinywa ukuze asize ukugaya ukudla.1

Amatshe esisu avela emadwaleni ayeminyaka eyizigidi ezingu-8 kuya kweziy-10 edala kune-plesiosaur uqobo lwayo. Lokhu kusikisela ukuthi i-Nichollssaura kungenzeka ukuthi yabhukuda yaya entshonalanga ukuze iqoqe amatshe ezindaweni zasolwandle zasendulo.1

Yaphila eminyakeni eyizigidi ezingu-110 edlule e-Boreal Sea, ulwandle olufudumele olwalumboze izingxenye zaseNyakatho Melika.1

Uhlaka lwamathambo oluyisibonelo lubukiswa e-Royal Tyrrell Museum e-Alberta, eCanada.1

Isithombe sika-Nichollsia 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.

Ochwepheshe bama-dino

Igama lesayensi: Nichollsia
Iqanjwe ngu: Druckenmiller and Russell 20082
Iqembu: Ama-Plesiosaur
Umndeni / i-clade: Leptocleididae2
Ukuhlukaniswa: Plesiosauria > Sauropterygia2
Inkathi yamadwala: 113 kuya ku-100 wezigidi zeminyaka (Albian)2
Izinsalela ezitholiwe: 1 ku-Paleobiology Database2
Ukutholakala: Isilwane satholakala ngo-1994 ngabasebenzi ababeshayela imishini u-Greg Fisher no-Lorne Cundal emayini yamafutha e-Syncrude e-Alberta. Saqanjwa ngokuthi i-Nichollsia borealis ngu-Druckenmiller no-Russell ngo-2008, kodwa igama lashintshwa laba yi-Nichollssaura ngo-2009 ngoba igama elithi Nichollsia lase lisetshenzisiwe.1 2
