Keilhauia

Igama lisho ukuthi: “Isilwane sika-Keilhau”1

Udla: InyamaAma-ichthyosaurEarly CretaceousAkuyona i-dinosaur ngempela

I-Keilhauia kwakuyisilwane sasolwandle esifana nedolphin esasiyiphila ngesikhathi se-Early Cretaceous, eminyakeni eyizigidi ezingu-145 edlule. Yayinamehlo amakhulu nomlomo omude, futhi yayibhukuda ezilwandle ezingashoni eduze nalapho kukhona i-Norway namuhla. Yayinde njengemoto encane!1

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

Amaqiniso amnandi

I-Keilhauia yaziwa ngamathambo owodwa kuphela, atholakala ngonyaka ka-2010 esiqhingini sase-Spitsbergen.1

Igama layo elithi nui, livela ezinhlamvini zenhlangano yentsha yase-Norway ebhekene nemvelo ebizwa ngokuthi i-Natur og Ungdom.1

Yayinezingxenye ezibanzi phezulu ethanjeni le-hip (ilium) kanye nethambo elincane le-ischiopubis uma liqhathaniswa nethambo lethanga, okusiza ososayensi ukuba bayihlukanise nezinye izilwane ezibizwa ngama-ichthyosaur.1

I-Keilhauia iyisilwane esibizwa nge-ichthyosaur esiphelele kunazo zonke ezaziwayo kusukela esikhathini se-Berriasian, ekuqaleni kwe-Cretaceous Period.1

Amathambo ayo e-pelvic girdle yiwona aphelele kunawoke atholakala kusukela e-Cretaceous Period.2

Yayiphila olwandle olungashoni olwalunomgogodla ongenamoya omncane, lapho izindawo ezibandayo zazisekela izilwane eziningi ezingenamgogodla ezifana nama-ammonite nama-brachiopod.1

Isithombe sika-Keilhauia 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: Keilhauia
Iqanjwe ngu: Delsett et al. 20173
Iqembu: Ama-ichthyosaur
Umndeni / i-clade: Ophthalmosauridae3
Ukuhlukaniswa: Ichthyosauria > Ichthyosauromorpha3
Inkathi yamadwala: 143 kuya ku-137 wezigidi zeminyaka (Berriasian)3
Izakhiwo zamatshe: Agardhfjellet3
Amazwe: Svalbard3
Izinsalela ezitholiwe: 1 ku-Paleobiology Database3
Ukutholakala: Amathambo okuqala e-Keilhauia atholakala ngonyaka ka-2010 yi-Spitsbergen Mesozoic Research Group e-Svalbard, e-Norway. Ososayensi bayiqamba ngonyaka ka-2017 ngemva kwesazi sokuma komhlaba sase-Norway u-Baltazar Mathias Keilhau.1
Kusaphikiswana ngakho: Ososayensi abaqiniseki ngokuthi i-Keilhauia ihlobene kanjani nezinye izilwane ezibizwa ngama-ichthyosaur ngoba ukhakhayi lwayo alulondolozekanga kahle, ngakho indawo yayo emndenini ayiqinisekile.1
