Sarabosaurus

Igama lisho ukuthi: “intulo yomkhathi wasogwadule”1

Udla: InyamaAma-MosasaurusLate CretaceousAkuyona i-dinosaur ngempela

I-Sarabosaurus yayiyisilwane esincane esihlala emanzini, esifana nentulo, esabe sibhukuda olwandle olufudumele olwalumboze maphakathi neNyakatho Melika. Yaphila eminyakeni eyizigidi ezingu-94 edlule, ngesikhathi sama-dinosaur, futhi iyisilwane esidala kunazo zonke esifana ne-mosasaur esake satholakala kuleso sifunda.1 2

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

Amaqiniso amnandi

I-Sarabosaurus iyisilwane esidala kunazo zonke esifana ne-mosasaur esaziwayo esivela e-Western Interior Seaway, esiphila eminyakeni eyizigidi ezingu-93.7 edlule.1

Isilwane esisodwa kuphela esaziwayo esasingumuntu omdala, esasineminyaka emi-3 kuya kwemi-4 kuphela lapho sifa.1

Igama layo livela egameni lesi-Arabhu elithi 'sarab' elisho umkhathi wasogwadule, ngoba ulwandle eyayihlala kulo seluphele kudala.1

I-Sarabosaurus yayinendlela ehlukile yokuhambisa igazi ebuchosheni bayo, ehlukile kwezinye izintulo, efana nendlela imikhomo eyavela ngayo.2

Igama lohlobo elithi 'dahli' lihlonipha u-Steve Dahl, umvolontiya owasiza ukuqoqa izinsalela kuleyo ndawo.1

Ososayensi basebenzise i-micro-CT scanning ukufunda ugebhezi nokwenza imephu yemithambo yegazi ye-Sarabosaurus.2

I-Sarabosaurus yayicishe ibe ngamamitha angu-3 (amafidi angu-9.8) ubude, incane uma iqhathaniswa nama-mosasaur amakhulu kakhulu eza kamuva.1

Isithombe sika-Sarabosaurus 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: Sarabosaurus
Iqanjwe ngu: Polcyn et al. 20233
Iqembu: Ama-Mosasaurus
Umndeni / i-clade: Mosasauridae3
Ukuhlukaniswa: Mosasauroidea3
Inkathi yamadwala: 94 kuya ku-90 wezigidi zeminyaka (Turonian)3

Ukutholakala: Insali yatholakala ngoNdasa 2012 ngumvolontiya u-Scott Richardson emhlabathini oyi-shale ompunga wase-Utah. Yaqanjwa ngo-2023 ngu-Michael Polcyn nozakwabo, kanti uhlobo lwayo lwathola igama lomvolontiya u-Steve Dahl.1 2
Kusaphikiswana ngakho: Ososayensi basaphikisana ngokuthi i-Sarabosaurus ihlobene kanjani ngqo nezinye izilwane zakuqala ezifana ne-mosasaur, ikakhulukazi indawo yayo emndenini wazo.1
