Silutitan

Igama lisho ukuthi: “umdondoshiya womgwaqo kasilika”1

Udla: IzitshaloAma-sauropodEarly Cretaceous

I-Silutitan yayiyisilwane esikhulu esidla izitshalo esinentamo ende esaphila endaweni okuyiyo iChina namuhla. Izinsalela zayo zatholakala kanye namathambo amaningi ama-pterosaur, okuhlanganisa amaqanda nezilwane ezisencane. Lesi silwane sasingesinye sezilwane ezinkulu zokuqala ezihlala emhlabeni ezatholakala kuleyo ndawo ekhethekile yezinsalela.1 2

Amaqiniso amnandi

I-Silutitan yaziwa ngamathambo entamo ayisithupha nezimbambo ezithile kuphela. Ososayensi basebenzise lawo mathambo ukuthola ukuthi ubude bomzimba wayo wawungaphezu kwamamitha angu-20.1

Igama layo lisho 'umdondoshiya womgwaqo kasilika' ngoba izinsalela zatholakala eduze komzila wakudala wokuhweba womgwaqo kasilika eChina.1

I-Silutitan yaphila eminyakeni engaba izigidi ezingu-137 kuya kwezingu-132 edlule, ngesikhathi se-Early Cretaceous.3

Amathambo e-Silutitan atholakala ezindaweni ezinetshe lesihlabathi ezansi nechibi, kanye nezinsalela eziningi zama-pterosaur okuhlanganisa amaqanda nezilwane ezisencane (embryos).1 2

I-Silutitan yayiyi-somphospondylan sauropod, iqembu lezilwane ezinentamo ende ezinamathambo anomoya ngaphakathi okwenza zibe lula.1

Izimfuyo zentamo yayo zazinezindawo eziphumileyo nemigqa ekhethekile eyasiza ososayensi ukuba bayihlukanise nezinye izilwane ezinkulu ezinentamo ende.1

Isithombe sika-Silutitan 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.

Igama lesayensi: Silutitan
Iqanjwe ngu: Wang et al. 20213
Iqembu: Ama-sauropod
Umndeni / i-clade: Euhelopodidae3
Ukuhlukaniswa: Sauropodomorpha > Sauropoda > Macronaria3
Inkathi yamadwala: 137 kuya ku-133 wezigidi zeminyaka (Valanginian)3
Izakhiwo zamatshe: Shengjinkou3
Amazwe: I-China3
Izinsalela ezitholiwe: 1 ku-Paleobiology Database3
Ukutholakala: I-Silutitan yaqanjwa ngonyaka ka-2021 yiqembu lososayensi elaliholwa u-Xiaolin Wang. Izinsalela zatholakala esifundeni sase-Hami e-Xinjiang, eChina, kusukela ngonyaka ka-2016.1 3
Kusaphikiswana ngakho: Ososayensi abaqiniseki ukuthi umzimba wonke we-Silutitan wawungamamitha amangaki ubude, ngoba kutholakale amathambo entamo kuphela. Isilinganiso sobude esingaphezu kwamamitha angu-20 sisekelwe ekuqhathaniseni nesilwane esifana naso esibizwa nge-Euhelopus.1
