Plesiopharos

Igama lisho ukuthi: “eduze nesibani sasolwandle, kubhekiselwa esibanini sasolwandle esiseduze nalapho yatholwa khona”1

Udla: InyamaAma-PlesiosaurEarly JurassicAkuyona i-dinosaur ngempela

I-Plesiopharos yayiyi-plesiosaur yasekuqaleni eyayibhukuda olwandle olufudumele lwase-Portugal eminyakeni ecishe ibe yizigidi eziyi-195 edlule. Yayinomzimba omude, amaphiko amane, nomsila omfushane, futhi yayisebenzisa amazinyo ayo abukhali ukubamba izinhlanzi nezinye izilwane zasolwandle.3 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-Plesiopharos ingenye yezilwane zasemanzini ezindala kakhulu neziphelele kakhulu ezake zatholwa e-Iberian Peninsula, ehlanganisa i-Portugal ne-Spain.1

Igama layo livela emagameni esiGreki asho 'eduze' kanye 'nesibani sasolwandle', ngoba yatholwa eduze kwesibani sasolwandle esibizwa ngokuthi i-Penedo da Saudade.1

Izinsalela zatholwa ngabazingeli bezinsalela ababili, uVitor Teixeira noAntónio Silva, abazinikela ku-Museu da Lourinhã ngonyaka ka-2017.1

I-Plesiopharos yayiphila ngesikhathi se-Sinemurian se-Early Jurassic, eminyakeni ecishe ibe yizigidi eziyi-199 kuya kweziyi-193 edlule, lapho uLwandle lwe-Atlantic lwalusanda kuqala ukwakheka.3 1

Ososayensi bacabanga ukuthi i-Plesiopharos yayiyilungu lokuqala kakhulu leqembu i-Plesiosauroidea, elihlanganisa ama-plesiosaur anentamo ende afika kamuva.1

Umfanekiso wethambo owaziwayo we-Plesiopharos uhlanganisa ama-vertebrae angu-22, izimbambo, izingxenye zokhalo namahlombe, namathambo amaphiko ayo.1

Isithombe sika-Plesiopharos 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: Plesiopharos
Iqanjwe ngu: Puértolas-Pascual et al. 20213
Iqembu: Ama-Plesiosaur
Umndeni / i-clade: Plesiosauroidea3
Ukuhlukaniswa: Plesiosauria > Sauropterygia3
Inkathi yamadwala: 200 kuya ku-193 wezigidi zeminyaka (Sinemurian)3
Amazwe: Portugal3
Izinsalela ezitholiwe: 1 ku-Paleobiology Database3
Ukutholakala: I-Plesiopharos yaqanjwa ngonyaka ka-2021 yiqembu lososayensi elaliholwa ngu-Eduardo Puértolas-Pascual. Isidumbu satholwa e-Praia da Concha e-Portugal futhi sanikelwa ku-Museu da Lourinhã.3 1
Kusaphikiswana ngakho: Ososayensi abaqiniseki ukuthi i-Plesiopharos ihlobene kakhulu yini nama-plesiosauroid anezintamo ezinde noma namanye amaqembu ama-plesiosaur akudala, ngoba isidumbu sayo sinengxube yezici ezivela ezinhlotsheni ezahlukene.1
