Ikhadi le-Dino No. 1363 kwangu-2 027

Pantosaurus

Igama lisho ukuthi: “isibankwa sonke”1

Udla: InyamaAma-PlesiosaurLate JurassicAkuyona i-dinosaur ngempela

I-Pantosaurus yayiyisilwane sasolwandle esinentamo ende esayibhukuda olwandle olungajulile olwalukade lumboze ingxenye ye-North America. Yayingeyona idinosaure, kodwa yayiyi-plesiosaur, uhlobo lwesilwane esizingelayo olwandle. Yayisebenzisa izimpiko zayo ezine ukubhukuda emanzini nokubamba izinhlanzi nezinye izilwane.1 2

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

I-Pantosaurus yayidla ini?

I-Pantosaurus yayidla izinhlanzi nezinye izilwane zasolwandle. Umfanekiso wamathambo wengane ye-ichthyosaur watholakala ngaphakathi esiswini se-Pantosaurus, okubonisa ukuthi yayidla ama-ichthyosaur.

Amaqiniso amnandi

I-Pantosaurus yayinentamo ende kakhulu enamathambo entamo aphakathi kuka-35 no-40, abizwa ngokuthi ama-cervical vertebrae. Lawa mathambo ayecishe abe made njengoba ayebanzi, okwasiza ukwenza intamo ikwazi ukunyakaza kalula.3

Igama elithi Pantosaurus ekuqaleni lalingu-'Parasaurus', kodwa lelo gama lase lisetshenziselwa esinye isilwane, ngakho ososayensi balishintsha.1

I-Pantosaurus yayiphila olwandle i-Sundance Sea, ulwandle olungajulile olwalumboze izingxenye zase-Wyoming eminyakeni eyizigidi edlule.1

Ososayensi bacabanga ukuthi i-Pantosaurus kungenzeka yayizala amaphuphu aphilayo, hhayi ukubeka amaqanda, ngoba yayiphila emanzini.2

Izimpiko zangaphambili ze-Pantosaurus zazikhethekile: ithambo le-radius lalingaphezu kakhulu futhi libanzi kune-ulna, okwasiza ukuyiqondisa emanzini.3

Umfanekiso wamathambo wengane ye-ichthyosaur (esinye isilwane sasolwandle) watholakala ngaphakathi esiswini se-Pantosaurus, okubonisa ukuthi yayidla ezinye izilwane zasolwandle.1

Isithombe sika-Pantosaurus 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.

ubuzile

Imibuzo ebuzwa kakhulu mayelana no-Pantosaurus

?I-Pantosaurus yayidla ini?

I-Pantosaurus yayidla izinhlanzi nezinye izilwane zasolwandle. Umfanekiso wamathambo wengane ye-ichthyosaur watholakala ngaphakathi esiswini se-Pantosaurus, okubonisa ukuthi yayidla ama-ichthyosaur.1 3

?Yayinkulu kangakanani i-Pantosaurus?

I-Pantosaurus yayiyi-plesiosaur encane, kodwa ubukhulu bayo obuqondile abwaziwa emithonjeni. Yayinentamo ende kakhulu enamathambo entamo aphakathi kuka-35 no-40.1 3

?I-Pantosaurus yayiphila nini?

I-Pantosaurus yayiphila ngesikhathi se-Late Jurassic, eminyakeni eyizigidi ezi-163 kuya kwezi-157 edlule.1 4

?Ingabe i-Pantosaurus yayiyidinosaure?

Cha, i-Pantosaurus yayingeyona idinosaure. Yayiyi-plesiosaur, uhlobo lwesilwane sasolwandle esasiyiphila olwandle.1

Umchithi wezinganekwane

Inganekwane: Abanye abantu bacabanga ukuthi i-Pantosaurus yayiyidinosaure ngoba yayiphila ngesikhathi esifanayo nezidinosaure.

Iqiniso: I-Pantosaurus yayiyi-plesiosaur, isilwane sasolwandle, hhayi idinosaure. Izidinosaure zaziphila emhlabathini, kanti i-Pantosaurus yayibhukuda olwandle.1

Ochwepheshe bama-dino

Igama lesayensi: Pantosaurus
Iqanjwe ngu: Marsh 18934
Iqembu: Ama-Plesiosaur
Umndeni / i-clade: Cryptoclididae4
Ukuhlukaniswa: Plesiosauria > Sauropterygia4
Inkathi yamadwala: 162 kuya ku-155 wezigidi zeminyaka (Oxfordian)4
Izakhiwo zamatshe: Sundance4
Amazwe: USA4
Izinsalela ezitholiwe: 6 ku-Paleobiology Database4
Eyaziwa nangokuthi: Parasaurus (amagama amadala manje abalwa njengesilwane esisodwa)4
Ukutholakala: I-Pantosaurus yatholakala okokuqala e-Wyoming ngasekupheleni kwawo-1800 ngu-Othniel Charles Marsh. Wayibiza nge-Parasaurus ngo-1891, kodwa washintsha igama wayibiza nge-Pantosaurus ngo-1893 ngoba igama elidala lase lisetshenziswa.1 3
Kusaphikiswana ngakho: Ososayensi basaphikisana ngokuthi ngabe amanye amathambo angawase-Pantosaurus noma awenye i-plesiosaur efanayo, ngoba ugebhezi alwaziwa.3
