Ikhadi le-Dino No. 1723 kwangu-2 027

Styxosaurus

Igama lisho ukuthi: “isilwane esihuquzelayo somfula wabafileyo”1

Udla: InyamaAma-PlesiosaurLate CretaceousAkuyona i-dinosaur ngempela

I-Styxosaurus kwakuyisilwane sasolwandle esinentamo ende esayibhukuda ezilwandle ezingajulile ezazike zamboza iNyakatho Melika. Kwakungesiyo idinosaur, kodwa kwakuyi-plesiosaur, futhi yayisebenzisa amazinyo ayo abukhali ukubamba izinhlanzi nezilwane ezifana nezinkalankala.1 2

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

Ukubhukuda, isilinganiso

I-Styxosaurus yayidla ini?

Yayidla izinhlanzi, izilwane ezifana nezinkalankala, nezilwane zasolwandle ezibizwa nge-belemnites. Yayibamba inyamazane eshelelayo ngamazinyo ayo abukhali, ahlangene, bese iyigwinya iphelele.

izinto ezinhle

Amaqiniso amnandi

I-Styxosaurus yayinentamo ende kakhulu, enamathambo entamo angaphezu kwama-60, okuyenza ibe nenye yezintamo ezinde kunazo zonke kunoma yisiphi isilwane esake saphila.2

Yayihlala e-Western Interior Seaway, ulwandle olukhulu lwangaphakathi olwahlukanisa iNyakatho Melika kabili ngesikhathi sama-dinosaur.2

Ezinye izinsalela ze-Styxosaurus zake zacatshangwa ukuthi zingezesinye isilwane esibizwa nge-Hydralmosaurus, kodwa ososayensi manje bacabanga ukuthi ziyisilwane esisodwa.2

Isithombe sika-Styxosaurus 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-Styxosaurus

?Yayinkulu kangakanani i-Styxosaurus?

Yayicishe ibe ngamamitha ayi-11.3 ubude futhi inesisindo esicishe sibe amathani ayi-3.1. Intamo yayo yodwa yayicishe ibe ngamamitha ayi-5.25 ubude.4

?I-Styxosaurus yayidla ini?

Yayidla izinhlanzi, izilwane ezifana nezinkalankala, nezilwane zasolwandle ezibizwa nge-belemnites. Yayibamba inyamazane eshelelayo ngamazinyo ayo abukhali, ahlangene, bese iyigwinya iphelele.4

?I-Styxosaurus yayihlala nini?

Yayihlala ngesikhathi se-Late Cretaceous, eminyakeni eyizigidi eziyi-100 kuya kwayi-72 edlule.4 5

?Ingabe i-Styxosaurus yayinentamo ende?

Yebo, yayinentamo ende kakhulu enamathambo angaphezu kwama-60, okuyenza ibe nenye yezintamo ezinde kunazo zonke kunoma yisiphi isilwane.4 2

?Ingabe i-Styxosaurus iyidinosaur?

Cha, iyisilwane sasolwandle esibizwa nge-plesiosaur, esihlala olwandle, hhayi idinosaur.4

?I-Styxosaurus yatholakala kuphi?

Izinsalela zatholakala eNyakatho Melika, ikakhulukazi e-Kansas, e-South Dakota, e-Nebraska, nase-Wyoming, emadwaleni ayekade engaphansi kolwandle olungajulile.4 5

Ochwepheshe bama-dino

Igama lesayensi: Styxosaurus
Iqanjwe ngu: Welles 19435
Iqembu: Ama-Plesiosaur
Umndeni / i-clade: Elasmosauridae5
Ukuhlukaniswa: Plesiosauria > Elasmosauridae > Sauropterygia5
Inkathi yamadwala: 90 kuya ku-72 wezigidi zeminyaka (Coniacian / Campanian)5
Izakhiwo zamatshe: Pierre Shale, Niobrara5
Amazwe: USA5
Izinsalela ezitholiwe: 8 ku-Paleobiology Database5
Eyaziwa nangokuthi: Hydralmosaurus (amagama amadala manje abalwa njengesilwane esisodwa)5
Kusaphikiswana ngakho: Ososayensi basaphikisana ngokuthi zingaki izinhlobo ze-Styxosaurus ezazikhona, nokuthi ingabe ezinye izinsalela zingezalo hlobo noma ngezinye izilwane zohlobo lwe-elasmosaurid.2
