Maiaspondylus

Igama lisho ukuthi: “umgogodla kamama onakekelayo”1
Udla: InyamaAma-ichthyosaurEarly CretaceousAkuyona i-dinosaur ngempela

U-Maiaspondylus wayeyisilwane sasolwandle esaphila olwandle, hhayi idinosaur. Wayeyisilwane esibizwa nge-ichthyosaur, umzingeli obhukuda ngokushesha onomlomo omude namazinyo abukhali. Izinsalela zibonisa ukuthi wayezala amaphuphu aphilayo, njengoba kwenza imikhomo nama-dolphin namuhla.1

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

izinto ezinhle

Amaqiniso amnandi

1

U-Maiaspondylus usho ukuthi 'umgogodla kamama onakekelayo' ngoba kwatholakala insalela enezimbungu ezimbili ngaphakathi kwesilwane esikhulile, okubonisa ukuthi wayezala amaphuphu aphilayo.1

2

Izimbungu ezatholakala ngaphakathi kwesilwane esikhulile yizimbungu ze-ichthyosaur ezincane kakhulu nezincane kunazo zonke ezake zatholakala.1

3

I-Maiaspondylus yayiphila eminyakeni engaba ngu-110 ezigidi edlule ngesikhathi se-Early Cretaceous.1

4

Izinsalela zawo zatholakala okokuqala ku-Loon River Formation e-Northwest Territories yase-Canada.1

5

U-Maiaspondylus wayenohlelo olukhethekile lwamathambo egebhezi: i-jugal ne-maxilla zazigqagqana kakhulu, okwasiza ososayensi ukuba bawuhlukanise nezinye izilwane ezifana nama-ichthyosaur.2

6

Amazinyo awo ayenemiqhele ebushelelezi kanye ne-cementum (isikhumba sezimpande), futhi ayegobile ebheke ngaphakathi ngaselimini.2

7

Ithambo lengalo (humerus) lika-Maiaspondylus lalinamaqhuzu amathathu ekugcineni kwemisipha, lapho iqhuzu eliphakathi lincane kunezingaphandle.2

Kwenziwe nge-AIIsithombe sika-Maiaspondylus esenziwe nge-AI
Isithombe sika-Maiaspondylus 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.

Imibuzo ebuzwa kakhulu mayelana no-Maiaspondylus

?Wayengakanani u-Maiaspondylus?

Akekho owazi ngokuqinisekile ngoba akukho mathambo aphelele atholakele. Izinsalela ezaziwayo zihlanganisa amathambo acishe aphelele kanye nemigogodla evela ezilwaneni ezikhulile, kodwa ososayensi abakakalilinganisi ubude bawo obuphelele.1

?Ingabe u-Maiaspondylus wayezala amaphuphu aphilayo?

Yebo. Insalela ka-Maiaspondylus omdala yatholakala inezimbungu ezimbili ngaphakathi, okufakazela ukuthi wayezala amaphuphu aphilayo, njengemikhomo nama-dolphin.13

?Watholakala kuphi u-Maiaspondylus?

Izinsalela zawo zatholakala okokuqala ku-Loon River Formation e-Northwest Territories yase-Canada. Kamuva, izinsalela zatholakala nase-England nase-Russia.1

Kusaphikiswana ngakho
Ososayensi basaphikisana ngokuthi u-Maiaspondylus uhlobene kanjani ngqo nezinye izilwane ezifana nama-ichthyosaur, ikakhulukazi uhlobo lwe-Platypterygius.1
