Xiangornis

Igama lisho ukuthi: “inyoni endiza ngokukhululeka”1

Udla: InyamaIzinyoni zakuqalaEarly Cretaceous

I-Xiangornis yayiyinyoni yasendulo eyaphila eminyakeni engaba yizigidi eziyi-120 edlule. Yayinengxube yezici ezivela emaqenjini amabili amakhulu ezinyoni zakuqala, okwayenza yaba isidalwa esiyindida nesikhethekile. Amathambo ayo amaphiko ayesexhumene kakade njengasezinyonini zanamuhla, okwayisiza ukuba indize ngamandla.1 2

Amaqiniso amnandi

I-Xiangornis ingeyeqembu elibizwa ngokuthi i-Enantiornithes, okwakuyizinyoni ezazivame kakhulu ngesikhathi se-Cretaceous.3 1

Amathambo amaphiko ayo (carpometacarpus) ayesehlangene ngokuphelele, kokubili eduze komzimba nakude nawo, njengasezinyonini zanamuhla.1 2

I-Xiangornis yayinendawo enkulu ephikweni layo, okuyisigaxa samathambo esasisiza ukunamathisela imisipha nemisipha ukuze indize ngamandla.1 2

Le nyoni ikhombisa ukuthi ezinye izici ezazicabangelwa ukuthi ngezezinyoni zanamuhla kuphela, empeleni zavela kudala futhi ngokuhlukile kuma-enantiornithines.1 2

Igama elithi Xiangornis livela emagameni olimi lwesi-Mandarin asho 'ukundiza ngokukhululeka' kanye negama lesi-Greek elisho inyoni.1 2

I-Xiangornis yaphila ngesikhathi se-Aptian, eminyakeni engaba yizigidi eziyi-121 kuya kweziyi-113 edlule, endaweni esiyi-Liaoning, e-China namuhla.3

Isithombe sika-Xiangornis 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.

Buza u-Rex ngo-Xiangornis

Rex uphendula imibuzo mayelana naleli khasi kuphela. Imibuzo engu-10 ngenyanga.

Rex uyi-AI futhi angenza amaphutha. Usebenza kumaseva ase-EU futhi imibuzo ayilokothi ilondolozwe. Ungalokothi uthayiphe igama lakho noma ezinye izinto zakho.

Ochwepheshe bama-dino

Igama lesayensi: Xiangornis
Iqanjwe ngu: Hu et al. 20124
Iqembu: Izinyoni zakuqala
Umndeni / i-clade: Enantiornithes4
Ukuhlukaniswa: Theropoda > Avialae4
Inkathi yamadwala: 121 kuya ku-113 wezigidi zeminyaka (Aptian)4
Izakhiwo zamatshe: Jiufotang4
Amazwe: I-China4
Izinsalela ezitholiwe: 1 ku-Paleobiology Database4
Ukutholakala: I-Xiangornis yaqanjwa ngu-Hu nozakwabo ngonyaka ka-2012 ngokusekelwe kuhlaka lwamathambo olwatholakala e-Jiufotang Formation e-Liaoning, e-China. Lezi zinsalela zihlanganisa amathambo amaphiko namahlombe.3 1
Kusaphikiswana ngakho: Ososayensi basaphikisana ngokuthi i-Xiangornis ingabe iyinyoni yohlobo lwe-enantiornithine ngempela, noma ingabe isemkhawulweni phakathi kwe-enantiornithines ne-ornithuromorphs (iqembu elihlanganisa izinyoni zanamuhla).1 2

Yonke imininingwane ekuleli khasi inenombolo ekhomba umthombo wayo. Uma kukhona esikwenze kabi, siyaxolisa, singabalandeli bama-dino, hhayi iphephabhuku lesayensi. Sitshele ku-[email protected] futhi sizokulungisa.

Rex ulambile! I-Dino Wiki iphrojekthi kababa wendodana yakhe ethanda ama-dino, imahhala ngaphandle kwezikhangiso nezilandeleli. Abantu abadala bangaphakela u-Rex ukudla okulula ukuze basize ukuyigcina iku-inthanethi.Phakela u-Rex
