Eocathayornis

Igama lisho ukuthi: “i-Cathayornis yasekuseni, ebhekisela ekwakhekeni kwayo okuyisisekelo uma iqhathaniswa ne-Cathayornis”1

Udla: InyamaIzinyoni zakuqalaEarly Cretaceous

I-Eocathayornis yayiyinyoni encane yakuqala eyaphila ngesikhathi se-Age of Dinosaurs. Yayikwazi ukushaya amaphiko ayo ngamandla futhi indize njengenyoni yanamuhla, kodwa yayisenawo amazinyo nezinzipho emaphikweni ayo.2

Amaqiniso amnandi

I-Eocathayornis yayinozipho oluncane emunweni wayo wesithathu wephiko, kodwa ezinye izipho ezimbili zamaphiko zazisakhona.2

Ithambo layo le-radius lalicishe libe zintathu kwezine ububanzi bethambo layo le-ulna, okwasiza ukwenza iphiko layo liqine ukuze likwazi ukushaya.2

I-sternum (ithambo lesifuba) yayinethambo eliphakamileyo kanye nezicubu ezimbili ezinde ezikhomba emuva, okwakuyizinto ezisiza ekundizeni.2

I-Eocathayornis yayicishe ilingane ne-Cathayornis, enye inyoni yakudala evela endaweni efanayo lapho kwatholakala khona izithombe.2

Yaphila eminyakeni eyizigidi ezingaba yi-120 edlule, phakathi nenkathi ye-Early Cretaceous.1

Isithombe esisodwa kuphela esaziwayo yikhakhayi nengxenye engenhla yomzimba ezigcinwe njengemifanekiso etsheni, ehlukaniswe yaba izingcezu ezimbili.1

Isithombe sika-Eocathayornis 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: Eocathayornis
Iqanjwe ngu: Zhou 20023
Iqembu: Izinyoni zakuqala
Umndeni / i-clade: Enantiornithes3
Ukuhlukaniswa: Theropoda > Avialae3
Inkathi yamadwala: 121 kuya ku-113 wezigidi zeminyaka (Aptian)3
Izakhiwo zamatshe: Jiufotang3
Amazwe: I-China3
Izinsalela ezitholiwe: 1 ku-Paleobiology Database3
Ukutholakala: Isithombe esidala satholakala ngo-1994 ngu-Zhou Zhonghe e-Jiufotang Formation e-Liaoning, e-China. U-Zhou waletha igama elithi Eocathayornis walkeri ngo-2002, ehlonipha u-Cyril Alexander Walker ngomsebenzi wakhe ngezinyoni zakudala i-Enantiornithes.1 2
Kusaphikiswana ngakho: Ososayensi abaqiniseki ngokuthi i-Eocathayornis ihlobene kanjani nezinye izinyoni zakudala, kodwa kucatshangwa ukuthi yayiyisidalwa esilula kune-Cathayornis.1

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.
