Ikhadi le-Dino No. 0900 kwangu-2 027

Janavis

Igama lisho ukuthi: “inyoni ka-Janus, eqanjwe ngunkulunkulu wamaRoma wokuqala nokuphela”1

Udla: InyamaIzinyoni zakuqalaLate Cretaceous

I-Janavis yayiyinyoni enamazinyo eyaphila ekupheleni kwesikhathi sama-dinosaur. Yayingenye yezinyoni zokugcina ezinamazinyo, futhi ugebhezi lwayo lwalukwazi ukunyakaza njengolwenyoni yanamuhla.1

izinto ezinhle

Amaqiniso amnandi

I-Janavis yayiphila eminyakeni engaba izigidi ezingama-66.8 edlule, iminyaka engama-800,000 nje ngaphambi kokuba i-asteroid ebulala ama-dinosaur ifike.1

Amathambo ayo amaphiko ayengaphakathi engenalutho futhi egcwele umoya, njengezinyoni zanamuhla, okwenza ibe lula ukundiza.1

Izinsalela zatholwa emayini yase-Belgium ngo-2000 ngumzingeli wezinsalela u-Rudi Dortangs.1

I-Janavis yayinogebhezi olwalukwazi ukunyakazisa umhlathi ongaphezulu phezulu naphansi, okuyisici sezinyoni zanamuhla esibizwa ngokuthi i-neognathous palate.1

Ososayensi ekuqaleni babecabanga ukuthi ucezu logebhezi lwayo lwaluyithambo lephiko, kwaze kwaba yilapho isithombe se-CT ngo-2021 siveza iqiniso.1

I-Janavis yayinkulu kunesihlobo sayo i-Ichthyornis, inamaphiko angaba ngu-1.5 m ububanzi.1

Isithombe sika-Janavis 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-Janavis

?Yayinkulu kangakanani i-Janavis?

I-Janavis yayiyinyoni enkulu, inamaphiko angaba ngu-1.5 m ububanzi nesisindo esingaba ngu-1.5 kg.1 2

?Ingabe i-Janavis yayinamazinyo?

Yebo, i-Janavis yayinamazinyo. Yayingenye yezinyoni zokugcina ezinamazinyo ezake zaphila.1 2

?I-Janavis yaphila nini?

I-Janavis yayiphila eminyakeni engaba izigidi ezingu 66.8 edlule, ekupheleni kwenkathi ye-Cretaceous, iminyaka engu 800,000 kuphela ngaphambi kokuba i-asteroid ishaye umhlaba.1

?Ingabe i-Janavis yayikwazi ukundiza?

Yebo, i-Janavis yayikwazi ukundiza. Amathambo ayo amaphiko ayengaphakathi engenalutho futhi egcwele umoya, njengezinyoni zanamuhla, okwenza ibe lula ukundiza.1

Buza u-Rex ngo-Janavis

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.

Umchithi wezinganekwane

Inganekwane: Zonke izinyoni zasendulo zazinogebhezi oluqinile njengama-dinosaur.

Iqiniso: I-Janavis yayinogebhezi oluvumelana nezimo njengezinkukhu namadada anamuhla, okubonisa ukuthi ugebhezi olukwazi ukunyakaza lwavela kudala.1

Ochwepheshe bama-dino

Igama lesayensi: Janavis
Iqanjwe ngu: Benito et al. 20223
Iqembu: Izinyoni zakuqala
Umndeni / i-clade: Ichthyornithes3
Ukuhlukaniswa: Theropoda > Avialae3
Inkathi yamadwala: 72 kuya ku-66 wezigidi zeminyaka (Maastrichtian)3
Izakhiwo zamatshe: Maastricht3
Amazwe: I-Belgium3
Izinsalela ezitholiwe: 1 ku-Paleobiology Database3
Ukutholakala: Izinsalela zaqoqwa ngo-2000 ngumcwaningi wezinsalela u-Rudi Dortangs e-Belgium. Yaqala ukubikwa ngo-2002, futhi ngo-2022 ososayensi bayiqamba ngokuthi i-Janavis finalidens ngemuva kokuba izithombe ze-CT ziveze ukuthi iyini ngempela.1
Kusaphikiswana ngakho: Ososayensi bayaphikisana ngokuthi i-Janavis yayikwazi yini ukundiza kahle njengezinyoni zanamuhla, ngoba amathambo ayo amaphiko ayegcwele umoya kodwa ithambo layo lehlombe lalingenawo umkhono ojwayelekile.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.

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
