Sinornis

Igama lisho ukuthi: “Inyoni yaseChina”1

Udla: InyamaIzinyoni zakuqalaEarly Cretaceous

Sinornis kwakuyinyoni encane eyayiphila eminyakeni engaba izigidi eziyi-120 edlule kuleyo ndawo okuyizwe laseChina namuhla. Yayilingana nenyoni i-sparrow futhi yayikwazi ukundiza nokuhlala ezihlahleni njengezinyoni zanamuhla. Amathambo ayo asiza ososayensi ukuba baqonde ukuthi izinyoni zavela kanjani ezilwaneni ezinkulu ezazibizwa ngama-dinosaur.2 1

izinto ezinhle

Amaqiniso amnandi

Sinornis yayinethambo lesihlakala elikhethekile elinomsele owawuyivumela ukuba igobe isihlakala sayo kakhulu, okwenza ikwazi ukugoqa amaphiko ayo ngokuqinile ngenkathi indiza noma iphumule.1

Ngokungafani nezinyoni zanamuhla, Sinornis yayinamathambo eminwe ahlukene anezinzipho ezincane emunweni wayo wokuqala nowesibili.1

Sinornis yayinomunwe ongemuva (hallux) owawukwazi ukubamba kahle ngenzipho enkulu, okwayisiza ukuba ihlale ezihlahleni.1

Ithambo layo lesifuba kanye nezakhiwo zamahlombe kwakwakhelwe imisipha enamandla yokundiza, okufana nezinyoni zanamuhla.1

Sinornis yayisenezici zakudala ezifana nesandla esiguquguqukayo, ithambo le-pubis elinezinyawo, nezimbambo zesisu (gastralia), okwakuyizici eyayizihlanganyela nenyoni yakudala i-Archaeopteryx.2 1

Ithambo le-Sinornis latholakala ngumlimi waseChina ngaphambi konyaka we-1992, kwathi ososayensi uPaul Sereno noRao Chenggang bayiqamba futhi bayichaza.1

Isithombe sika-Sinornis 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-Sinornis

?Yayinkulu kangakanani i-Sinornis?

Yayilingana nenyoni i-sparrow. Ithambo layo lalingangesayizi ye-sparrow, ngakho yayiyinyoni encane kakhulu.1 2

?Ingabe i-Sinornis yayikwazi ukundiza?

Yebo. Yayinesifuba esibanzi nezakhiwo zamahlombe zemisipha enamandla yokundiza, nethambo lesihlakala elikhethekile elayivumela ukuba igoqe amaphiko ayo, ngakho yayikwazi ukundiza njengezinyoni zanamuhla.1

?Ingabe i-Sinornis yayinamazinyo?

Yebo. Ugebhezi lwayo lwalunomlomo omfushane onamazinyo, ofana nenyoni yakudala i-Archaeopteryx.1

?I-Sinornis yayiphila nini?

Yayiphila eminyakeni engaba izigidi eziyi-120 edlule, phakathi nenkathi ye-Early Cretaceous.1

Buza u-Rex ngo-Sinornis

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: Sinornis
Iqanjwe ngu: Sereno and Rao 19923
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: Sinornis yaqanjwa nguPaul Sereno noRao Chenggang ngonyaka we-1992. Ithambo layo latholakala eJiufotang Formation eLiaoning, eChina, futhi ekuqaleni kwakucatshangwa ukuthi ineminyaka eyizigidi eziyi-135, kodwa ucwaningo olwalandela lwabonisa ukuthi ineminyaka engaba izigidi eziyi-120.1 2
Kusaphikiswana ngakho: Ososayensi basaphikisana ngokuthi enye inyoni evela kuleyo ndawo efanayo, i-Cathayornis, ingabe iyinhlobo efanayo ne-Sinornis noma iyinhlobo ehlukile.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
