Sinornis
Sinornis wuxuu ahaa shimbir yar oo noolaa qiyaastii 120 milyan oo sano ka hor meesha hadda loo yaqaan Shiinaha. Waxay la ekayd shimbirta loo yaqaan sparrow, waxayna awood u lahayd inay duusho oo ay laamo ku fariisato sida shimbiraha maanta. Lafaha laga helay waxay ka caawiyeen saynisyahannada inay fahmaan sida shimbiruhu uga soo farcameen dinosaurs-ka.21
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Sinornis wuxuu lahaa laf curcur oo gaar ah oo u oggolaanaysay inay si xoog leh u laabto, taas oo u sahlaysay inay baalasheeda si adag u laabato inta ay duulayaan ama nasanayaan.1
Si ka duwan shimbiraha maanta, Sinornis waxay lahayd faro gooni ah oo leh cidiyo yaryar oo ku yaal faraha koowaad iyo labaad.1
Sinornis waxay lahayd suul dhabarka u jeeda oo leh cidi weyn, taas oo ka caawisay inay laamaha ku fariisato.1
Lafaha naaska iyo garabka waxay u dhisnaayeen si ay u qaadaan muruqyo duulimaad oo xoog leh, taas oo la mid ah shimbiraha maanta.1
Sinornis weli waxay lahayd astaamo hore sida gacmo dabacsan, lafaha miskaha oo gaar ah, iyo lafaha caloosha (gastralia), kuwaas oo ay la wadaagto shimbirtii hore ee Archaeopteryx.21
Lafaha Sinornis waxaa helay beeraley Shiineys ah ka hor 1992, saynisyahannada Paul Sereno iyo Rao Chenggang ayaana magacaabay oo sharraxay.1
Su'aalaha ugu badan ee ku saabsan Sinornis
?Intee in le'eg ayuu ahaa Sinornis?
Wuxuu la ekaa shimbirta sparrow. Lafahiisu waxay ahaayeen cabbirka sparrow, markaa wuxuu ahaa shimbir aad u yar.12
?Sinornis ma duuli karay?
Haa. Wuxuu lahaa laf naas oo ballaaran iyo qaab-dhismeed garab oo loogu talagalay muruqyo duulimaad oo xoog leh, iyo laf curcur oo gaar ah oo u oggolaanaysay inay baalasheeda laabato, markaa wuxuu u duuli karay sida shimbiraha maanta.1
?Sinornis ma lahaa ilko?
Haa. Madaxiisu wuxuu lahaa af gaaban oo ilko leh, oo la mid ah shimbirtii hore ee Archaeopteryx.1
?Goorma ayuu noolaa Sinornis?
Wuxuu noolaa qiyaastii 120 milyan oo sano ka hor, xilligii Early Cretaceous.1

- Sinornis waxaa magacaabay Paul Sereno iyo Rao Chenggang sanadkii 1992. Lafaha waxaa laga helay Jiufotang Formation oo ku taal Liaoning, Shiinaha, waxaana markii hore loo maleeyay inay yihiin 135 milyan oo sano, laakiin cilmi-baaris dambe ayaa muujisay inay yihiin qiyaastii 120 milyan oo sano.12
- Wali waa la isku khilaafsan yahay
- Saynisyahannadu weli way ku doodayaan in shimbir kale oo isla aaggaas laga helay, oo la yiraahdo Cathayornis, ay tahay isla nooca Sinornis iyo in kale.1

Xaqiiqo kasta oo boggan ku taal waxay leedahay lambar tilmaamaya halka ay ka timid. Haddii aan wax khaldnay, raali ahow, waxaan nahay taageerayaasha dino, ma nihin joornaal saynis. Noo sheeg [email protected] waana hagaajin doonnaa.
Rex wuu gaajaysan yahay! Dino Wiki waa mashruuc aabbe u sameeyay wiilkiisa dino-jecel, bilaash ah oo aan lahayn xayeysiis iyo qalab raad-raac. Dadka waaweyn waxay Rex siin karaan cunto fudud si ay uga caawiyaan inuu khadka ku sii jiro.Quudi Rex
