Changmaornis

Magacu wuxuu ka dhigan yahay: “Shimbirta Changma”1

Cunay: HilibShimbiraha hore (xilligii dinos-ka)Cretaceous-kii hore

Changmaornis wuxuu ahaa dinosaur yar oo u eg shimbir, kaas oo noolaa qiyaastii 120 milyan oo sano ka hor. Wuxuu lahaa lugo dhaadheer iyo cidiyo aan fiiqneyn, wuxuuna u badnaa inuu waqtigiisa badankiisa ku qaato socodka dhulka ama dhex-socodka biyaha.1

Xaqiiqooyin xiiso leh

Changmaornis waxaa lagu yaqaannaa qayb ka mid ah lafaha jirka oo ay ku jiraan lafaha cagta, lafaha dhabarka, iyo qayb ka mid ah misigta.1

Faraha cagta ee saddexaad ayaa ahaa kii ugu dheeraa, taas oo ka duwan qaraabadiisa Gansus, halkaas oo faraha afraad uu ahaa kii ugu dheeraa.1

Changmaornis wuxuu lahaa cidiyo aan fiiqneyn oo cagaha ah, taas oo muujinaysa inuusan aad u fuulin geedaha.1

Wuxuu la noolaa shimbiraha kale ee hore sida Gansus, Yumenornis, iyo Jiuquanornis isla aagga harada qadiimiga ah.1

Saynisyahannadu waxay u maleynayaan in Changmaornis laga yaabo inuu ahaa mid biyaha ku noolaa, sida shimbirta loon ama grebe ee casriga ah, sababtoo ah lafaha cagtiisu waxay u eg yihiin kuwo la mid ah.1

Magaca Changmaornis wuxuu ka yimid Magaalada Changma ee Shiinaha, halkaas oo fossil-ka laga soo saaray.1

Sawirka Changmaornis oo uu sameeyay AI — Sawir uu sameeyay AI oo muujinaya sida Changmaornis u ekaan karay, oo uu kombuyuutarku ka sameeyay waxa ay saynisyahannadu yaqaaniin. Waa qiyaas: xayawaanka dhabta ah waxaa laga yaabaa inuu u ekaa si ka duwan, qofna ma garanayo midabadiisa dhabta ah.

Khubarada dino

Magaca sayniska: Changmaornis
Waxaa magacaabay: Wang et al. 20132
Koox: Shimbiraha hore (xilligii dinos-ka)
Qoyska / kooxda: Ornithuromorpha2
Kala soocidda: Theropoda > Avialae2
Xilligii dhagaxyada: 121 ilaa 113 milyan oo sano (Aptian)2
Dhagaxyada: Xiagou2
Waddamada: China2
Diiwaanka fossil-ka: 1 oo ku jira Paleobiology Database2
Daahfurka: Changmaornis waxaa magacaabay Wang Y.-M. iyo asxaabtiisa sannadkii 2013, iyadoo lagu saleynayo fossil laga helay Xiagou Formation ee Gansu, Shiinaha. Magaca nooca houi wuxuu sharfayaa Professor Lian-Hai Hou, oo magacaabay shimbirtii ugu horreysay ee Mesozoic ee laga helo Shiinaha.1
Wali waa la isku khilaafsan yahay: Saynisyahannadu ma hubo in Changmaornis uu inta badan ku noolaa dhulka iyo inuu biyaha ku noolaa, sababtoo ah lafaha jirkiisu dhammaystir ma aha.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
