Cruralispennia
Cruralispennia wuxuu ahaa shimbir yar oo baalal leh oo noolaa qiyaastii 131 milyan oo sano ka hor meesha hadda ah dalka Shiinaha. Wuxuu lahaa baalal qariib ah oo lugaha kaga yaal oo aan shimbir kale oo hore ama ka dambeysay aysan lahayn!1
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Cruralispennia waxay lahayd laf dabo oo qaab majarafad ah, taas oo ah laf dabo isku darsantay oo loo malayn jiray inay ku jirto oo kaliya shimbiraha horumarsan. Tani waxay muujinaysaa in kooxo shimbireed oo kala duwan ay si gooni ah u yeesheen astaamo isku mid ah.1
Baalasheeda lugaha waxay ka duwanaayeen wax kasta oo hore loo arkay: salku wuxuu u ekaa silig adag, halka caaradduna ay ahayd mid jilicsan oo u qaybsantay dunta yaryar oo badan.1
In kasta oo Cruralispennia ay ku noolayd waqti aad u horeeya taariikhda shimbiraha, lafteeda garabka (coracoid) waxay ahayd mid aad u dhuuban, qaab inta badan laga helo shimbiraha xilligii dambe ee Cretaceous.1
Magaca Cruralispennia wuxuu la macno yahay 'baal lug' oo ku qoran Laatiin, sababtoo ah baalasha aan caadiga ahayn ee ku yaallay lafta lugta (tibiotarsus).1
Shimbirtan waxay lahayd 14 ilig oo ku yaalla daanka hoose, waana sababta magaceeda nooc ee buuxa uu yahay multidonta, oo macnaheedu yahay 'ilko badan'.1
Cruralispennia waxay la noolayd shimbiraha kale ee hore sida Protopteryx iyo Eoconfuciusornis isla deegaanka harada qadiimiga ah.1
Su'aalaha ugu badan ee ku saabsan Cruralispennia
?Intee in le'eg ayay ahayd Cruralispennia?
Cruralispennia waxay ahayd shimbir aad u yar, oo qiyaastii le'eg shimbirta loo yaqaan sparrow ee casriga ah. Baalasha lugaha waxay ahaayeen 12 ilaa 16 mm oo kaliya.23
?Xaggee ayay ku noolayd Cruralispennia?
Waxay ku noolayd meesha hadda loo yaqaan Shiinaha, agagaarka haro ku taal Sichakou Basin qiyaastii 131 milyan oo sano ka hor.2

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
