Protopteryx
Protopteryx wuxuu ahaa shimbir yar oo hore oo noolaa qiyaastii 131 milyan oo sano ka hor meesha hadda loo yaqaan Shiinaha. Wuxuu lahaa laba baal oo dabo oo dhaadheer oo u eg cajalad, kuwaas oo ka duwanaa baalasha shimbiraha casriga ah. Shimbirtan yar way duuli kartay waxayna u badan tahay inay cuni jirtay xayawaanno yaryar sida cayayaanka.14

Xaqiiqooyin xiiso leh
Protopteryx waa mid ka mid ah xubnihii ugu da'da weynaa uguna horeeyay ee kooxda Enantiornithes, kuwaas oo ahaa shimbiraha hore ee la noolaa dinosaurs-ka.1
Laba baal oo dabo oo dhexe ayaa ahaa kuwo u eg miisaan oo aan lahayn timo yaryar meel u dhow jirka, kaliya waxay lahaayeen timo yaryar oo caarada ah. Tani waxay la mid tahay baalasha dabada ee shimbirta cas ee casriga ah ee bird-of-paradise.12
Protopteryx wuxuu la ekaa shimbirta casriga ah ee starling, dhererka jirkiisuna wuxuu ahaa 10 sintimitir (3.9 inji) oo aan lagu darin baalasha dabada ee dhaadheer.1
Jirkiisu wuxuu ku daboolnaa saddex nooc oo baalal ah: baalal jilicsan, baalal duulimaad, iyo baalal dabo oo dhaadheer oo u eg cajalad.1
Baadadkii jilicsanaa ee Protopteryx waxay lahaayeen caarado fidsan oo qallafsan, halkii ay ka ahaan lahaayeen timo u eg kuwa shimbiraha casriga ah.1
Protopteryx wuxuu lahaa kanaal triosseal ah, oo ah qayb garabka ku taal oo ka caawin jirtay duulista, waana mid ka mid ah tusaalooyinkii ugu horreeyay ee shimbiraha.2
Su'aalaha ugu badan ee ku saabsan Protopteryx
?Intee in le'eg ayuu ahaa Protopteryx?
Qiyaastii 10 sentimitir oo dherer ah, iyadoo aan lagu xisaabin baalasha dabadiisa ee dhaadheer. Wuxuu qiyaastii la ekaa shimbirta starling ee casriga ah.1
?Maxuu cuni jiray Protopteryx?
Wuxuu u badnaa inuu cuno xayawaan yar yar sida cayayaanka. Ilkihiisu waxay la mid yihiin kuwa Archaeopteryx, taas oo soo jeedinaysa inuu lahaa cunto la mid ah.1
?Protopteryx ma duuli karay?
Haa, wuxuu u qalabaysnaa duulista. Wuxuu lahaa kanaal triosseal ah garabkiisa iyo baalal baalasha duulista ah oo aan isku mid ahayn, sida shimbiraha duula ee casriga ah.1
?Maxuu Protopteryx u lahaa baalal dabo oo dhaadheer?
Baalasha dabada ee dhaadheer ee u eg xariirta waxaa loo badinayaa in loo isticmaali jiray soo bandhigid, ee ma ahayn duulista. Waxay baalal yaryar ku lahaayeen oo kaliya caaradaha, taas oo la mid ah shimbirta red bird-of-paradise ee maanta.1
