Himeoolithus
Himeoolithus wuxuu ahaa dinosaur yar oo hilib-cun ah oo ku noolaa meesha hadda loo yaqaan Japan qiyaastii 110 milyan oo sano ka hor. Waxaa lagu yaqaanaa ukuntiisa, taas oo ka mid ah ukumaha theropod ee ugu yar ee abid la helo, qiyaastii cabbirka ukunta quail-ka. Ukumahani waxay muujinayaan in dinosaur-rada yaryar ay la noolaayeen kuwa waaweyn!2
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Ukumaha Himeoolithus waa ukumaha theropod ee ugu yar ee aan shimbir ahayn ee la yaqaan, iyadoo miisaankoodu lagu qiyaasay 9.9 grams oo keliya, qiyaastii cabbirka ukunta quail-ka casriga ah.1
Ukumuhu waa kuwo dhaadheer marka loo eego cabbirkooda, iyadoo saamiga dhererka iyo ballaca uu yahay 2.25, taas oo u badan ukumaha theropod-ka waaweyn.1
Buulka waxaa la helay isagoo meeshiisii yaalla, biyaha ama dabayshu ma qaadin, sababtoo ah inta badan jajabka qolofka ukunta ayaa u jeeday xagga sare, taas oo dhacda marka ay meeshooda ku jabaan.2
In ka badan 1,300 oo jajab qolof ukun ah oo ka yimid Himeoolithus ayaa laga helay Kamitaki Egg Quarry, oo ay weheliyaan ukumo kale oo theropod yar yar ah.2
Kala duwanaanshaha badan ee ukumaha theropod-ka yaryar ee goobtan ayaa ka dhigaya mid ka mid ah meelaha ugu kala duwan ee ukumaha Early Cretaceous ee la yaqaan.2

Burinta khuraafaadka
Khuraafaad: Dadka qaar waxay u malaynayaan in dhammaan dinosaur-radu ay ahaayeen kuwo waaweyn, laakiin Himeoolithus wuxuu muujinayaa in qaar badan ay ahaayeen kuwo yaryar.
Runta: Ukumaha Himeoolithus waa kuwo yaryar, dinosaur-kii dhigayna wuxuu u badnaa mid yar, taas oo muujinaysa in dinosaur-radu ay lahaayeen cabbirro kala duwan.2
