Xaqiiqooyin xiiso leh
Stellasaurus wuxuu lahaa gees dheer oo toosan oo sanka ah iyo kuus kuus yar oo indhihiisa ka sarreeya, taas oo la mid ah qaraabadiisa Styracosaurus.23
Qaybta dambe ee madaxiisa (frill) waxay lahayd qodxo dhaadheer oo loo yaqaan P3, laakiin qodxaha kale way ka gaabnaayeen, taas oo ka dhigaysa mid muuqaal gaar ah leh.23
Stellasaurus wuxuu noolaa qiyaastii 75.2 milyan oo sano ka hor, xilligii dambe ee Cretaceous.3
Saynisyahannadu waxay u malaynayaan in Stellasaurus laga yaabo inuu ahaa nooc kala guur ah, taas oo macnaheedu yahay inuu muujinayo astaamo u dhexeeya dinosaurs-kii geesaha lahaa ee hore iyo kuwa ka dambeeyay.23
Fossilkii kaliya ee la yaqaan waa qayb ka mid ah madaxa, oo laga helay aagga Landslide Butte ee u dhow xadka Maraykanka iyo Kanada.2
Stellasaurus wuxuu ka mid yahay koox loo yaqaan centrosaurines, kuwaas oo ah dinosaurs gees leh oo leh geeso waaweyn oo sanka ah iyo madax qurxoon.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
