Sisteronia
Sisteronia wuxuu ahaa xamaarato badeed si degdeg ah u dabaasha oo ku noolaa badaha xilligii Cretaceous. Wuxuu lahaa ilko fiiqan oo uu ku qabsado kalluunka yaryar iyo squid-ka. Sisteronia wuxuu ahaa ichthyosaur, ee ma ahayn dinosaur, wuxuuna u ekaa xoogaa dolphin-ka casriga ah.12
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Sisteronia wuxuu lahaa ilko qaab afar gees ah u samaysan, taas oo aan caadi ahayn ichthyosaurs-ka dhexdiisa.2
Wuxuu noolaa xilligii Albian iyo horraantii Cenomanian ee Cretaceous, qiyaastii 112 ilaa 100 milyan oo sano ka hor.2
Sisteronia waxaa laga yaqaanaa lafo laga helay England, France, iyo Russia, taas oo muujinaysa inuu ku noolaa badaha galbeedka Yurub.3
Ichthyosaur-kan wuxuu ka tirsanaa kooxda Platypterygiinae, kuwaas oo ahaa ichthyosaurs-kii ugu dambeeyay ee noolaa ka hor intaysan dabar go'in.2
Magaca Sisteronia wuxuu ka yimid magaalada Sisteron ee dalka France, meel u dhow halkaas oo laga helay qaar ka mid ah lafahiisa.1
Sisteronia wuxuu lahaa qayb kor u kacsan oo ku taal dabaqa foramen magnum (daloolka madaxa ee xadhigga laf-dhabarta), taas oo ah astaamo gaar ah oo aan lagu arkin ichthyosaurs-ka kale.2

- Wali waa la isku khilaafsan yahay
- Saynisyahannadu weli way ka doodayaan sida ay u kala duwanaayeen ichthyosaurs-ka xilligii dambe ee Cretaceous, iyo haddii Sisteronia uu qayb ka ahaa meel ballaaran oo Yurub ah oo ay ku noolaayeen ichthyosaurs kala duwan.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
