Austrocheirus

Magacu wuxuu ka dhigan yahay: “gacanta koonfureed”1

Cunay: HilibDino-yada hilibka cunaCretaceous-kii dambe

Austrocheirus wuxuu ahaa dinosaur hilib-cun ah oo ku noolaa meesha hadda loo yaqaan Argentina xilligii Late Cretaceous. Wuxuu la ekaa dhererka baska dugsiga wuxuuna lahaa gacmo aan yaryareyn sida kuwa qaraabadiisa. Saynisyahannadu weli way ku muransan yihiin nooca theropod uu ahaa.1 2

Xaqiiqooyin xiiso leh

Austrocheirus waxaa laga yaqaan oo kaliya qayb ka mid ah gacanta, lafaha lugta, lafaha cagta, iyo qaybo ka mid ah laf-dhabarta.1

Magaciisu wuxuu ka dhigan yahay 'gacanta koonfureed' sababtoo ah lafahiisa waxaa laga helay qaybta koonfureed ee Koonfurta Ameerika.1

Si ka duwan abelisauroids kale oo badan, Austrocheirus ma lahayn gacmo yaryar oo duuduuban. Gacmihiisu waxay ahaayeen kuwo cabbirkoodu buuxo.2

Saynisyahannada qaar waxay u maleynayaan in Austrocheirus laga yaabo inuusan ahayn abelisauroid haba yaraatee. Waxay yiraahdaan wuxuu noqon karaa theropod guud oo aan qoyskiisa saxda ah la aqoon.1

Lafaha kaliya ee la yaqaan ee Austrocheirus waxaa la helay 17-kii Maarso, 2002, meel la yiraahdo Hoyada Arroyo Seco ee Argentina.2

Daraasad la sameeyay 2024 ayaa soo jeedisay in Austrocheirus laga yaabo inuu ka tirsan yahay koox la yiraahdo Berthasauridae, kuwaas oo ah qaraabo dhow oo abelisauroids ah.1

Sawirka Austrocheirus oo uu sameeyay AI — Sawir uu sameeyay AI oo muujinaya sida Austrocheirus u ekaan karay, oo uu kombuyuutarku ka sameeyay waxa ay saynisyahannadu yaqaaniin. Waa qiyaas: xayawaanka dhabta ah waxaa laga yaabaa inuu u ekaa si ka duwan, qofna ma garanayo midabadiisa dhabta ah.

waad weydiisay

Su'aalaha ugu badan ee ku saabsan Austrocheirus

?Intee ayay la ekayd Austrocheirus?

Austrocheirus wuxuu ahaa theropod dhexdhexaad ah, dhererkiisuna wuxuu ahaa qiyaastii 5.5 ilaa 6.5 m (18 ilaa 21 feet). Taasi waa qiyaastii dhererka baska dugsiga.1

?Maxaa Austrocheirus loogu yeeraa 'gacanta koonfureed'?

Magaciisu wuxuu ka dhigan yahay 'gacanta koonfureed' sababtoo ah lafahiisa waxaa laga helay koonfurta Koonfurta Ameerika, markii horena waxaa la ogaa oo kaliya qayb ka mid ah gacanta.1

?Austrocheirus ma lahaa gacmo yaryar?

Maya. Si ka duwan qaraabadiisa abelisauroid-ka ah, Austrocheirus ma lahayn gacmo yaryar oo duuduuban. Gacmihiisu waxay ahaayeen kuwo cabbirkoodu buuxo.1 2

Daahfurka: Austrocheirus waxaa magacaabay oo sharraxay sanadkii 2010 paleontologists Martin Ezcurra, Federico Agnolin, iyo Fernando Novas. Magaca nooca isasii wuxuu sharfayaa Marcelo Pablo Isasi, oo helay oo diyaariyay lafaha.1 2
Wali waa la isku khilaafsan yahay: Saynisyahannadu ma hubo kooxda theropods ee uu Austrocheirus ka tirsan yahay. Qaar waxay yiraahdaan waa abelisauroid, kuwa kalena waxay u maleynayaan inuu yahay theropod ka sii horeeya, daraasad la sameeyay 2024 ayaana dhigtay koox cusub oo la yiraahdo Berthasauridae.1
