Palaeocursornis

Magacu wuxuu ka dhigan yahay: “shimbir duug ah oo orda”2

Cunay: KalluunXayawaanka duulaCretaceous-kii horeSi farsamo ahaan ma aha dinosaur

Palaeocursornis wuxuu ahaa xamaarato duusha oo yar, ee ma ahayn dinosaur. Wuxuu noolaa xilligii Early Cretaceous, qiyaastii 143 ilaa 137 milyan oo sano ka hor. Fosilladiisa waxaa laga helay Romania, macdan qoditaan mar ahaan jirtay nidaam godad ah.2

Xaqiiqo xiiso leh: pterosaurs waxay ku duuleen dinos-ka dushooda, laakiin waxay ahaayeen ilma-adeerkood, ma ahayn dinos laftoodu.

Xaqiiqooyin xiiso leh

Palaeocursornis waxaa markii hore loo malaynayay inuu yahay shimbir, laakiin saynisyahannadii dambe ayaa go'aamiyay inuu yahay pterosaur, xamaarato duusha.2 1

Magaciisu wuxuu ka dhigan yahay 'shimbir duug ah oo orda', inkastoo uusan ahayn shimbir oo uusan ahayn mid orda. Taa beddelkeeda wuu duuli jiray.2

Fossil-ka kaliya ee la yaqaan ee Palaeocursornis waa qayb ka mid ah laf-bowdada (femur). Taasi waxay ka dhigaysaa mid aad u adag in la ogaado sida uu u ekaa.2 1

Saynisyahannada qaarkood waxay u malaynayaan in Palaeocursornis laga yaabo inuusan ahayn nooc sax ah gabi ahaanba. Waxay ugu yeeraan nomen dubium, taas oo macnaheedu yahay 'magac shaki leh'.2 1

Fossil-ka waxaa laga helay macdan bauxite ah oo ku taal Romania, gudaha dhagax mar ahaan jirtay qayb ka mid ah nidaam godad duug ah.1

Dhagaxa hayay Palaeocursornis wuxuu u dhexeeyaa 143.1 iyo 137.05 milyan oo sano, laga soo bilaabo heerka Berriasian ee Early Cretaceous.2

Sawirka Palaeocursornis oo uu sameeyay AI — Sawir uu sameeyay AI oo muujinaya sida Palaeocursornis 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.

Burinta khuraafaadka

Khuraafaad: Palaeocursornis wuxuu ahaa shimbir duug ah.

Runta: In kasta oo magaciisu macnihiisu yahay 'shimbir duug ah oo orda', Palaeocursornis hadda waxaa loo kala saaraa pterosaur, xamaarato duusha, ee ma aha shimbir.2 1

Khubarada dino

Magaca sayniska: Palaeocursornis
Waxaa magacaabay: Kessler and Jurcsák 19862
Koox: Xayawaanka duula
Qoyska / kooxda: Pterosauria2
Kala soocidda: Pterosauria2
Xilligii dhagaxyada: 143 ilaa 137 milyan oo sano (Berriasian)2
Dhagaxyada: Lower Bauxite2
Waddamada: Romania2
Diiwaanka fossil-ka: 1 oo ku jira Paleobiology Database2
Daahfurka: Palaeocursornis waxaa magacaabay Kessler iyo Jurcsák 1986, iyagoo ku salaynaya hal laf-bowdo oo laga helay macdanta bauxite ee Cornet ee Romania.2
Wali waa la isku khilaafsan yahay: Saynisyahannadu ma hubo in Palaeocursornis uu yahay nooc sax ah. Qaar baa u malaynaya in hal laf oo fossil ah aysan ku filnayn in lagu kala saaro pterosaurs kale.2 1
