Mengciusornis

Igama lisho ukuthi: “Inyoni ka-Mencius”1

Udla: InyamaIzinyoni zakuqalaEarly Cretaceous

I-Mengciusornis yayiyinyoni yakuqala eyayiphila e-China ngesikhathi samadinosaur. Yayine amazinyo abukhali, ajikile emhlathini wayo ongaphezulu, kodwa okunye komlomo wayo kwakungenamazinyo. Lesi silwane esincane sasikwazi ukundiza futhi mhlawumbe sasizingela izinambuzane nezilwane ezincane.1 2

Amaqiniso amnandi

I-Mengciusornis yayinamazinyo kuphela engxenyeni engaphambili yomhlathi wayo ongaphezulu, obizwa ngokuthi i-premaxilla. Isihlobo sayo esiseduze i-Schizooura sasingenawo amazinyo nhlobo.1 2

Isitho esisodwa esaziwayo se-Mengciusornis isidumbu esilondolozwe kahle esibonisa ngisho nezinsalela zezimpaphe.1

I-Mengciusornis yaphila eminyakeni engaba yizigidi eziyi-121 kuya kweziyi-113 edlule, phakathi nenkathi ye-Early Cretaceous.3

Igama layo lihlonipha isazi sefilosofi sase-China sasendulo u-Mencius, kanti 'dentatus' kusho 'enamazinyo' ngesi-Latin.1

I-Mengciusornis yayinethambo lomkhono elimise okwe-V (furcula) kanye nomqhele omkhulu onxande ethanjeni layo eliphezulu lomkhono.2

Ososayensi bacabanga ukuthi ukulahleka kwamazinyo ezinyoni zakudala kwenzeka ngezindlela ezahlukene emaqenjini ahlukene. I-Mengciusornis ikhombisa indlela eyingqayizivele lapho ingaphambili lomhlathi ongaphezulu ligcine amazinyo kanti okunye komlomo kwawalahlekelwa.2

Isithombe sika-Mengciusornis esenziwe nge-AI sokuthi kungenzeka ukuthi wayebukeka kanjani, senziwe yikhompyutha ngokusekelwe kulokho okwaziwa ososayensi. Lokhu kuwukuqagela: isilwane sangempela kungenzeka ukuthi sasibukeka ngokuhlukile, futhi akekho owazi imibala yaso yangempela.

Ukutholakala: I-Mengciusornis yaqanjwa ngo-2019 ngu-Wang nozakwabo ngokusekelwe ethanjeni elilodwa (IVPP V26275) elivela e-Jiufotang Formation e-China.1 3
Kusaphikiswana ngakho: Ososayensi basaphikisana ngokuthi i-Mengciusornis ihlobene kanjani nezinye izinyoni zakuqala nokuthi ukulahleka kwamazinyo kwavela kanjani ohlotsheni lwayo.2
