Piscivorenantiornis

Igama lisho ukuthi: “inyoni edla izinhlanzi yohlobo lwe-enantiornithine”1

Udla: IzinhlanziIzinyoni zakuqalaEarly Cretaceous

I-Piscivorenantiornis yayiyinyoni encane kakhulu eyayiphila e-China eminyakeni eyizigidi ezingu-120 edlule. Yayithanda ukudla izinhlanzi futhi yayikwazi nokukhipha amathambo ezinhlanzi ngomlomo, njengoba ezinye izinyoni zenza namuhla!1 2

Amaqiniso amnandi

Yinyoni yokuqala eyaziwayo yohlobo lwe-enantiornithine edla izinhlanzi.1

Izinsalela zokuqala zatholakala nenqwaba yamathambo ezinhlanzi esiswini sayo, okungenzeka ukuthi kwakuyinto eyayisizokhipha ngomlomo.1

I-pelvis yayo (amathambo ezinqulu) yayihlangene ngokuphelele, okuyinto engavamile ezinyonini zesikhathi sokuqala se-Cretaceous. Izinyoni ezimbalwa kuphela zohlobo lwe-enantiornithine ezabelana ngalesi sici.2

I-sternum (ithambo lesifuba) yayinamazinyo akhethekile ngaphambili okungezona ezinye izinyoni zohlobo lwe-enantiornithine ezinayo.1

Elilodwa lamathambo entamo lalinomumo ongaqondakali: laligobile phezulu naphansi ohlangothini olulodwa, nangakwesobunxele nangakwesokudla kolunye. Ayikho enye inyoni enalokho.3

Isidumbu sesibili sale nyoni satholakala ngo-2020, sanika ososayensi izinkomba eziningi mayelana nendlela eyayiphila ngayo.1

Yaphila ngesikhathi se-Aptian, eminyakeni eyizigidi ezingu-121 kuya kwangu-113 edlule.4

Isithombe sika-Piscivorenantiornis 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.

Ochwepheshe bama-dino

Igama lesayensi: Piscivorenantiornis
Iqanjwe ngu: Wang and Zhou 20174
Iqembu: Izinyoni zakuqala
Umndeni / i-clade: Enantiornithes4
Ukuhlukaniswa: Theropoda > Avialae4
Inkathi yamadwala: 121 kuya ku-113 wezigidi zeminyaka (Aptian)4
Izakhiwo zamatshe: Jiufotang4
Amazwe: I-China4
Izinsalela ezitholiwe: 1 ku-Paleobiology Database4
Ukutholakala: Izinsalela zokuqala zatholakala eduze kwase-Dapingfang e-Liaoning, e-China. Yaqanjwa ngokuthi i-Piscivorenantiornis inusitatus ngu-Wang, Zhou no-Sullivan ngo-2016.1
Kusaphikiswana ngakho: Ososayensi basazibuza ukuthi kungani ithambo lentamo linomumo ongaqondakali kangaka, ngokungafani nanoma iyiphi enye inyoni.3
