Ikhadi le-Dino No. 2014 kwangu-2 027

Zhongjianornis

Igama lisho ukuthi: “Inyoni ka-Zhongjian, eqanjwe ngomsunguli we-Institute of Vertebrate Paleontology and Paleoanthropology, u-Yang Zhongjian”1

Udla: InyamaIzinyoni zakuqalaEarly Cretaceous

Zhongjianornis kwakuyinyoni engangejuba eyayiphila e-China ngesikhathi se-Early Cretaceous, eminyakeni engaba ngu-120 yezigidi edlule. Yayinomlomo ongenamazinyo nemisipha yamaphiko enamandla, okwayenza yakwazi ukundiza kahle. Le nyoni encane isiza ososayensi ukuba baqonde ukuthi izinyoni zokuqala zavela kanjani futhi zalahlekelwa kanjani amazinyo azo.1 2

Ukundiza, isilinganiso

Wayedlani u-Zhongjianornis?

Ososayensi abaqiniseki, kodwa umlomo wayo ongenamazinyo uphakamisa ukuthi kungenzeka ukuthi yayidla imbewu noma izinambuzane ezincane.

Yayinkulu kangakanani i-Zhongjianornis uma uqhathaniswa NAWE?

Izibalo nje kusiphequluli sakho. Akukho okugcinwayo noma okuthunyelwa ndawo.

izinto ezinhle

Amaqiniso amnandi

Zhongjianornis ingenye yezinyoni zakudala kakhulu ezaziwa ngokulahlekelwa amazinyo azo ngokuphelele, esikhundleni sawo yaba nomlomo.2

Ithambo layo elikhulu (humerus) lalinomgogodla oqinile, owawubanzi njengethambo uqobo futhi ungaphezu kwengxenye yesithathu yobude bethambo lonke, okukhombisa ukuthi yayinemisipha enamandla yokundiza.3

Izinsalela kuphela ezaziwayo zika-Zhongjianornis yisidumbu esicishe saphelela esinezimpawu ezithile zezimpaphe ezingalondolozwanga kahle.3

Zhongjianornis yaphila ngesikhathi se-Aptian esikhathini se-Early Cretaceous, eminyakeni engaba ngu-121 kuya kwengu-113 yezigidi edlule.3

Ososayensi ekuqaleni babecabanga ukuthi u-Zhongjianornis wayeyinyoni yakudala kakhulu, kodwa ucwaningo olwalandela ngo-2012 lwaphakamisa ukuthi yayifana kakhulu nezinyoni ezithuthukile zohlobo lwe-euornithean ezifana ne-Chaoyangia.1

Igama lohlobo oluthi yangi lihlonipha u-Yang Zhongjian, umsunguli we-Institute of Vertebrate Paleontology and Paleoanthropology e-Beijing.1

Isithombe sika-Zhongjianornis 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.

ubuzile

Imibuzo ebuzwa kakhulu mayelana no-Zhongjianornis

?Wayemkhulu kangakanani u-Zhongjianornis?

Wayengangejuba. Kwakuyinyoni encane.1

?Ingabe u-Zhongjianornis wayenamazinyo?

Cha, wayenomlomo ongenamazinyo. Ingenye yezinyoni zakudala kakhulu ezaziwa ngokulahlekelwa amazinyo azo ngokuphelele.1 2

?Wayedlani u-Zhongjianornis?

Ososayensi abaqiniseki, kodwa umlomo wayo ongenamazinyo uphakamisa ukuthi kungenzeka ukuthi yayidla imbewu noma izinambuzane ezincane.1

Umchithi wezinganekwane

Inganekwane: Zhongjianornis kwakuyinyoni yakudala kakhulu engenamazinyo.

Iqiniso: Nakuba ekuqaleni kwakucatshangwa ukuthi iyinyoni yakudala kakhulu, ukuhlaziya okwenziwa ngo-2012 kwakhombisa ukuthi u-Zhongjianornis uhlobene kakhulu nezinyoni ezithuthukile zohlobo lwe-euornithean, hhayi eyakudala kakhulu.1

Ochwepheshe bama-dino

Igama lesayensi: Zhongjianornis
Iqanjwe ngu: Zhou et al. 20104
Iqembu: Izinyoni zakuqala
Umndeni / i-clade: Ornithuromorpha4
Ukuhlukaniswa: Theropoda > Avialae4

Amazwe: I-China4
Izinsalela ezitholiwe: 1 ku-Paleobiology Database4
Ukutholakala: Zhongjianornis yaqanjwa futhi yachazwa ngu-Zhou, Zhang, no-Li ephepheni elashicilelwa ngo-Januwari 2010 (nakuba yavela ku-inthanethi ngo-2009). Izinsalela kuphela, okuyisidumbu esicishe saphelela, zatholakala e-Jianchang esifundazweni sase-Liaoning, e-China.1 2
Kusaphikiswana ngakho: Ososayensi basaphikisana ngokuthi u-Zhongjianornis wayeyinyoni yakudala kakhulu noma eyayithuthuke kakhulu yohlobo lwe-euornithean, ngenxa yokuhumusha okungafani kwesakhiwo sezinsalela zayo.1

Yonke imininingwane ekuleli khasi inenombolo ekhomba umthombo wayo. Uma kukhona esikwenze kabi, siyaxolisa, singabalandeli bama-dino, hhayi iphephabhuku lesayensi. Sitshele ku-[email protected] futhi sizokulungisa.
