Ikhadi le-Dino No. 0890 kwangu-2 027

Istiodactylus

Igama lisho ukuthi: “umunwe womkhumbi”1

Udla: InyamaIzilwane ezihuquzelayo ezindizayoEarly CretaceousAkuyona i-dinosaur ngempela

Istiodactylus kwakuyisilo esindizayo esinomlomo obanzi, oyisicaba ogcwele amazinyo abukhali ahlangana ndawonye. Saphila eminyakeni eyizigidi eziyi-120 edlule futhi kungenzeka ukuthi sasebenzisa amazinyo aso njengokusika amakhukhi ukuze siphule inyama ezilwaneni ezinkulu ezifile.1 2

Iqiniso elimnandi: ama-pterosaur ayendiza phezu kwama-dinosaur, kodwa ayengozala babo, hhayi ama-dinosaur uqobo.

Ukundiza, isilinganiso

I-Istiodactylus yayidla ini?

Yayidla izilwane ezifile. Yayisebenzisa amazinyo ayo abukhali, ahlangana ndawonye njengokusika amakhukhi ukuze isike inyama ezilwaneni ezifile.

Yaphila nini?

Yayinkulu kangakanani?

Amaphiko ayo ayebanzi kangakanani?

amaphiko abanzi njengamabhayisikili angu-3 alandelanayoingandiza phezu kwenkundla yebhola yonke ngemizuzwana engu-5.5

Yayinkulu kangakanani i-Istiodactylus uma uqhathaniswa NAWE?

Izibalo nje kusiphequluli sakho. Akukho okugcinwayo noma okuthunyelwa ndawo.

Yayishesha kangakanani?

Amaqiniso amnandi

Ugebhezi lwaso lwalungamasentimitha angaba ngu-45 ubude futhi lwalunamazinyo angama-48 asondelene, amise okwesigamu sombuthano, anezinhlangothi ezintathu, ahlangana ukuze akhe umphetho obukhali njengensingo.1

Umhlathi ongezansi wawunengxenye efana nezinyo eyayilingana namazinyo angaphezulu, okwasisiza ukuba silume kahle.1

Amanye amathambo alo omhlane ayebumbene akha isakhiwo esibizwa ngokuthi i-notarium, esasisiza ukusekela amaphiko alo amakhulu.1

Imilenze yalo yangemuva yayimifushane kakhulu, kanti imilenze yangaphambili nomunwe wamaphiko kwakukukhulu, okwalenza laba uchwepheshe wokundiza.1

Isikhathi esiningi sekhulu lama-20, kwakuwukuphela kwepterosaur eyayaziwa ngamathambo alondolozwe ngendlela enezinhlangothi ezintathu, okwanika ososayensi ithuba eliyingqayizivele lokubona ukwakheka kwepterosaur.1 2

Amazinyo alo ayengafani namazinyo amade, agobile okubamba izinhlanzi kwamanye ama-pterosaur, ngakho ososayensi bacabanga ukuthi lalingazidli izinhlanzi kodwa lalidla izilwane ezifile.2

Laliphila ezindaweni ezinemifula nasogwini eningizimu yeNgilandi, lapho isimo sezulu sasifudumele, siphakathi kuka-20 no-25 °C.1

Isithombe sika-Istiodactylus 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-Istiodactylus

?Yayinkulu kangakanani i-Istiodactylus?

Ububanzi bamaphiko ayo babungamamitha angaba ngu-4.3 kuya ku-5. Ugebhezi lwayo lwalungamasentimitha angaba ngu-45 ubude.1 2

?I-Istiodactylus yayidla ini?

Yayidla izilwane ezifile. Yayisebenzisa amazinyo ayo abukhali, ahlangana ndawonye njengokusika amakhukhi ukuze isike inyama ezilwaneni ezifile.1 2

?Ingabe i-Istiodactylus kwakuyidinosaur?

Cha, kwakuyipterosaur, isilwane esindizayo esaphila ngesikhathi esifanayo nama-dinosaur kodwa akuyona idinosaur.1

?Ingabe i-Istiodactylus yayikwazi ukundiza?

Yebo, kwakuyisilwane esindizayo esinamaphiko amakhulu. Kungenzeka ukuthi yayinguchwepheshe wokundiza, ishelela amabanga amade ukuze ithole ukudla.1

Umchithi wezinganekwane

Inganekwane: Abanye abantu bacabanga ukuthi i-Istiodactylus kwakuyidinosaur ngoba yayiphila nama-dinosaur futhi inamazinyo abukhali.

Iqiniso: I-Istiodactylus kwakuyipterosaur, isilwane esindizayo, hhayi idinosaur. Ama-pterosaur ayiqembu elihlukile lezilwane ezihuquzelayo.1

Ochwepheshe bama-dino

Igama lesayensi: Istiodactylus
Iqanjwe ngu: Howse et al. 20013
Iqembu: Izilwane ezihuquzelayo ezindizayo
Umndeni / i-clade: Ornithocheiroidea3
Ukuhlukaniswa: Pterosauria > Pterodactyloidea3

Amazwe: United Kingdom, I-China3
Izinsalela ezitholiwe: 6 ku-Paleobiology Database3
Ukutholakala: Isithombe sokuqala sethambo satholakala e-Isle of Wight ngo-1887, kwathi ngo-1901 saqanjwa ngokuthi Ornithodesmus latidens. Ngo-2001, ososayensi basibeka ohlotsheni lwaso, i-Istiodactylus.1
Kusaphikiswana ngakho: Ososayensi bayaphikisana ngokuthi ingabe uhlobo lwaseChina i-Istiodactylus sinensis luyingxenye yalesi sigaba ngempela noma luhlukile, nokuthi ingabe lufana yini nenye i-pterosaur ebizwa ngokuthi i-Longchengpterus.1
