Ikhadi le-Dino No. 0012 kwangu-2 027

Acamptonectes

Igama lisho ukuthi: “umshayi-manzi oqinile”1

Udla: InyamaAma-ichthyosaurEarly CretaceousAkuyona i-dinosaur ngempela

I-Acamptonectes yayiyisilwane sasolwandle esishaya amanzi ngokushesha esayiphila ezilwandle ze-Early Cretaceous. Yayinomzimba oqinile namehlo amakhulu, alungele ukuzingela izinhlanzi nezilwane ezibizwa nge-squid olwandle olujulile.1 2

Iqiniso elimnandi: lesi silwane sasolwandle sasibhukuda ngenkathi ama-dinosaur ehamba emhlabathini. Wonke umuntu ubabiza ngama-dino, kodwa ayeyigatsha elihlukile lezilwane ezihuquzelayo.

Amaqiniso amnandi

I-Acamptonectes ingeyeqembu elibizwa ngama-ophthalmosaurid, elalinamehlo amakhulu kakhulu okubona emanzini amnyama, ajulile.1 2

Igama layo lisho 'umshayi-manzi oqinile' ngoba umzimba wayo wawuqinile ngokungajwayelekile, okuyisiza ukuba ihambe ngokushesha emanzini.1

I-Acamptonectes yaphila cishe eminyakeni eyizigidi eziyi-133 kuya kweziyi-129 edlule, phakathi nesigaba se-Hauterivian se-Early Cretaceous.1

Ososayensi bake bacabanga ukuthi iningi lama-ichthyosaur lashabalala ekupheleni kwe-Jurassic, kodwa i-Acamptonectes ikhombisa ukuthi asinda futhi aphumelela kwaze kwaba se-Cretaceous.2 1

Insali yokuqala ye-Acamptonectes yatholakala ngonyaka we-1958 ngabafundi be-geology eduze kwase-Speeton, e-England, kodwa ayizange iqanjwe kwaze kwaba ngonyaka we-2012.2 1

Amazinyo ayo ayenemigqa emincane emide, eyayiyisiza ukuba ibambe izilwane ezishelelayo ezifana nezinhlanzi ne-squid.1

Isithombe sika-Acamptonectes 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-Acamptonectes

?Ingabe i-Acamptonectes yayiyi-dinosaur?

Cha, yayiyisilwane sasolwandle esibizwa nge-ichthyosaur, hhayi i-dinosaur.1

?Yayinkulu kangakanani i-Acamptonectes?

Yayicishe ibe ngamamitha ayi-3 (izinyawo eziyi-9.8) ubude.1

?I-Acamptonectes yayidla ini?

Kungenzeka yayidla izilwane ezithambile ezifana nezinhlanzi ne-squid, isebenzisa amazinyo ayo amancane anemicu ukuzibamba.1

?Kungani i-Acamptonectes yayinomzimba oqinile?

Umzimba wayo oqinile wayisiza ukuba ishaye amanzi ngokushesha njenge-tuna ngokuyenza ibe lula ukuhamba emanzini.1

Umchithi wezinganekwane

Inganekwane: Abantu abaningi bacabanga ukuthi wonke ama-ichthyosaur ashabalala ekupheleni kwe-Jurassic.

Iqiniso: I-Acamptonectes namanye ama-ophthalmosaurid aphila kwaze kwaba se-Cretaceous, okubonisa ukuthi akuzange kube nokushabalala okukhulu ngaleso sikhathi.2 1

Ochwepheshe bama-dino

Igama lesayensi: Acamptonectes
Iqanjwe ngu: Fischer et al. 20123
Iqembu: Ama-ichthyosaur
Umndeni / i-clade: Ophthalmosauridae3
Ukuhlukaniswa: Ichthyosauria > Ichthyosauromorpha3
Inkathi yamadwala: 133 kuya ku-126 wezigidi zeminyaka (Hauterivian)3
Izakhiwo zamatshe: Speeton Clay3
Amazwe: United Kingdom, Germany3
Izinsalela ezitholiwe: 3 ku-Paleobiology Database3
Ukutholakala: I-Acamptonectes yaqanjwa ngonyaka we-2012 yiqembu lososayensi okubalwa kubo u-V. Fischer, u-M. W. Maisch, kanye no-D. Naish. Isampula yokuqala yaqoqwa ngonyaka we-1958 ngabafundi be-geology e-Speeton, e-England, kodwa kwathatha amashumi eminyaka ukuyifunda nokuyichaza.2 3
Kusaphikiswana ngakho: Ososayensi basaphikisana ngokuthi i-Acamptonectes yayinokudla okuhlukile noma indlela yokuphila ehlukile kunamanye ama-ichthyosaur e-Cretaceous ngenxa yomlomo wayo ongajwayelekile kanye nokuma kwamazinyo.1
