Protoichthyosaurus

Igama lisho ukuthi: “isilwane esifana nenhlanzi sokuqala”1

Udla: InyamaAma-ichthyosaurEarly JurassicAkuyona i-dinosaur ngempela

I-Protoichthyosaurus kwakuyisilwane sasolwandle sasendulo esasinjengodolphin esinomlomo omude namaphiko okubhukuda. Sasibhukuda ezilwandle ezifudumele nezingashoni ezazimboze izingxenye ze-England ngesikhathi se-Early Jurassic, eminyakeni engaba ngu-200 million edlule.1

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

I-Protoichthyosaurus yayidla ini?

Amazinyo ayo ayenemisele ejulile futhi ayebambeke ngokuqinile, okusikisela ukuthi yayidla izinhlanzi nezinye izilwane ezincane zasolwandle, kodwa imithombo ayisho ukuthi yayidla ini ngokuqondile.

Amaqiniso amnandi

I-Protoichthyosaurus yaqanjwa okokuqala ngo-1979 ngu-Robert M. Appleby, kodwa isikhathi esithile ososayensi babecabanga ukuthi iwuhlobo lwe-Ichthyosaurus. Ngo-2017, ucwaningo olusha lwabonisa ukuthi iwuhlobo olwehlukile.1

Kunezinhlobo ezimbili: i-P. prostaxalis, eyayikwazi ukufika ku-4 m ubude, kanye ne-P. applebyi encane, eyayiba ngu-2 m ubude kakhulu.1

Amaphiko ayo ayenendlela ekhethekile yamathambo esihlakala eyasiza ososayensi ukuba ayihlukanise nezinye izi-ichthyosaur.1

I-Protoichthyosaurus yayinethambo elikhulu elingunxantathu emhlathini wayo ongaphezulu (i-maxilla) elaliphuma kakhulu kunamathambo ayo ekhala, okuyisici esiyingqayizivele.1

Izinsalela eziningi zivela eqoqweni lika-Charles Moore, elalivame ukuxuba amathambo ezilwane ezahlukene, okwenza kube nzima kososayensi.1

Amazinyo ayo ayenemisele ejulile eyayihla iye ezimpandeni, futhi ayebambeke ngokuqinile emhlathini.1

Isithombe sika-Protoichthyosaurus 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.

Imibuzo ebuzwa kakhulu mayelana no-Protoichthyosaurus

?Ingabe i-Protoichthyosaurus yayiyidinosaur?

Cha, kwakuyi-ichthyosaur, isilwane sasolwandle esasiyisidalwa sasolwandle. Ama-ichthyosaur awawona ama-dinosaur.1

?Yayinkulu kangakanani i-Protoichthyosaurus?

Yayinosayizi ophakathi. I-P. prostaxalis yayifinyelela kumamitha angu-4 (13 ft) ubude, kanti i-P. applebyi yayincane, ibe ngamamitha angu-2 (6.6 ft) ubude kakhulu.1

?I-Protoichthyosaurus yayidla ini?

Amazinyo ayo ayenemisele ejulile futhi ayebambeke ngokuqinile, okusikisela ukuthi yayidla izinhlanzi nezinye izilwane ezincane zasolwandle, kodwa imithombo ayisho ukuthi yayidla ini ngokuqondile.1

?I-Protoichthyosaurus yayihlala kuphi?

Yayihlala ezilwandle ze-Early Jurassic eningizimu ye-England futhi mhlawumbe naseSwitzerland. Izinsalela zitholakale eSomerset, eDorset, nakwezinye izingxenye ze-UK.1 3

Buza u-Rex ngo-Protoichthyosaurus

Rex uphendula imibuzo mayelana naleli khasi kuphela. Imibuzo engu-10 ngenyanga.

Rex uyi-AI futhi angenza amaphutha. Usebenza kumaseva ase-EU futhi imibuzo ayilokothi ilondolozwe. Ungalokothi uthayiphe igama lakho noma ezinye izinto zakho.

Umchithi wezinganekwane

Inganekwane: I-Protoichthyosaurus iyidinosaur.

Iqiniso: Akuyona idinosaur. Kuyi-ichthyosaur, iqembu lezilwane zasolwandle ezazihlala olwandle ngesikhathi esifanayo nama-dinosaur.1

Ochwepheshe bama-dino

Igama lesayensi: Protoichthyosaurus
Iqanjwe ngu: Appleby 19794
Iqembu: Ama-ichthyosaur
Umndeni / i-clade: Ichthyosauridae4
Ukuhlukaniswa: Ichthyosauria > Ichthyosauromorpha4
Inkathi yamadwala: 201 kuya ku-184 wezigidi zeminyaka (Hettangian / Pliensbachian)4
Izakhiwo zamatshe: Blue Lias4
Amazwe: United Kingdom4
Izinsalela ezitholiwe: 2 ku-Paleobiology Database4
Ukutholakala: U-Robert M. Appleby waqamba i-Protoichthyosaurus ngo-1979 ngokusekelwe ezinsaleleni ezatholakala eStreet, eSomerset, e-England. Isampula eliyinhloko (BRLSI M3553) liyingxenye yethambo.1 2
Kusaphikiswana ngakho: Ososayensi abaqiniseki ukuthi uhlobo lwesithathu, i-P. fortimanus, luhlobo olwehlukile ngempela noma luyigama nje elinye lezinye izinhlobo ezimbili.1
