Protoichthyosaurus

Magacu wuxuu ka dhigan yahay: “xamaarato kalluunka ugu horreeya”1

Cunay: HilibIchthyosaursJurassic-kii horeSi farsamo ahaan ma aha dinosaur

Protoichthyosaurus wuxuu ahaa xamaarato badeed oo hore, wuxuuna u ekaa dolphin leh san dheer iyo baalal. Wuxuu ku dabaalan jiray badaha diirran ee gacanka yar ee daboolay qaybo ka mid ah England xilligii Early Jurassic, qiyaastii 200 milyan oo sano ka hor.1

Xaqiiqo xiiso leh: xayawaankan badda ku nool wuxuu dabaalanayay halka dinos-ku ay dhulka ku socdeen. Qof walba wuxuu ugu yeeraa dinos, laakiin waxay ahaayeen qayb kale oo ka mid ah xayawaanka gurguurta.

Ilkihiisu waxay lahaayeen jeexdin qoto dheer oo si adag ugu xididaysan, taas oo soo jeedinaysa inuu cuni jiray kalluunka iyo xayawaannada kale ee yaryar ee badda, laakiin ilaha macluumaadku ma sheegaan cunto gaar ah.

Xaqiiqooyin xiiso leh

Protoichthyosaurus waxaa markii ugu horreysay magacaabay Robert M. Appleby sanadkii 1979, laakiin muddo ayay saynisyahannadu u haysteen inuu yahay nooc ka mid ah Ichthyosaurus. Sanadkii 2017, daraasad cusub ayaa muujisay inuu yahay nooc gaar ah.1

Waxaa jira laba nooc: P. prostaxalis, oo gaari karay ilaa 4 m oo dherer ah, iyo P. applebyi oo ka yar, kaas oo ugu badnaan ahaa 2 m.1

Baalashiisu waxay lahaayeen qaab gaar ah oo lafaha curcurka ah oo ka caawiyay saynisyahannada inay ka soocaan ichthyosaurs-ka kale.1

Protoichthyosaurus wuxuu lahaa laf saddex-xagal ah oo weyn oo ku taal daanka sare (maxilla) taas oo ka soo baxday lafaha sanka, taas oo ah muuqaal gaar ah.1

Qaar badan oo ka mid ah lafaha ayaa ka yimid ururinta Charles Moore, taas oo mararka qaarkood isku qasta lafaha xayawaanno kala duwan, taas oo ku adkaysay saynisyahannada.1

Ilkihiisu waxay lahaayeen jeexdin qoto dheer oo hoos ugu dhacda xididdada, waxayna si adag ugu xirnaayeen daanka.1

Sawirka Protoichthyosaurus oo uu sameeyay AI — Sawir uu sameeyay AI oo muujinaya sida Protoichthyosaurus u ekaan karay, oo uu kombuyuutarku ka sameeyay waxa ay saynisyahannadu yaqaaniin. Waa qiyaas: xayawaanka dhabta ah waxaa laga yaabaa inuu u ekaa si ka duwan, qofna ma garanayo midabadiisa dhabta ah.

Su'aalaha ugu badan ee ku saabsan Protoichthyosaurus

?Protoichthyosaurus ma ahaa dinosaur?

Maya, wuxuu ahaa ichthyosaur, xamaarato badeed ku noolaa badda. Ichthyosaurs ma aha dinosaurs.1

?Intee in le'eg ayuu ahaa Protoichthyosaurus?

Wuxuu ahaa mid dhexdhexaad ah. P. prostaxalis wuxuu gaaray ilaa 4 m (13 ft) dherer ah, halka P. applebyi uu ka yaraa, ugu badnaan 2 m (6.6 ft).1

?Maxuu cuni jiray Protoichthyosaurus?

?Xaggee ayuu ku noolaa Protoichthyosaurus?

Wuxuu ku noolaa badaha Early Jurassic ee koonfurta England iyo suurtagal ahaan Switzerland. Lafaha waxaa laga helay Somerset, Dorset, iyo qaybo kale oo ka mid ah UK.1 3

Burinta khuraafaadka

Khuraafaad: Protoichthyosaurus waa dinosaur.

Runta: Ma aha dinosaur. Waa ichthyosaur, oo ah koox xamaarato badeed ah oo ku noolaa badda isla xilligii ay noolaayeen dinosaurs-ka.1

Khubarada dino

Magaca sayniska: Protoichthyosaurus
Waxaa magacaabay: Appleby 19794
Koox: Ichthyosaurs
Qoyska / kooxda: Ichthyosauridae4
Kala soocidda: Ichthyosauria > Ichthyosauromorpha4
Xilligii dhagaxyada: 201 ilaa 184 milyan oo sano (Hettangian / Pliensbachian)4
Dhagaxyada: Blue Lias4
Waddamada: Boqortooyada Midowday4
Diiwaanka fossil-ka: 2 oo ku jira Paleobiology Database4
Daahfurka: Robert M. Appleby ayaa u bixiyay magaca Protoichthyosaurus sanadkii 1979 isagoo ku salaynaya lafo laga helay Street, Somerset, England. Muunadda ugu weyn (BRLSI M3553) waa qayb ka mid ah lafaha.1 2
Wali waa la isku khilaafsan yahay: Saynisyahannadu ma hubo in nooc saddexaad, P. fortimanus, uu yahay nooc gaar ah ama uu yahay magac kale oo loo bixiyay mid ka mid ah labada kale.1
