Maiaspondylus

Magacu wuxuu ka dhigan yahay: “laf-dhabarta hooyada daryeesha”1
Cunay: HilibIchthyosaursCretaceous-kii horeSi farsamo ahaan ma aha dinosaur

Maiaspondylus wuxuu ahaa xamaarato badda ku nool oo ku noolaa badda, ee ma ahayn dinosaur. Wuxuu ahaa ichthyosaur, oo ah ugaarsade si degdeg ah u dabaasha oo leh san dheer iyo ilko fiiqan. Fossilladu waxay muujinayaan inuu dhalay dhallaan nool, sida ay maanta sameeyaan nibiriyada iyo dolphins-ka.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.

Xaqiiqooyin xiiso leh

1

Maiaspondylus macnaheedu waa 'laf-dhabarta hooyada daryeesha' sababtoo ah fossil ayaa la helay iyadoo laba uurjiif ay ku jiraan gudaha xayawaan weyn, taas oo muujinaysa inuu dhalay dhallaan nool.1

2

Uurjiifka laga helay gudaha qofka weyn waa uurjiifka ichthyosaur ee ugu yar uguna da'da yar ee abid la helo.1

3

Maiaspondylus wuxuu noolaa qiyaastii 110 milyan oo sano ka hor intii lagu jiray xilligii Early Cretaceous.1

4

Fossilladiisa waxaa markii ugu horreysay laga helay Loon River Formation ee Canada's Northwest Territories.1

5

Maiaspondylus wuxuu lahaa habayn laf madax oo gaar ah: jugal iyo maxilla ayaa is dul saarnaa wax badan, taas oo ka caawisay saynisyahannada inay ka soocaan ichthyosaurs-ka kale.2

6

Ilkihiisu waxay lahaayeen taajaj siman iyo cementum fluted (daboolka xididka), waxayna u qaloocdeen gudaha dhanka carrabka.2

7

Lafta gacanta (humerus) ee Maiaspondylus waxay lahayd saddex buro oo dhamaadka ah muruqyada, iyadoo burada dhexe ay ka yar tahay kuwa dibadda.2

Sawir uu sameeyay AI oo muujinaya sida Maiaspondylus 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 Maiaspondylus

?Intee ayuu la ekaa Maiaspondylus?

Qofna si hubaal ah uma oga sababtoo ah lama helin laf-dhabar dhammaystiran. Fossillada la yaqaan waxaa ka mid ah laf-dhabar ku dhowaad dhammaystiran iyo laf-dhabar ka yimid xayawaan waaweyn, laakiin saynisyahannadu ma qiyaasin dhererkiisa guud.1

?Maiaspondylus ma dhalay dhallaan nool?

Haa. Fossil ka mid ah Maiaspondylus weyn ayaa la helay iyadoo laba uurjiif ay ku jiraan gudaha, taas oo caddaynaysa inuu dhalay dhallaan nool, sida nibiriyada iyo dolphins-ka.13

?Xagee laga helay Maiaspondylus?

Fossilladiisa waxaa markii ugu horreysay laga helay Loon River Formation ee Canada's Northwest Territories. Mar dambe, fossillada waxaa sidoo kale laga helay England iyo Russia.1

Wali waa la isku khilaafsan yahay
Saynisyahannadu weli waxay ku doodayaan sida saxda ah ee Maiaspondylus uu ula xiriiro ichthyosaurs-ka kale, gaar ahaan genus-ka Platypterygius.1
