Ithiyori entsha izama ukucacisa ukuba kutheni iidinosaurs zikhule kakhulu - ngakumbi iinecks zazo ezimangalisayo

Iipaleontologists zilwa neemfihlelo ezininzi kwicandelo labo lokufunda, hayi elona lincinci lelona livumela ezinye iidinosaurs ukuba zibe nkulu ngokungazithembi. Ngokukodwa, iintamo ezinkulu ze-sauropods ezifana ne-brachiosaurus, i-diplodocus, okanye i-sauroposeidon (ende kunazo zonke iidinosaurs, ukuphakama kweenyawo ezingama-56) ziye zaphazamisa ixesha elide. Oososayensi bacebisa ukuba iimpawu zokuphefumla ezizodwa kunye neendlela zokuphinda zivelise kwakhona zivunyelwe kubungakanani obukhulu kunye neentamo ezingalinganiyo nasiphi na isidalwa okoko.

Ukucaciswa malunga nokuba iidinosaurs zikufumene njani ukukhula kwazo zininzi, kwaye ezinye zazo zibonisa imeko yokusingqongileyo njengamanqanaba aphezulu eoksijini okanye ukutya okugqithisileyo. Ngokumangalisayo, ilivo le-baseball kunye ne-non-paleontologist eyaziwayo UJose Canseco Kutshanje kubhalwe ukuba uMhlaba unokuba nomxhuzulane ophantsi kwiintsuku zakudala, kwaye oko kungachaza izilwanyana ezikhulu ezazisetyenziswa kukuziqhayisa. Le ayisiyongcamango eyonwabisayo kuphela, kodwa sisikhumbuzo esikhulu sokuba kutheni singazifumani iinyani zethu zesayensi kubaxhaphazi be-steroid kwimidiya yoluntu.

Umbhali weSayensi UBrian Switek iazise ithiyori entsha, nangona kunjalo, icaphula kwizifundo zeengcali ze-sauropod UMichael Taylor kwaye UMathew Wedel . Imeko yendalo esingqongileyo inokuba yeyokwenyani, ukuba akunakulindeleka (ngaphandle kwento yomxhuzulane, ebubudenge nje), kodwa ngekhe isebenze njengezinto ezikhuthazayo ekungakhawuleni kokukhula kwee-sauropods. Endaweni yoko, ii-sauropods zazinothungelwano lweesaka zomoya kwiinkqubo zazo zokuphefumla ezenza amathambo abo, afana nalawo eentaka, alula ngakumbi ngaphandle kokuncama amandla. Ngamathambo akhaphukhaphu, iintamo zazo zazinokukhula zide ngokungaqhelekanga - kwezinye iimeko phantse isiqingatha sobude bomzimba wedayinaso.

Iintloko zabo zazincinci, nazo, kungekho sidingo semisipha efunekayo ukuhlafuna umba wezityalo abazidlileyo; bona khange ukuhlafuna, kwaye okwangoku akukaziwa ukuba bakwenza njani ukutya okuninzi ngaphandle kwejusi. Ngayiphi na imeko, ii-sauropods zazinomzimba opheleleyo ukuxhasa ezo ntamo zide kunye neentloko ezincinci, zolule ngokulinganayo indlulamthi.

Ezi ziintamo ze-non-sauropods, ezingakonwabeliyo ubunewunewu beentamo ezinde kakhulu. Kwakhona, ayisiyondawo ilungileyo yokuba umntu eme ngaphandle kobuso bakhe.

Emva koko kukho into yokuba ii-sauropods zazizirhubuluzi. I-sauropods ezincinci zazincinci - kwaye zinokuthandeka- kwaye zinokuba zininzi. Apho izilwanyana ezanyisayo zichitha ixesha elininzi kunye namandla okuphatha nokukhulisa amantshontsho azo, iidinos ziya kuthi zenze abantwana bazo ngobuninzi kwiindawo zokuzalisa ezinkulu.

UBrian Switek ucacisa kwi-National Geographic :

Ngokukhuphela ngaphandle ukuzalwa kunye nophuhliso, ii-sauropods kunye nezinye iidinosaurs zikwazile ukuthintela iindleko kunye nomngcipheko othintela ubungakanani bezilwanyana ezanyisayo. Kwiidinosaurs, oomatshini kunye nezinye izithintelo zebhayoloji zinokubathintela ekubeni babe bakhulu ngakumbi - ixesha eliza kuthatha imithambo-luvo yokuya kwingqondo yedinosaur emalunga neenyawo ezili-100 ngokomzekelo. Inyani yokuba lonke uhlobo olukhuphisana nedinosaur enkulu kunazo zonke izihloko zexesha - kubandakanya I-Argentinosaurus , Supersaurus , kunye I-Diplodocus -Ukujikeleza ngaphezulu kwe-100 ukuya kwi-110 yeenyawo ubude kunokubonisa ukuba ezi dinosaurs zazifikelela kwisilingi yokwakheka kobungakanani bokuba babenako.

Nokuba zidibeneyo, ezi zinto zidale umda obanzi wobungakanani, kodwa bekunganyanzelekanga nika I-sauropods zabo ezinkulu Oko kuseyimfihlakalo. Mfutshane ngokutyelela i-Skull Island kunye neqela leengcali ezixhotyiswe kakuhle, i-paleodology ephuzayo, engenakunqandwa ingaba yindlela ephela yokufumanisa imfihlakalo.
