Kwangexesha elide, abantu baye bathonywa ngumfanekiso weedinosaurs kwisikrini, ukwenzela ukuba i-T-rex ithathwa njengeyona nto iphezulu kwiintlobo ezininzi ze-dinosaur.Ngokophando lwe-archaeological, i-T-rex ngokwenene ifanelekile ukuma phezulu kwikhonkco lokutya.Ubude bomntu omdala we-T-rex ngokuqhelekileyo bungaphezu kweemitha ezili-10, kwaye amandla okuluma amangalisayo anele ukukrazula zonke izilwanyana kwisiqingatha.La manqaku mabini ewodwa anele ukwenza abantu banqule le dinosaur.Kodwa ayilona hlobo lunamandla lweedinosaurs ezidla inyama, kwaye eyona inamandla inokuba yiSpinosaurus.
Xa kuthelekiswa ne-T-Rex, i-Spinosaurus ayidumanga kangako, engenakuhlukaniswa kwimeko yokwenyani yezinto zakudala.Ukujonga imeko ye-archaeological yangaphambili, i-paleontologists inokufumana ulwazi oluninzi malunga neTyrannosaurus Rex kwiifosili kuneSpinosaurus, enceda abantu ukuba bachaze umfanekiso wayo.Imbonakalo yokwenyani yeSpinosaurus ayikaqinisekwa.Kwizifundo ezidlulileyo, i-paleontologists ichonge i-Spinosaurus njenge-giant theropod carnivorous dinosaur phakathi kwexesha le-Cretaceous esekelwe kwiifosili ze-Spinosaurus ezigqwesileyo.Uninzi lwabantu abalubonayo luvela kwiscreen semovie okanye kwimifanekiso eyahlukeneyo ebuyiselweyo.Kwezi datha, kunokubonwa ukuba i-Spinosaurus iyafana nezinye i-theropod carnivores ngaphandle kwe-dorsal spines ekhethekileyo emqolo wayo.
Iipaleontologists zithi iimbono ezintsha malunga neSpinosaurus
IBaryonyx yeyosapho lweSpinosaurus kuhlelo.Iingcali zePaleontologists zafumanisa ubukho bamaxolo entlanzi esiswini se-Baryonyx fossil, kwaye zacebisa ukuba iBaryonyx inokuloba.Kodwa ke loo nto ayithethi ukuba i-spinosaurs ziphila emanzini, kuba iibhere nazo ziyathanda ukuloba, kodwa azizozilwanyana zasemanzini.
Kamva, abanye abaphandi bacebise ukusebenzisa i-isotopes ukuvavanya i-Spinosaurus, bethatha iziphumo njengenye yobungqina bokugweba ukuba i-Spinosaurus yi-dinosaur yasemanzini.Emva kohlalutyo lwe-isotopic yeefosili ze-Spinosaurus, abaphandi bafumanisa ukuba ukuhanjiswa kwe-isotopic kwakusondele kubomi basemanzini.
Ngo-2008, u-Nizar Ibrahim, i-paleontologist kwiYunivesithi yaseChicago, wafumanisa iqela leefosili ze-Spinosaurus ezazihluke kakhulu kwiifosili ezaziwayo kumgodi waseMonaco.Eli qela leefosili lasekwa ekupheleni kwexesha leCretaceous.Ngokuphononongwa kweefosili ze-Spinosaurus, iqela lika-Ibrahim likholelwa ukuba umzimba we-Spinosaurus mde kwaye ubhityile kunowaziwayo ngoku, unomlomo ofana nowengwenya, kwaye kusenokwenzeka ukuba ukhule amaphiko.Ezi mpawu zibonisa i-Spinosaurus ukuba yi-aquatic okanye i-amphibians.
Ngo-2018, u-Ibrahim kunye neqela lakhe bafumana iifosili ze-Spinosaurus eMonaco kwakhona.Ngeli xesha bafumene i-Spinosaurus yomsila kunye neenzipho ezigcinwe kakuhle.Abaphandi bahlalutya i-vertebrae yomsila we-Spinosaurus ngobunzulu kwaye bafumanisa ukuba ifana nenxalenye yomzimba ophethwe zizidalwa zasemanzini.Ezi ziphumo zibonelela ngobungqina obungakumbi bokuba iSpinosaurus yayingesiso isidalwa sasemhlabeni ngokupheleleyo, kodwa yayiyidayinaso enokuhlala emanzini.
KwakunjaloI-Spinosaurusidayinaso yasemhlabeni okanye yasemanzini?
Ke ngaba iSpinosaurus idayinaso yasemhlabeni, idayinaso yasemanzini, okanye idayinaso ehlala emanzini?Iziphumo zophando zika-Ibrahim kwiminyaka emibini edlulileyo zanele ukubonisa ukuba i-Spinosaurus ayisosidalwa sasemhlabeni ngokupheleleyo.Ngophando, iqela lakhe lafumanisa ukuba umsila we-Spinosaurus ukhule i-vertebrae kumacala omabini, kwaye ukuba yakhiwe ngokutsha, umsila wayo uya kufana neseyile.Ukongeza, i-vertebrae yomsila we-Spinosaurus yayiguquguquka kakhulu kumda othe tyaba, nto leyo ethetha ukuba babekwazi ukubetha imisila yabo kwii-engile ezinkulu ukuvelisa amandla okuqubha.Nangona kunjalo, umbuzo wesazisi sokwenyani seSpinosaurus awukagqitywa.Ngenxa yokuba akukho bungqina bokuxhasa "i-Spinosaurus yi-dinosaur yasemanzini ngokupheleleyo", ngoko ke i-paleontologists engaphezulu ngoku ikholelwa ukuba inokuba sisidalwa esihlala emanzini njengengwenya.
Lilonke, ii-paleontologists zenze iinzame ezinkulu kuphononongo lweSpinosaurus, zityhila imfihlakalo yeSpinosaurus kancinci kancinci kwihlabathi.Ukuba akukho zithiyori kunye nezinto ezifunyanisiweyo eziphambukisa ukuqonda kwabantu, ndiyakholelwa ukuba uninzi lwabantu lusacinga ukuba iSpinosaurus kunye neTyrannosaurus Rex zizilwanyana ezitya inyama.Yintoni ubuso bokwenyani beSpinosaurus?Masilinde sibone!
