Sekuyisikhathi eside abantu bethonywe isithombe sama-dinosaurs esikrinini, ukuze i-T-rex ibhekwe njengephezulu kwezinhlobo eziningi ze-dinosaur.Ngokocwaningo lwemivubukulo, i-T-rex ifaneleka ngempela ukuma phezulu ochungechungeni lokudla.Ubude be-T-rex endala ngokuvamile bungaphezu kwamamitha angu-10, futhi amandla okuluma amangalisayo anele ukuklebhula zonke izilwane phakathi.La maphuzu amabili ewodwa anele ukwenza abantu bakhonze le dinosaur.Kodwa akulona uhlobo oluqine kakhulu lwama-dinosaurs adla inyama, futhi olunamandla kungase kube i-Spinosaurus.
Uma kuqhathaniswa no-T-Rex, i-Spinosaurus ayidume kangako, engenakuhlukaniswa nesimo sangempela semivubukulo.Uma sibheka isimo esidlule semivubukulo, izazi ze-paleontologists zingathola ulwazi olwengeziwe mayelana ne-Tyrannosaurus Rex emivubukulweni kune-Spinosaurus, esiza abantu ukuchaza isithombe sayo.Ukubukeka kweqiniso kwe-Spinosaurus akukakanqunywa.Ezifundweni ezedlule, izazi ze-paleontologists ziye zahlonza i-Spinosaurus njenge-dinosaur enkulu ye-theropod carnivorous phakathi nenkathi ye-Cretaceous esekelwe kumathambo e-Spinosaurus ambiwe.Iningi lemibono yabantu ngayo ivela esikrinini se-movie noma ezithombeni ezahlukahlukene ezibuyiselwe.Kusukela kule datha, kungabonakala ukuthi i-Spinosaurus iyafana nezinye izilwane ezidla inyama ze-theropod ngaphandle kwemigogodla ekhethekile emhlane wayo.
Izazi ze-paleontologists zithi imibono emisha mayelana ne-Spinosaurus
I-Baryonyx ingeyomndeni wakwaSpinosaurus ngokwezigaba.Izazi ze-paleontologists zathola ukuthi kukhona amazenga ezinhlanzi esiswini se-Baryonyx fossil, futhi zaphakamisa ukuthi i-Baryonyx ingadoba.Kodwa lokho namanje akusho ukuthi ama-spinosaur ahlala emanzini, ngoba amabhere nawo ayakuthanda ukudoba, kodwa awazona izilwane zasemanzini.
Kamuva, abanye abacwaningi bahlongoza ukusebenzisa ama-isotopes ukuhlola i-Spinosaurus, bethatha imiphumela njengobunye bobufakazi bokwahlulela ukuthi i-Spinosaurus iyi-dinosaur yasemanzini.Ngemuva kokuhlaziywa kwe-isotopic kwezinsalela ze-Spinosaurus, abacwaningi bathola ukuthi ukusatshalaliswa kwe-isotopic kwakuseduze nalokho kwempilo yasemanzini.
Ngo-2008, u-Nizar Ibrahim, isazi se-paleontologist e-University of Chicago, wathola iqembu lezinsalela ze-Spinosaurus ezazihluke kakhulu kwezinsalela ezaziwayo emayini eMonaco.Leli qoqo lezinsalela lakhiwa ngasekupheleni kwesikhathi seCretaceous.Ngocwaningo lwezinsalela ze-Spinosaurus, ithimba lika-Ibrahim likholelwa ukuthi umzimba we-Spinosaurus mude futhi uzacile kunalokho owaziwayo njengamanje, onomlomo ofana nowengwenya, futhi kungenzeka ukuthi ukhule amaphiko.Lezi zici zikhomba i-Spinosaurus njengezilwane zasemanzini noma ezihlala emanzini.
Ngo-2018, u-Ibrahim nethimba lakhe bathola izinsalela ze-Spinosaurus eMonaco futhi.Kulokhu bathole i-Spinosaurus yomsila kanye nezinzipho ezigcinwe kahle.Abacwaningi bahlaziye ama-vertebrae omsila we-Spinosaurus ngokujula futhi bathola ukuthi ifana nengxenye yomzimba ephethwe izidalwa zasemanzini.Lokhu okutholakele kunikeza ubufakazi obengeziwe bokuthi i-Spinosaurus yayingesona isidalwa sasemhlabeni ngokuphelele, kodwa i-dinosaur engaphila emanzini.
KwakunjaloI-Spinosaurusi-dinosaur yasemhlabeni noma yasemanzini?
Ngakho ingabe i-Spinosaurus dinosaur yasemhlabeni, i-aquatic dinosaur, noma i-amphibious dinosaur?Okutholwe ocwaningweni luka-Ibrahim eminyakeni emibili edlule bekwanele ukukhombisa ukuthi i-Spinosaurus ayisona isidalwa sasemhlabeni ngomqondo ogcwele.Ngokucwaninga, ithimba lakhe lithole ukuthi umsila we-Spinosaurus wakhula ama-vertebrae kuzo zombili izinkomba, futhi uma wakhiwe kabusha, umsila wawo wawuzofana noseyili.Ngaphezu kwalokho, ama-vertebrae omsila we-Spinosaurus ayeguquguquka kakhulu endaweni evundlile, okusho ukuthi ayekwazi ukuphephetha imisila yawo ngama-engeli amakhulu ukuze akhiqize amandla okubhukuda.Kodwa-ke, umbuzo wokuthi ungubani ngempela i-Spinosaurus awukakaphethwa.Ngenxa yokuthi abukho ubufakazi obusekela ukuthi “i-Spinosaurus iyi-dinosaur yasemanzini ngokuphelele”, ngakho izazi ze-paleontology ezengeziwe manje zikholelwa ukuthi kungenzeka isidalwa esiphila emanzini njengengwenya.
Sekukonke, izazi ze-paleontologists zenze imizamo emikhulu ocwaningweni lwe-Spinosaurus, zembula imfihlakalo ye-Spinosaurus kancane kancane emhlabeni.Uma ingekho imicabango kanye nokutholwayo okuchitha ukuqashelwa okungokwemvelo kwabantu, ngikholwa ukuthi abantu abaningi basacabanga ukuthi i-Spinosaurus ne-Tyrannosaurus Rex ziyizilwane ezidla inyama zasemhlabeni.Buyini ubuso beqiniso be-Spinosaurus?Ake silinde sibone!
