Sekuyisikhathi eside abantu bethonywe isithombe sama-dinosaur esikrinini, ngakho-ke i-T-rex ibhekwa njengephezulu kwezinhlobo eziningi zama-dinosaur. Ngokusho kocwaningo lwemivubukulo, i-T-rex iyafaneleka ngempela ukuma phezulu kochungechunge lokudla. Ubude be-T-rex endala ngokuvamile bungaphezu kwamamitha ayi-10, futhi amandla okuluma amangalisayo anele ukudabula zonke izilwane phakathi. La maphuzu amabili kuphela anele ukwenza abantu bakhulekele le dinosaur. Kodwa akuyona uhlobo olunamandla kakhulu lwama-dinosaur adla inyama, futhi enamandla kakhulu kungaba yi-Spinosaurus.
Uma kuqhathaniswa ne-T-Rex, i-Spinosaurus ayidumile kangako, okuyinto engahlukaniseki nesimo sangempela sezinto zakudala. Uma sibheka isimo sezinto zakudala esidlule, izazi ze-paleontologists zingathola ulwazi olwengeziwe mayelana ne-Tyrannosaurus Rex ezintweni zakudala kune-Spinosaurus, esiza abantu ukuchaza isithombe sayo. Ukubonakala kwangempela kwe-Spinosaurus akukakaqinisekiswa. Ezifundweni ezedlule, izazi ze-paleontologists zikhombe i-Spinosaurus njenge-dinosaur enkulu ye-theropod edla inyama phakathi nenkathi ye-Cretaceous ngokusekelwe ezintweni zakudala ze-Spinosaurus ezivubukuliwe. Iningi lemibono yabantu ngayo ivela esikrinini se-movie noma ezithombeni ezahlukahlukene ezibuyiselwe. Kusukela kule datha, kungabonakala ukuthi i-Spinosaurus ifana nezinye izilwane ezidla inyama ze-theropod ngaphandle kwe-dorsal spines ekhethekile emhlane wayo.
Izazi ze-Paleontologists zithi imibono emisha nge-Spinosaurus
I-Baryonyx ingeyomndeni wakwaSpinosaurus ngokwezigaba. Izazi ze-paleontologists zathola ukuthi kukhona ama-fish scales esiswini se-Baryonyx fossil, futhi zaphakamisa ukuthi i-Baryonyx ingadoba. Kodwa lokho akusho ukuthi ama-spinosaur ahlala emanzini, ngoba namabhere nawo ayathanda ukudoba, kodwa awazona izilwane zasemanzini.
Kamuva, abanye abacwaningi basikisela ukusebenzisa ama-isotope ukuhlola i-Spinosaurus, bethatha imiphumela njengobunye bobufakazi bokwahlulela ukuthi i-Spinosaurus iyi-dinosaur yasemanzini. Ngemva kokuhlaziywa kwe-isotopic kwama-fossils e-Spinosaurus, abacwaningi bathole ukuthi ukusatshalaliswa kwe-isotopic kwakuseduze nokokuphila kwasemanzini.
Ngo-2008, uNizar Ibrahim, isazi se-paleontologist eNyuvesi yaseChicago, wathola iqembu lezinsalela ze-Spinosaurus ezazihluke kakhulu kwezinsalela ezaziwayo emayini eMonaco. Leli qoqo lezinsalela lakhiwa ngasekupheleni kwesikhathi se-Cretaceous. Ngokutadisha izinsalela ze-Spinosaurus, ithimba lika-Ibrahim likholelwa ukuthi umzimba we-Spinosaurus mude futhi mncane kunalokho okwaziwa njengamanje, unomlomo ofana nowengwenya, futhi kungenzeka ukuthi ukhule amaphiko. Lezi zici zikhomba ukuthi i-Spinosaurus yizilwane zasemanzini noma eziphila emanzini.
Ngo-2018, u-Ibrahim nethimba lakhe bathola izinsalela zeSpinosaurus eMonaco futhi. Kulokhu bathola ithambo lomgogodla nezinzipho zomsila weSpinosaurus ezigcinwe kahle. Abacwaningi bahlaziye ngokujulile ithambo lomgogodla lomsila weSpinosaurus futhi bathola ukuthi lifana kakhulu nengxenye yomzimba ephethwe yizidalwa zasemanzini. Lokhu okutholakele kunikeza ubufakazi obengeziwe bokuthi iSpinosaurus yayingeyona ngokuphelele isidalwa sasemhlabeni, kodwa yayiyidayinaso engaphila emanzini.
KwakunguI-Spinosaurusidayinaso yasemhlabeni noma yasemanzini?
Ngakho-ke i-dinosaur yaseSpinosaurus yasemhlabeni, i-dinosaur yasemanzini, noma i-dinosaur yasemanzini? Okutholakele kocwaningo luka-Ibrahim eminyakeni emibili edlule kwanele ukukhombisa ukuthi i-Spinosaurus ayisona isidalwa sasemhlabeni ngomqondo ophelele. Ngocwaningo, ithimba lakhe lithole ukuthi umsila we-Spinosaurus wakhula ama-vertebrae kuzo zombili izinhlangothi, futhi uma wakhiwa kabusha, umsila wawo wawuzofana noseyili. Ngaphezu kwalokho, ama-vertebrae omsila we-Spinosaurus ayeguquguquka kakhulu ngobukhulu obuvundlile, okusho ukuthi ayekwazi ukuvunguza imisila yawo ngama-engeli amakhulu ukuze akhiqize amandla okubhukuda. Kodwa-ke, umbuzo wokuthi i-Spinosaurus ingubani ngempela awukaphethwa. Ngoba abukho ubufakazi obusekela ukuthi "i-Spinosaurus iyi-dinosaur yasemanzini ngokuphelele", ngakho-ke izazi ze-paleontologists eziningi manje zikholelwa ukuthi kungaba isidalwa sasemanzini esifana nengwenya.
Sekukonke, izazi ze-paleontologists zenze imizamo emikhulu ekufundweni kwe-Spinosaurus, zembula imfihlakalo ye-Spinosaurus kancane kancane emhlabeni. Uma kungekho mibono nokutholwa okuphazamisa ukuqonda okungokwemvelo kwabantu, ngikholwa ukuthi abantu abaningi basacabanga ukuthi i-Spinosaurus ne-Tyrannosaurus Rex yizilwane ezidla inyama zasemhlabeni. Buyini ubuso bangempela be-Spinosaurus? Ake silinde sibone!
