Kangangexesha elide, abantu bebephenjelelwa ngumfanekiso weedinosaur kwiscreen, kangangokuba iT-rex ithathwa njengeyona iphambili kwiintlobo ezininzi zeedinosaur. Ngokophando lwezinto zakudala, iT-rex ifanelekile ukuma phezulu kwikhonkco lokutya. Ubude beT-rex endala ngokubanzi bungaphezulu kweemitha ezili-10, kwaye amandla okuluma amangalisayo anele ukukrazula zonke izilwanyana phakathi. La manqaku mabini kuphela anele ukwenza abantu banqule le dinosaur. Kodwa ayilohlobo olunamandla lweedinosaur ezitya inyama, kwaye eyomeleleyo inokuba yiSpinosaurus.
Xa kuthelekiswa ne-T-Rex, iSpinosaurus ayidumanga kangako, nto leyo engenakwahlulwa kwimeko yokwenyani yezinto zakudala. Xa sijonga imeko yexesha elidlulileyo lezinto zakudala, izazi ze-paleontologists zinokufumana ulwazi oluthe kratya malunga neTyrannosaurus Rex kwiifosili kuneSpinosaurus, enceda abantu ukuchaza umfanekiso wayo. Imbonakalo yokwenyani yeSpinosaurus ayikaqinisekiswa. Kwizifundo zangaphambili, izazi ze-paleontologists zichonge iSpinosaurus njengedinosaur enkulu ye-theropod edla inyama kwixesha eliphakathi leCretaceous ngokusekelwe kwiifosili zeSpinosaurus ezivunjululweyo. Uninzi lwemibono yabantu ngayo ivela kwiscreen semuvi okanye kwimifanekiso eyahlukeneyo ebuyiselweyo. Kule datha, kunokubonwa ukuba iSpinosaurus ifana nezinye izilwanyana ze-theropod ngaphandle kwee-dorsal spines ezikhethekileyo emqolo wayo.
Iingcali zePaleontologists zithi iimbono ezintsha malunga neSpinosaurus
IBaryonyx iyinxalenye yosapho lweSpinosaurus ngokweendidi. Iingcali zePaleontologists zifumanise ukuba kukho amaxolo eentlanzi esiswini sefosili yeBaryonyx, zaza zacebisa ukuba iBaryonyx inokuloba. Kodwa oko akuthethi ukuba iispinosaurs ziphila emanzini, kuba neebhere nazo ziyathanda ukuloba, kodwa azizo izilwanyana zasemanzini.
Kamva, abanye abaphandi bacebisa ukusebenzisa ii-isotopes ukuvavanya iSpinosaurus, bethatha iziphumo njengobungqina bokugweba ukuba iSpinosaurus yidinosaur yasemanzini na. Emva kohlalutyo lwe-isotopic lweefosili zeSpinosaurus, abaphandi bafumanise ukuba ukusasazwa kwe-isotopic kwakusondele kakhulu kubomi basemanzini.
Ngowama-2008, uNizar Ibrahim, isazinzulu se-paleontology kwiYunivesithi yaseChicago, wafumanisa iqela leefosili zeSpinosaurus ezazahluke kakhulu kwiifosili ezaziwayo emgodini eMonaco. Eli qela leefosili lenziwa ngasekupheleni kwexesha leCretaceous. Ngokufunda iifosili zeSpinosaurus, iqela lika-Ibrahim likholelwa ukuba umzimba weSpinosaurus mde kwaye mncane kunokuba kwaziwa ngoku, unomlomo ofana nowengwenya, kwaye kusenokwenzeka ukuba ukhule iiphiko. Ezi mpawu zibonisa ukuba iSpinosaurus zizilwanyana zasemanzini okanye eziphila emanzini.
Ngowama-2018, u-Ibrahim kunye neqela lakhe bafumana amathambo eSpinosaurus eMonaco kwakhona. Ngeli xesha bafumana i-vertebra yomsila weSpinosaurus kunye neentsipho ezigcinwe kakuhle. Abaphandi bahlalutye i-vertebrae yomsila weSpinosaurus nzulu baza bafumanisa ukuba ifana nenxalenye yomzimba enezinto eziphila emanzini. Ezi ziphumo zibonelela ngobungqina obongezelelekileyo bokuba iSpinosaurus yayingesosidalwa sasemhlabeni ngokupheleleyo, kodwa yayiyidinosaur enokuphila emanzini.
YayiI-Spinosaurusidayinaso yasemhlabeni okanye yasemanzini?
Ngoko ke ngaba yidinosaur yaseSpinosaurus esemhlabeni, yidinosaur yasemanzini, okanye yidinosaur ehlala emanzini? Iziphumo zophando zika-Ibrahim kwiminyaka emibini edlulileyo zanele ukubonisa ukuba iSpinosaurus ayisosidalwa sasemhlabeni ngokupheleleyo. Ngophando, iqela lakhe lifumanise ukuba umsila weSpinosaurus wawukhula i-vertebrae kuzo zombini iindlela, kwaye ukuba wawuphinda wakhiwe, umsila wawo wawuya kufana neseyile. Ukongeza, i-vertebrae yomsila weSpinosaurus yayiguquguquka kakhulu kumlinganiselo othe tye, nto leyo ethetha ukuba babekwazi ukuvuthela imisila yabo kwiikona ezinkulu ukuze bavelise amandla okudada. Nangona kunjalo, umbuzo wokuba ngubani oyena Spinosaurus ayikagqitywa. Ngenxa yokuba akukho bungqina bokuxhasa "iSpinosaurus yidinosaur yasemanzini ngokupheleleyo", ngoko ke iingcali ezininzi ze-paleontologists ngoku zikholelwa ukuba isenokuba sisidalwa esihlala emanzini njengengwenya.
Lilonke, izazi ze-paleontologists zenze imizamo emikhulu ekufundeni iSpinosaurus, zityhila imfihlakalo yeSpinosaurus kancinci kancinci kwihlabathi. Ukuba akukho mibono kunye nokufunyanwa okuphazamisa ukuqonda okungokwemvelo kwabantu, ndikholelwa ukuba uninzi lwabantu lusacinga ukuba iSpinosaurus kunye neTyrannosaurus Rex zizilwanyana ezitya inyama emhlabeni. Yintoni ubuso bokwenyani beSpinosaurus? Masilinde sibone!
