ILake BARREALES, eArgentina-Njengokuba uJorge Calvo wayehamba ecaleni konxweme olunethuli lweli chibi lasePatagonian, wajonga ubumdaka obomvu, ekhomba kwintsalela yedayinaso kwilanga eliyintlango.
Eqhubeleka, enyonyoba ezantsi emngxunyeni oziimitha ezisibhozo waza wawangawangisa waya kuMarcela Milani, igcisa elisebenza ngesikhonkwane esingqindilili kunye nehamile. Wayegqwashula elityeni ekhangela ithambo lenyonga elingekhoyo ekukholelwa ukuba liyinxalenye yeyona nto idumileyo kaMnu. Calvo, iFutalognkosaurus, uhlobo olutsha lwedayinaso etya izityalo ezingaphezulu kweemitha ezili-100 ubude ukusuka emsileni ukuya empumlweni. Yenye yeedinosaur ezintathu ezinkulu ezakha zafunyanwa.
“Lowo wayephila kwiminyaka emalunga nezigidi ezingama-90 eyadlulayo,” watsho uMnu. “Sizele ziidayinaso apha. Ukuba uhamba, uya kufumana into. "
UMnu. Calvo, 46, une-ofisi yakhe apha, ekugrunjweni konyaka wonke kweefosili kweli ngcwaba likhulu ledayinaso. Akalandeli indlela yemfundo yemveli yeengcali zamandulo, ukuqokelela ebaleni kwiimyuziyam ezikude. Emva kokufumana amathambo e-Futalognkosaurus ngo-2000, waseka ivenkile apha kwiminyaka emibini kamva ecaleni kweli chibi lenziweyo elithambileyo elibekwe kwelinye icala ngamatye abomvu ajongeka ngokufanayo nalawo aseSedona, e-Ariz.
Iprojekthi yeDino kaMnu. Calvo, malunga neekhilomitha ezingama-55 kumntla wesixeko saseNeuquén, iqulathe iitreyila ezimbalwa ezinamagumbi okuhlambela aphathwayo kunye nemyuziyam eyakhiwe kancinci ngaphandle kwe-air-conditioning okanye umgangatho apho abonisa khona ukukhula kwakhe kweefosili. Lo msebenzi ukho kakhulu kwiminikelo evela kwiinkampani zamandla zalapha ekhaya, ezombela irhasi yendalo kule ndawo.
UMnu. Calvo, nangona kunjalo, ukwazile ukutsala abakhenkethi abangama-10,000 ngonyaka abavela kwihlabathi liphela, kuquka oosomashishini abaxinezelekileyo abeza “kunyango” ukukhangela iifosili. Uchitha iintsuku ezine ngeveki eBarreales, ngamanye amaxesha efuna iinkwenkwezi ebusuku kunye nonyana wakhe uSantiago, oneminyaka eyi-11. Ehlotyeni apha, ngoDisemba ukuya kuMatshi, uMnumzana Calvo uhlala esebenza kunye nokutyelela i-paleontologists evela eBrazil nase-Italy. Usafundisa i-geology kunye nobunjineli kwiYunivesithi yeSizwe yaseComahue eNeuquén, apho idayinaso efana nentaka ayifumene kwikhampasi yathiywa ngaye.
Indlela yakhe kwi-paleontology iyaphikisana. U-Rodolfo Coria, i-paleontologist kwiMyuziyam yaseCarmen Funes kufuphi ne-Neuquén, uthe iifosili zikaMnu. “Andivumelani nokusebenzisa ezo fosili kwiprojekthi yabakhenkethi,” utshilo uMnu. Coria.
Ummandla wasePatagonian waseArgentina, apho uMnumzana Calvo esebenze khona iminyaka engama-20, uye waba yenye yezona ndawo zisebenzayo zokuhlola iifosili zedayinaso ehlabathini, kunye neNtlango yaseGobi eChina kunye neNtshona yaseMelika etyebileyo ngamathambo. Iingcali zePaleontologists ezivela kwihlabathi jikelele ziye zatsalwa ukuba zisebenze ePatagonia. Izazinzulu zase-Argentina zifumene i-dinosaur enkulu etya izityalo, i-Argentinosaurus, kunye ne-carnivore enkulu kunazo zonke, i-Giganotosaurus carolinii, eyayimalunga neemitha ezingama-42 ubude kwaye yayimalunga neetoni ezintathu ezinzima kune-Tyrannosaurus Rex eyaziwayo efunyenwe eUnited States.
UJames I. Kirkland, isazi sezidalwa zamandulo sase-Utah se-Utah Geological Survey wathi: “IArgentina ineyona rekhodi ityebileyo nehlala ixesha elide yee<em>dinosaur kuwo wonke uMzantsi weIkhweyitha. Elo rekhodi, elithatha malunga ne-150 yezigidi zeminyaka, likwahlukile kuMntla weHemisphere, wathi, kuba ngexesha leJurassic kunye noninzi lweCretaceous amazwekazi ayeqhekeka, esahlula i-Northern and Southern Hemispheres. Iintlobo ezahlukeneyo zeedayinaso zavela kwindawo nganye. Kodwa malunga ne-70 yezigidi zeminyaka edlulileyo, nje izigidi ezi-5 zeminyaka ngaphambi kokuba iidinosaurs ziphele, ibhulorho yomhlaba eyayenziwe yavumela ezinye iidinosaurs ukusuka kwi-hemisphere nganye ukuba ziwele.
Iifosili zeedinosaur zexesha leCretaceous (iminyaka eyi-145 ukuya kwi-65 yezigidi eyadlulayo) zixhaphake kakhulu eNeuquén. “Siyibiza ngokuba yiCretaceous Park,” utshilo uMnu. Calvo malunga namangcwaba e-dinosaur, aquka iLake Barreales.
Iifosili zokuqala zedayinaso zeli lizwe zafunyanwa kufuphi neNeuquén ngowe-1882. Kangangamashumi eminyaka iimyuziyam zaseBuenos Aires naseLa Plata, kufutshane nekomkhulu, zabonakala ziqokelela zonke iifosili zalo mmandla. Ukwakhiwa kweemyuziyam zengingqi malunga neNeuquén kwiminyaka engamashumi amabini edlulileyo kuye kwanceda ukugcina iifosili ekhaya kwaye zenze uhlobo lwe-dino-tourism.
Abanye baye baluthatha ngokugqithisileyo olu tshintsho. URuben Carolini, intloko yemyuziyam ye-dinosaur e-El Chocón, kufuphi ne-Neuquén, kwaxelwa ukuba wazibophelela kwi-fossil skeleton ye-Giganotosaurus ngo-2006 efuna ukuba iifosili kunye neekopi ezithunyelwe eBuenos Aires naphesheya zibuyiselwe kwiziko lakhe. Emva kweeyure ezininzi, wazikhulula emva kokuba ukhakhayi olwakhiwe ngokutsha lwenyama, olwalusingise eBuenos Aires, lwabuyiselwa e-El Chocón.
Ngaphambi kokuba abe ngumlawuli wemyuziyam, uMnumzana Carolini wayengumkhandi wemoto kunye nokuzingela i-dinosaur hobbyist owayeqhuba i-buggy ye-dune kwaye enxibe i-Indiana Jones hat. Waduma ngo-1993 ngokufumanisa kwakhe ithambo lomlenze we-Giganotosaurus, owathi watsala umdla waloo ndawo kwaye watsala umdla wamazwe ngamazwe.
Kwelakhe icala, uMnu. Calvo unephupha lokuguqula indawo yakhe eyedwa ibe yindawo enkulu yokhenketho. Ubonise imodeli yesikali yemyuziyam ye-paleontology exabisa i-2 yezigidi zeedola enokuthi ibe netonela eliqhushumba kwintaba ebomvu yelitye elikhokelela kwicandelo elinikelwe kwimbali yamaIndiya omthonyama angamaMapuche.
“Bendinokukhangela amathambo edayinaso ubomi bam bonke kunye nobomi obubini obungakumbi kwaye ndingenzeki,” utshilo. "Inye into esinayo apha lixesha."
