LAKE BARREALES, Argentina - Jorge Calvo paaifamba achitevedza guruva redziva rePatagonian, akaongorora tsvina yakatsvuka, achinongedzera kusara kwedinosaur muzuva remurenje.
Achienderera mberi, akapinda mugomba remamita masere ndokusimudzira Marcela Milani, nyanzvi inoshanda nembambo hobvu nesando. Akanga achitsemukira padombo achitsvaga bhonzo rehudyu rakashaikwa rinotendwa kuva chikamu chezvakawanikwa naVaCalvo zvakanyanya kuzivikanwa, Futalognkosaurus, rudzi rutsva rwedhinasore rinodya zvirimwa rakareba mamita anopfuura zana kubva kumuswe kusvika kumhino. Ndiyo imwe yemadinosaur matatu makuru ati ambowanikwa.
"Iyeyo akararama makore anoda kusvika mamirioni makumi mapfumbamwe apfuura," akadaro Mr. Calvo, nyanzvi yeArgentina geologist uye paleontologist. "Takazara nemadinosaur pano. Kana ukafamba, uchawana chimwe chinhu.”
VaCalvo, vane makore makumi mana nematanhatu, vane hofisi yavo pano, pakucherwa kwegore rose kwezvisaririra kubva muguva guru iri. Haasi kutevedzera gwara redzidzo renyanzvi dzepapaleontologist, kuunganidza mumunda kumamiziyamu ari kure. Mushure mekuwana mapfupa eFutalognkosaurus muna 46, akagadzira chitoro pano makore maviri gare gare padziva iri rakanyorova rakamisikidzwa kune rimwe divi nematombo matsvuku akadzika anotaridzika zvakafanana neaya ekuSedona, Ariz.
VaCalvo's Dino Project, inenge mamaira makumi mashanu neshanu kuchamhembe kweguta reNeuquén, ine turera ine chitsama ine dzimba dzekugezera dzinotakurika uye muziyamu yakanyatsovakwa isina air-conditioning kana pasi kwaanoratidza kukura kwake kwezvisaririra. Kushanda uku kunowanikwa zvakanyanya pazvipo kubva kumakambani emagetsi emuno, ayo ari kuchera gasi rechisikigo munzvimbo iyi.
VaCalvo, zvisinei, vakakwanisa kukwezva vashanyi 10,000 pagore kubva kumativi ose enyika, kusanganisira vemabhizimisi vakamanikidzwa vanouya "kurapwa" kuzotsvaga zvisaririra. Anopedza mazuva mana pavhiki muBarreales, dzimwe nguva achitsvaga nyeredzi usiku nemwanakomana wake Santiago, 11. Muzhizha pano, December kusvika March, Mr. Calvo vanowanzoshanda nekushanyira paleontologists kubva kuBrazil neItaly. Achiri kudzidzisa geology uye engineering paNational University yeComahue muNeuquén, uko dinosaur yakaita seshiri yaakawana pamusasa yakatumidzwa zita rake.
Maitiro ake kune paleontology akati wandei anokakavadzana. Rodolfo Coria, a paleontologist paCarmen Funes Museum padhuze neNeuquén, akati zvisaririra zvaitorwa naVaCalvo kuBarreales vaive "nhapwa" uye zvinofanirwa kunge zviri mumyuziyamu yakakodzera. "Handibvumirani nekushandisa zvisaririra izvozvo muchirongwa chevashanyi," VaCoria vakadaro.
Nharaunda yePatagonian yeArgentina, uko VaCalvo vakashanda kwemakore makumi maviri, yava imwe yenzvimbo dzinonyanya kushanda pakuongorora zvisaririra zvemadinosaur pasi rose, pamwe chete neGobi Desert kuChina uye neAmerica West yakapfuma. Paleontologists kubva kumativi ose enyika vakakweverwa kushanda muPatagonia. Masayendisiti echiArgentina akafukunura dinosaur hombe-inodya zvirimwa, Argentinosaurus, uye mhuka hombe inodya nyama, Giganotosaurus carolinii, iyo yakareba mamita angangoita 20 yakanga yakareba zvishoma uye matani anenge matatu kurema kupfuura yakakurumbira Tyrannosaurus Rex yakawanikwa muUnited States.
“Argentina ine chinyorwa chakapfuma uye chenguva refu zvikurusa che<em>dinosaur muNyika yose yeKumaodzanyemba, chinyorwa kubva pama<em>dinosaur okutanga kusvikira kune okupedzisira,” akadaro James I. Kirkland, nyanzvi ye<em>paleontologist yehurumende neUtah Geological Survey. Iyo rekodhi, inotora makore angangoita mamirioni zana nemakumi mashanu, yakasiyanawo neiyo yeNorth Hemisphere, akadaro, nekuti panguva yeJurassic uye yakawanda yeCretaceous makondinendi aive achiputsika, achiparadzanisa Northern neSouthern Hemispheres. Mhando dzakasiyana dzemadinosaur dzakashanduka munzvimbo imwe neimwe. Asi makore anosvika mamiriyoni makumi manomwe apfuura, makore mamiriyoni mashanu chete ma<em>dinosaurs asati atsakatika, zambuko renyika rakaumbwa rakabvumira mamwe ma<em>dinosaur kubva kune imwe nyika kuti ayambuke.
Zvisaririra zvemadinosaurs kubva kuCretaceous period (makore 145 kusvika 65 emamiriyoni apfuura) zvave zvakanyanya kutenderera Neuquén. "Tinoitumidza kuti Cretaceous Park," VaCalvo vakataura nezvemakuva edinosaur, anosanganisira Lake Barreales.
Zvisaririra zvemadhinasa zvokutanga zvenyika zvakawanwa pedyo neNeuquén muna 1882. Kwemakumi emakore mamiziyamu muBuenos Aires neLa Plata, pedyo neguta guru, aiita seaiunganidza zvisaririra zvose zvomunzvimbo yacho. Kuvakwa kwemamyuziyamu ematunhu akatenderedza Neuquén makumi maviri emakore apfuura kwakabatsira kuchengetedza zvisaririra kumba uye kwakagadzira mhando yedino-tourism.
Vamwe vakapesvedzera hutsva huchangobva kuwanwa hwekuda kunyanyisa. Ruben Carolini, mukuru we dinosaur museum muEl Chocón, pedyo neNeuquén, anonzi akazvisunga necheni kumapfupa eGiganotosaurus muna 2006 achida kuti mafossils uye replicas zvakatumirwa kuBuenos Aires uye mhiri kwemakungwa zvidzoserwe kunzvimbo yake. Mushure memaawa akati wandei, akazvisunungura mushure mekunge dehenya rakavakwa patsva remudyi wenyama, rakanga raenda kuBuenos Aires, rakadzoserwa kuEl Chocón.
Asati ari mutungamiriri we museum, Mr. Carolini akanga ari auto mechanic uye dinosaur-kuvhima hobbyist uyo aityaira dune buggy uye akapfeka Indiana Jones hat. Akave nemukurumbira muna 1993 nekuwana kwake gumbo bhonzo reGiganotosaurus, akakwezva nharaunda uye akakwevera kutarisisa kune dzimwe nyika.
Kune rumwe rutivi, VaCalvo vanorota kushandura nzvimbo yavo yega kuti ive yakatokura yekushanya. Akaratidza muenzaniso wakaenzana we $2 miriyoni paleontology miziyamu iyo ingadai ine mugero wakaputika nepamusoro pegomo redombo dzvuku rinotungamira kune chikamu chakatsaurirwa kunhoroondo yeMapuche Indians.
"Ndaigona kutsvaga mapfupa edhinaso kwehupenyu hwangu hwese uye humwe humwe hupenyu huviri asi ndisati ndaitwa," akadaro. "Chimwe chinhu chatiinacho pano inguva."
