Obunye ubuciko be-rock basendulo bubonisa okhokho bethu ukushiya okunenjongo kwemigxivizo yezandla, okunikeza uphawu oluhlala njalo lokuba khona kwazo. Ukuphrinta okushaqisayo okutholwe ebusweni betshe e-Bolivia kwakungamamaki angahlosiwe adalwe abadwebi abangenangqondo.
Kwesinye isikhathi, uchungechunge lwemicimbi enenhlanhla luholela entweni edidayo emhlabeni. Esinye salezi zibonelo izindlela eziningi zama-dinosaur ezitholwe zihlobisa lokho okubonakala kuwudonga olume mpo.
Izinyathelo odongeni
I-Cal Orcko iyindawo emnyangweni weChuquisaca eningizimu emaphakathi neBolivia, eduze naseSucre, inhloko-dolobha yomthethosisekelo wezwe. Le ndawo iyikhaya leParque Cretácico (okusho "Cretaceous Park"), edume ngokuba nenani eliphakeme kakhulu lezinyawo ze-dinosaur emhlabeni odongeni.
Ukuthola indawo ye-dinosaur eyodwa ngezigidi zeminyaka ubudala kuyajabulisa, kodwa ukuthola abangu-1000 endaweni eyodwa kuyinto emangalisayo. Abavubukuli baye babonisa ukuthi a "i-dinosaur dancefloor," enezingqimba zezinyawo ezakha iphethini yamathrekhi achanyuselwe.
Izazi ze-paleontologists zikwazile ukuhlonza ezinye zezinhlobo eziningana zama-dinosaurs ayehlala endaweni, edla, elwa, futhi ebaleka emqhudelwaneni ogcine ungenalutho wokuba khona ngenxa yalezi zimpawu.
Ukuphazamisa ama-dinosaurs
I-Cal Orcko isho ukuthi "intaba ye-lime" ngolimi lwendabuko lwesiQuechua futhi ibhekisela ohlotsheni lwetshe elitholakala endaweni, okuyi-limestone. Le ndawo isendaweni ye-FANCESA, inkampani kazwelonke kasimende yaseBolivia.
Le femu kasimende isinezimayini ze-limestone amashumi amaningi eminyaka, futhi yizisebenzi zayo ezathola izinyathelo zokuqala ze-dinosaur ngo-1985 eCal Orcko. Nokho, kwaze kwaba yiminyaka eyisishiyagalolunye kamuva, ngo-1994, lapho udonga olukhulu lwethrekhi ye-dinosaur lwembulwa umsebenzi wezimayini.
Naphezu kweqiniso lokuthi izazi ze-paleontology zase ziqalile ukuhlola amathrekhi ama-dinosaur, ukuchayeka endaweni ezungezile nemisebenzi yezimayini kwabangela ukuba udonga luguguleke futhi lubhidlize. Ngenxa yalokho, le ndawo yavalwa iminyaka eyisishiyagalombili ukuze kube khona okwenziwayo ukuze kulondolozwe lolu donga olubalulekile. Ngenxa yalokho, ngo-2006, iParque Cretácico yavulelwa izivakashi.
Udonga lwe-dinosaur lodumo
Udonga lwethrekhi ye-dinosaur, olucishe lube ngu-80 m ukuphakama kanye no-1200 m ubude, ngokungangabazeki luheha kakhulu leli paki. Isamba sezinyathelo zamadinosaur ezingama-5055 zitholwe kule ndawo. Ngenxa yalokho, kuye kwathiwa lolu donga luhlala iqoqo elikhulu kunawo wonke emhlabeni lezinyawo zama-dinosaur.
Izazi ze-paleontologists eziphenya odongeni zathola ukuthi izinyathelo zezinyawo zazihlukaniswe ngamathrekhi angama-462, okuzivumela ukuthi zibone izinhlobo ezifika kwezingu-15 zama-dinosaurs. Lezi zihlanganisa ama-ankylosaurs, i-Tyrannosaurus rex, i-ceratops, nama-titanosaurs, konke okwakukhona phakathi nenkathi ye-Cretaceous, ngaleyo ndlela igama lepaki.
Ayebekwa kanjani amathrekhi?
Kuye kwacatshangwa ukuthi indawo yaseSucre yake yaba indawo enkulu yolwandle, kanti iCal Orcko iyingxenye yogu lwayo. Phakathi nenkathi yeCretaceous, ama-dinosaurs ayehamba kulolu gwini lolwandle, eshiya imibhalo yawo obumba oluthambile, olwalugcinwa lapho ubumba luqina ngezikhathi ezomile.
Ungqimba lwangaphambili lwenhlabathi lwaluzombozwa ungqimba olusha lwenhlabathi, futhi inqubo yayizoqala futhi. Ngenxa yalokho, ngokuhamba kwesikhathi, kwakhiqizwa izingqimba eziningi zamathrekhi ama-dinosaur. Lokhu kwabonakala ngo-2010 ngesikhathi kuwa ingxenye yodonga. Nakuba lokhu kulimaza amanye amathrekhi, kuphinde kwadalula isendlalelo esengeziwe sezinyathelo zezinyawo ngaphansi kwawo.
Ukwakhiwa kodonga
Ngokusekelwe ekubeni khona kwezinhlobo zamanzi ahlanzekile emininingwaneni yezinsalela, kucatshangwa ukuthi indawo yokungena olwandle ekugcineni yaba ichibi elingalodwa elinamanzi ahlanzekile.
Ngaphezu kwalokho, ngenxa yokunyakaza kwamapuleti e-tectonic phakathi nenkathi Yemfundo Ephakeme, umgwaqo ama-dinosaur ayehamba kuwo ngaphambili waphoqeleka ukuba uphakame, waba udonga olucishe lume mpo.
Yilokhu okubangele ukubonakala kwamathrekhi we-dinosaur akhuphuka odongeni namuhla. Udonga lwamawa belufinyeleleka ngokukhululekile kumphakathi, kodwa eminyakeni yamuva nje, izivakashi bezikwazi ukulibona nje endaweni yesikhulumi phakathi kwepaki.
Umzila omusha wokuhamba, nokho, usudaliwe ovumela izivakashi ukuthi zifinyelele phakathi kwamamitha ambalwa odonga, okuzinikeza ukufinyelela okuseduze kakhulu emilonyeni yezinyawo ze-dinosaur.
Ikusasa eliqinisekile
Enye yezinkathazo eziyinhloko ngodonga lwethrekhi ye-dinosaur ukuthi iyiwa le-limestone. Izingcezu zamadwala ezingase zihlukane futhi ziwe eweni zingase zibhekwe njengosongo lokuphepha.
Okukhathazayo ukuthi, kulinganiselwa ukuthi uma ojantshi bengavikelekile kahle, bazocekelwa phansi ukuguguleka komhlaba wonke ngo-2020. Ngenxa yalokho, leli paki lizama ukuqokwa njengendawo Yamagugu Omhlaba ye-UNESCO, okuzolinikeza uxhaso lwezimali ukuze liqhubeke. imizamo yokongiwa kwemvelo.
