Emzamweni wethu wokwembula izimfihlo zesikhathi esedlule sakudala soMhlaba, kwesinye isikhathi ukutholwa okumangazayo kwenziwa ezindaweni ezingalindelekile kakhulu. Kunjalo lapho kumbiwa kwamuva nje phakathi nokuthuthukiswa kwepayipi lamanzi angcolile e-Auckland, eNew Zealand.
Ukwembula idiphozi ecebile nehlukahlukene yezinsalela zakudala esukela phakathi kweminyaka eyizigidi ezi-3 nezingu-3.7, lokhu okutholakele okumangalisayo kunikeza umbono oyingqayizivele wezinto eziphilayo zasolwandle zenkathi ye-Late Pliocene. Ishicilelwe kokuhlonishwayo I-New Zealand Journal of Geology and Geophysics, lolu cwaningo alugcini nje ngokusikhanyisela ngomlando we-paleontological waseNew Zealand kodwa futhi luqokomisa ukubaluleka kokubambisana phakathi kwemikhakha ehlukene ekulondolozeni nasekufundeni la marekhodi ayigugu.
Ukutholwa ngengozi: Ukuthuthukiswa kwepayipi lamanzi angcolile
Ngo-2020, njengengxenye yokuthuthukiswa kwepayipi lamanzi angcolile e-Auckland, abasebenzi bathola okungaphezu nje kokulungiswa kabusha kwepayipi. Ngaphansi kwawo kwakunenqolobane yezinsalela ezifihlwe ngaphakathi kwegobolondo lasendulo. Ekuhlanganisweni okungalindelekile kokwakhiwa kanye ne-paleontology, ukumba kwavubukula izinsalela ezingaphezu kuka-300,000 266 zezinhlobo ezingu-XNUMX ezihlukahlukene. Ngokumangalisayo, phakathi kwalezi zibonelo, izazi ze-paleontology zathola izinhlobo eziyishumi ezazingaziwa ngaphambili, zaqala isahluko esisha somlando woMhlaba obulokhu ugubuzelwe yimfihlakalo kuze kube manje.
Ukubheka ezikhathini zangaphambi komlando
Izinsalela ezitholakala kule diphozi zinikeza imininingwane emangalisayo ngemvelo yasolwandle eyachuma eminyakeni eyizigidi ezi-3 kuya kweziyi-3.7 edlule. Phakathi nalesi sikhathi, amazinga olwandle ayephakeme kancane, futhi isimo sezulu sasifudumele, okwenza kube nesimiso esiyingqayizivele sezinto eziphilayo zasolwandle. Izinsalela zembula izinhlobonhlobo zezinhlobo zezinto eziphilayo ezivela ezindaweni ezihlukene, ezihlanganiswe ndawonye ngamagagasi namagagasi olwandle. Kusukela eminenke endala eyaziwayo yefilakisi kuya kuma- baleen whale vertebrae, le ngcebo yezinsalela iveza iwindi elihlukile ezweni elibuswa imidondoshiya ejulile, izilwane ezidla izilwane zasolwandle ezimangalisayo, kanye nezilwane ezincane eziyinkimbinkimbi ezazichuma ekujuleni.
Okutholakele okuphawulekayo
Phakathi kokutholwe okungavamile, okuningana kugqama ngokungavamile nokubaluleka kwazo. Ukutholwa kweminenke yefilakisi endala eyaziwa kakhulu kunikeza ukukhanya ngokuvela kwalawa ma-gastropod ayingqayizivele. Ngaphandle kwe-baleen whale vertebrae, okutholakele kuhlanganisa nezinye izinhlobo zezilwane zasolwandle, kuhlanganise nocezu lwezinyo le-sperm whale, nomgogodla we-sawshark engasekho. Izingcwecwe zamazinyo zemisebe yokhozi namazinyo avela koshaka abamhlophe abadumile zinezela nakakhulu ohlwini lwezinsalela ezimangalisayo ezitholakele.
Esikhumbuzweni: UDkt. Alan Beu
Lolu cwaningo lubaluleke kakhulu njengoba lunikezelwe kuDkt. Alan Beu ongasekho, uchwepheshe odumile wezinsalela ze-molluscan owashona ngeshwa ngesikhathi elungisa lezi zinsalela. Igalelo likaDkt. Beu, ulwazi, nobungcweti kube nesandla ekuqondeni nasekuhlonzeni izinhlobonhlobo zezinhlobo zezinto eziphilayo kule diphozithi. Ukuzinikela kwakhe emkhakheni we-paleontology kanye nothando lwakhe olukhulu lokwembula umlando woMhlaba ngezinsalela zamathambo kuyohlale kukhunjulwa.
Ukubambisana nokulondolozwa
Ukutholakala kwalesi sithako esicebile sezinsalela kugcizelela ukubaluleka okukhulu kokubambisana phakathi kososayensi, iziphathimandla zamanzi angcolile, nosonkontileka. Ukuhlanganiswa kwemikhakha eyahlukene kwenze ukuba kulondolozwe futhi kufundwe lezi zinsalela ezibalulekile zezinsalela. Icala lisebenza njengesibonelo esikhanyayo sokuthi imikhakha ehlukene esebenza ndawonye ingavikela kanjani izinsalela ezibalulekile phakathi nemiklamo yokwakha, iqinisekise ukuthi amarekhodi ayigugu omlando woMhlaba awalahleki unomphela ngaphansi komhlaba.
Iwindi lokubuka okwedlule kwe-New Zealand
Lokhu kutholwa okungalindelekile kunikeza ukuthuthuka okukhulu ekuqondeni kwethu umlando we-paleontological waseNew Zealand. Kwenza ososayensi bakwazi ukuhlanganisa i-akhawunti ebanzi ye-ecosystem yasolwandle eyayichuma esifundeni eminyakeni eyizigidi edlule. Ngokwandisa ulwazi lwethu lwesikhathi esidlule sase-New Zealand, sithola imininingwane emisha mayelana nemvelo yasolwandle yomhlaba wonke phakathi nenkathi ye-Late Pliocene, ekugcineni kube nesandla ekuqondeni kwethu isithombe esibanzi sokuziphendukela kwemvelo komhlaba.
Sengiphetha, lokhu okutholakele akugcizeleli nje kuphela ukubaluleka kokubambisana phakathi kwemikhakha eyahlukene kodwa futhi kwengeza ekuqondeni umhlaba wonke nge-ecosystem yasolwandle ngesikhathi se-Late Pliocene. Njengoba siqhubeka nokwembula izimfihlo zasendulo Zomhlaba, idiphozi yezinsalela zase-Auckland isebenza njengesikhumbuzo sezimangaliso ezingaphansi kwezinyawo zethu, ezilindele ukutholwa futhi zandiswe.
Ucwaningo lwashicilelwa ekuqaleni kujenali I-geology ne-Geophysics ngo-Agasti 27, i-2023.
