AMSTERDAM, NL, Kubvumbi 3, 2012 - Makore anopfuura miriyoni makumi matanhatu neshanu apfuura, meteor yakarova mugungwa pedyo nemhenderekedzo yezvino yava Mexico's Yucatan Peninsula. Isu tinoziva nezve chiitiko ichi nekuti kudhumhana kwakagadzira kuputika kwesimba kwakaisa pasi pasi rose tattle-tale layer ye iridium.

Kutevera kubonderana kwakauya kutsakatika umo madhinosaur ose (kunze kweshiri) akanyangarika. Mumakungwa, maammonites ane simba akafa, sezvakaita zvikara zvakawanda zvikuru sema super-huge plesiosaurs. Zvinenge 80 kusvika ku90 muzana zvezvipenyu zvomugungwa zvingave zvakatsakatika.

Asi kana pasi-pashure pekudhumhana yaive nyika yerufu - yaivewo nyika yemukana.

Mamirioni mashoma emakore gare gare, pauriri hwegungwa rakadzika rezvino dhorobha reFaxe, Denmark (yakanga iri nguva inodziya kwazvo panyika uye mazinga egungwa aive akakwira zvakanyanya), mamwe makorari akasarudzika akamisa nzvimbo. Vakatanga kuvaka mirwi yaikura nekureba nemireniyamu yega yega yaipfuura, pakupedzisira vachiva, kumafungiro edu emazuva ano, dzimba dzemafurati dzakanakisa dzaigamuchira marudzi ese ezvipenyu zvemugungwa.

Mirwi yakava nzvimbo dzekuunganidzira. Mamwe makorari akabatana nehurongwa, pamwe chete nemamwe marudzi mazhinji ezvipenyu zvemugungwa. Dendrophylia candelabrum yakaratidza kuva yakanaka kwazvo sefuremu yekuvaka. Panguva iyo pasi payakatanga kutonhora zvakare uye mvura yegungwa yakadzikira uye idzi dzimba dzemafurati emakorari, aya ekutanga eCenozoic Co-Op Cities, akasiiwa akakwirira uye akaoma, anopfuura 500 emhando dzemugungwa dzakasiyana dzakazvisimbisa pano.

Flash-mberi kune yedu 21st Century. Kuchera maindasitiri kwenguva refu kwakagadzira "gomba rakakura kwazvo rakagadzirwa nevanhu muDenmark," sekureva kwemuongorori weDanish Bodil Wesenberg Lauridsen weYunivhesiti yeCopenhagen, akataura kumusangano wevaongorori vemvura inotonhora vakaungana muAmsterdam svondo rino.

Masayendisiti paakatanga kudzidza "gomba" iri uye zvimwe zvimiro zve geological zviri pedyo, vakaziva kuti aya maturu ekare emakorari, ekare makore 63 miriyoni, ndiwo ekare anozivikanwa uye anogona kunyatso ratidza danho rekutanga remwaranzi reiyo ichangobva kushanduka eco-chimiro.

Pamarudzi akawanikwa nemasayendisiti mu“furati” yekare kusvika nhasi, akawanda acho haasati azivikanwa.

Uyezve, musayendisiti weDanish akaudza vateereri vake, mamwe mafossils akawanda anogona kunge achiri mumirwi, akamirira kuwanikwa. Mune dzimwe nzvimbo, kuchengetedzwa kwezvikomo kwave kusina kunaka, asi zvimwe zvikamu zvezvikomo zvinopa nzvimbo dzepamusoro dzekudzidza.

Chero marine paleontologists ari kutsvaga chirongwa?
