AMSTERDAM, NL, April 3, 2012 - Lilemong tse fetang limilione tse 65 tse fetileng, meteor e ile ea otla leoatleng haufi le lebōpo la seo hona joale e leng Sehlekehleke sa Yucatan sa Mexico. Re tseba ka ketsahalo ena hobane ho thulana ho ile ha etsa hore ho be le ho phatloha ho hoholo ho ileng ha etsa hore lefatše lohle le be le lera la iridium.

Ka mor'a ho thulana ho ile ha tla ho timela moo li-dinosaur tsohle (ntle le linonyana) li ileng tsa nyamela. Maoatleng, li-ammonite tse hlahelletseng li ile tsa shoa, joalo ka libatana tse ngata tse kang li-plesiosaurs tse kholohali. Hoo e ka bang karolo ea 80 ho ea ho 90 lekholong ea mefuta ea lintho tse phelang metsing e ka ’na eaba e felile.

Empa haeba polanete ea ka mor'a ho thulana e ne e le lefats'e la lefu - e ne e boetse e le lefats'e la menyetla.

Lilemo tse limilione tse seng kae hamorao, mokatong o tebileng oa leoatle leo hona joale e leng toropo ea Faxe, Denmark (e ne e le nako e futhumetseng haholo lefatšeng le leoatle le phahame haholo), likorale tse ling tse ikhethang li ile tsa theha sebaka. Ba ile ba qala ho haha ​​litutulu tse neng li ntse li hola le ho ba telele ha sekete se seng le se seng se feta, qetellong ea e-ba, mekhoeng ea rōna ea kajeno ea ho nahana, lifolete tse ntle tse amohelang mefuta eohle ea bophelo ba leoatleng.

Litutulu tsa fetoha libaka tsa ho bokella. Likorale tse ling li ile tsa ikopanya le tsamaiso ena, hammoho le mefuta e meng e mengata ea lintho tse phelang metsing. Dendrophylia candelabrum e ile ea ipaka e le e babatsehang joaloka foreime ea ho haha. Nakong eo polanete e neng e bata hape 'me metsi a leoatle a theoha' me matlo ana a likorale, Metse ea pele ea Cenozoic Co-Op, a ne a siiloe a le holimo a bile a omme, mefuta e fetang 500 ea leoatle e se e itlhomme mona.

Tsoela pele ho Lekholong la rona la bo21 la lilemo. Ho chesoa ha liindasteri ka nako e telele ho thehile "mokoti o moholo ka ho fetisisa o entsoeng ke motho Denmark," ho latela mofuputsi oa Denmark Bodil Wesenberg Lauridsen oa Univesithi ea Copenhagen, ea ileng a bua le seboka sa bafuputsi ba likorale tsa metsi a batang ba neng ba bokane Amsterdam bekeng ena.

Ha bo-rasaense ba qala ho ithuta "mokoti" ona le likarolo tse ling tse haufi tsa jeoloji, ba ile ba hlokomela hore litutulu tsena tsa khale tsa likorale, tse qalileng lilemong tse limilione tse 63, ke tsa khale ka ho fetisisa tse tsejoang 'me li ka' na tsa tšoaea mohato oa pele oa mahlaseli oa sebopeho se sa tsoa ntlafatsoa sa eco.

Har’a mefuta e fumanoeng ke bo-rasaense “mohahong oa liphaposi” tsa boholo-holo ho tla fihlela joale, e mengata e ntse e tla tsejoa.

Ho feta moo, rasaense oa Denmark o ile a bolella bamameli ba hae, mesaletsa e mengata ea lintho tsa khale e ka ’na eaba e ntse e le litutulung, e emetse ho sibolloa. Libakeng tse ling, paballo ea litutulu ha ea ba ntle, empa likarolo tse ling tsa litutulu li fana ka libaka tsa bohlokoa tsa boithuto.

Na ho na le litsebi tsa paleonto ea metsing tse batlang morero?
