Makore akati apfuura, muWestern Canada, basa rokuchera migodhi rakaita kuti pave nechimwe chezvinhu zvinokosha zvikuru zvakawanwa pasi rose muyeuko yemisi ichangobva kupfuura iyi. Boka revacheri vakagumburwa netsaona pane ingangove yakanyanya kurongeka dinosaur chitunha sainzi yati yamboona.
Nodosaur, mhuka inodya ura yakanga yakareba mamita gumi nemasere uye ingangoita makirogiramu 18, yakawanikwa muna 3,000 nechikwata chaishanda mamaira 2011 kuchamhembe kweAlberta, Canada pachirongwa chekuchera migodhi. Ichi chinhu chinonakidza chakawanikwa sezvo zvisaririra zvedhinasori zvakachengetedzwa zvakanyanya; kubva kwavari, tinogona kudzidza zvakawanda pamusoro peupenyu nerufu rwedhinasori.
Masayendisiti anoti zvisaririra izvi zvinoita sekunge zvaingova nemavhiki mashoma apfuura zvisinei nekuti dinosaur yakafa makore anopfuura mamirioni zana apfuura. Izvi zvinokonzerwa nemamiriro ezvinhu akanaka kwazvo avakachengetedzwa.
Dinosaur - Borealopelta (zvinoreva kuti "nhoo yekuchamhembe") imhando ye nodosaur yakararama panguva yeCretaceous - yaive imwe yeakawanda akawana magumo ayo nekuda kwekukukurwa nemvura yemafashamo kubva murwizi sezvayaipinda. gungwa.
Nhumbi dzakakora dzakatenderedza skeleton ndiyo inokonzeresa mamiriro ayo akakwana. Yakafukidzwa kubva kumusoro kusvika kutsoka mumatairi-akaita mahwendefa uye, hongu, grey patina yematehwe efossilized.
Shawn Funk, aishanda muchina unorema muMillennium Mine, akawana zvinoshamisa apo mucheri wake wakarova chimwe chinhu chakasimba. Aiita kunge matombo eruvara rwewalnut aitove masara emupfuhwira ane makore 110 okuberekwa. Mhuka yainge yamira yainge yakamira zvekuti hafu yekumberi - kubva pamhuno kusvika muhudyu - iwanezve.
“Zvisaririra zvedhinasori zvakaparadzwa zvinoshamisa kuona,” anodaro Michael Greshko weNational Geographic.
“Zvisaririra zvedehwe zvichiri kuvhara ndiro dzine mhata dzedehenya remhuka iyi. Rutsoka rwayo rworudyi rwakagara padivi payo, manhamba ayo mashanu akatambanudzirwa kumusoro. Ndinogona kuverenga zvikero pachayo chete,” anonyora Greshko.
Nekuda kwekuvigwa kwayo nekukurumidza pasi pegungwa, dinosaur inotaridzika zvakanyanya sezvayakaita mamiriyoni emakore apfuura. Maererano nenyanzvi dzenhoroondo dzekare, idi rokuti nyama yaro haina kuora asi panzvimbo pacho yakaitwa fossilized haiwanzoitiki.
Kusiyana nehama yepedyo iyo Ankylosauridae, ma nodosaurs akange asina shin-kupatsanuka kusvika kumakirabhu. Panzvimbo pezvo, yaipfeka nhumbi dzokurwa nadzo dzakapfava kuti isarega zvikara. Iyo dinosaur yakareba mamita gumi nemasere, iyo yaigara munguva yeCretaceous, inogona kunge yakanzi rhinoceros yenguva yayo.
