Moscow. 23 Loetse. INTERFAX.RU - Tlhahlobo ea setopo e fumanoang ka leboea ho naha ea Amerika ea Alaska sebakeng sa Colville River e ile ea lumella litsebi tsa limela li re li fumane mofuta oa li-dinosaurs tseo pele li neng li sa tsejoe ke saense, koranta ea Borithane ea The Guardian e tlaleha ka Laboraro.
Sengolong se phatlalalitsoeng ka Labobeli khatisong ea kotara ea paleontological ea kotara ea Acta Palaeontologica Polonica, bo-rasaense ba tsoang Univesithing ea Alaska le University ea Florida ba tlaleha hore e ne e le mabapi le ho fumana mofuta o mong oa li-hadrosaurs. Tsena ke "li-dinosaurs tse lefuoang" tse neng li ahile ka leboea ho Alaska. Mefuta e fapane haholo le masala a lelapa le le leng, a neng a kile a fumanoa Canada le karolo e kholo ea USA.
Bafuputsi ba rehetse mofuta o mocha oa Ugrunaaluk kuukpikensis, eo ka puo ea Inupiat, batho ba lulang haufi le moo ba fumanang, ho bolela "herbivore ea khale." Ona ke mofuta oa bone oa li-dinosaur o tsejoang ke mahlale, e leng tšobotsi feela ea leboea la Alaska. Boholo ba mehlala e fumanoeng ke batho ba bacha ho fihlela ho 2,7 metres ho ea fihla ho lisenthimithara tse 90. Ka nako e ts'oanang, li-hadrosaurs tsa mofuta ona li ka hola ho fihla ho limithara tse 9 ka bolelele. Meno a mangata a ile a ba lumella ho hlafuna lijo tse thata tsa semela. Ba ne ba tsamaea ka maoto le matsoho a ka morao, empa ha ho hlokahala, ba ne ba ka sebelisa maoto le matsoho a bona. Joalokaha Pat Druckenmiller oa Univesithi ea Alaska a hlokometse, "mohlape oa bacha o bolailoe ka tšohanyetso le ka nako e ts'oanang." Pele, masala a ne a hlahisoa ke li-edmontosaurs, leha ho le joalo, lipatlisiso tsa karolo e ka pele li bontšitse hore bo-rasaense ba fumane mofuta o mocha.
Ho ea ka The Guardian, ho fumana hona ho tšehetsa khopolo ea hore li-dinosaurs tse phetseng lilemong tse ka bang limilione tse 70 tse fetileng qetellong ea Cretaceous li ka ikamahanya le maemo a tlase a mocheso. Joalokaha Gregory Ericksen, moprofesa oa baeloji Univesithing ea Florida a boletse, "ho na le lefatše lohle leo re neng re sa tsebe letho ka lona." Li-hadrosaurs tsa Leboea li ka phela likhoeli tse ngata ka mocheso o tlase mme, mohlomong, le maemong a ho na lehloa. Leha ho le joalo, joalo ka Eriksen o hlokometse, "tsena e ne e se maemo a teng kajeno Arctic. Mocheso o tloaelehileng oa selemo o ne o le likhato tse 5 ho isa ho tsa 9 ho Celsius."
Ho feta moo, bo-ramahlale ba rera ho fumana hantle hore na li-hadrosaurs li ile tsa phela joang tlas'a maemo ana. Ha mohlahlami oa pokello ea nalane ea nalane ea nalane ea nalane ea nalane ea Amerika, Mark Norrell, o bolelletse The Guardian, ho ka etsahala hore, li-dinosaurs tse ka leboea li ile tsa phela bophelo bo ts'oanang le kh'outu ea sejoale-joale ea musk le moloi oa Canada oa Caribou. Ha ho na monyetla oa hore batho ba li-dinosaurs ba ne ba khona ho falla nako e telele, ho latela setsebi sa limela.
Masala a mofuta o mocha, joalo ka li-dinosaurs tse ngata tsa mesaletsa ea khale ka Alaska, li fumanoe ka bokaholimo ba mesaletsa ea Liskomb, 480 km leboea bophirima ho toropo e haufinyane ea Fairbanks le 160 km boroa ho Leoatle la Arctic. Karolo eo e rehiloe lebitso ka setsebi sa jioloji Robert Liskomb, eo ka 1961, ha a ntse a etsa lipatlisiso bakeng sa Shell, a ileng a fumana masapo a pele Alaska. Leha ho le joalo, o ne a lumela hore masapo ana ke a liphoofolo tse anyesang. Ke mashome a mabeli feela a lilemo hamorao, masapo ana a ile a bonoa e le masapo a dinosaur.
