TOKYO, la 17 Mots'eanong. / Corr. TLOTLISO Vasily Golovnin. Li-dinosaurs tse ling li ile tsa khona ho haha ​​lihlaha hore li qhotse bana ba tsona joalo ka linonyana. Polelo ena e entsoe ke sehlopha sa litsebi tsa paleontologists tse tsoang Univesithing ea Japane ea Nagoya motheong oa liphetho tse entsoeng China.

Bo-rasaense ba re mefuta e meng e menyenyane ea li-dinosaurs, e qhekelletse mahe feela joalo ka linonyana. Leha ho le joalo, ka nako e telele, bo-rasaense ba ne ba sa nahane hore na li-dinosaurs tsa khale tsa khale li e entse joang.

Se fumanoeng China, ho bolela Moprofesa Kokhei Tanaka, a bonts'a hore li-dinosaurs tse kholo li behela mahe sedikeng mme li lula setsing. Kahoo, ka ho khetheha, ba ne ba sireletsa bana ba ka moso ho libatana mme, kamoo ho hlakileng, ba neng ba ka sireletsa mahe a bona letsatsing.

Leha ho le joalo, ho boleloa hore mefuta e mengata ea li-dinosaur ha e hokelle mahe, empa e ile ea li tlohela kapa ea e pata ka lehlabathe le futhumetseng joalo ka likolopata.

Ka makhetlo a mabeli joalo ka linonyana

Boithuto ba morao-rao bo entsoeng ke litsebi tsa limela li boletse hore li-dinosaurs tse nyane li hlekefetsoa likhoeli tse tharo ho isa ho tse tšeletseng ka mor'a ho behela mahe. Sena se nka nako e batlang e le habeli ho feta nako ea ho tsuba ea linonyana tsa sejoale-joale, tse amanang le li-dinosaurs ke beng ka tsona ba haufi. Ntle le moo, li-dinosaurs li ne li le kholo ebile li le mali a futhumetseng, ke hore, ba ne ba hloka lijo tse ngata - ka hona, nako e telele lipakeng tsa meloko e mecha e ile ea thatafalletsa ho arabela ka potlako lefatšeng le fetohang.

Phuputsong, litsebi li hakanya hore nako e telele ea ho iketelletsa e ka beha li-dinosaurs kotsing ha setlamo se seholo sa lefats'e se ne se oela Lefatšeng lilemo tse limilione tse 66 tse fetileng. Hobane mahe a liehang ho mela nakong ea pherekano e matla ea lefatše, komello le likhohola, athe ha ho le e 'ngoe ea lintho tse phelang polaneteng ena e tsebang seo ba tla se ja hosane, monyetla o fokolang oo ba ke keng ba o hloa. 'Nete e bohloko ea bophelo, e ileng ea bapala joke e khopo le li-dinosaurs.

Bo-rasaense ba fumane joang hore ke li-dinosaurs tse ngata tse qhetsoeng mahe? Ka mokhoa o makatsang, "meheleng ea selemo le selemo" menoana (ho ba ka mokhoa o hlakileng haholoanyane, ka "letsatsi"). Meheleng ena, eo hape e bitsoang mela ea eb Ebner, e teng ho liphoofolo tsohle, ho kenyeletsa le batho. Li thehoa ka likarolo tsa dentin, tse ntlafalitsoeng letsatsi le leng le le leng. Bohareng ba bo-1990, liketane tse tšoanang li ile tsa fumanoa meno a tyrannosaurus, joale joale o ka bolela hantle hore na lenaka le leng le le leng le fumanehang lehe le hlahisitsoe joang.

Boraro ho isa ho ba tšeletseng

Ba sebelisa lisebelisoa tsa theknoloji e phahameng, bo-rasaense ba ile ba hlahloba tse ling tsa maiketsetso a li-dinosaur tse 'maloa tse fumanoeng, ho kenyelletsa le li-protocol tsa 12 protoceratops le li-dinosaur tse dinosaur tse nang le linaka tse kholo tsa kolobe, le menoana ea sejoana se seholo se dailoeng se bitsoang Hypacrosaurus stebingeri.

Ho ile ha fumaneha hore Protoceratops e ile ea ntlafala hoo e ka bang likhoeli tse tharo pele ho lefu, le Hypacrosaurus - nakong ea likhoeli tse tšeletseng. Linonyana tsa sejoale-joale nakong ea ho iphetola ha lintho li thehile leano leo ka lona li behelang mahe a mangata ka ho fetisisa ka nako e khutšoane ea ho ikhula - ho tloha matsatsing a 11 ho isa ho a 85, e leng ho eketsang haholo menyetla ea sephetho se setle.

Mosebetsi oa bo-rasaense o thatafalloa ke taba ea hore ho thata haholo ho fumana mahe a linotši tsa dinosaur. Ka hona, setšoantšo se felletseng sa hore na mefuta e fapaneng ea li-dinosaurs e qhotsitsoeng mahe ha e so khonehe. Empa ho se ho hlakile hore ho potlaka ntlheng ena ho bohlokoa ho feta ho etsa lintho ka botlalo.

Mahe a emolisitsoeng a li-dinosaurs, ho latela mefuta ea 'ona, a hatch mahe ka likhoeli tse tharo ho isa ho tse tšeletseng. Qeto ena e entsoe ke bo-rasaense ba tsoang Setsing sa Sechaba sa Sechaba sa US. Sena se tlalehiloe ke RIA Novosti mabapi le sengoloa sa mahlale koranteng ea PNAS. Bo-rasaense ba ne ba e-na le lipotso tse ngata, haholo-holo, hore na mahe a lipono tsa li-dinosaur a ile a hlaha kapele hakae.

E 'ngoe ea liphiri tsa khale ka ho fetisisa le tse kholo tsa li-dinosaurs ke hore re ne re sa tsebe letho ka nts'etsopele ea mahe a bona. Ebang mahe a tsona a kentsoe butle butle joaloka malinyane a beng ba bona ba haufi, likoena le mekholutsoane, kapa ba ne ba tšoana le litloholo tsa bona tsa sejoale-joale, linonyana tseo mahe a tsona a hōlang kapele, ”ho hlalositse Gregory Erickson oa Univesithi ea Florida e Tallahassee (USA )

Erickson o boletse hore bo-rasaense ba ithutile mahe a protoceratops le hyparchosaurs, a neng a kile a fumanoa naheng ea Argentina, Mongolia le China leboea. Tsela e ikhethang ea seo ba se fumaneng e ne e le hore mahe a ne a boloka meno a emolisitsoeng a emolisitsoeng. Bafuputsi ba ile ba tsoela pele ho feta moo - ba ile ba kuta menoana ena mme ba fumana hore ho entsoe sekhahla se secha ho bona letsatsi le leng le le leng.
Kamora ho hlahloba ka botlalo le ho bala lits'oants'o tsena, litsebi tsa limela li ile tsa tseba nako ea bophelo ba lehe le emong ka lehe. Liphetho li joalo: protoceratops - likhoeli tse tharo, hyparchosaurs - likhoeli tse tšeletseng.

Ha ba sibolla sena, bo-rasaense le bona ba tiisitse khopolo ea hore li-dinosaurs tse ling ke liphoofolo tse mali tse futhumetseng. Linakong tsa khale, li ne li qhotsa mahe, joalo ka linonyana tse phelang, empa sebopeho sa tsona se ne se le haufi le likoena, bo-rasaense ba re. Ho ile ha fumaneha hore ke li-dinosaurs feela tse ileng tsa hlaha ka potlako ho feta likoena le mekholutsoane.
