Ma Dinosaurs ndi amodzi mwa mitundu yochititsa chidwi kwambiri m'mbiri ya kusinthika kwachilengedwe padziko lapansi. Tonsefe timadziwa bwino ma dinosaur. Kodi madinasose ankawoneka bwanji, kodi madinasos ankadya chiyani, ankasaka madinasoso bwanji, malo amene madinasoso ankakhala, komanso chifukwa chimene madinasoso anatha… Timadziwa kale zambiri zokhudza madinosaur, koma pali funso limodzi limene anthu ambiri sangamvetse kapena kuliganizira n’komwe: Kodi madinosaur anakhala ndi moyo kwa nthawi yaitali bwanji?
Akatswiri a mbiri yakale ankakhulupirira kuti chifukwa chimene madinosaur anakulirakulira kwambiri chinali chakuti anakhala ndi moyo pafupifupi zaka 100 mpaka 300. Komanso, monga ng'ona, ma dinosaurs anali nyama zokulirapo zopanda malire, zomwe zimakula pang'onopang'ono komanso mosalekeza m'miyoyo yawo yonse. Koma tsopano tikudziwa kuti sizili choncho. Madinosaur ambiri anakula mofulumira kwambiri ndipo anafa ali aang’ono.
· Kodi kuweruza moyo wa dinosaur?
Nthawi zambiri, ma dinosaur akuluakulu amakhala ndi moyo wautali. Kutalika kwa moyo wa ma dinosaur kunatsimikiziridwa pophunzira zokwiriridwa pansi zakale. Mwa kudula mafupa otsalira a dinosaur ndi kuwerengera mizere ya kukula, asayansi akhoza kuweruza zaka za dinosaur ndiyeno kulosera za moyo wa dinosaur. Tonse tikudziwa kuti msinkhu wa mtengo ukhoza kuzindikiridwa poyang'ana mphete za kukula kwake. Mofanana ndi mitengo, mafupa a dinosaur amapanganso "mphete za kukula" chaka chilichonse. Chaka chilichonse mtengo umakula, thunthu lake limakula mozungulira, lomwe limatchedwa mphete yapachaka. N'chimodzimodzinso ndi mafupa a dinosaur. Asayansi amatha kudziwa zaka za ma dinosaur pophunzira “mphete zapachaka” za mafupa a dinosaur.
Kupyolera mu njira imeneyi, akatswiri a mbiri yakale amayerekezera kuti moyo wa dinosaur yaing’ono Velociraptor unali pafupifupi zaka 10 zokha; ya Triceratops inali pafupifupi zaka 20; ndi kuti wolamulira wa dinosaur, Tyrannosaurus rex, anatenga zaka 20 kuti akule ndipo kaŵirikaŵiri ankafa ali ndi zaka zapakati pa 27 ndi 33. Carcharodontosaurus amakhala ndi moyo wa zaka zapakati pa 39 ndi 53; Madinosaur aakulu a makosi aatali, monga Brontosaurus ndi Diplodocus, amatenga zaka 30 mpaka 40 kuti akule, kotero kuti akhoza kukhala ndi moyo zaka pafupifupi 70 mpaka 100.
Utali wa moyo wa madinosaur umawoneka wosiyana kwambiri ndi momwe timaganizira. Kodi zikanatheka bwanji kuti ma dinosaur odabwitsa chonchi akhale ndi moyo wamba chonchi? Anzanu ena angafunse kuti, ndi zinthu ziti zimene zimakhudza moyo wa ma dinosaur? Kodi n’chiyani chinachititsa kuti madinosaur akhale ndi moyo zaka makumi ochepa chabe?
• Chifukwa chiyani madinosaur sanakhale ndi moyo wautali?
Chinthu choyamba chomwe chimakhudza moyo wa ma dinosaurs ndi metabolism. Nthawi zambiri, ma endotherms okhala ndi metabolism yayikulu amakhala moyo waufupi kuposa ma ectotherms omwe ali ndi metabolism yochepa. Powona izi, abwenzi anganene kuti ma dinosaurs ndi zokwawa, ndipo zokwawa ziyenera kukhala nyama zozizira zomwe zimakhala ndi moyo wautali. M'malo mwake, asayansi apeza kuti ma dinosaur ambiri ndi nyama zamagazi ofunda, motero kuchuluka kwa metabolism kunachepetsa moyo wa ma dinosaur.
Kachiwiri, chilengedwe chidakhudzanso moyo wa ma dinosaur. M’nthaŵi imene ma<em>dinosaur ankakhala, ngakhale kuti chilengedwe chinali choyenera kukhalamo ma<em>dinosaur, chinali chikhalirebe chovuta kuyerekeza ndi dziko lapansi lerolino: mpweya wopezeka m’mlengalenga, mpweya wa sulfure oxide m’mlengalenga ndi m’madzi, ndi kuchuluka kwa ma radiation ochokera m’mlengalenga. chilengedwe chonse chinali chosiyana ndi lero. Malo ankhalwe oterowo, limodzi ndi kusaka kwankhanza ndi mpikisano pakati pa madinosaur, zinapangitsa madinosaur ambiri kufa m’kanthaŵi kochepa chabe.
Zonsezi, moyo wa ma dinosaurs siutali monga momwe aliyense amaganizira. Kodi moyo wamba woterowo unalola bwanji kuti madinosaur akhale olamulira a Nyengo ya Mesozoic, kulamulira dziko lapansi kwa zaka pafupifupi 140 miliyoni? Izi zimafuna kufufuza kwina kwa akatswiri ofufuza zinthu zakale.
