Kodi ndizowona kuti munthu mosavuta amachoka pa Tyrannosaurus Rex? Dispelling zikhulupiliro

Kumbukirani mmodzi wa zithunzi kwambiri wodziwika bwino mu filimu "Jurassic Park", pomwe Ellie Sattler ndi Ian Malcolm posunga Jeep, zothaŵa kuzunza Tyrannosaurus Rex? Koma kwenikweni ngati Tyrannosaurus akhoza kuwapeza ndi Jeep kuthamangitsa iye kudutsa m'nkhalango? N'zokayikitsa, amati asayansi kuchititsa phunziro latsopano.

Liwiro kayendedwe ka chilombo ndi

Kukula ndi kulemera kwa mdani ameneyu kukusonyeza kuti Tyrannosaurus sankatha kuthamanga. M'malo mwake, kayendedwe liwiro lake anali 5 m / s (18 km / h). Motero, iye osati sindinathe kukola ndi Jeep, koma ngakhale munthu amene anathawa kwa iye pa mapazi ake. Mu nkhani ina ya m'magazini a magazini ya PeerJ limanena kuti liwiro aliyense owonjezera 5 m / s, monga kuvulaza miyendo nyama.

kafukufuku

"Kutha kuthamanga Tyrannosaurus Rex (ndi zina zofanana chimphona dinosaur) akhala nkhani ya mtsutso pakati palaeontologists kwa zaka - anati wolemba utsogoleri wa phunziro, Dr. William Selers yunivesite ya Manchester. - maphunziro ambiri pogwiritsa ntchito njira zosiyanasiyana kusonyeza osiyanasiyana kwambiri akuti liwiro pazipita. Izi zikutanthauza kuti njira ayenera Itakwana akhoza kusintha Zoneneratu awa. "

nthawi ino, Dr. Ogulitsa malonda anagwirizana awiri osiyana biomechanical njira - zazikulu multidimensional kusanthula ndi kusanthula katundu chigoba molondola kwambiri yesezera changu chimene zosamukira zinyamazi chiphona. Iye anapeza kuti ngati Tyrannosaurus anayesa kuthawa, ndiye kuti mwina zinachititsa kuti fractures fupa la miyendo yake.

Chithunzi cha Tyrannosaurus Rex moyo

Zotsatira za phunziroli atsopano kulowa m'nyumba imodzi mwa yaitali paleontological mtsutso kuti zinachitika pa nkhani moyo bipedal chilombo. Kwa nthawi yaitali, asayansi anagawanika m'magulu awiri pankhani khalidwe la tyrannosaurs: ena ankanena kuti anali ogwirira ochita ankasakidwa nyama, pamene ena amakhulupirira kuti nyama zimenezi zikhoza kukhala miimba.

Ntchito atsopano a Dr. Ogulitsa malonda, zikuoneka kuti asayansi yemwe anali ndi maganizo yamasika, anali pafupi choonadi. Komanso, zokwiriridwa amakhulupirira kuti sanali khalidwe la mitundu onse khalidwe iye. Mwachitsanzo, Tyrannosaurus sanathe kusaka herbivores pang'onopang'ono ndipo nthawi yomweyo kudya zovunda.

Khalidwe la akulu ndiponso ana

Kodi kuli ngakhale kokondweretsa, n'zotheka kunena kuti kusiyana kwa khalidwe la tyrannosaurs wamng'ono ndi wamkulu. Kafukufuku akusonyeza kuti kukula kwa nyama thupi lake anakhala yaitali komanso wolemera, ndipo nthambi ndi mofanana ang'onoang'ono. Izi zikutanthauza kuti nyama wamkulu adali wolemera, pamene juveniles kunapezeka mowonjezera nimble. Komabe, ogulitsa limanena kuti kopanda izi mwina kutali ndi choonadi.
