Kunja, zolengedwa zakale za prehistoric zinali zofanana ndi ng'ona, koma zinali zazikulupo: kukula kwawo kunali mamita 2-3, anali ndi khosi komanso mchira wamtambo. Nthawi yomweyo, ma dinosaurs oyamba adayenda pamiyendo inayi.
Mabwinja a Teleocrater rhadinus anakumbidwa ndi akatswiri ofukula zakale kale mu 1993. Kenako sanapereke tanthauzo, kupatula ochepa aiwo, zomwe sizinapangitse kuti aziwerenga mokwanira. Tsopano asayansi akwanitsa kupeza zowonjezera pa mafupa a dinosaur ndikupenda bwino mafupa.
Kumbukirani kuti nthawi yozizira ya 2017, ofufuza aku Germany adatsimikizira kuti zaka zisanu ndi chimodzi zamakumi asanu ndi atatu zapitazo zidatha pamdima komanso kuzizira. Malinga ndi asayansi, kufa kwa ma dinosaurs ndi 75% ya nyama zonse padziko lapansi kunachitika chifukwa cha kutsika kwakukulu kwa kutentha komanso kusowa kwa dzuwa. Zinthu zoterezi zidabuka chifukwa choti thambo lamwala linagunda dziko lathu zaka 65 miliyoni zapitazo.
Kodi ma dinosaurs adasambira bwanji?
Komabe, mu 2007, asayansi adakumbukiranso malingaliro omwe adakanidwa kale. Kenako, pamwala amwala a mumzinda wa Texas wa Glen Rose, ku Texas, pamapezeka njira zatsopano za ma dinosaur zomwe zidakhala zaka 110 miliyoni zapitazo. Monga nthawi yotsiriza, mawonekedwe awatsogoza okha adawonekera padziko lapansi, ndipo miyendo yakumbuyo mwina sizinakhudze pansi konse, kapena kuponderezetsa pang'ono. Asayansi akutsimikiza kuti zotsalira zimasiyidwa ndendende ndi ma sauropods, chifukwa m'lifupi mwake masentimita amafika masentimita 70.
Zotsatira za sauropod zopezeka ku Texas
Popeza ndizovuta kwa asayansi kulingalira momwe ma dinosaurs akuluakulu amatha kuyenda pamiyendo iwiri yakutsogolo, adatinso akusambira motere. Kupatula apo, zitha kukhala kuti, kuwoloka mitsinje ndi nyanja, ma sauropod amapumula miyendo yawo yolimba pansi ndikuchita zopanda pake, pang'onopang'ono ndikupeza liwiro? Ndipo chakuti ma dinosaurs awa sanali amphibians, kwenikweni, sizimasokoneza kukhalapo kwa lingaliro lotere. Kupatula apo, njovu zimadziwikanso ngati zolengedwa, koma izi sizimawalepheretsa kudutsa mosakhalitsa.
Ngati mukufuna nkhani za sayansi ndi ukadaulo, lembetsani ku njira yathu ya Telegraph. Pamenepo mupezapo zolengeza zatsopano za tsamba lathu!
Mwambiri, sauropods amadziwika kuti ndi amodzi osangalatsa pakuphunzira ma dinosaurs. Akatswiri a Paleontologists amakhulupirira kuti kukula kwakukulu kwa matupi awo kunawateteza kwathunthu ku zilombo, chifukwa zinali zovuta kwambiri kuvulaza cholengedwa chachikulu chotere. Koma ndi kukula kwake kwakukulu, ma sauropod nawonso adavulaza dziko lapansi, chifukwa amadya masamba ambiri. Ingoganizirani kuti nyama zoterezi zimawonekera m'nkhalango yapafupi ndikuyamba kudya mitengo - patatha milungu yochepa, mitengo ikuluikulu yokha ikadatsala mitengo.
Nkhani zam'mbuyomu
Akatswiri a GlobalWebIndex, limodzi ndi Universal Music ndi Spotify, apeza kuti ogwiritsa ntchito ambiri amamvetsera nyimbo pa intaneti. Nthawi yomweyo, 13% yokha mwa omwe amafunsidwa amamvera pomvera. Akatswiri adafunsa mafunso pafupifupi anthu 57,000 wazaka 16 mpaka 64.
Chatsopano chawonekera pa Twitter. Chochitika chaposachedwa chikutsegulira zida zapadera zomwe zimapangitsa kampani iliyonse kulembetsa pagulu lapaubwenzi kuti ipange bots kuti ikhale ndi makalata. Bot imatha kutumiza ndikulandila zidziwitso kudzera muutumiki.
Woyang'anira wamkulu wa Huawei Eric Xu adati sawona kufunika kwa ma smartwatches amakono, omwe amadzaza ndi mafoni. Adanenanso kuti ndizovuta kwambiri kuti amvetse chifukwa chake mawotchi anzeru angafunikire pomwe aliyense ali ndi mafoni, ndipo adaonjezeranso kuti iye sakadavala chida chamtunduwu. Eric Xu anena izi nthawi iliyonse.
AnTuTu yalengeza mafoni khumi ndi awiri omwe amapereka ntchito zabwino kwambiri pamitengo yawo. Kuwona kumeneku kukuwonetsa zomwe zachitika kumapeto kwa Marichi 2017. Mtsogoleri wazoyesererabe amakhalabe Lenovo Zuk Z2, yomwe ili ndi chipangizo chimodzi cha Snapdragon 820, 3 GB ya RAM ndi 32 GB ya memory flash, ndipo mtengo wake ndi $ 170. Malo achiwiri.
