Nakuba ama-dinosaurs eyizinhlobo ezashabalala ngokuphelele, kube nokwenzeka ukuba kukhishwe ulwazi oluhle ngawo ngenxa yamarekhodi ahlukahlukene wezinsalela. Namuhla sizokhuluma ngakho I-Brontosaurus. Idayinaso engenye eyaziwa kakhulu namuhla. Iyingxenye yeqembu lama-sauropods ayingxenye ye-Diplodocidae. Igama laso livela kuLatini futhi kufanele lisho isibankwa sokuduma. Leli gama libhekisela ekubukekeni kwayo.
Kulesi sihloko sizokutshela zonke izici, indawo yokuhlala, ukudla kanye nezinto ezikhangayo ze-Brontosaurus.
Izici eziyinhloko
Iwuhlobo lwedayinaso ubude balo phakathi kwamamitha angu-20 no-25 ubude. Babekwazi ngisho nesisindo esingaphezu kwamathani ayi-15 ngokuba nalo sayizi nesisindo. Yathuthukiswa ngesikhathi se-Upper Jurassic. Lokhu cishe eminyakeni eyizigidi ezingu-150 edlule. Itholwe endaweni yase-United States. Njengoba ifana kakhulu ne-Apatosaurus, ayizange ithathwe njenge-Brontosaurus futhi ibizwe I-Apatosaurus excelsus. Sekuvele kamuva ngonyaka wezi-2015 lapho ucwaningo olunemininingwane eminingi lwethulwa ngocwaningo olukhulu emuva ukuze luphinde lubhekwe njengeBrontosaurus.
Ingenye yezilwane ezinkulu kunazo zonke ezike zahlala emhlabeni wonke endaweni yethu. Bekungenye yama-quadruped amakhulu kunawo wonke ake aba khona. Yayibizwa ngegama lika- ukuduma kwezulu kwazise umhlaba wawunyakaza uma uhamba ngenxa yesisindo sawo. Imilenze yayinesisindo esingaphezu kwamakhilogremu angu-200 ngayinye yayo njengoba yayidinga izitho eziqinile ukuze ikwazi ukuthwala sonke isisindo somzimba uwonke. Yaziwa ngokuba nentamo nomsila omude ukuze ikwazi ukumelana nokuzinzisa ukuma. Umsila wayo wawumise okwesiswebhu futhi wawusiza hhayi nje kuphela ukuthi uhlale uzinzile, kodwa nokuzivikela ezitheni zayo.
Kwakungezona izilwane ezihlakaniphile kodwa zakwazi ukuphila isikhathi eside ngenxa yobukhulu bazo obukhulu kanye nokujwayela kwazo ngokomzimba. Imilenze yayo yangemuva yayiyinde kancane kunemilenze yangaphambili, nakuba zingakatholakali izinsalela ze-neon ezitholakalayo ukuyicwaninga. Kucatshangelwa ukuthi kuyafana nalokhu I-Apatosaurus Louisae enamathambo omgogodla nhlangothi zombili. Lawa ma-vertebrae asebenza ukugcina intamo ibe yinde futhi ibanzi. Lezi zici zijwayelekile eqenjini le-sauropod. Nakuba umsila wayo wawumude kodwa wawuzacile. Izimbambo zazizinde futhi zazinamathambo aqinile nezitho.
Okuthile okwakugqanyiswa yimilenze yayo. Babenozipho olulodwa kuphela lwangaphambili. Futhi wukuthi abazange basebenzise imilenze yabo ukuze bazivikele njengoba babesindwa kakhulu. Engxenyeni yezinhlamvu babeneziphopho ezakheke eminwe emithathu.
Ukuhlukaniswa nokuhlukaniswa kwe-Brontosaurus
Emandulo Ama-Sauropods ayecatshangwa njengezilwane ezinkulu kangangokuthi ayengakwazi ukusekela isisindo sazo. Lesi yisizathu esenza ukuthi kucatshangwe ukuthi indawo yabo yemvelo yayiyizindawo lapho babengacwiliswa khona noma ngamanzi. Isibonelo, emaxhaphozini angacwiliswa emanzini ukuze asekele kangcono isisindo sawo ngenxa yokuminyana kwamanzi. Kodwa-ke, ngemva kokutholwa okuningana okuvela ezifundweni ezalandela, lobu bufakazi buye balahlwa futhi kukholakala ukuthi kwakuyizilwane zasemhlabeni ngokuphelele.
Izintamo zabo ezinde zaziwavumela ukuba athathe ukudla ezihlahleni ezinde kakhulu. Kwezinye izimo, kuye kwashiwo izizathu ezenza kube nokwenzeka ukwazi ukuthi kwakungenakwenzeka ukuhambisa intamo kalula. Nokho, kamuva kwaziwa ukuthi zazinezintamo eziguquguqukayo kakhulu. Kucatshangwa nokuthi kwakuyizilwane ezikwazi ukugijima phakathi kwamakhilomitha angu-20 no-40 ngosuku, zibalekela ukufinyelela isivinini esingamakhilomitha angu-30 ngehora. Lokhu akuwenzi umqondo omkhulu ukwazi lokho Zinesisindo esingamathani angu-15 kodwa njengoba zizikhudlwana, zahamba ibanga ngesivinini esisheshayo.
Babengenayo imisipha eminingi futhi nokunyathela kwabo kwakungaphumeleli kakhulu uma kubhekwa isisindo sabo. Ngakho-ke, ayengewona ama-dinosaurs asheshayo ayekhona. Uzipho ababenalo engxenyeni engaphambili yomlenze kucatshangwa ukuthi ngezokuzivikela, nakuba bebelusebenzisela ukuphakela. Kwasetshenziswa ukuvikela umsila.
I-Brontosaurus yokudla
Mayelana nokudla, kubalulekile ukuqaphela ukuthi ukudla kwakucatshangwa ukuthi kubi kakhulu ekuqaleni. Nokho, uphenyo oluhlukahlukene lwenziwa nezazi ze-paleontologists zaseJalimane kwakungenzeka ukwazi ukuthi amathumbu anobukhulu obukhulu ukuze akwazi ukucubungula konke ukudla. Idla ikakhulukazi izihlahla ezihlala ziluhlaza kanye nama-ferns ukuze zakhe ukudla okunomsoco. Kwakuyizilwane ezidla utshani. Kwezinye izimo, izibonelo ziye zatholakala ukuthi Ayedlula amamitha angu-40 ubude futhi anesisindo samathani ayi-100.
Ezigidini zeminyaka edlule, phakathi nesikhathi lapho kwakuhlala khona i-Brontosaurus, kwakunenqwaba yezihlahla zeqembu lama-conifers, ama-fern nezinye izitshalo ezinezici ezifanayo. Futhi kungenxa yokuthi izimbali zamanje zazingakasakazeki emhlabeni wonke. Ngakho, ukudla kwe-Brontosaurus kusekelwe ikakhulukazi kulolu hlobo lwemifino. Siyazi ukuthi okwamanje azikho izilwane ezidla lezi zihlahla, yingakho zingathathwa njengomthombo wokudla. Nokho, ngenxa yocwaningo nokuklanywa kwamathumbu enziwe ngokwenziwa, kwakungenzeka ukuthola ukuthi ayizitshalo ezinomsoco ngempela.
Ngokutholwa okusha kwakwaziwa ukuthi ama-conifers nama-fern anganikeza cishe amandla afanayo noma ngisho nangaphezu kotshani bamanje. Lezi zilwane zakwazi ukusinda futhi zafinyelela ubukhulu obukhulu ngenxa yokuthi zazichitha usuku lonke zidla. Ngaleso sikhathi kwakuyizo zodwa ukudla okwakukhona. Ososayensi bacabanga ukuthi i-metabolism ye-Brontosaurus ifana kakhulu neyendlovu yesimanje. Njengoba ayekhuluphele, kwakudingeka adle inani lendlovu eliphindwe ngo-4. Ezilwaneni zamanje lokhu kungase kusho inkinga, kodwa hhayi ku-Brontosaurus, ngoba abazange bakuhlafune ukudla kwabo. Yile ndlela ayekwazi ngayo ukudla inani elikhulu.
Indawo nendawo okusatshalaliswa kuyo
Lezi zilwane kucatshangwa ukuthi zaziphila mayelana cishe eminyakeni eyizigidi eziyi-150 edlule, ikakhulukazi ngesikhathi seJurassic ephezulur. Endaweni lapho zathuthukiswa khona kwakuseNyakatho Melika, ikakhulukazi ekubunjweni kukaMorrison.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi nge-Brontosaurus nezici zayo.
