Yayiyiphi i-dinosaur yeerbivorous

Imifanekiso ephefumlelweyo yefilimu ye "dinosaur era" iyasiqinisekisa ukuba ininzi yale pangolin yayiyizilwanyana. Nangona kunjalo, nokuba nolwazi lokuqala lwe-biology lubeka ingxaki kwiingcamango. Kwiimeko zanamhlanje ukutya ukutya okuncinci, inani leerbivores limele libe ngaphezu kwamaxesha ambalwa - mhlawumbi abadliwayo baya kufa ngokulamba. Umzekelo imimandla apho, ngokunciphisa inani labantu abanomdla wezilwanyana ezinobungozi, i-mass mortality of predators yaqala.

Akunakwenzeka ukuba le meko yayihluke ngexesha lezilonda ezinkulu. Yaye nangona i-movie ibonakala yinto ephawulekayo, umzekelo, ukuhlaselwa kwesidlo esibi, akukho nto inokuthi iindidi ze-dinosaurs zeerbivorous zazininzi kakhulu kwaye zininzi kunezona "zoluntu" zezidlo.

Iimpazamo kwisihloko

Ngokubanzi, kukho ezininzi iingcamango eziphosakeleyo ezinxulumene needinosaurs. Oku akumangalisiyo: bahlala ixesha elide ngaphambi kokubonakala koluntu, ubungqina obuthembekileyo babo - uphando lwe-paleontological, ngoko emva koko, kubalulekile ukuba uchaze ngokuchanekileyo oko ubonayo! Kule igama lezesayensi lezona zidumileyo (ikakhulu ngenxa yesayizi engenakucingwa) kwezi zilwanyana - i-sauropods-sele iphosakeleyo. Ukususela kwisiLatini igama lingahunyushwa ngokuthi "ii-dinosaurs ezinemilenze yezilonda". Kule meko, ii-paws zezi zilwanyana zisondele kwimida yeendlovu, kuba kufuneka zithwale isidumbu esinzima kakhulu-ukusuka kwi-10 ukuya kuma-40 tani. Nangona kunjalo, igama liyabanjwa.

Ngona negama le "dinosaur" lingafanelanga naluphi na ummeli wezilwanyana zasendulo. Nangona kunjalo ininzi yahluke ngobunzima obungaphantsi, ngoko ke, ezi ziqhwala zaziyi-arborescens, kwi-least-herbivorous. Akwazanga ngisho nokubona utshani ekuphakameni kokukhula kwawo.

Ubuninzi bobukhulu

Ekubeni i-dinosaurs "ilawula ihlabathi" ngamashumi ezigidi zeeminyaka, "i-dinosaur ye-herbivorous" yavelisa "amaninzi". Abanye bajwayelene nabantu, abanye bangaphantsi. Ubungakanani bezi zilwanyana kwahluke kakhulu. I-dinosaur encinane egama linguHesperonikus Elizabethe lalilingumyinge weemitha elide kwaye lilinganiselwe ngaphantsi kwekati - iikhilo ezimbini. Kwindawo yesibini kwi-minimalism - i-compognat, ezintathu kwikota yeemitha ezide kunye neekhilogram ezintathu ubunzima. Kufuneka kuqatshelwe, nangona kunjalo, ukuba bobabini "iiLilliputians" bezilwanyana ezidliwayo, nangona zondla kwizilwanyana ezincinci.

Iimbangela ze-gigantism kunye neempawu zesakhiwo sangaphandle

Kodwa nayiphi na i-dinosaur yesantya ephakathi kwayo yayingefani ngokuhlukileyo. Oku akumangalisiyo: ngaloo mihla kwakuyindlela eyithembekileyo yokuzikhusela ekuhlaselweni komgwenxa wokutya. Okokuqala, ngokukhula okunjalo, akuyiyo yonke into eyenza i-predator izakuza kwizitho ezibalulekileyo. Okwesibini, imisila yabonakala ibe yintembeko engathembekiyo, impembelelo echanekileyo yezinto ezithembekileyo. Okwesithathu, ngobuninzi bobukhulu, kunokwenzeka ukuba zibe nezixhobo ezongezelelweyo kunye nezixhobo - izimpondo, iiplati zokukhusela, njl. Okwesine, zonke iintlobo zeedinosaurs zeerbivorous ziyimfuyo yezilwanyana, eyandisa amathuba abo okusinda. Nangona kunjalo, umhlambi uphila kwaye awusiyo iintshaba ezikhoyo namhlanje.

Ukongezelela, i-dinosaur ye-herbivorous ithole ibhonasi eyongezelelweyo ukusuka ekuziphendukeleni kwemvelo: i-brain ingundoqo yayisentloko yakhe, kungekhona entloko yakhe, kodwa kwintlakhram. Isixa esincinci "sombono oluhlaza" ekhanyeni sikhonze ngokuyinhloko ukulawulwa kwamehlo. Kodwa ingqondo ye-sacral yayingaphezu kwama-20 ngaphezulu kwaye yayijongene nayo yonke into. Ngenxa yoko, i-sauropods zavezwa yintaba encinci, eqinisekiswa yimifanekiso kunye nemifanekiso eqingqiweyo yeedinosaurs zeerbivorous.

Ubuninzi beentlobo bubangelwa sisondlo

Iingcali zenzululwazi ziye zaqinisekisa ukuba iintlobo ezininzi zeentlobo ze-dinosaurs ezithandwayo zibangelwa into yokuba "ayinayo" indawo yokutya. Ngamanye ama-sauropod akhetha ukutya kwabo. Nangona babedla ngolunye uhlobo lwezityalo, omnye umntu wakhetha amagatsha avela phezulu kwimithi, kwaye omnye umntu (ubukhulu becala kakhulu) wayidla i-fern okanye i-fern ngenyawo. Ngaphezu koko, ezinye iidinosaurs zitya enye yeentlobo zemithi, eyayilawula ngokupheleleyo ukhuphiswano.

Iidinosaurs ezidumileyo ezidumileyo, amagama abo awaziwayo nakubantwana, ahlala kakhulu kwiiJurassic naseCretaceous. Phakathi kwabo yi-brachiosaurus, iguanodon, diplodocus kunye ne-stegosaurus. Zonke ziyiziqhwala, kodwa kwindawo yokuqala i-paleontologists ziye zanikeza i-argentinosaurus. Kwakuyiyona dinosaur enkulu kunazo zonke ezithandwayo, ngezinye izihlandlo ezingaphezulu kweetoni ezili-60. Indawo yesibini ibanjwe i-brachiosaurus enesisindo sama-50,000 kilogram.

Ukuguqulwa kwezilwanyana

Ukuhanjiswa kwe "dinosaur" ye-predator - herbivorous herinovorous, ehambelana nomlinganiselo wamanqaku omhla wokutya kunye neerbivorous, uqinisekiswa yizinto ezifunyenweyo ze-Chicago ososayensi abaye baqinisekisa ukuba uninzi lwama-ceulurasaurs lwaluyinkomo yakhe, okanye yavela kuye evela kwizilwanyana. Oku kubonakalisa ukulungelelaniswa kakuhle, okwakunemveli kwiidinosaurs - baqala ukungabikho kokutya kwezilwanyana, "bahlaziywa" kwindawo yokutya yemifuno. Kuyathakazelisa ukuba ngexesha lokuguqulwa kwabaninzi balahlekelwa yimfumbo kunye namanye amazinyo, kwaye i-muzzle yabo yaguqulwa yaba yintonga.

Iintlobo ezintsha ze-dinosaur ezinomdla

Kubonakala ngathi ukufundwa kweeuropods kuye kwaqhubeka iminyaka engaphezu kweyesibini, kufuneka ukuba sele ifunyenwe yonke idipozithi ze-dinosaurs emhlabeni. Nangona kunjalo, i-paleontologists isamangalisa ngokufumanisa.

Inzululwazi yasePennsylvania ukusuka ngo-1998 ukuya ku-2000 yafumana i-dinosaur engaziwayo, eyayibizwa ngeSuwassea emilieae. Kucingwa ukuba wayeyi-diploma "isihlobo". Abaphandi, nangona kunjalo, sele benomdla kakhulu ekuguquleni imilenze ye-sauropod, ebonakalayo emathanjeni, kunye nengxuma engaqondakaliyo ekhanda. Ngaphambili, ezo zimbobo zafunyanwa kuphela kwiintlobo ezintathu zeedinosaurs.

Ngako-ke kusekho izibambiso ezibangelwa zizilwanyana ezingapheliyo kwaye zingasombulululwa yizinzulu.
