Waa maxay waxa ay ahayd dinosaurs herbivorous

images of the "da'da dinosaurs" waxyoonay by filimada na ku qanciyo in tirada baaxad weyn oo mulacyada kuwanu waa carnivores. Si kastaba ha ahaatee, xitaa aqoonta aasaasiga ah ee biology, ayaa su'aal ka keenay view this. In dabiiciga ah ee maanta in ay ku quudiyaan tirada yar ee carnivores, tirada geedo daaq waa in ay ahaataa in ka badan dhawr jeer - ama bahal si fudud u dhintaan gaajo. Tusaale waxaa ah gobolka halkaas oo hoos u dadka ka mid ah noocyada herbivorous bilaabay khasaaro weyn ee bahal.

Waa lagama yaabo in xaaladda ahaa kala duwan wakhtigii mulacyada Rafaa. In kasta oo dheeraad ah oo cajiib ah in filimka u eg, tusaale ahaan, weerarka ka ilaashadaan xun, shaki kuma jiro in noocyada of dinosaurs herbivorous ahaayeen kale oo badan oo kala duwan oo ka badan Ummad ay "bulshada" habardugaagga.

Khaladaadka horyaalka

Guud ahaan, khaladaad la xiriira Dinosaurs uga haysaan. Tani ma aha la yaab leh, waxay muddo dheer ku noolaa ka hor muuqaalka kore ee Dadka, caddaymo lagu kalsoonaan karo oo ku saabsan - cilmi paleontological, si aad waajibka ku ah inay sidoo kale weli si sax ah u qeexo wixii uu arkay! Xitaa magaca cilmiyaysan ee ugu caansan (inta badan ay sabab u tahay la qiyaasi karin) oo ka mid ah dinosaurs - sauropods - ayaa la dhigay qalad. Iyada oo magaca Laatiin tarjumayaa "dinosaurs qorratada lugaha." Xaaladdan oo kale lugaha, kuwaas oo u dhaw in ay addimada xoolaha maroodiga, sidii ay ahayd mid aad u adag si ay u gudbiyaan baqtigooda - laga bilaabo 10 ilaa 40 metrik. Si kastaba ha ahaatee, magaca ku xayiran.

Xitaa magaca "herbivore" xayawaan qiroweyn ma u qalmaa wakiil kasta oo ka mid ah dubato qadiimiga ah. Laakiin Badankoodu ku kala duwan yihiin ma waxay ka dhigan tahay in yar oo size, sidaas darteed, halkii, kooxda kuwanu waxay ahaayeen drevoyadnymi, xaaladaha khatarta ah - herbivorous. Waxay cawska, halkii, xitaa ma laga yaabaa baxay sarajooggeeduna wuxuu ka xoogbadan.

Kala duwan oo ka mid ah tirada

Sida dinosaurs "dunida ku xukumi jiray" tobannaan malaayiin sano, "eyda" ee dinosaurs herbivorous siiyey kor u badan. yar - Dadka qaar dheeraad ah, qaar ka mid ah la ogaado. Cabbirka xayawaankani si weyn sidoo kale kala duwanaayeen. Xayawaan qiroweyn-cilin la odhan jiray Gesperonikus Elizabeth ahaa muddo dheer nus mitir iyo miisaamay ka yar bisad - laba kilo. In kaalinta labaad on minimalism - Compsognathus, saddex-meeloodow meter dheer oo miisaankeedu yahay saddex kiilo. Waa in la ogaadaa, si kastaba ha ahaatee, in labada "cilin" waxa loola jeedaa bahal, inkasta oo xayawaanka yaryar loo nuujiyo kala duwan.

Sababaha of gigantism iyo qoreysa dhismeedka dibadda

Laakiin wax kasta oo celcelis ahaan dinosaurs herbivorous kaliya oo kala duwan sida Joogaba, Rafaa. Tani ma aha la yaab leh, wakhtigaas waxa uu ahaa jidka surest in ay naftooda ka gardarraloowna weerar Carnivore ilaaliyo. Marka hore, marka koritaanka sida ma aha doprygnet wax ka ilaashadaan inay xubnaha muhiimka ah. Marka labaad, dabo waxay ahaayeen budad lagu kalsoonaan karo, jab iyo sidoo kale-loogu talagalay, taas oo si ammaan ah jirid gardarooday. In meel saddexaad, ee qiyaasta noocan oo kale ah, waxaa laga yaabaa in hubkiisa dheeraad ah iyo hub - .. geesihii, taarikada ilaaliya, iwm afaraad, dhammaan noocyada dinosaurs herbivorous ahaayeen xoolo daaqsinta, taas oo kordhinaysa fursadaha badbaadista ay. Si kastaba ha ahaatee, bulshaawiyiin iyo live bahal aan maanta.

Intaa waxaa dheer, geedka-cunista xayawaan qiroweyn ahaa horumar ah ee gunno ah ku daray: tallaabo guud uu ku yaalay in uu maskaxda ma madaxa, iyo in dabanicis. Qaddar yar ah "arrinta cirro" in dhaladii inta badan u adeega waayo, indhahoodu gacanta. Laakiin xudunta sacral ahaa 20 jeer ka badan oo ka masuul ah inta ka ahaa. Sidaas darteed of sauropods khilaafeen dhakada aad u yar, kaas oo la xaqiijiyey by excavations oo muujinaya images of dinosaurs herbivorous.

badnaa ee noocyada - natiijada sahayda

Seynisyahanno ku ogaaday in noocyo kala duwan oo badan oo noocyada of dinosaurs herbivorous lagu sharaxay by xaqiiqada ah in ay ma daboolaa, "aaga quudinta". Mid kasta oo ka sauropods doorbiday cuntadayda. Xitaa haddii ay sibilka on mid ka mid ah nooc ka mid ah daaqsinka, laamood qaar ka mid ah door bidayo ka treetops ah, iyo qaar ka mid ah (size kaagana) cunay koritaanka ama Fern at cagta. Waxaa intaa dheer, qaar ka mid ah dinosaurs ku cunay hal nooc oo kaliya geed, taas oo ay meesha tartanka.

The dinosaurs herbivorous ugu caansan, oo magacyadoodiina waa la yaqaan iyo xataa tan iyo carruurta, oo ku nool inta badan ee Jacka iyo muddooyinka Cretaceous. iyaga ka mid ah, Brachiosaurus, Iguanodon, Diplodocus iyo Stegosaurus. Dhamaan iyaga ka mid ah - Rafaa, laakiin in ka paleontologists kaalinta koowaad saaray Argentinosaurus. Waxay ahayd xayawaan qiroweyn warshad-cunidda ugu weyn, taas oo mararka qaarkood dhaafo miisaanka 60 tons. kaalinta labaad aado Brachiosaurus la miisaan ah 50,000 kiilo.

bahal isbeddelid

Qaybinta oo ka mid ah "ilaashadaan - xayawaan qiroweyn herbivorous", oo u dhiganta xidhiidhka ka casriga ah carnivorous iyo herbivorous, ayaa xaqiijiyay by cilmibaarisyadii cilmi Chicago, kuwaas oo lagu ogaaday in inta badan ee tselurazavrov ama ahaayeen herbivorous, ama iyaga ka soo bahal ahaan umuuruhu. Waxa ay muujinaysaa awoodda wanaagsan si ay u qabsadaan, taas oo ahayd caan ku dinosaurs ah - lama cuntada xoolaha oo ku filan, ay "tababaraa" in khudaar ah. Waxa xiiso leh in geeddi-socodka ah isbadal, kuwa badan oo iyaga ka mid ah ayaa laga badiyay ilkaha iyo ilkaha kale oo ay wejigana beddelaa dhuuban ah.

A noocyada cusub ee warshadda-cunista xayawaan qiroweyn

Waxaa u muuqan lahaa in daraasadda of sauropod ayaa socday in ka badan laba qarniyo, waa in aanu mar hore la helay oo dhan kayd ah dinosaurs on Earth. Si kastaba ha ahaatee, paleontologists weli daahfurtay la yaab leh.

saynisyahano Penn 1998 ilaa 2000, hore u helay ma ku tilmaamay xayawaan qiroweyn, taas oo la siiyey emilieae magaca Suuwassea ah. Waxaa la qiyaasayo in uu ahaa "qaraabo" Diplodocus. Cilmi, si kastaba ha ahaatee, hore u yihiin heer sare xiiso u-habeynta cagahooda sauropod, kuwaas oo loo arki karaa on lafaha, iyo sidoo kale godka la yaab leh in qalfoofka. Markii hore, godad, kuwaas oo laga helay oo dhan saddex nooc oo dinosaurs.

Sidaas daraaddeed waxaa weli waa halxidho rogeen mulacyada bakhtiyeen iyo wax go'aan ah weli saynisyahano.
