Dinosaur Jurassic nezinye izilwane Jurassic. Umhlaba Jurassic (ifotho)

Iplanethi yethu eminyakeni ayizigidi zezinkulungwane ezimbalwa ubudala, futhi indoda ebonakala kuso hhayi isikhathi eside kakhulu edlule. A kwezigidi ezingu edlule Umhlaba yayibuswa isidalwa ezahlukene kakhulu - onamandla, fast and okukhulu. Yiqiniso, sikhuluma izibankwakazi ayehlala cishe bonke ubuso iplanethi emakhulwini eminyaka adlule. Isibalo zinhlobo kwalezi zilwane libanzi, futhi ngokuqiniseka singasho ukuthi izibankwakazi kanye Jurassic Umhlaba sisonke kwakungamadodana onhlobonhlobo. Futhi esikhathini esinikeziwe kungase kubhekwe njengokwelapha impilo elichumayo we yezimila nezilwane ezihlukahlukene.

ukuphila yonke indawo

Isikhathi Jurassic kwaba iminyaka eyizigidi 200-150 edlule. Ngokokuqala isici sezulu ngokwanele ashisayo. izimila Okuwugqinsi, ukungabi iqhwa kubanda uholé yokuthi ukuphila emhlabeni kwaba yonke indawo: emhlabathini, umoya emanzini. umswakama high kuholele ekhephuzelayo ekukhuleni kwesihlahla nasekuvezeni izithombo, okuyinto eyaba ezidla uhlaza ukudla kumile ukuze osayizi omkhulu. Kodwa, kanye nezilwane ezincane wakhonza njengephayona ukudla ezizingelayo, ezihlukahlukene okuyizinto ngempela ezithakazelisayo.

Umhlaba amazinga andle were kuphakame kakhulu kunalokho manje, kanye nesimo sezulu-nobungane kwaholela ekubeni ezihlukahlukene ocebile ukuphila emanzini. Shoal eziphehliwe mollusk nezilwane ezincane, okuyinto zibe ngukudla ezinkulu ezizingelayo zasolwandle. Ayikho ngaphansi lwalunamandla impilo futhi emoyeni. Flying izibankwakazi kwesikhathi Jurassic - pterosaurs - supremacy isibhakabhaka lithunjwa. Kodwa esikhathini esifanayo babe amadlozi wezinyoni zanamuhla, amaphiko ezazingekho lesikhumba webs nezimpaphe eqale.

izibankwakazi herbivorous

Inkathi isikhathi Jurassic wanika emhlabeni ezihuquzelayo eziningi ezinkulu. Iningi labo liye lifinyelele ngezabelo kumnandi omkhulu. Umhlangano omkhulu kunayo yonke dinosaur Jurassic - Diplodocus, abahlala endaweni yesimanje United States, kwanyatheliswa ubude 30 amamitha futhi zinesisindo esingaphezu kwamathani cishe 10. Kuyinto ephawulekayo ukuthi isilwane odla ukudla isitshalo hhayi kuphela, kodwa amatshe. Kwakudingekile ukuqinisekisa ukuthi amatshe amancane kwakugaywa izimila amagxolo omuthi esiswini sesilwane. Ngemva Diplodocus namazinyo zisezincane kakhulu, hhayi ningi than uzipho womuntu, futhi ayikwazanga uyisize imfuyo kahle ukuhlafuna on ukudla isitshalo.

Okungenani Brachiosaurus enkulu ibe nesisindo ngaphezu kwamaminithi isisindo izindlovu 10, futhi ifinyelela amamitha 30 ukuphakama. Lesi silwane wahlala ezweni namuhla elibizwa Afrika futhi udla amaqabunga AmaConifers futhi cycads. giant okunjalo esikuthola kalula cishe isigamu tonne ukudla isitshalo ngosuku futhi uncamela ahlala eduze kwamanzi.

Ummeleli ezithakazelisayo ezidla uhlaza wangaleyo nkathi - kentrosaurus - wahlala endaweni manje ebizwa ngokuthi Tanzania. Lokhu dinosaur kwesikhathi Jurassic wayenesithakazelo isakhiwo umzimba wabo. On ngemuva yezilwane yayimane ipuleti esikhulu, nomsila embozwe spikes enkulu ezisiza ekulweni eziyingozi. Isilwane kwaba mayelana 2 metres ubude kanye ubude 4.5 amamitha. Kentrosaurus ulesisindo cishe isigamu ton, okwenza kube dinosaur ezihambayo kakhulu.

izibankwakazi ezidla Jurassic

A ezihlukahlukene ezidla uhlaza futhi kuholela inqwaba ezizingelayo, ngoba imvelo igcina ibhalansi njalo. I-dinosaur ngobukhulu futhi womele igazi kakhulu kwesikhathi Jurassic - Allosaurus, safinyelela ubude cishe 11 metres, lokuphakama kwakuzingalo 4 amamitha. Lokhu umhlaseli nge isisindo amathani 2 ezingelwa endaweni yase-United States futhi Portugal, wathola isicoco of igijima. Ngidle nje kuphela ukuhlasela izilwane ezincane, kodwa yokuxhuma iqembu ezingelwa ngisho inyamazane enkulu kakhulu, ezifana Apatosaurus noma Camarasaurus. Ngenxa yalesi nesineke, noma imizamo abasha ngabanye ngokuhlanganyela kwawona amathole enkomo, ke, ushwabadelwe bebonke.

Akwaziwa Dilophosaurus ngokwanele, ophilayo ensimini ka Melika yesimanje, ukufinyelela ngamamitha amathathu ukuphakama futhi nesisindo esingaba amakhilogremu angu-400. nomzingeli Quick nge emikhulu isici ekhanda, ngokwanele omele elikhanyayo kwesikhathi, afana tyrannosaurs. Mina ezingelwa izibankwakazi encane, kodwa i-pair noma iphakethe kungaba ukuhlasela futhi isilwane kuningi kunokomuntu lingakanani. maneuverability Greater nesivinini avunyelwe Dilophosaurus ukubamba ngisho fast ngokwanele futhi scutellosaurus yesikhumbuzo.

izilwane zasolwandle

Land - akuyona indawo kuphela ayakhe izibankwakazi, nezwe kwesikhathi Jurassic emanzini wayebuye ahlukahlukene futhi enezici. Ummeleli okhazimulayo wangaleyo nkathi kwaba plesiosaur. Lokhu natatorial okuzingela isibankwa entanyeni obuphelele ifinyelele ubude 18 amamitha. isakhiwo lwamathambo nge short kodwa ebanzi ngokwanele kanye nomsila onamandla amaphiko efana amaphini ukuvumela lolu umhlaseli ukuthuthukisa ngejubane elikhulu futhi unqobe ekujuleni kolwandle.

dinosaur ezingengaphansi ezithakazelisayo zasolwandle kwesikhathi Jurassic - ichthyosaur, efana amahlengethwa yesimanje. engavamile laso laba ukuthi, ngokungafani nezinye izibankwakazi, lokhu nomzingeli ubethula kodwa izala izinhlanzi eziphilayo kunokuba amaqanda. Ichthyosaur safinyelela 15 metres ubude ezingelwa inyamazane ezincane.

amakhosi esibhakabhakeni

Ekupheleni kwesikhathi Jurassic, ezindaweni eziphakeme wasezulwini ngilinqobile encane izilwane ezidla ezinye pterodactyls. Namaphiko isilwane ifinyelele imitha elilodwa. umzimba nomzingeli wawumncane futhi akazange idlule isigamu imitha, isisindo omdala ifinyelela 2 ngamakhilogremu. Khumula nomzingeli kabakubonanga, ngaphambi ababeya indiza, kwakudingeka aqwale edwaleni noma unqenqema. Pterodactyl sidle inhlanzi, okungase ukubona ibanga elithileko. Kodwa ngezinye izikhathi waba isisulu izilwane ezidla ezinye, ngoba babona ukuthi le ndawo ngempela kancane futhi zizimbi.

Esinye Ummeleli we Dinosaurs flying kwaba rhamphorhynchus. Kancane ngaphezu pterodactyl, lokhu nomzingeli kuhlaziywe amakhilogremu amathathu kwadingeka namaphiko ngamamitha amabili. Habitat - eYurophu Ephakathi. I engavamile walesi dinosaur ezinamaphiko waba umsila omude. namazinyo Cijela nemihlathi enamandla ukuvumela ukubamba ukukhiqizwa eshelelelayo ezimanzi, futhi ngesisekelo ekudleni kwemfuyo kwakungu inhlanzi, izimbaza, okumangalisayo pterodactyls encane.

izwe Ukuhlala

Izwe ngaleso iziteleka isikhathi by ukwehlukana kwayo: hhayi kuphela labantu emhlabeni ngesikhathi babe izibankwakazi. Futhi izilwane eziphilayo zenyama kwesikhathi Jurassic, omunye amakilasi zazivame. Yingaleso sikhathi-ke, sibonga izimo ezinhle, kwakukhona izimfudu ngesimo esiphila manje ajwayelekile. Lyagushkoobraznye ezihuquzelayo ezifuywa, zibe ngukudla izibankwakazi encane.

Pacific nasolwandle kwakuphithizela ezihlukahlukene kwezinhlobo zezinhlanzi, ezifana oshaka, imisebe nezinye cartilaginous futhi bony. Cephalopods, nabo belemnites, babe isixhumanisi aphansi e eziwukudla, kodwa labantu Polynomial asekelwe ukuphila emzimbeni yamanzi. Phakathi nale nkathi, kukhona ezinamagobolondo ezifana barnacles, listonogie futhi decapods, kanye angenasawoti neziponji.

Lesisemkhatsini

Jurassic ukuvela emangalisayo yokhokho wezinyoni. Yiqiniso, lwatholakala kuyi-archaeopteryx wayengekho kakhulu efana izinyoni yesimanje, kwathiwa kunalokho miniraptor ngezimpaphe. Kodwa ukhokho kamuva, ubizwa longipteriks kakade owawufana ivuba yesimanje. Nakuba izinyoni ngoba isikhathi futhi zithandwa ezingavamile, kodwa ukuthi zisenza sibe esiyindilinga entsha kwemvelo emhlabeni isilwane. Sekuyisikhathi eside Dinosaurs kwesikhathi Jurassic (isithombe oboniswe ngenhla) kwaba yokuqothulwa, kodwa manje, ubuka izinsalela imidondoshiya, wema ukwesabe kulezi zintaba.
