Nguva ye Mesozoic ine nguva nhatu apo dinosaurs dzakapararira uye dzikapera. Iyi nguva mitatu ndeiyi: Triassic, Jurassic y Cretaceous. Mukati meimwe nguva pakave nekukura kukuru kwemhuka uye dinosaurs, kunyanya iyo Jurassic fauna. Nhasi tichataura nezve kusimudzira uye kuwedzerwa kwemhuka dzeCretaceous.
Kana iwe uchida kuziva zvakawanda nezvekuwedzera kwema dinosaurs uye iyo Cretaceous fauna, ichi ndicho chinyorwa chako.
Cretaceous fauna
Mumakore mamirioni makumi manomwe nemapfumbamwe akapfuura nguva iyi uye nguva mbiri dzaive nadzo, iyo Cretaceous fauna yainyanyotungamirwa kunyanya nedinosaurs. Panguva iyoyo paive nemhando dzakasiyana dzemahombekombe egungwa uye epanyika. Mukuwedzera, dzimwe hove uye zvipembenene zvinopararira. Mammam panguva iyi raive boka diki asi rakatanga kuwanda munguva inotevera.
Tichaongorora imwe neimwe mhando dzemhuka dzakagadzirwa panguva yeCretaceous.
Invertebrates
Pakati pezvose zvipuka zvakagadzirwa, kunyanya munzvimbo yegungwa, tinogona kutaura mollusks. Pakati pemollusks, maammonoid aive cephalopods akamira. Mimwe invertebrates yakazove yakapararira yaive macoleoid uye nautiloid.
Iyo phylum yemachinoderms yaive nekuwanda mukati menguva iyi. Mukati meiyi phylum tinoratidzira mamwe emhando huru dze starfish, echinoids, uye ophiuroids. Ruzivo rwese urwu rwakaunganidzwa nekuda kwemafossil deposits anozivikanwa se amber deposits. Aya masaiti ane ruzivo rukuru nezve maartropods. Izvo zvave zvichikwanisika kuwana mienzaniso yespider, shato, nyuchi, maruva, mapururufuru, masvosve, hwiza, pakati pevamwe
Vertebrates
Vertebrates zvakare aive nekukura kukuru panguva yeCretaceous nguva. Vakakurumbira mukati meboka iri vaive zvinokambaira. Mune iro reptile boka, maDinosaurs akamira ari maviri munzvimbo yakajairika yepasi uye nemugungwa mamiriro. Aya ma dinosaurs aigara pamwe chete nezvinokambaira zvegungwa nehove.
Mune zvisikwa zvepasi rese boka remhuka dzakatanga kukura zvishoma nezvishoma. Kusiyanisa kwayo kwakatanga nedzimwe mhando dzaive dzichichinja kubva kunzvimbo yekugara yegungwa. Izvi zvakaitikawo neboka reshiri.
Kukosha kwemadinosaurs mune iyo Cretaceous fauna
Sezvatakambotaura, ma dinosaurs akaumba chikamu chakakosha chemhuka dzeCretaceous. Uye ndezvekuti panguva ino, inoonekwa sezera regoridhe remadinosaurs, Vakagadzira zvese zinyoka uye zvinodya zvepanyika dinosaurs uye zvegungwa. Tichaongorora imwe neimwe yadzo.
Nyika dinosaurs
Raive riri boka rakasiyana kwazvo munguva yese iyi. Vakanga vakakamurwa kuva mapoka makuru maviri zvichienderana nedhayeti yavo. Kune rimwe divi, isu taive nema dinosaurs anodya, uye kune rimwe divi, mhuka dzinodya mhuka dzinodya mhuka dzinodya zvipuka.
Herbivorous dinosaurs
Ivo vaizivikanwawo nemazita eanithithodhodhi. Iri boka rema dinosaurs raive nechikafu chine zvirimwa chete. Mukati meiri boka tinowana zvisikwa zvakakura seizvi:
- AnkylosaursAya madinosaurs aive akakura uye dzimwe nguva aisvika kureba kwemamita manomwe uye hurefu hwemamita angangoita maviri. Ivhareji uremu hwemhando idzi hwaive matani mana. Kuzvidzivirira kubva kumhuka dzayo dzinodya, muviri wayo wakafukidzwa kana nemapfupa emabhonzo aishanda sekirasi. Ruzivo rwese urwu rwakawanikwa nekuda kwemafossil akawanikwa mukati mawo zvaikwanisa kuona kuti makumbo epamberi aive mapfupi pane ekumashure. Musoro wayo wainge wakafanana netriangle, sezvo upamhi hwaive hukuru kupfuura hurefu.
- Hadrosaurs: Aya maDinosaurs anozivikanwa zvakare semaduckbill. Ivo zvakare vaive nehukuru hukuru pakati peanenge mana uye gumi nemashanu emamita kureba. Ivo vanogona kuve nenhamba huru yemeno ekugona kugaya huswa zvakanaka. Pane dzimwe nguva fossil yakawanikwa iine shaya dzinosvika 4 mazino akarongedzwa mumitsara uye ese aive erudzi rwe molar. Mboro yakanga yakati rebei uye yakapetwa. Iko kushandiswa kukuru kwemuswe uyu kwaive kuchengetedza mwero kana uchifamba nemakumbo maviri kutiza zvikara.
- Pachycephalosaurs: Iwo aive madinosaurs mahombe ane hunhu hukuru hwaive kuve nekufambiswa kwemabhonzo kwakafananidza kunge yaive ngowani. Basa rayo guru raive rekuchengetedza. Mune mimwe mienzaniso, iyo protuberance inogona kusvika pakukora kusvika pamasentimita makumi maviri nemashanu. Yakanga iri mhando yebipedal dinosaur uye yaigona kusvika kureba kusvika pamamita mashanu uye huremu hwematani maviri, anenge.
- Ceratopsids: dinosaurs aya aive mana. Dzakanga dziine nyanga pachiso. Ivo zvakare vaive nekuwedzeredzwa kwekuseri kwemusoro kwakatambanudzirwa kumutsipa. Ivo vaive nehurefu hunosvika pamamita masere uye vakasvika kune musungwa anosvika gumi nemaviri matani.
Anofarira dinosaurs
Iwo anodya nyama anosanganisira boka rezvidhori. Aya ndiwo madinosaurs anodya ari makuru uye anomiririra zvikara zvakanyanya. Mazhinji acho aive akakura muhukuru aine makumbo akasimukira uye akasimba. Ivo vaive bipedal uye hunhu hwavo hukuru hwaive hwekuti vaive nemaviri akatarisana kumberi uye rimwe kumashure.
Pane iri boka revanodya dinosaurs zvingave zvakadaro anonyanya kuzivikanwa Tyrannosaurus Rex.
Kubhururuka zvinokambaira
Pazvisikwa zvinobhururuka zvinonyanya kuzivikanwa ndiPterosaurs. Kunyangwe akawanda achisanganisira idzi mhuka muboka rema dinosaurs, izvi hazvisizvo. Idzi mhuka dzaive dzekutanga vertebrate dzaigona kuwana kugona kubhururuka. Kukura kwayo kwaigona kusvika kusvika pamamita gumi nemaviri emapapiro.
Zvinokambaira zvegungwa
Rimwe boka rakakura zvakanyanya mumhuka dzeCretaceous dzaive zvinokambaira zvemumvura. Aiwanzo kuve akakura pakati pemamita gumi nemaviri negumi nemashanu pakureba. Ivo vaizivikanwa zvakanyanya vaive masasa uye elasmosaurids. Iyo elasmosaurids yaive nehumwe hunhu hukuru mukati mayo hwaimira nekuve nemutsipa murefu sezvo iine huwandu hwakawanda hwema vertebrae. Vainyanya kudya hove uye mamori.
Kune rimwe divi, masasaiti zvaive zvinokambaira izvo zvakagadziriswa kune hupenyu hwemugungwa. Vakanga vane muswe murefu uye wakatarisana nemupendero.
Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda pamusoro peCretaceous fauna.
