Kuziva chikamu chenhoroondo yepasi uye mhuka dzayo dzekare kunonakidza. Isu tinokudzidzisa pano zvese zvaunoda kuziva nezve mesozoic nguva, imwe yematanho apasi, kare kare vanhu vasati vavapo.
Chii chinonzi Mesozoic Era?
Nguva iyi yenhorondo yePasi yakatora makore anodarika mamiriyoni zana nemakumi masere. Iyo inozivikanwa zvakare se Zera remadinosaur.
Nguva yeMesozoic yakatanga kusvika kumakore mamiriyoni 250 apfuura. Uye yakasvika kumagumo anenge mamiriyoni makumi matanhatu emakore apfuura, nekunyangarika kweCretaceous period. Ichi chokwadi chakadzidzwa zvakanyanya ndicho chikonzero chekutsakatika kwemadinosaur.
Kana iyi Era inotanga, munhoroondo ye geological yepasi. Makondinendi ese enguva yePaleozoic akaunganidzwa mune imwe bhuroka yenyika inonzi Pangea.
Chigadzirwa chekufamba mune zvepasi crusts, Pangea yaive ichipatsanura nekukurumidza. Chii chakaburitsa kutama kunononoka, kwezvikamu zvehuwandu hwenyika iyoyo, kunzvimbo uko makondinendi aripo parizvino.
Hunhu hweMesozoic Era
Pakati peakanyanya hunhu hweiyi geological nguva, zvinotevera zvinogona kutaurwa:
- Kuonekwa uye kutsakatika kwemhuka dzinoshamisa kwazvo dzati dzamboonekwa, madhinosaurs, kwakaitika.
- Zvirimwa chikamu che chimiro chepasi pamwe chete nemvura, iyo inoumbwa nehukuru husingafungidziki. Dzaishanda sezvokudya zveshiri nemhuka dzinoyamwisa.
- Mumvura yegungwa, nhamba huru yemarudzi yakakura. Pakati pezvainyanya kukosha, pakanga pane hofori molluscs.
- Kwakanga kune mvura isingaverengeki ye<em>meteor, mukuwedzera kumabasa akawanda ekuputika kwegomo. Kukonzera kutsakatika kwemarudzi mazhinji, epasi uye emumvura.
- Pangea supercontinent yakatsemuka nekudengenyeka kwenyika. Kupa kusimudzira kumakondinendi anozivikanwa nhasi.
Nguva dzeMesozoic Era
Mesozoic Era yakakamurwa kuita nguva huru nhatu, dzinoti, dzinoti:
Triassic
Ndiyo nguva yekutanga yeMesozoic uye yakakamurwa kuita zvikamu zvitatu zvinoti:
- Kunonoka
- Pakati
- Kurumidza
Inotanga munguva ino, kusvika pakutsemuka kwePangea. Kwakanga kune kuwedzera mumabasa ekuputika kwemakomo. Mamiriro ekunze aivepo aive achidziya, izvo zvakabvumira kukura uye kuwanda kwemiti yeconiferous, ferns.
Paivawo nekukwirira kwakakosha mumatanho e Makungwa nemakungwa. Kubvumira molluscs uye bivalves kuberekana nekukurumidza. Pamwe nehove, lobster, pakati pemamwe marudzi.
Kuda kupedzisa nguva yeTriassic, kuwedzera kukuru kwesherufu yekondinendi kwakagadzirwa, muGungwa reTethys. Kukonzera kuchamhembe nekumaodzanyemba kwePangea kuumba.
Triassic dinosaurs
Iwo maArchosaurs anomira kunze kubva panguva ino, genus yeCoelophysis uye maRauisuchians zvakare akagadzirwa.
Coelophysis, dzaive mhuka dzekumhanya kukuru. Vaiva nemitsipa mirefu, mazino akapinza chaizvo, maoko avo aiva nenzwara, uye miswe yavo yaiva yakareba.
Rimwe remapoka akakosha emadinosaur aive maArchosaurs, akagadzira uye akashanduka semhuka dzinodya nyama. Asi vakaita metamorphosis, iyo yakava herbivorous mhando.
Mhuka idzi dzaiva maThecodonts, ayo akazochinjwa kuva marudzi maviri matsva, imwe yacho inonzi Phytosaurs, ine zvakawanda zvakafanana nemakarwe anhasi.
Jurassic
Inguva yechipiri ye Nguva yeMesozoic. Iyi nguva inoratidzwa nekutyoka kwePangea uye izvo zvakapa kusimudzira kune iyo makondinendi parizvino.
Iyi denderedzwa yezvidimbu zvekondinendi imwe yakatumidzwa zita rekukwira kwemvura. Kufanana neLaurasia kuchamhembe uye Gondwana, kumaodzanyemba.
Yakanga iri nguva yegoridhe, yekuwanda kwemadinosaur. Kutenda kumvura inonaya nguva dzose uye mamiriro okunze anodziya, nzvimbo dzine matanda uye zvipenyu zvakagara munzvimbo dzakapfuma zvakawedzera.
Matanho enguva yeJurassic ndeaya anotevera:
- Unhu hwakanaka
- Pakati
- mukuru
Jurassic Period Dinosaurs
Kuvandudzwa kwezvipfuyo panguva iyi kwaipfumisa zvikuru, pakanga paine budiriro huru uye marudzi makuru akagadzwa.
allosaurus
Raiva dinosaur rinotyisa, rine makumbo maviri. Kureba kwayo kwakasvika mamita masere uye kureba kwemamita matatu. Chikafu chayo chaive chekudya nyama, yaive nemakumbo mahombe ane nzara.
Brontosaurus
Inonzi dinosaur hombe panyika. Kudya kwavo kwaibva pamhando dzemiti. Vanogona kusiyaniswa nekuve nemutsipa wakareba uye makumbo akasimba.
Mhuka idzi, dzaikwanisa kusvika mamita anopfuura makumi maviri kureba, mukukura uye dzaive nehurefu hunopfuura mamita mana. Huremu hwayo hwaive pakati pematani gumi nemashanu kusvika makumi maviri.
apatosaurus
Aive madinosaur aifamba nemakumbo mana. Vaive nemutsipa murefu nemuswe, izvo zvinoonekwa seimwe yemadinosaur makuru akawanikwa. Mamwe marudzi emadinosaur aya akasvika pakureba anopfuura mamita makumi maviri nemashanu uye akanga ari mhuka dzesango.
Cretaceous
Ndiyo Cretaceous, iyo geological nguva inotanga, kana Jurassic yapera. Uye zvakare, pamwe naye Nguva yeMesozoic. Chinhu chayo chikuru ndiko kutsemuka kwePangea.
Mamiriro ekunze epanguva iyi aidziya uye aienderana nekukwira kwemakungwa. Izvo zvakaunza semugumisiro wakanaka, kuumbwa kwemakungwa emukati menyika, nemhedzisiro yekupararira kwemhuka nezvinomera.
Munguva iyi, kukura kwemarudzi emiti nemaruva, miti ine hunde dzehuni, uye nyuchi dzaigona kusvibisa maruva zvakaonekwa.
Cretaceous dinosaurs
Yakanga iri nguva yekukura kukuru kwezvipenyu zvitsva, chigadzirwa chekuda kujairana nemhoteredzo yavo itsva. Zvimwe zvacho zvakataurwa pasi apa.
Triceratops
Yakanga iri mhuka inodya uswa, vanhu vakuru vaigona kureba kupfuura 9 metres. Muviri wake waive wakasimba uye musoro wake waive muhombe.
Mhando dzeTriceratops dzakararama makore anopfuura mamirioni makumi matanhatu uye parizvino hapana masara emarango ayo akachengetedzwa.
spinosaurus
Ivo vanobva kumhuri yetheropod, mhuka idzi dzakararama mamiriyoni emakore muLower Cretaceous period. Yaive mhuka inodya uswa uye saizi yaro yaigona kunge yakakura kupfuura yeTyrannosaurus Rex.
Dehenya remhuka iyi rakafanana neremakarwe emazuva ano uye akanga akareba mamita makumi maviri.
