Dinosaurs ndeimwe yezvisikwa zvepakutanga zvePasi, zvichionekwa munguva yeTriassic makore mamiriyoni 230 apfuura uye yakatarisana nekuparara munguva yeLate Cretaceous makore mamiriyoni 66 apfuura. Nguva yedinosaur inozivikanwa se "Mesozoic Era" uye yakakamurwa kuita nguva nhatu: Triassic, Jurassic, uye Cretaceous.
Triassic Period (makore 230-201 mamiriyoni apfuura)
Nguva yeTriassic ndiyo nguva yekutanga uye yakapfupika yenguva yedinosaur, inogara makore angangoita mamirioni makumi maviri nemapfumbamwe. Mamiriro okunze ePasi panguva iyi akanga asina kuoma, mwero wegungwa wakanga wakaderera, uye nzvimbo dzapasi dzakanga dziri duku. Pakuvamba kwenguva yeTriassic, ma<em>dinosaur aingova zvipuka zvakajairika, zvakafanana nengwena namadzvinyu emazuva ano. Nokufamba kwenguva, mamwe madhinosaur zvishoma nezvishoma akava makuru, akadai seCoelophysis uye Dilophosaurus.
Jurassic Period (makore 201-145 mamiriyoni apfuura)
Nguva yeJurassic ndiyo yechipiri nguva yenguva yedinosaur uye imwe yeanonyanya kufarirwa. Munguva iyi, mamiriro ekunze ePasi akava nekudziya uye kunyorova, nzvimbo dzepasi dzakawedzera, uye mazinga egungwa akawedzera. Paiva nemhando dzakasiyana-siyana dzemadinosaurs akararama panguva iyi, kusanganisira mhuka dzinozivikanwa seVelociraptor, Brachiosaurus, uye Stegosaurus.
Cretaceous Period (makore 145-66 emakore apfuura)
Nguva yeCretaceous ndiyo yekupedzisira uye yakareba nguva yedinosaur nguva, inogara makore anenge mamiriyoni makumi masere. Munguva iyi, mamiriro ekunze ePasi akaramba achidziya, nzvimbo dzepasi dzakawedzera, uye mhuka huru dzemugungwa dzakaonekwa mumakungwa. MaDinosaurs panguva iyi aivewo akasiyana zvakanyanya, kusanganisira zvisikwa zvine mukurumbira zvakaita seTyrannosaurus Rex, Triceratops, uye Ankylosaurus.
Nguva yedinosaur yakakamurwa kuita nguva nhatu: Triassic, Jurassic, uye Cretaceous. Imwe neimwe nguva ine yakasarudzika nharaunda uye inomiririra dinosaurs. Nguva yeTriassic ndiyo yakatanga kushanduka kwemadhinosaur, nemadinosaur zvishoma nezvishoma achiwedzera kusimba; nguva yeJurassic yakanga iri peak yenguva yemadhinosaur, nemarudzi akawanda ane mukurumbira achionekwa; uye nguva yeCretaceous yaive magumo enguva yedhinaso uye zvakare nguva yakasiyana-siyana. Kuvapo uye kutsakatika kwemadinosaur aya kunopa chirevo chakakosha chekudzidza kushanduka kwehupenyu uye nhoroondo yePasi.
