MaDinosaur ndeimwe yemhuka dzemusana dzakatanga panyika, dzakaonekwa munguva yeTriassic makore angangoita mamiriyoni mazana maviri nemakumi matatu apfuura uye dzakatarisana nekutsakatika munguva yeLate Cretaceous makore angangoita mamiriyoni makumi matanhatu nematanhatu apfuura. Nguva yemaDinosaur inozivikanwa se "Mesozoic Era" uye yakakamurwa kuita nguva nhatu: Triassic, Jurassic, uye Cretaceous.
Nguva yeTriassic (makore mamiriyoni 230-201 apfuura)
Nguva yeTriassic ndiyo nguva yekutanga uye pfupi yenguva yemadinosaur, inotora makore angangoita mamiriyoni makumi maviri nemapfumbamwe. Mamiriro ekunze panyika panguva iyi aive akaoma, mwero wegungwa wakaderera, uye nzvimbo dzepasi dzaive diki. Pakutanga kwenguva yeTriassic, madinosaur aingova zvinokambaira zvakajairika, zvakafanana nemakarwe nemadzvinyu emazuva ano. Nekufamba kwenguva, mamwe madinosaur akatanga kukura zvishoma nezvishoma, akadai seCoelophysis neDilophosaurus.
Nguva yeJurassic (makore mamiriyoni 201-145 apfuura)
Nguva yeJurassic ndiyo nguva yechipiri yenguva yemadinosaur uye imwe yedzakakurumbira. Munguva iyi, mamiriro ekunze ePasi akava ekudziya uye ane hunyoro, nzvimbo dzepanyika dzakawedzera, uye mwero wegungwa wakawedzera. Kwaiva nemarudzi akasiyana-siyana emadinosaur akararama munguva iyi, kusanganisira marudzi anozivikanwa akadai seVelociraptor, Brachiosaurus, naStegosaurus.
Nguva yeCretaceous (makore mamiriyoni 145-66 apfuura)
Nguva yeCretaceous ndiyo nguva yekupedzisira uye yakareba kwazvo yenguva yemadinosaur, inotora makore angangoita mamiriyoni makumi masere. Munguva iyi, mamiriro ekunze ePasi akaramba achidziya, nzvimbo dzepanyika dzakawedzera, uye mhuka hombe dzemugungwa dzakaonekwa mumakungwa. Madinosaur munguva iyi aive akasiyana-siyana, kusanganisira mhando dzakakurumbira dzakadai seTyrannosaurus Rex, Triceratops, uye Ankylosaurus.
Nguva yemadinosaur yakakamurwa kuita nguva nhatu: Triassic, Jurassic, uye Cretaceous. Nguva imwe neimwe ine nharaunda yayo yakasiyana uye madinosaur anomiririra. Nguva yeTriassic ndiyo yakatanga kushanduka kwemadinosaur, madinosaur achiramba akasimba zvishoma nezvishoma; nguva yeJurassic ndiyo yaive nguva yepamusoro-soro yenguva yemadinosaur, ine mhando dzakawanda dzakakurumbira dzichionekwa; uye nguva yeCretaceous ndiyo yaive kuguma kwenguva yemadinosaur uye zvakare nguva yakasiyana-siyana. Kuvapo nekutsakatika kwemadinosaur aya kunopa chirevo chakakosha chekudzidza kushanduka kwehupenyu nenhoroondo yePasi.
