Zvinonzwisisika,PterosauriaNdiwo marudzi ekutanga munhoroondo kukwanisa kubhururuka mudenga zvakasununguka. Uye mushure mekunge shiri dzaonekwa, zvinoita sezvine musoro kuti Pterosauria ndiyo yaive madzitateguru eshiri. Zvisinei, Pterosauria yakanga isiri madzitateguru eshiri dzemazuva ano!
Kutanga, ngative pachena kuti chinhu chikuru cheshiri ndechekuva nemapapiro ane minhenga, kwete kukwanisa kubhururuka! Pterosaur, inozivikanwawo sePterosauria, imhuka inokambaira yakatsakatika yakagara kubva kuLate Triassic kusvika kumagumo eCretaceous. Kunyangwe iine hunhu hwekubhururuka hwakafanana zvikuru neshiri, hadzina minhenga. Pamusoro pezvo, Pterosauria neshiri zvaive zvemasystem maviri akasiyana mukushanduka-shanduka. Pasinei nekuti dzakakura sei, Pterosauria yaisagona kushanduka kuita shiri, tisingatauri nezvemadzitateguru eshiri.
Saka shiri dzakabva kupi? Parizvino hapana mhinduro chaiyo munharaunda yesainzi. Tinongoziva chete kuti Archaeopteryx ndiyo shiri yekutanga yatinoziva, uye dzakaonekwa munguva yekupedzisira yeJurassic, dzichirarama munguva imwecheteyo nemadinosaur, saka zvakakodzera kutaura kuti Archaeopteryx ndiye tateguru weshiri dzemazuva ano.
Zvakaoma kugadzira zvisaririra zveshiri, izvo zvinoita kuti kudzidza nezveshiri dzekare kuome zvakanyanya. Masayendisiti anogona kungonyora mufananidzo weshiri yekare zvichibva pane zviratidzo izvozvo zvakapwanyika, asi denga rekare chairo rinogona kunge rakasiyana zvachose nepfungwa dzedu, munofungei?
