Zvinonzwisisika,Pterosauriandiwo akanga ari marudzi ekutanga munhoroondo kukwanisa kubhururuka zvakasununguka mudenga. Uye pashure pokunge shiri dzaoneka, kunoratidzika kuva kune mufungo kuti Pterosauria akanga ari madzitateguru eshiri. Zvisinei, Pterosauria yakanga isiri madzitateguru eshiri dzemazuva ano!
Chokutanga, ngatijekesei kuti chinhu chinonyanya kukosha cheshiri kuva nemapapiro ane minhenga, kwete kukwanisa kubhururuka! Pterosaur, inozivikanwawo sePterosauria, chikara chakatsakatika chaigara kubva kuLate Triassic kusvika kumagumo eCretaceous. Kunyange zvazvo iine hunhu hwekubhururuka hwakafanana neshiri, hadzina minhenga yacho. Pamusoro pezvo, Pterosauria neshiri dzaive dzehurongwa huviri hwakasiyana mukushanduka-shanduka. Hazvinei hazvo nokuti dzakakura sei, Pterosauria yaisagona kushanduka kuva shiri, ndoda madziteteguru eshiri.
Saka shiri dzakabva kupi? Parizvino hapana mhinduro chaiyo munharaunda yesainzi. Isu tinongoziva kuti Archeopteryx ndiyo shiri yekutanga yatinoziva, uye yakaonekwa munguva yekupedzisira yeJurassic, ichirarama panguva imwechete semadinosaurs, saka zvakakodzera kutaura kuti Archeopteryx ndiye tateguru weshiri dzemazuva ano.
Zvakaoma kugadzira zvisaririra zveshiri, izvo zvinoita kuti kudzidza kweshiri dzekare kunyanye kuoma. Masayendisiti anongokwanisa kudhirowa ratidziro yeshiri yekare zvichibva pane izvo zvakakamurwa zviratidzo, asi denga chairo rekare rinogona kunge rakasiyana zvachose nemafungiro edu, unofungei?
