Caqli ahaan,Pterosauriawaxay ahaayeen noocyadii ugu horreeyay taariikhda ee awood u yeeshay inay si xor ah ugu duulaan cirka. Ka dib markii shimbiruhu soo baxeen, waxay u muuqataa mid macquul ah in Pterosauria ay ahaayeen awoowayaasha shimbiraha. Si kastaba ha ahaatee, Pterosauria ma ahayn awoowayaasha shimbiraha casriga ah!
Marka hore, aan caddayno in sifada ugu aasaasiga ah ee shimbiraha ay tahay inay yeeshaan baalal baalal leh, oo aan awoodin inay duulaan! Pterosaur, oo sidoo kale loo yaqaan Pterosauria, waa xamaarato dabar go'day oo noolaa laga bilaabo Triassic-gii dambe ilaa dhammaadka Cretaceous. In kasta oo ay leedahay astaamaha duulista oo aad ugu eg shimbiraha, haddana ma haystaan baalasha. Intaa waxaa dheer, Pterosauria iyo shimbiruhu waxay ka tirsanaayeen laba nidaam oo kala duwan oo ku jira geeddi-socodka horumarka. Si kasta oo ay u kobcaan, Pterosauria ma isu beddeli karin shimbiro, iska daa awoowayaasha shimbiraha.
Haddaba halkee ayay shimbiruhu ka soo baxeen? Hadda ma jirto jawaab cad oo ka jirta bulshada sayniska. Waxaan ognahay oo keliya in Archeopteryx ay tahay shimbirtii ugu horreysay ee aan naqaanno, waxayna soo baxeen xilligii dambe ee Jurassic, iyagoo ku noolaa isla xilligii dinosaurs-ka, sidaa darteed waxaa habboon in la yiraahdo Archeopteryx waa awoowga shimbiraha casriga ah.
Way adag tahay in la sameeyo fosil shimbireed, taasoo ka dhigaysa daraasadda shimbiraha qadiimiga ah mid aad u adag. Saynisyahannadu waxay si qiyaas ah u sawiri karaan dulucda shimbirtii hore iyagoo ku saleynaya tilmaamahaas jajaban, laakiin cirka dhabta ah ee qadiimiga ah wuxuu gebi ahaanba ka duwanaan karaa male-awaalkeenna, maxaad u malaynaysaa?
