Ngengqiqo,Pterosauriayayizintlobo zokuqala embalini ukukwazi ukubhabha ngokukhululekileyo esibhakabhakeni. Yaye emva kokuvela kweentaka, kubonakala kusengqiqweni ukuba iPterosauria yayizizinyanya zeentaka. Noko ke, iPterosauria yayingengookhokho beentaka zanamhlanje!
Okokuqala, makhe sicace ukuba eyona nto isisiseko kwiintaka kukuba namaphiko aneentsiba, akukwazi ukubhabha! I-Pterosaur, ekwabizwa ngokuba yiPterosauria, sisirhubuluzi esingasekhoyo esasihlala ukusuka kwiLate Triassic ukuya ekupheleni kweCretaceous. Nangona ineempawu zokubhabha ezifana kakhulu neentaka, azinazo iintsiba. Ukongeza, iPterosauria kunye neentaka bezikwinkqubo ezimbini ezahlukeneyo kwinkqubo yendaleko. Kungakhathaliseki ukuba zakhula njani, iPterosauria yayingenakuguquka ibe ziintaka, kungasathethwa ke ngookhokho beentaka.
Ngoko iintaka zavela phi? Okwangoku akukho mpendulo iqinisekileyo kuluntu lwezenzululwazi. Siyazi kuphela ukuba i-Archeopteryx yintaka yokuqala esiyaziyo, kwaye yavela ekupheleni kwexesha le-Jurassic, ehlala ngexesha elifanayo leedinosaurs, ngoko kufaneleka ngakumbi ukuthetha ukuba i-Archeopteryx yikhokho yeentaka zanamhlanje.
Kunzima ukwenza iifosili zeentaka, nto leyo eyenza kube nzima ngakumbi ukufunda ngeentaka zamandulo. Iingcali zenzululwazi ziyakwazi ukuzoba inkcazo yentaka yakudala ngokusekwe kwezo zikhokelo ziqhekezayo, kodwa isibhakabhaka samandulo sinokwahluka ngokupheleleyo kwingcinga yethu, ucinga ntoni?
