Ngokwengqiqo,I-Pterosauriayayiziindidi zokuqala kwimbali ukukwazi ukubhabha ngokukhululekileyo esibhakabhakeni. Kwaye emva kokuba iintaka zivele, kubonakala kunengqondo ukuba iiPterosauria zaziziinkulu zeentaka. Nangona kunjalo, iiPterosauria zazingezizo iinkulu zeentaka zanamhlanje!
Okokuqala, masicace ukuba uphawu oluphambili lweentaka kukuba namaphiko aneentsiba, kungekhona ukukwazi ukubhabha! I-Pterosaur, eyaziwa ngokuba yi-Pterosauria, sisirhubuluzi esiphelileyo esaphila ukususela kwi-Late Triassic ukuya ekupheleni kweCretaceous. Nangona ineempawu zokubhabha ezifana kakhulu neentaka, azinazo iintsiba. Ukongeza, i-Pterosauria kunye neentaka zazikwiinkqubo ezimbini ezahlukeneyo kwinkqubo yokuzivelela. Nokuba zaphuhliswa njani, i-Pterosauria yayingenakuvela ibe ziintaka, ingasathethwa ke ngookhokho beentaka.
Ngoko ke iintaka zavela phi? Okwangoku akukho mpendulo icacileyo kuluntu lwezenzululwazi. Sazi kuphela ukuba iArcheopteryx yeyona ntaka yokuqala esiyaziyo, kwaye yavela kwixesha lokugqibela leJurassic, iphila kwixesha elifanayo needinosaur, ngoko ke kufanelekile ngakumbi ukuthi iArcheopteryx ngukhokho weentaka zanamhlanje.
Kunzima ukwenza iifosili zeentaka, nto leyo eyenza ukufunda ngeentaka zakudala kube nzima nangakumbi. Izazinzulu zinokuzoba nje umphandle wentaka yamandulo ngokusekelwe kwezo mpawu ziqhekekileyo, kodwa isibhakabhaka sokwenyani samandulo sinokwahluka ngokupheleleyo kwingcinga yethu, ucinga ntoni?
