Ngo-1801, izinsalela zesidalwa esingaziwa zawa ngephutha ezandleni zikasosayensi waseFrance, kanye nesibabule setshe lapho kubonakala khona ngokucacile.

Ngemuva kokutadisha ngokucophelela lokho okutholakele, uGeorges Cuvier wenza isiphetho sokuthi kungenzeka ukuthi lolu hlobo lwedayinaso lwalunamandla ukundiza.

KwakunguGeorges Cuvier owanikeza igama leli lizard elindizayo - i- "pterodactyl".

I-Pterodactyl isilwane sokuqala ukundiza

I-Pterodactyl yayinamathambo akhanyayo futhi angenalutho, okwamvumela ukuba andize. Amasayizi ale dinosaur aqala ngosayizi omncane kakhulu ukusuka kundlunkulu kuya kumakhulu ikakhulukazi ngamaphiko angamamitha ayi-12.

Izimpiko zaziwuhlobo lwesibaya sesikhumba. Elinye umkhawulo lalinamathiselwe emzimbeni, futhi umphetho wesibili wawubekiwe kwiminwe yangaphambili.

I-vertebrae yomlomo wesibeletho ingene engxenyeni ende yomgogodla. Amapayi ayeneminwe, okwenza ukuthi i-pterodactyl ibambe izinhlanzi lapho zibhabha khona kanye emanzini.

I-Pterodactyl

Izidumbu zePterodactyl zatholakala yonke indawo zisuka eNyakatho Melika zaya kwiVolga yaseRussia. Ukuhlelwa kwekhanda kanye namazinyo kufakazela lokho akuthandayo okwenziwa ngama-herbivorous, ngokukhetha inhlanzi okubandakanya. Futhi, ngokusobala, wayedla zonke izinhlobo zezinambuzane. Kunombono wokuthi abengabaze ukuphanga izidleke futhi badle ngamaqanda abantu bezinye izizwe.

Amazinyo wePterodactyl mancane futhi angavamile ukusethwa, futhi ikhanda likhulu ngoqhwaku olude. Kepha kamuva ama-pterodactyls awasenamazinyo, uqhwaku lwawo lwalufana nezinyoni zesimanje. Izimpiko zePterodactyl azilutho ngaphandle kolwelwesi phakathi kweminwe. Okufana kakhulu namalulwane.

Amathambo we-pterodactyl - idayinaso ezindizayo.

Bebheka izinsalela, ososayensi bathi ama-pterodactyls awazange andize ngokuzethemba okukhulu, kodwa angakwazi ukubambelela emoyeni isikhathi eside futhi andize.

I-pterodactyl yayinomsila, hhayi isikhathi eside kakhulu, kodwa ibaluleke kakhulu kuye ekubalekeni, kwaba ngosizo lomsila ukuthi aqondise indiza yakhe njengomhlanga. Ngenxa yomsila, i-pterodactyl yayikwazi ukuqondisa kahle, ngokushesha yehle futhi isheshise phezulu phezulu. Kungaphikiswa ukuthi kwakungu-pterodactyl owaba ngumsunguli wezinyoni zesimanje.

Ama-Pterodactyls eholidini

Inhlangano yezitho zomzimba we-pterodactyl ikhombisa ukuthi emhlabeni bebengasizakali nhlobo, futhi babekwazi ukunyakaza nje ngokukhamba. Lapho befika emhlabeni, kwakuqabukela baphume, ngenxa yokungakwazi ukusiza, baba izisulu ezilula zezinyamazane. Kepha emoyeni ngesikhathi sezindiza, abasongelanga nakancane. Ngakho-ke, balala, baqonda phansi, banamathela emgodini noma egatsheni elinamadwala.

Ngenqubo yokuguqulwa kwe-pterodactyl, umsila wehle waze wanyamalala ngokuphelele, lokhu kuhlotshaniswa nokusungulwa kanye nokukhula kwengqondo, okuqondise futhi kuqondise ukunyakaza kwe-pterodactyl.

Izinsalela ezisindile ze-pterodactyl.

I-pterodactyl yafa eminyakeni eyizigidi ezingama-145 eyedlule, futhi isikhathi sokusa kwayo sehla kwiCretaceous. Ama-Pterodactyls kwakuyizilwane zomhlambi ezazincamela ukuhlangana ngamaqembu amaningi. Bakhulisa inzalo yabo ezidlekeni, futhi bahlala edwaleni ezindaweni ezisondele kakhulu olwandle nasolwandle. Ama-Pterodactyl abheka ngokucophelela ukuthuthuka nokukhula kwezingane zawo, izinhlanzi ezondliwe ngokucophelela, zafundiswa ukundiza, futhi zihlala ephaketheni.
