I-Pterosauria: Angilona “i-dinosaur endizayo”
Ngokubona kwethu, ama-dinosaurs ayengabaphathi bomhlaba ezikhathini zasendulo.Sikuthatha njengokujwayelekile ukuthi izilwane ezifanayo ngaleso sikhathi zonke zihlukaniswa ngokwesigaba sama-dinosaurs.Ngakho-ke, i-Pterosauria yaba "ama-dinosaurs ezindizayo".Eqinisweni, iPterosauria yayingewona ama-dinosaur!
Ama-Dinosaur abhekisela kwezinye izilwane ezihuquzelayo zasemhlabeni ezingahamba ziqonde, ngaphandle kwama-pterosaur.I-Pterosauria imane iyizilwane ezihuquzelayo ezindizayo, kanye nama-dinosaur womabili angawemifula yemvelo ye-Ornithodira.Okusho ukuthi, i-pterosauria nama-dinosaurs afana "nomzala".Bayizihlobo eziseduze, futhi bayizikhombisi-ndlela ezimbili zokuziphendukela kwemvelo ezaphila enkathini efanayo, futhi ukhokho wabo wakamuva ubizwa ngokuthi i-Ornithischiosaurus.
Ukuthuthukiswa kwamaphiko
Izwe laligcwele izibankwakazi, futhi isibhakabhaka sasigcwele ama-pterosaur.Bangumndeni, kwenzeka kanjani ukuthi omunye usesibhakabhakeni omunye uphansi?
Entshonalanga yeSifundazwe Sase-Liaoning eChina, kwatholakala iqanda le-pterosauria elacwiywa kodwa lingabonisi zimpawu zokuphuka.Kuye kwaphawulwa ukuthi ulwelwesi lwamaphiko emibungu ngaphakathi lukhule kahle, okusho ukuthi i-pterosauria ingandiza ngokushesha ngemva kokuzalwa.
Ucwaningo olwenziwa ochwepheshe abaningi lubonise ukuthi i-pterosauria yakuqala yavela kubagijimi abancane, abanezinambuzane, abanemilenze emide njengeScleromochlus, eyayinolwelwesi emilenzeni yangemuva, ifinyelela emzimbeni noma emsileni.Mhlawumbe ngenxa yesidingo sokusinda nokudlwengulwa, isikhumba sabo saba sikhulu futhi kancane kancane sakhula saba nesimo esifana namaphiko.Ngakho-ke zingaqhutshelwa phezulu futhi kancane kancane zibe izilwane ezihuquzelayo ezindizayo.
Izinsalela zibonisa ukuthi okokuqala lezi zinsizwa zazingencane nje kuphela, kodwa futhi ukuthi isakhiwo samathambo emaphikweni sasingabonakali.Kodwa kancane kancane, zaguqukela esibhakabhakeni, futhi uphiko olukhudlwana, olunemsila omfushane olundizayo lwePterosauria kancane kancane lwathatha indawo “yemincanyana”, futhi ekugcineni lwaba ukubusa emoyeni.
Ngo-2001, kwatholakala i-pterosauria fossil eJalimane.Amaphiko ale mivubukulo ayelondolozwe ngokwengxenye.Ososayensi bawukhanyisa ngokukhanya kwe-ultraviolet futhi bathola ukuthi amaphiko ayo ayewulwelwesi lwesikhumba olunemithambo yegazi, imisipha nemicu emide.Imicu ingasekela amaphiko, futhi ulwelwesi lwesikhumba lungadonswa luqine, noma lugoqwe njengefeni.Futhi ngo-2018, izinsalela ezimbili ze-pterosauria ezitholwe e-China zabonisa ukuthi nazo zinezimpaphe zakudala, kodwa ngokungafani nezimpaphe zezinyoni, izimpaphe zazo zazizincane futhi zine-fluffy ezingase zisetshenziswe ukugcina izinga lokushisa lomzimba.
Kunzima ukundiza
Ingabe uyazi?Phakathi kwezinsalela ezitholakele, amaphiko e-pterosauria amakhulu angakhula ngamamitha ayi-10.Ngakho-ke, abanye ochwepheshe bakholelwa ukuthi ngisho noma inamaphiko amabili, enye i-pterosauria enkulu ayikwazi ukundiza isikhathi eside nebanga elide njengezinyoni, futhi abanye abantu baze bacabange ukuthi ingase ingandizi nhlobo!Ngoba zisindwa kakhulu!
Nokho, indlela i-pterosauria eyandiza ngayo ayikacaci.Abanye ososayensi baphinde bacabange ukuthi mhlawumbe i-pterosauria ayizange isebenzise ukuntweza njengezinyoni, kodwa amaphiko azo azishintshashintshayo, akha isakhiwo esiyingqayizivele sokuzungeza umoya.Nakuba i-pterosauria enkulu yayidinga izitho eziqinile ukuze isuke phansi, kodwa amathambo awugqinsi ayewenza abe nzima kakhulu.Ngokushesha, bathola indlela!Amathambo ephiko le-pterosauria aguquke abe amashubhu angenalutho anezindonga ezincane, ezawavumela ukuba "alahlekelwe isisindo" ngempumelelo, abe nezimo eziguquguqukayo futhi angasindi, futhi angandiza kalula.
Abanye bathi i-pterosauria yayingakwazi ukundiza nje kuphela, kodwa yehla njengezinkozi ukuze idle izinhlanzi ebusweni bolwandle, amachibi, nemifula.Indiza yayivumela i-pterosauria ukuthi ihambe amabanga amade, ibaleke izilwane ezidla ezinye futhi ithuthukise izindawo zokuhlala ezintsha.
