Pterosauria: Ini handisi "inobhururuka dinosaur"
Mukuziva kwedu, madhinosaurs aive madzishe enyika munguva dzekare.Isu tinozvitora sezvinei kuti mhuka dzakafanana panguva iyoyo dzakaiswa muchikamu chemadinosaur.Saka, Pterosauria yakava "inobhururuka dinosaurs".Kutaura idi, Pterosauria akanga asiri madinosaur!
Madhinairosi anoreva zvimwe zvinokambaira zvepanyika zvinokwanisa kufamba zvakati twasu, kusasanganisa mapterosaur.Pterosauria zvingori zvinokambaira zvinobhururuka, pamwe chete nemadinosaur ese ndeezve evolutionary tributaries yeOrnithodira.Kureva kuti, pterosauria uye dinosaurs akafanana "cousin".Ivo ihama dzepedyo, uye inzira mbiri dzekushanduka-shanduka dzakararama panguva imwe chete, uye tateguru wavo achangoburwa anonzi Ornithischiosaurus.
Bapiro kukura
Nyika yacho yaitongwa nemadinosaur, uye denga rakanga rakazara nemapterosaur.Ivo imhuri, sei mumwe ari mudenga mumwe ari pasi?
Kumadokero kwePurovhinzi yeLiaoning kuChina, zai repterosauria rakawanwa iro rakapwanywa asi risina kuratidza zviratidzo zvokutyoka.Zvakanga zvaonekwa kuti mapapiro emaembryos ari mukati akakura zvakanaka, zvinoreva kuti pterosauria inogona kubhururuka mushure mekuzvarwa.
Tsvagiridzo yakaitwa nenyanzvi dzakawanda yakaratidza kuti yekutanga pterosauria yakabva kune diki, zvipembenene, zvipembenene zvine makumbo marefu ekumhanya seScleromochlus, iyo yaive nema membrane pamakumbo avo eshure, ichienda kumuviri kana muswe.Zvichida nekuda kwekudiwa kwekupona uye kudzvinyirirwa, ganda ravo rakava rakakura uye zvishoma nezvishoma rakava chimiro chakafanana nemapapiro.Saka dzaigonawo kukwidzwa mudenga uye zvishoma nezvishoma kukudziridzwa kuita zvinokambaira zvinobhururuka.
Zvisaririra zvinoratidza kuti kutanga majaya aya akange asiri madiki chete, asiwo kuti chimiro chepfupa mumapapiro chaive chisiri pachena.Asi zvishoma nezvishoma, dzakashanduka dzakananga kudenga, uye bapiro guru, rine muswe mupfupi Pterosauria zvishoma nezvishoma rakatsiva “maduku”, uye rakazopedzisira rava kutonga kwemhepo.
Muna 2001, pterosauria fossil yakawanikwa muGermany.Mapapiro ezvisaririra zvacho akanga akachengetedzwa zvishoma.Masayendisiti akaivhenekera nechiedza che ultraviolet uye akaona kuti mapapiro ayo aive membrane yeganda ine tsinga dzeropa, tsandanyama uye refu fiber.Fibers dzinogona kutsigira mapapiro, uye membrane yeganda inogona kudhonzwa yakasimba, kana kupetwa senge fan.Uye muna 2018, maviri pterosauria fossils akawanikwa kuChina airatidza kuti aivewo neminhenga yechinyakare, asi kusiyana neminhenga yeshiri, minhenga yadzo yaive midiki uye yakawanda fluffy inogona kushandiswa kuchengetedza tembiricha yemuviri.
Kubhururuka kwakaoma
Unoziva here?Pakati pezvinyorwa zvakawanikwa, mapapiro emapapiro makuru epterosauria anogona kuwedzera mamita gumi.Naizvozvo, dzimwe nyanzvi dzinodavira kuti kunyange dziine mapapiro maviri, dzimwe pterosauria huru haigoni kubhururuka kwenguva refu uye kureba seshiri, uye vamwe vanhu vanotofunga kuti dzingasatongobhururuka!Nokuti dzakanyanya kurema!
Zvisinei, nzira iyo pterosauria yakabhururuka nayo haisati yanyatsojeka.Mamwe masayendisiti anofungidzirawo kuti zvichida pterosauria haina kushandisa kubhururuka seshiri, asi mapapiro adzo akashanduka ari oga, achigadzira chimiro chakasiyana chemhepo.Kunyange zvazvo pterosauria yakakura yaida makumbo akasimba kuti ibve pasi, asi mapfupa akakora aiita kuti awedzere kurema.Nenguva isipi, vakafunga nzira!Mapfupa emapapiro epterosauria akashanduka kuita machubhu asina mhango ane madziro matete, izvo zvakavabvumira "kurasikirwa nehuremu" zvinobudirira, vachiwedzera kuchinjika uye kureruka, uye vanogona kubhururuka zvakanyanya nyore.
Vamwewo vanoti pterosauria yaisagona kubhururuka chete, asi yaibhururuka semakondo kuti ibate hove kubva pamusoro pemakungwa, nyanza, nenzizi.Kubhururuka kwakabvumira pterosauria kufamba nzendo refu, kutiza zvikara uye kugadzira nzvimbo itsva dzekugara.
