tethydraco, lagbhag 66 million varsh pahale vartamaan morakko key kshetra key cretaceous avadhi (mastrictian charan) key anta mein rahane vaale terrodectyloid terrosor kaa ack vansh haye. "tethydraco" mool roop seey pateranodontidae parivaar koo saunpa gayaa thaa. kuchh shodhkartaon ney tark diyaa kii baad mein varnit samagri seey pataa chalata haye kii yeh ack azdarkid hoe sakata haye, aur sambhavatah "phosphatodra" kaa paryaay hoe sakata haye, halanki yeh vivaadit rhaa haye. prakaar aur ekmatra prajaati tii haye. rajo.
khoj aur namkaran.
2015 seey, jeevashmavidon kaa ack samooh vaanijyik morocan jeevaashm vyapariyon seey paterosaur jeevaashm praapt curr rhaa haye, joe inhen khauriba pathaar parr phosphat khadanon mein shramikon seey praapt karate hain, joe kii abdaun besin key bheetar sthit haye. iss pariyojana kaa uddeshya navintam cretaceous mein terosaur vividhata kaa nirdhaaran karna haye. iss charan seey, koee bhee konsarvat-laserstaton gyaat naheen haye, joe asadharan sanrakshan key saath prajaatiyon kii ack badee vividhata koo jodata haye. aise sthalon mein hii adhikansh paterosaur jeevaashm aur vargeekaran kii khoj kii gaee haye. navintam cretaceous ney kewal azdarchidae key kuchh aanshik kankalon kaa utpaadan kiya thaa. shodhkartaon ney aamtaur parr iss tathya seey nishkarsh nikala haye kii anya terosaur samooh pahale hii vilupt hoe chuke they. haalaanki, ack vaikalpik vyakhya yeh hoe sakati haye kii kharaab jeevaashm record ney undersampling key madhyam seey vaastavik sthiti kii vikrit chhavi paida kii. iss parikalpana kaa pareekshan karane key liye, key-haurigba phosphat paraton key badey paimaane parr aur vyavasthit vaanijyik dohan dwara prakaash mein laae gaye sabhi terosaur haddiyon koo ikattha karane kaa prayaas kiya gayaa thaa. yeh pataa chalaa kii vaastav mein kuchh khojon koo ezdarkids key roop mein nirdhaarit naheen kiya jaa sakata thaa aur sambhavatah anya samoohon kaa pratinidhitva kartaa thaa. 2018 mein chaar nishkarshon koo naee prajaatiyon key roop mein varnit kiya gayaa thaa, jisamen tethydraco bhee shamil thaa.
2018 mein, nicolaus aar. longrich, david aim. martle aur bryan andress ney iss prakaar kii prajaati kaa varnan kiya aur iska naam "tethydraco reglis" rakhaa. samanya naam tethys key sandarbh koo jodata haye, joe europe aur asia seey africa koo alag karane vaale cretaceous key anta mein mahasagar haye, jisamen ack lattin "draco", "dragon" haye. lattin mein vishisht naam kaa arth haye "shaahi".
holotype, fsac-obi 1, beach key "kauche III" mein paaya gayaa thaa, joe khud sidi daui mein sabse cumm phosphat parat parisar haye, joe dair seey mastrictian seey detting kartaa haye. isamen ack baaen humourous hotaa haye. huddy apekshaakrit kuchal dee jaati haye. anya namoonon koo prajaatiyon key liye sandarbhit kiya gayaa haye. fsac-obi 199 ack alna haye. fsac-obi 200 ack aur alna haye. fsac-obi 201 ack thibon haye. fsac-obi 202 mein shinbone key saath ack thibon hotaa haye. varnan karane vaale lekhakon ney sweekaar kiya kii ativyaapi samagri kii kamee koo dekhate hue, holotype aur sandarbhit namoonon key beach sambandh koo saabit karna mushkil haye. haalaanki, chaude alna humourous kii asadharan doorasth chaudaai key anuroop hotey hain. janghon koo adhik asthaayi roop seey sandarbhit kiya gayaa thaa kyonki way terranodonted prateet hotey they.
varnan.
"tethydraco" key pankhon aur shareer kaa dravyamaan thaa.
varnan karane vaale lekhakon ney kuchh lakshnon kaa sanket diyaa jisamen "tethydraco" koo gyaat pateranodonted seey alag kiya jaa sakata haye. humourous mein, deltopectoral crest koo janwar key dhad key karib, balki nikatvarti roop seey rakhaa jaataa haye, isaki nikatatam seema vipareet crest, "christa ulnaris" kii shuruat key nikat sthit hoti haye. door, dhad seey door, humourous kaa ack vyaapak trikoniya vistaar hotaa haye. baahari jodd condyle kii or chalane vaali huddy kii katak kii ack alag prakriya hoti haye joe oopar kii or ishara karati haye, jaba pankh ack vistaarit sthiti mein hotaa haye. bheetari condyle kii or jaane vaali katak badee hoe jaati haye aur lambi doori taka dhad kii or faili hoti haye. alna apekshaakrit chhota aur chauda hotaa haye jabaki iska sameepavarti chhor, humourous kii or, badey paimaane parr vistaarit hotaa haye.
phylogeny.
"tethydraco" koo pateranodontidae parivaar mein rakhaa gayaa thaa; yeh usa parivaar kaa sabse cumm umr kaa gyaat sadasya hoga, kyonki isake jeevaashm 66 million saal pahale key hain. isake astitva koo iss baat key pramaan key roop mein dekhaa gayaa kii mastrictian mein pectorosaur kii vividhata pahale kii tulanaa mein adhik thee. spasht roop seey terosaur kaa patan sanket-lip prabhaav key kaaran ack bhram rhaa hoga, samooh badey paimaane parr vilupt honey seey pahale gayab hoe jaate hain kyonki sanyog seey unake sabse chhote jeevaashm vilupt honey kii ghatana kii tulanaa mein kuchh purani paraton parr paae gaye hain.
neeche ack cladogram haye joe pahali baar 2014 mein andress aur sahyogiyon dwara prastut ack phylogenetic vishleshan key parinamon koo darshaata haye, aur 2018 mein longrich aur sahyogiyon dwara atirikt detta key saath adyatan kiya gayaa haye. iss vishleshan mein, unhone paaya kii "tethydraco" "peteranodon" ("pee. longiseps "aur" pee. sternbergy); way teenon parivaar pateranodontidae banaate hain, joe nictosauridae parivaar key bahan vargeekaran key roop mein paaya jaataa haye.
2020 mein, usee jamaa seey ack pankh koo genus koo saunpa gayaa thaa; haalaanki, roopvigyaan ney sujhaav diyaa kii "tethydraco" ack azdarkid thaa, bajaay ack pateranodonted key jaisa kii mool roop seey prastaavit thaa, aur sambhavatah "phosphatoderoco" key pankh-tatvon kaa pratinidhitva kartaa thaa. 2022 mein, "apapetello" kaa varnan karane vaale shodhkartaon ney nott kiya kii "apapetello" kaa humourous "tethydraco" aur anya gair-"nictosaurus" pateranodontoids key saath samaantaa saajha kartaa haye, aur "peteranodon" seey nikatata seey sambandhit ack peteranodon key roop mein "tethydraco" koo baramad kiya.
jeevaashm vigyaan.
"tethydraco" kii khoj morakko mein abdaun besin mein kii gaee thee. iss besin koo "sophe" naamak paraton mein vibhajit kiya gayaa haye, aur "tethydraco" koo sophe mein khoja gayaa thaa. yeh pectorosaur "alcione", "berberidectillus", "simurghiya" aur "phosphatodra" aur abelisorid dynasore "chenenisorus" key saath saha-astitva mein thaa.
