Paleontologov\u00e9 objevili nov\u00fd druh pt\u00e1kovit\u00e9ho dinosaura v jihov\u00fdchodn\u00ed \u010c\u00edn\u011b. 150 milion\u016f let star\u00fd tvor, pojmenovan\u00fd Fujianvenator prodigiosus, byl nalezen v provincii Fujian pobl\u00ed\u017e m\u011bsta Nan-pching.<\/p>\n\n
Fujianvenator prodigiosus m\u011bl podivuhodnou kombinaci fyziologick\u00fdch rys\u016f. Jeho nejn\u00e1padn\u011bj\u0161\u00ed charakteristikou byly prodlou\u017een\u00e9 nohy, kter\u00e9 byly dvakr\u00e1t del\u0161\u00ed ne\u017e jeho stehna. M\u011bl tak\u00e9 p\u0159edn\u00ed kon\u010detiny podobn\u00e9 pta\u010d\u00edm k\u0159\u00eddl\u016fm, ale s p\u0159id\u00e1n\u00edm t\u0159\u00ed dr\u00e1pat\u00fdch prst\u016f a dr\u00e1p\u016f.<\/p>\n\n
V\u011bdci si st\u00e1le nejsou jisti p\u0159esn\u00fdm chov\u00e1n\u00edm Fujianvenator prodigiosus. Na z\u00e1klad\u011b jeho dlouh\u00fdch nohou se domn\u00edvaj\u00ed, \u017ee byl bu\u010f zdatn\u00fd b\u011b\u017eec, jako je pt\u00e1k emu nebo p\u0161tros, nebo brodiv\u00fd pt\u00e1k, jako je volavka nebo je\u0159\u00e1b.<\/p>\n\n
Objev Fujianvenator prodigiosus v ba\u017einat\u00e9 oblasti nazna\u010duje, \u017ee mohl b\u00fdt brodiv\u00fdm pt\u00e1kem. To je podpo\u0159eno skute\u010dnost\u00ed, \u017ee dal\u0161\u00ed fosilie nalezen\u00e9 v okol\u00ed zahrnuj\u00ed vodn\u00ed plazy, ryby a \u017eelvy.<\/p>\n\n
Bahno, sediment a voda v ba\u017einat\u00e9 oblasti mohly zabr\u00e1nit kysl\u00edku, aby se dostal ke kostem Fujianvenator prodigiosus, co\u017e by zabr\u00e1nilo rozkladu a p\u0159isp\u011blo k jeho v\u00fdborn\u00e9mu zachov\u00e1n\u00ed.<\/p>\n\n
Fujianvenator prodigiosus pat\u0159\u00ed mezi nejran\u011bj\u0161\u00ed zn\u00e1m\u00e9 pt\u00e1kovit\u00e9 dinosaury. M\u00e1 mnoho podobnost\u00ed s archeopterygem, nejstar\u0161\u00edm zn\u00e1m\u00fdm pt\u00e1kem, ale jeho prodlou\u017een\u00e9 nohy ho odli\u0161uj\u00ed. Oba dinosau\u0159i jsou pova\u017eov\u00e1ni za pt\u00e1ky, skupinu, kter\u00e1 se odd\u011blila od teropodn\u00edch dinosaur\u016f, jako je Velociraptor a Tyrannosaurus rex, a za\u010dala proces v\u00fdvoje v modern\u00ed pt\u00e1ky.<\/p>\n\n
Objev Fujianvenator prodigiosus pom\u00e1h\u00e1 vyplnit n\u011bkter\u00e9 mezery v z\u00e1znamu fosili\u00ed o v\u00fdvoji pt\u00e1k\u016f. St\u00e1le je v\u0161ak mnoho nezn\u00e1m\u00e9ho o p\u0159echodu od teropodn\u00edch dinosaur\u016f k pt\u00e1k\u016fm.<\/p>\n\n
Objev Fujianvenator prodigiosus poskytuje nov\u00e9 poznatky o ran\u00e9m v\u00fdvoji pt\u00e1k\u016f. Nazna\u010duje, \u017ee p\u0159echod od teropodn\u00edch dinosaur\u016f k pt\u00e1k\u016fm byl postupn\u00fd proces, kter\u00fd zahrnoval \u0159adu adaptac\u00ed, v\u010detn\u011b v\u00fdvoje prodlou\u017een\u00fdch nohou a p\u0159edn\u00edch kon\u010detin vhodn\u00fdch pro let.<\/p>\n\n
V\u011bdci doufaj\u00ed, \u017ee budou pokra\u010dovat ve studiu Fujianvenator prodigiosus a dal\u0161\u00edch pt\u00e1kovit\u00fdch dinosaur\u016f, aby se dozv\u011bd\u011bli v\u00edce o v\u00fdvoji pt\u00e1k\u016f. Zejm\u00e9na je zaj\u00edmaj\u00ed pochopen\u00ed faktor\u016f, kter\u00e9 vedly k v\u00fdvoji letu a diverzifikaci pt\u00e1k\u016f do \u0161irok\u00e9 \u0161k\u00e1ly druh\u016f, kter\u00e9 vid\u00edme dnes.<\/p>","protected":false},"excerpt":{"rendered":"
