Z\u00e1hadn\u00fd Martharaptor: Nov\u00fd druh dinosaura z obdob\u00ed k\u0159\u00eddy v Utahu<\/h2>\n\n

Objev a popis<\/h2>\n\n

V drsn\u00fdch pustin\u00e1ch v\u00fdchodn\u00edho Utahu objevili paleontologov\u00e9 nov\u00fd a z\u00e1hadn\u00fd druh dinosaura, kter\u00fd dostal jm\u00e9no Martharaptor greenriverensis. Objeven byl v geologick\u00e9 formaci Cedar Mountain a jeho ostatky nazna\u010duj\u00ed, \u017ee by mohl pat\u0159it do podivn\u00e9ho a z\u00e1hadn\u00e9ho rodu terizinosauroid\u016f.<\/p>\n\n

Mezi ostatky Martharaptora pat\u0159\u00ed \u010d\u00e1sti jeho p\u0159edn\u00edch a zadn\u00edch kon\u010detin, bok\u016f, lopatky, dr\u00e1py na rukou a dal\u0161\u00ed fragmenty. A\u010dkoli je kostra ne\u00fapln\u00e1, velikost a rozm\u00edst\u011bn\u00ed kost\u00ed nazna\u010duj\u00ed, \u017ee pat\u0159\u00ed jednomu jedinci.<\/p>\n\n

Klasifikace a p\u0159\u00edbuznosti<\/h2>\n\n

Na z\u00e1klad\u011b sv\u00fdch anatomick\u00fdch znak\u016f je Martharaptor klasifikov\u00e1n jako celurosaurus, skupina teropodn\u00edch dinosaur\u016f, kter\u00e1 zahrnuje pt\u00e1ky a jejich nejbli\u017e\u0161\u00ed p\u0159\u00edbuzn\u00e9. Jeho p\u0159esn\u00e9 um\u00edst\u011bn\u00ed v rodokmenu celurosaur\u016f v\u0161ak z\u016fst\u00e1v\u00e1 nejist\u00e9.<\/p>\n\n

Auto\u0159i studie, kter\u00e1 Martharaptora popisuje, nazna\u010duj\u00ed, \u017ee by mohl b\u00fdt terizinosauridem, skupinou b\u00fdlo\u017erav\u00fdch a v\u0161e\u017erav\u00fdch dinosaur\u016f zn\u00e1m\u00fdch sv\u00fdmi dlouh\u00fdmi krky, velk\u00fdmi dr\u00e1py na rukou a t\u011b\u017ek\u00fdmi t\u011bly. Zejm\u00e9na lopatka a dr\u00e1py na rukou Martharaptora se podobaj\u00ed terizinosauridovi Falcarius, kter\u00fd byl nalezen v ni\u017e\u0161\u00edch vrstv\u00e1ch geologick\u00e9 formace Cedar Mountain.<\/p>\n\n

Evolu\u010dn\u00ed v\u00fdznam<\/h2>\n\n

Objev Martharaptora poskytuje nov\u00e9 poznatky o rozmanitosti teropodn\u00edch dinosaur\u016f v obdob\u00ed k\u0159\u00eddy. Nazna\u010duje, \u017ee rod terizinosauroid\u016f byl roz\u0161\u00ed\u0159en\u011bj\u0161\u00ed a rozmanit\u011bj\u0161\u00ed, ne\u017e se d\u0159\u00edve myslelo.<\/p>\n\n

P\u0159\u00edtomnost Martharaptora ve formaci Cedar Mountain tak\u00e9 zd\u016fraz\u0148uje bohatstv\u00ed t\u00e9to geologick\u00e9 formace jako zdroje nov\u00fdch objev\u016f dinosaur\u016f. V pr\u016fb\u011bhu let bylo mnoho nov\u00fdch druh\u016f dinosaur\u016f pojmenov\u00e1no podle nalezi\u0161\u0165 ve formaci, kter\u00e1 pokr\u00fdvaj\u00ed obdob\u00ed 30 milion\u016f let.<\/p>\n\n

Budouc\u00ed v\u00fdzkum<\/h2>\n\n

P\u0159esto\u017ee objev Martharaptora vrhl sv\u011btlo na rozmanitost dinosaur\u016f v obdob\u00ed k\u0159\u00eddy, mnoho ot\u00e1zek t\u00fdkaj\u00edc\u00edch se jeho biologie a evolu\u010dn\u00ed historie z\u016fst\u00e1v\u00e1 nezodpov\u011bzeno. Abychom pln\u011b pochopili m\u00edsto Martharaptora v rodokmenu dinosaur\u016f, mus\u00ed paleontologov\u00e9 naj\u00edt jeho kompletn\u011bj\u0161\u00ed kostru.<\/p>\n\n
