Tyrannosaurus Rex (T. rex) byl obrovsk\u00fd pred\u00e1tor, kter\u00fd dominoval Zemi p\u0159ed miliony let. Byl p\u0159ibli\u017en\u011b 13 metr\u016f dlouh\u00fd a v\u00e1\u017eil kolem 7 tun. T. rex m\u011bl d\u011bsiv\u00fd vzhled s mohutn\u00fdmi \u010delistmi osazen\u00fdmi 15centimetrov\u00fdmi zuby. Jedn\u00edm z jeho nejpodivn\u011bj\u0161\u00edch rys\u016f v\u0161ak byla kr\u00e1tk\u00e1, zakrn\u011bl\u00e1 p\u0159edlokt\u00ed, kter\u00e1 byla dlouh\u00e1 jen asi metr.<\/p>\n\n
Mal\u00e1 velikost p\u0159edlokt\u00ed T. rexe v\u011bdce po desetilet\u00ed m\u00e1tla. N\u011bkte\u0159\u00ed ran\u00ed paleontologov\u00e9, jako nap\u0159\u00edklad Henry F. Osborn, zpochyb\u0148ovali, zda p\u0159edlokt\u00ed v\u016fbec pat\u0159\u00ed k T. rexovi. Byla p\u0159\u00edli\u0161 kr\u00e1tk\u00e1 na to, aby dos\u00e1hla k \u00fast\u016fm nebo si po\u0161kr\u00e1bala nos, co\u017e vedlo ke spekulac\u00edm o jejich funkci.<\/p>\n\n
V pr\u016fb\u011bhu let navrhli paleontologov\u00e9 r\u016fzn\u00e9 teorie, aby vysv\u011btlili \u00fa\u010del zakrn\u011bl\u00fdch p\u0159edlokt\u00ed T. rexe. N\u011bkte\u0159\u00ed v\u011b\u0159ili, \u017ee byly pou\u017eity jako \u201euchopuj\u00edc\u00ed org\u00e1n\u201c p\u0159i p\u00e1\u0159en\u00ed. Jin\u00ed nazna\u010dovali, \u017ee pomohly T. rexovi postavit se zp\u0159\u00edma po p\u00e1du. Dal\u0161\u00ed tvrdili, \u017ee \u0161lo o zakrn\u011bl\u00e9 org\u00e1ny, poz\u016fstatky evolu\u010dn\u00ed minulosti.<\/p>\n\n
Jedna teorie, kter\u00e1 z\u00edskala na popularit\u011b, byla my\u0161lenka, \u017ee T. rex byl sp\u00ed\u0161e mrcho\u017erout ne\u017e lovec. Jeho slab\u00e9 p\u0159edlokt\u00ed by mu zt\u011b\u017eovalo chyt\u00e1n\u00ed a zdol\u00e1v\u00e1n\u00ed ko\u0159isti. M\u00edsto toho mohl T. rex \u017er\u00e1t mr\u0161iny zanechan\u00e9 jin\u00fdmi pred\u00e1tory.<\/p>\n\n
Ned\u00e1vn\u00fd v\u00fdzkum v\u0161ak zpochybnil hypot\u00e9zu o mrcho\u017eroutstv\u00ed. Paleontologov\u00e9 Kenneth Carpenter a Matt Smith provedli studie, kter\u00e9 odhalily, \u017ee p\u0159edlokt\u00ed T. rexe, a\u010dkoli byla kr\u00e1tk\u00e1, byla neuv\u011b\u0159iteln\u011b siln\u00e1. Svaly v horn\u00edch p\u0159edlokt\u00edch byly v\u00edce ne\u017e t\u0159ikr\u00e1t siln\u011bj\u0161\u00ed ne\u017e u lid\u00ed.<\/p>\n\n
Carpenter a Smith navrhli, \u017ee T. rex pou\u017e\u00edval sv\u00e9 siln\u00e9 \u010delisti k uchopen\u00ed ko\u0159isti a pot\u00e9 p\u0159edlokt\u00edmi p\u0159itiskl se zm\u00edtaj\u00edc\u00ed zv\u00ed\u0159e k t\u011blu, aby mu zabr\u00e1nil v \u00fat\u011bku. Tato teorie nazna\u010duje, \u017ee T. rex byl skute\u010dn\u011b zdatn\u00fd pred\u00e1tor, schopn\u00fd p\u0159epadnout a p\u0159emoci velkou ko\u0159ist.<\/p>\n\n
A\u010dkoli byl T. rex prim\u00e1rn\u011b pred\u00e1torem, pravd\u011bpodobn\u011b se p\u0159\u00edle\u017eitostn\u011b \u017eivil mr\u0161inami, kdy\u017e se naskytla p\u0159\u00edle\u017eitost. Jeho j\u00eddeln\u00ed\u010dek se skl\u00e1dal z r\u016fzn\u00fdch zv\u00ed\u0159at, v\u010detn\u011b b\u00fdlo\u017eravc\u016f, jako jsou triceratops a hadrosau\u0159i. T. rex m\u011bl jedine\u010dnou metodu lovu. St\u00edhal svou ko\u0159ist a pak na ni za\u00fato\u010dil siln\u00fdm kousnut\u00edm do krku nebo hlavy. Jeho ostr\u00e9 zuby mohly rozdrtit kosti a roztrhat maso, co\u017e mu umo\u017enilo rychle p\u0159emoci sv\u00e9 ob\u011bti.<\/p>\n\n
Navzdory sv\u00fdm kr\u00e1tk\u00fdm p\u0159edlokt\u00edm byl Tyrannosaurus Rex impozantn\u00edm pred\u00e1torem, kter\u00fd dominoval sv\u00e9mu prost\u0159ed\u00ed. Jeho siln\u00e9 \u010delisti, mohutn\u00e1 p\u0159edlokt\u00ed a agresivn\u00ed loveck\u00e9 taktiky z n\u011bj u\u010dinily jedno z nejikoni\u010dt\u011bj\u0161\u00edch a nejob\u00e1van\u011bj\u0161\u00edch tvor\u016f v historii Zem\u011b.<\/p>","protected":false},"excerpt":{"rendered":"
