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

Utahraptor, kolos\u00e1ln\u00ed raptor, kter\u00fd \u017eil v obdob\u00ed k\u0159\u00eddy, byl poprv\u00e9 objeven v roce 1991 paleontologem Jimem Kirklandem a jeho t\u00fdmem. P\u016fvodn\u00ed n\u00e1lez sest\u00e1val z \u00falomku \u010delisti a velk\u00e9ho srpkovit\u00e9ho dr\u00e1pu, kter\u00fd se podobal charakteristick\u00e9mu dr\u00e1pu na noze jin\u00fdch dinosaur\u016f dromaeosaurid\u016f.<\/p>\n\n

Dal\u0161\u00ed vykop\u00e1vky na m\u00edst\u011b p\u0159inesly dal\u0161\u00ed kosti, v\u010detn\u011b premaxily (p\u0159edn\u00ed \u010d\u00e1st horn\u00ed \u010delisti) a gastralie (hrudn\u00edho ko\u0161e). Tyto kosti umo\u017enily Kirklandovi a jeho koleg\u016fm identifikovat Utahraptora jako nov\u00fd druh, kter\u00e9mu dali jm\u00e9no Utahraptor ostrommaysi.<\/p>\n\n

Fyzick\u00e9 vlastnosti<\/h2>\n\n

Utahraptor byl nejv\u011bt\u0161\u00edm zn\u00e1m\u00fdm dromaeosauridem a mohl dor\u016fst d\u00e9lky a\u017e 23 stop a v\u00e1\u017eit p\u0159es 600 liber. M\u011bl siln\u00e9 zadn\u00ed nohy a dlouh\u00fd, svalnat\u00fd ocas. Jeho dr\u00e1py byly obzvl\u00e1\u0161t\u011b smrt\u00edc\u00ed, p\u0159i\u010dem\u017e dr\u00e1py na rukou byly v\u00edce specializovan\u00e9 na \u0159ez\u00e1n\u00ed ne\u017e u jin\u00fdch dromaeosaurid\u016f. Zuby v p\u0159edn\u00ed \u010d\u00e1sti doln\u00ed \u010delisti byly \u00fahlov\u00e1ny dop\u0159edu v\u00edce ne\u017e u jin\u00fdch raptor\u016f, co\u017e nazna\u010duje jedine\u010dn\u00fd zp\u016fsob krmen\u00ed.<\/p>\n\n

Ned\u00e1vn\u00e9 objevy odhalily, \u017ee Utahraptor byl pokryt pe\u0159\u00edm, co\u017e mu dod\u00e1valo elegantn\u011bj\u0161\u00ed vzhled ne\u017e \u0161upinat\u00e9 vyobrazen\u00ed dinosaur\u016f, kter\u00e1 byla v minulosti b\u011b\u017en\u00e1.<\/p>\n\n

Stejn\u011b jako jin\u00ed maso\u017erav\u00ed dinosau\u0159i pou\u017e\u00edval Utahraptor zp\u016fsob krmen\u00ed \u201euchop a roztrhni\u201c. Kousal a tahal dozadu a pomoc\u00ed vroubkovan\u00fdch zub\u016f trhal maso. Studie uk\u00e1zaly, \u017ee zuby Utahraptora byly dob\u0159e p\u0159izp\u016fsobeny pro \u0159ez\u00e1n\u00ed a kr\u00e1jen\u00ed, co\u017e nazna\u010duje, \u017ee mohl b\u00fdt specializovan\u00fdm pred\u00e1torem.<\/p>\n\n

Kulturn\u00ed dopad<\/h2>\n\n

Utahraptor se stal popul\u00e1rn\u00edm dinosaurem d\u00edky sv\u00e9 impozantn\u00ed velikosti, jedine\u010dn\u00fdm vlastnostem a spojen\u00ed s popul\u00e1rn\u00ed kulturou. Basketbalov\u00fd t\u00fdm Toronto Raptors z NBA p\u0159ijal dinosaura jako sv\u00e9 logo v 90. letech a byl n\u00e1m\u011btem \u201epaleofantastick\u00e9ho\u201c rom\u00e1nu Raptor Red.<\/p>\n\n

V roce 2018 byl Utahraptor ofici\u00e1ln\u011b ozna\u010den za st\u00e1tn\u00edho dinosaura Utahu po kampani veden\u00e9 mlad\u00fdm chlapcem jm\u00e9nem Kenyon Roberts. Objev dinosaura a jeho n\u00e1sledn\u00e1 sl\u00e1va p\u0159isp\u011bly ke zv\u00fd\u0161en\u00ed pov\u011bdom\u00ed o paleontologii a d\u016fle\u017eitosti ochrany fosiln\u00edch zdroj\u016f.<\/p>\n\n
