Nejv\u011bt\u0161\u00ed dinosaurus v\u0161ech dob? Seznamte se s Patagotitanem mayorem<\/h2>\n\n

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

V roce 2014 u\u010dinili paleontologov\u00e9 p\u0159evratn\u00fd objev: zkamen\u011bl\u00e9 poz\u016fstatky obrovsk\u00e9ho dinosaura, kter\u00fd m\u016f\u017ee b\u00fdt nejv\u011bt\u0161\u00edm, jak\u00fd kdy kr\u00e1\u010del po Zemi. Dinosaurus byl vykop\u00e1n na ran\u010di v Argentin\u011b a dostal jm\u00e9no Patagotitan mayorum, co\u017e znamen\u00e1 \u201eMayo\u016fv patagonsk\u00fd tit\u00e1n\u201c.<\/p>\n\n

Patagotitan byl b\u00fdlo\u017eravec s mohutn\u00fdm t\u011blem, kter\u00e9 nesly obrovsk\u00e9 kon\u010detiny a dlouh\u00fd, svalnat\u00fd ocas. Jen jeho krk byl del\u0161\u00ed ne\u017e \u0161koln\u00ed autobus a jeho celkov\u00e1 d\u00e9lka se odhaduje na v\u00edce ne\u017e 120 stop. S hmotnost\u00ed p\u0159es 70 tun byl Patagotitan t\u011b\u017e\u0161\u00ed ne\u017e tucet africk\u00fdch slon\u016f dohromady.<\/p>\n\n

Porovn\u00e1n\u00ed velikosti a debata<\/h2>\n\n

Obrovsk\u00e1 velikost Patagotitana vyvolala srovn\u00e1n\u00ed s dal\u0161\u00edmi ob\u0159\u00edmi dinosaury, jako byl Argentinosaurus a Puertasaurus. P\u0159esto\u017ee Patagotitan nemus\u00ed b\u00fdt absolutn\u011b nejv\u011bt\u0161\u00edm sauropodem, je rozhodn\u011b jedn\u00edm z nejkompletn\u011bj\u0161\u00edch a nejzachovalej\u0161\u00edch exempl\u00e1\u0159\u016f.<\/p>\n\n

Paleontolog Mathew Wedel poznamen\u00e1v\u00e1, \u017ee dostupn\u00e1 m\u011b\u0159en\u00ed nazna\u010duj\u00ed, \u017ee Patagotitan byl srovnateln\u00fd velikost\u00ed s Argentinosautem. Zd\u016fraz\u0148uje v\u0161ak, \u017ee je pot\u0159eba dal\u0161\u00edho v\u00fdzkumu, aby bylo mo\u017en\u00e9 ur\u010dit, kter\u00fd dinosaurus m\u00e1 titul nejv\u011bt\u0161\u00edho sauropoda.<\/p>\n\n

Geografick\u00e9 roz\u0161\u00ed\u0159en\u00ed a velikostn\u00ed limity<\/h2>\n\n

Je zaj\u00edmav\u00e9, \u017ee v\u0161ichni zn\u00e1m\u00ed superob\u0159\u00ed sauropodi, v\u010detn\u011b Patagotitana, Argentinosauta a Puertaura, z\u0159ejm\u011b ob\u00fdvali stejnou obecnou oblast v k\u0159\u00eddov\u00e9 Argentin\u011b. To nazna\u010duje, \u017ee m\u016f\u017ee existovat horn\u00ed hranice velikosti, kter\u00e9 mohli sauropodi dos\u00e1hnout, mo\u017en\u00e1 kv\u016fli environment\u00e1ln\u00edm faktor\u016fm nebo fyziologick\u00fdm omezen\u00edm.<\/p>\n\n

Faktory p\u0159isp\u00edvaj\u00edc\u00ed k ob\u0159\u00ed velikosti<\/h2>\n\n

D\u016fvody extr\u00e9mn\u00ed velikosti t\u011bchto sauropod\u016f se st\u00e1le diskutuj\u00ed. Paleontolo\u017eka Kristi Curry Rogersov\u00e1 nazna\u010duje, \u017ee vyvinuli sv\u00e1 obrovsk\u00e1 t\u011bla, aby vyu\u017eili hojn\u00e9 zdroje a specializovan\u00e9 fyziologick\u00e9 adaptace, kter\u00e9 jim umo\u017enily prosperovat jako ob\u0159i.<\/p>\n\n

Wedel dod\u00e1v\u00e1, \u017ee v\u011bt\u0161\u00ed velikost poskytovala sauropod\u016fm n\u011bkolik v\u00fdhod, v\u010detn\u011b zv\u00fd\u0161en\u00e9 produkce vajec, ochrany p\u0159ed pred\u00e1tory a schopnosti p\u0159e\u017e\u00edt na potrav\u011b ni\u017e\u0161\u00ed kvality a migrovat na velk\u00e9 vzd\u00e1lenosti.<\/p>\n\n

Pr\u016fb\u011b\u017en\u00fd r\u016fst a budouc\u00ed objevy<\/h2>\n\n

Pozoruhodn\u00e9 je, \u017ee i nejv\u011bt\u0161\u00ed exempl\u00e1\u0159e Patagotitana vykazuj\u00ed v dob\u011b smrti zn\u00e1mky pokra\u010duj\u00edc\u00edho r\u016fstu. To nazna\u010duje, \u017ee i kdy\u017e Patagotitan nen\u00ed nejv\u011bt\u0161\u00edm dinosaurem, jak\u00fd byl kdy objeven, pravd\u011bpodobn\u011b nen\u00ed nejv\u011bt\u0161\u00edm z\u00e1stupcem sv\u00e9ho druhu.<\/p>\n\n

Curry Rogersov\u00e1 v\u011b\u0159\u00ed, \u017ee mohou existovat je\u0161t\u011b v\u011bt\u0161\u00ed dinosau\u0159i, kte\u0159\u00ed je\u0161t\u011b nebyli objeveni. Poukazuje na to, \u017ee v\u0161ichni zn\u00e1m\u00ed superob\u0159\u00ed sauropodi uhynuli d\u0159\u00edve, ne\u017e dos\u00e1hli pln\u00e9 dosp\u011blosti, co\u017e nazna\u010duje, \u017ee mohou existovat je\u0161t\u011b v\u011bt\u0161\u00ed exempl\u00e1\u0159e.<\/p>\n\n

V\u00fdznam a d\u016fle\u017eitost<\/h2>\n\n

Objev Patagotitana mayora je sv\u011bdectv\u00edm o neuv\u011b\u0159iteln\u00e9 rozmanitosti a rozsahu prehistorick\u00e9ho \u017eivota. Zd\u016fraz\u0148uje neust\u00e1l\u00e9 hled\u00e1n\u00ed znalost\u00ed o starov\u011bk\u00e9m sv\u011bt\u011b a fascinaci, kterou dinosau\u0159i pro n\u00e1s dodnes maj\u00ed.<\/p>\n\n

Jak paleontologov\u00e9 budou i nad\u00e1le odkr\u00fdvat nov\u00e9 fos\u00edlie a up\u0159es\u0148ovat sv\u00e9 ch\u00e1p\u00e1n\u00ed t\u011bchto obrovsk\u00fdch tvor\u016f, m\u016f\u017eeme o\u010dek\u00e1vat, \u017ee z\u00edsk\u00e1me je\u0161t\u011b hlub\u0161\u00ed poznatky o pozoruhodn\u00fdch adaptac\u00edch a evolu\u010dn\u00ed historii nejv\u011bt\u0161\u00edch zv\u00ed\u0159at, kter\u00e1 kdy \u017eila.<\/p>","protected":false},"excerpt":{"rendered":"
