Fos\u00edlie z d\u00e1vno minul\u00e9 \u00e9ry<\/h2>\n\n

St\u0159edn\u00ed jura, trvaj\u00edc\u00ed p\u0159ibli\u017en\u011b od 174 do 163 milion\u016f let p\u0159. n. l., byla z\u00e1sadn\u00edm obdob\u00edm v historii dinosaur\u016f. V t\u00e9to \u00e9\u0159e vzl\u00e9tli prvn\u00ed pt\u00e1ci, tyranosau\u0159i zapo\u010dali svou evolu\u010dn\u00ed cestu a objevili se obrov\u0161t\u00ed sauropodi. Fos\u00edlie z tohoto obdob\u00ed jsou v\u0161ak vz\u00e1cn\u00e9, co\u017e d\u011bl\u00e1 objev na ostrov\u011b Skye obzvl\u00e1\u0161t\u011b cenn\u00fdm.<\/p>\n\n

Stopy tit\u00e1n\u016f a pred\u00e1tor\u016f<\/h2>\n\n

Stopy objeven\u00e9 pobl\u00ed\u017e Brothers’ Point odhaluj\u00ed rozmanitost dinosaur\u016f, kte\u0159\u00ed kdysi ob\u00fdvali ostrov. Velk\u00e9, kruhov\u00e9 otisky, n\u011bkter\u00e9 velk\u00e9 jako pneumatiky aut, nazna\u010duj\u00ed p\u0159\u00edtomnost vysok\u00fdch sauropod\u016f. Tito dlouhokrc\u00ed, bachrat\u00ed b\u00fdlo\u017eravci pat\u0159ili k nejv\u011bt\u0161\u00edm suchozemsk\u00fdm \u017eivo\u010dich\u016fm, kte\u0159\u00ed kdy kr\u00e1\u010deli po Zemi.<\/p>\n\n

Krom\u011b stop sauropod\u016f identifikovali v\u011bdci tak\u00e9 otisky vytvo\u0159en\u00e9 t\u0159\u00edprst\u00fdmi dinosaury, kte\u0159\u00ed chodili po zadn\u00edch noh\u00e1ch. P\u0159edpokl\u00e1d\u00e1 se, \u017ee tyto otisky zanechali teropodi, skupina dvounoh\u00fdch dinosaur\u016f, mezi n\u011b\u017e pat\u0159\u00ed i ob\u00e1van\u00fd Tyrannosaurus rex. Teropodi na Skye mohli b\u00fdt ran\u00fdmi p\u0159\u00edbuzn\u00fdmi tohoto ikonick\u00e9ho pred\u00e1tora.<\/p>\n\n

Dynami\u010dt\u00ed sauropodi: sou\u0161 i voda<\/h2>\n\n

Stopy poskytuj\u00ed p\u0159esv\u011bd\u010div\u00fd d\u016fkaz toho, \u017ee sauropodi nebyli omezeni na vodn\u00ed prost\u0159ed\u00ed, jak se kdysi v\u011b\u0159ilo. M\u00edsto toho nazna\u010duj\u00ed, \u017ee tito masivn\u00ed plazi byli velmi p\u0159izp\u016fsobiv\u00ed a zkoumali celou \u0159adu stanovi\u0161\u0165. Objev ukazuje, \u017ee sauropodi byli schopni chodit po sou\u0161i a dokonce brodit se v m\u011blk\u00fdch pob\u0159e\u017en\u00edch vod\u00e1ch.<\/p>\n\n

\u201eNebyli omezeni na \u017eivot ve vod\u011b,\u201c vysv\u011btluje Dr. Stephen Brusatte, paleontolog z University of Edinburgh. \u201eByli to dynami\u010dt\u00ed a energi\u010dt\u00ed \u017eivo\u010dichov\u00e9, kte\u0159\u00ed se odv\u00e1\u017eili vstoupit do r\u016fzn\u00fdch prost\u0159ed\u00ed.\u201c<\/p>\n\n

Stopy na ostrov\u011b Skye poskytuj\u00ed vz\u00e1cn\u00fd pohled na evolu\u010dn\u00ed historii dinosaur\u016f. Podporuj\u00ed teorii, \u017ee sauropodi byli velmi \u00fasp\u011b\u0161n\u00ed a p\u0159izp\u016fsobiv\u00ed tvorov\u00e9, kte\u0159\u00ed hr\u00e1li v\u00fdznamnou roli ve sv\u00e9m ekosyst\u00e9mu.<\/p>\n\n

Ostrov Skye se uk\u00e1zal b\u00fdt v\u00fdznamnou lokalitou dinosaur\u016f a v posledn\u00edch letech vydal stovky stop. Jedine\u010dn\u00e9 geologick\u00e9 rysy ostrova a hojn\u00e9 fos\u00edlie poskytly neoceniteln\u00e9 poznatky o rozmanitosti a v\u00fdvoji t\u011bchto d\u00e1vn\u00fdch tvor\u016f.<\/p>\n\n
