Nov\u00fd druh ankylosaura objeven v Chile s jedine\u010dn\u00fdm ocasem<\/h2>\n\n

Objev a v\u00fdznam<\/h2>\n\n

V such\u00e9 oblasti Patagonie v Chile ud\u011blali v\u011bdci \u00fa\u017easn\u00fd objev: t\u00e9m\u011b\u0159 kompletn\u00ed zkamen\u011blou kostru dinosaura s neobvykl\u00fdm kyjovit\u00fdm ocasem. Ocas, na rozd\u00edl od \u010dehokoli, co bylo kdy vid\u011bno u jin\u00e9ho dinosaura, m\u00e1 sedm p\u00e1r\u016f ploch\u00fdch, listovit\u00fdch kost\u011bn\u00fdch \u0161upin spojen\u00fdch dohromady.<\/p>\n\n

Kostra pat\u0159\u00ed k nov\u00e9mu druhu obrn\u011bn\u00e9ho dinosaura pojmenovan\u00e9ho Stegouros elengassen. \u017dil na Zemi p\u0159ibli\u017en\u011b p\u0159ed 72 a\u017e 75 miliony let a m\u016f\u017ee odhalit ran\u00fd evolu\u010dn\u00ed rozkol ve strom\u011b rodu ankylosaur\u016f.<\/p>\n\n

Charakteristika Stegouros elengassen<\/h2>\n\n

Stegouros elengassen byl b\u00fdlo\u017eravec, kter\u00fd chodil po v\u0161ech \u010dty\u0159ech a m\u011b\u0159il na v\u00fd\u0161ku m\u00e9n\u011b ne\u017e dva metry a na d\u00e9lku sedm metr\u016f. M\u011bl m\u00e9n\u011b t\u011blesn\u00e9ho brn\u011bn\u00ed a \u0161t\u00edhlej\u0161\u00ed kon\u010detiny ne\u017e ostatn\u00ed ankylosau\u0159i.<\/p>\n\n

Nejv\u00fdrazn\u011bj\u0161\u00edm rysem dinosaura je jeho ocas, kter\u00fd byl p\u0159irovn\u00e1v\u00e1n k azt\u00e9ck\u00e9 bojov\u00e9 palici zvan\u00e9 macuahuitl. Srostl\u00fd, ostnat\u00fd ocas mohl b\u00fdt pokryt\u00fd \u017eiletkov\u011b ostr\u00fdmi pl\u00e1ty keratinu, co\u017e z n\u011bj d\u011blalo ob\u00e1vanou zbra\u0148.<\/p>\n\n

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

Objev Stegouros elengassen vrh\u00e1 sv\u011btlo na ranou evoluci ankylosaur\u016f. Ran\u00ed ankylosau\u0159i nalezen\u00ed na severn\u00ed polokouli nem\u011bli ocasn\u00ed palice, zat\u00edmco pozd\u011bj\u0161\u00ed exempl\u00e1\u0159e vyvinuly ocasy tvo\u0159en\u00e9 ztuhl\u00fdmi obratli, kter\u00e9 tvo\u0159ily tup\u00fd tvar kladiva.<\/p>\n\n

Jedine\u010dn\u00fd ocas Stegouros elengassen nazna\u010duje, \u017ee m\u016f\u017ee p\u0159edstavovat ranou evolu\u010dn\u00ed v\u011btev obrn\u011bn\u00fdch dinosaur\u016f, kter\u00e1 se odch\u00fdlila od hlavn\u00ed linie ankylosaur\u016f, kdy\u017e se superkontinent Pangea rozpadl. Tento rozkol mohl v\u00e9st k v\u00fdvoji odli\u0161n\u00fdch lini\u00ed ankylosaur\u016f na severn\u00ed a ji\u017en\u00ed polokouli.<\/p>\n\n

V\u011bdci nazna\u010duj\u00ed, \u017ee m\u016f\u017ee existovat cel\u00e1 linie ankylosaur\u016f, kter\u00e1 je\u0161t\u011b nebyla objevena v tom, co b\u00fdvalo Gondwana, ji\u017en\u00ed superkontinent, kter\u00fd existoval v obdob\u00ed jury.<\/p>\n\n
