Zkamen\u011bl\u00e9 poz\u016fstatky Carnufexe byly nalezeny v okrese Chatham County v Severn\u00ed Karol\u00edn\u011b v geologick\u00e9 oblasti zvan\u00e9 Pekinsk\u00fd souvrstv\u00ed. Od za\u010d\u00e1tku paleontologov\u00e9 v\u011bd\u011bli, \u017ee maj\u00ed v rukou n\u011bco v\u00fdjime\u010dn\u00e9ho. Lebka Carnufexe byla bohat\u011b zdobena hrbolky a r\u00fdhami, na rozd\u00edl od v\u0161eho, co kdy vid\u011bli.<\/p>\n\n
Carnufex byl jedine\u010dnou sm\u011bsic\u00ed krokodylomorfn\u00edch a rauisuchidn\u00edch znak\u016f s n\u011bkolika pred\u00e1torsk\u00fdmi dinosau\u0159\u00edmi vlastnostmi nav\u00edc. Jeho velk\u00e1 velikost a dlouh\u00e9 zadn\u00ed nohy ho odli\u0161ovaly od jeho modern\u00edch krokod\u00fdlovit\u00fdch p\u0159\u00edbuzn\u00fdch.<\/p>\n\n
Carnufex byl sou\u010d\u00e1st\u00ed \u201ep\u0159ehl\u00eddky pred\u00e1tor\u016f\u201c, kte\u0159\u00ed soupe\u0159ili o nadvl\u00e1du v prav\u011bk\u00e9 Severn\u00ed Karol\u00edn\u011b. Toto obdob\u00ed bylo sv\u011bdkem vzniku p\u0159edk\u016f krokod\u00fdl\u016f a pt\u00e1k\u016f a Carnufex hr\u00e1l v\u00fdznamnou roli v ekosyst\u00e9mu pred\u00e1tor\u016f.<\/p>\n\n
Objev Carnufexe poskytuje nov\u00e9 poznatky o evoluci krokodylomorf\u016f. Posouv\u00e1 datum jejich v\u00fdskytu ve fosiln\u00edm z\u00e1znamu a zpochyb\u0148uje p\u0159edstavu, \u017ee z\u016fstali od dob dinosaur\u016f v\u00edcem\u00e9n\u011b nezm\u011bn\u011bni.<\/p>\n\n
Na konci triasu byli Carnufex a mnoho dal\u0161\u00edch pred\u00e1tor\u016f vyhubeni v jednom z p\u011bti nejv\u011bt\u0161\u00edch masov\u00fdch vym\u00edr\u00e1n\u00ed v\u0161ech dob. Tato ud\u00e1lost vym\u00edr\u00e1n\u00ed vydl\u00e1\u017edila cestu pro vzestup dinosaur\u016f, kte\u0159\u00ed m\u011bli ovl\u00e1dnout Zemi po dal\u0161\u00edch 135 milion\u016f let.<\/p>\n\n
