V rozlehl\u00e9 a d\u00e1vn\u00e9 krajin\u011b Nov\u00e9ho Mexika se kdysi toulal impozantn\u00ed pred\u00e1tor, jeho\u017e jm\u00e9no odr\u00e1\u017e\u00ed s\u00edlu a hr\u016fzu, kterou vyvol\u00e1val: Dynamoterror dynastes, \u201emocn\u00fd vl\u00e1dce d\u011bsu\u201c. Tento nov\u011b objeven\u00fd tyrannosaur, bl\u00edzk\u00fd p\u0159\u00edbuzn\u00fd ikonick\u00e9ho Tyrannosaura rexe, vrh\u00e1 nov\u00e9 sv\u011btlo na rozmanit\u00fd a dynamick\u00fd sv\u011bt t\u011bchto d\u011bsiv\u00fdch maso\u017eravc\u016f.<\/p>\n\n
Dynamoterror byl kolos\u00e1ln\u00ed bestie, dlouh\u00e1 p\u0159ibli\u017en\u011b 30 stop. Jeho masivn\u00ed t\u011blo zast\u00ednilo ran\u00e9 tyranosaury, ale nedos\u00e1hlo hv\u011bzdn\u00e9ho statusu T. rexe. P\u0159esto\u017ee byl Dynamoterror o n\u011bco men\u0161\u00ed, byl nepochybn\u011b vrcholov\u00fdm pred\u00e1torem ve sv\u00e9m d\u00e1vn\u00e9m kr\u00e1lovstv\u00ed.<\/p>\n\n
Pozdn\u011b k\u0159\u00eddov\u00e9 obdob\u00ed, kdy Dynamoterror ob\u00fdval Zemi, bylo dobou rychl\u00fdch a dramatick\u00fdch evolu\u010dn\u00edch zm\u011bn pro dinosaury. Severn\u00ed Amerika byla rozd\u011blena na dv\u011b \u010d\u00e1sti Z\u00e1padn\u00edm vnitrozemsk\u00fdm mo\u0159em, \u010d\u00edm\u017e vznikly dva odli\u0161n\u00e9 subkontinenty: Laramidie na z\u00e1pad\u011b a Appala\u010die na v\u00fdchod\u011b.<\/p>\n\n
V ji\u017en\u00edch oblastech Laramidie, kde Dynamoterror \u017eil, \u017eila rozmanit\u00e1 \u0161k\u00e1la dinosaur\u016f. K zob\u00e1kovit\u00fdm hadrosaur\u016fm, t\u011b\u017ece obrn\u011bn\u00fdm ankylosaur\u016fm a rohat\u00fdm ceratops\u016fm pat\u0159ilo jen n\u011bkolik soused\u016f, se kter\u00fdmi Dynamoterror sd\u00edlel sv\u00e9 prost\u0159ed\u00ed.<\/p>\n\n
Poz\u016fstatky Dynamoterrora byly objeveny v menefeisk\u00e9 formaci v Nov\u00e9m Mexiku v roce 2012 t\u00fdmem paleontolog\u016f veden\u00fdm Andrewem McDonaldem ze Western Science Center a Douglasem Wolfem ze Zuni Dinosaur Institute for Geosciences. Prvotn\u00ed n\u00e1lez sest\u00e1val z rozdroben\u00fdch kost\u00ed vy\u010dn\u00edvaj\u00edc\u00edch z p\u00edskovce, co\u017e nazna\u010dovalo n\u011bco mimo\u0159\u00e1dn\u00e9ho.<\/p>\n\n
V pr\u016fb\u011bhu let v\u011bdci pe\u010dliv\u011b sestavovali rozpt\u00fdlen\u00e9 \u00falomky kost\u00ed, v\u010detn\u011b dvou prozrazuj\u00edc\u00edch lebe\u010dn\u00edch kost\u00ed naz\u00fdvan\u00fdch \u010deln\u00ed kosti. Tyto kritick\u00e9 \u010d\u00e1sti nakonec odhalily skute\u010dnou identitu fos\u00edlie: d\u0159\u00edve nezn\u00e1m\u00fd druh tyranosaura. Objev byl publikov\u00e1n ve v\u011bdeck\u00e9m \u010dasopise PeerJ.<\/p>\n\n
Dynamoterror pat\u0159\u00ed do specifick\u00e9 podskupiny tyranosaur\u016f, kter\u00e1 zahrnuje n\u011bkter\u00e9 z posledn\u00edch a nejv\u011bt\u0161\u00edch \u010dlen\u016f \u010deledi, jako je T. rex. Jeho existence nazna\u010duje, \u017ee tito odvozen\u00ed tyranosau\u0159i se objevili d\u0159\u00edve, ne\u017e se d\u0159\u00edve p\u0159edpokl\u00e1dalo.<\/p>\n\n
P\u0159\u00edtomnost Dynamoterrora v ji\u017en\u00ed Laramidii poskytuje dal\u0161\u00ed d\u016fkaz toho, \u017ee dinosau\u0159\u00ed komunity na severu a jihu Z\u00e1padn\u00edho vnitrozemsk\u00e9ho mo\u0159e byly odli\u0161n\u00e9. Tento objev podporuje teorii, \u017ee dinosau\u0159i pro\u0161li rychlou diverzifikac\u00ed b\u011bhem obdob\u00ed pozdn\u00ed k\u0159\u00eddy.<\/p>\n\n
Fosiln\u00ed z\u00e1znam dinosaur\u016f z 80 milion\u016f let star\u00fdch hornin ji\u017en\u00ed Laramidie je relativn\u011b \u0159\u00eddk\u00fd, co\u017e d\u011bl\u00e1 objev Dynamoterrora obzvl\u00e1\u0161t\u011b cenn\u00fdm. Nazna\u010duje to existenci mnoha dal\u0161\u00edch nezn\u00e1m\u00fdch dinosaur\u016f, kte\u0159\u00ed kdysi ob\u00fdvali tyto prav\u011bk\u00e9 krajiny.<\/p>\n\n
Objev Dynamoterrora znovu rozdm\u00fdchal p\u00e1tr\u00e1n\u00ed po dal\u0161\u00edch tyranosaurech a jin\u00fdch dinosaurech v severn\u00edch oblastech Laramidie. Paleontologov\u00e9 spekuluj\u00ed, \u017ee by tam mohlo b\u00fdt je\u0161t\u011b mnoho dal\u0161\u00edch neobvykl\u00fdch tyran\u00edch je\u0161t\u011br\u016f, kter\u00e9 \u010dekaj\u00ed na vykop\u00e1n\u00ed a vrhnou dal\u0161\u00ed sv\u011btlo na vzestup a dominanci t\u011bchto impozantn\u00edch pred\u00e1tor\u016f.<\/p>","protected":false},"excerpt":{"rendered":"
