PRAHA – Pri razbe pra\u017esk\u00e9ho metra D na\u0161iel zberate\u013e skamenel\u00edn Radek Labu\u0165a fosiliu doteraz nezn\u00e1meho druhu \u010dl\u00e1nkono\u017eca z obdobia prvoh\u00f4r. \u017dil pribli\u017ene pred 448 mili\u00f3nmi rokov, teda v obdob\u00ed pred n\u00e1stupom rozsiahleho za\u013eadnenia, ktor\u00e9 viedlo k prv\u00e9mu hromadn\u00e9mu vymieraniu na Zemi. Pod\u013ea Luk\u00e1\u0161a Laibla z Geologick\u00e9ho \u00fastavu Akad\u00e9mie vied (GL\u00da AV \u010cR) ide o unik\u00e1tny n\u00e1lez, ktor\u00fd men\u00ed poh\u013ead na roz\u0161\u00edrenie t\u00fdchto \u017eivo\u010d\u00edchov. N\u00e1lez je o to vz\u00e1cnej\u0161\u00ed, ke\u010f\u017ee to bol \u017eivo\u010d\u00edch bez tvrdej schr\u00e1nky. \n<\/p>\n
Dvojcentimetrov\u00fa fos\u00edliu na\u0161iel Labu\u0165a na halde kame\u0148a vy\u0165a\u017een\u00e9ho pri razbe metra. Na prv\u00fd poh\u013ead pripom\u00ednala kr\u00ed\u017eenca pav\u00faka a trilobita. „Uk\u00e1zalo sa, \u017ee ide o vedu doteraz nezn\u00e1my druh, bl\u00edzko pr\u00edbuzn\u00fd trilobitom. Na rozdiel od nich v\u0161ak mal len m\u00e4kk\u00fd pancier. Pomenovali sme ho Soomaspis labutai, na po\u010des\u0165 jeho objavite\u013ea, „uviedol Laibl.<\/p>\n
Pod\u013ea neho vedci v\u010faka n\u00e1lezu prehodnotili svoj n\u00e1zor na oblas\u0165 v\u00fdskytu tohto druhu \u017eivo\u010d\u00edcha. Rod Soomaspis, do ktor\u00e9ho sa rad\u00ed, doteraz pova\u017eovali za mimoriadne zvl\u00e1\u0161tny druh. „Jeho najbli\u017e\u0161\u00ed pr\u00edbuzn\u00fd Soomaspis splendida bol objaven\u00fd v Ju\u017enej Afrike v 90. rokoch minul\u00e9ho storo\u010dia,“ uviedol. Odborn\u00edci si dlho mysleli, \u017ee i\u0161lo o miestnu raritu.<\/p>\n
Pra\u017esk\u00fd objav to ale vyvr\u00e1til, preto\u017ee z neho vyplynulo, \u017ee rod Soomaspis musel ob\u00fdva\u0165 rozsiahle \u00fazemia vtedaj\u0161ieho kontinentu Gondwana. S\u00fa\u010dasn\u00fa Prahu a Ju\u017en\u00fa Afriku od seba v tom \u010dase toti\u017e delili tis\u00edce kilometrov. „N\u00e1lez Radka Labuti je tak trochu, ako keby ste vo Vltave zni\u010dohoni\u010d objavili ve\u013ekraba japonsk\u00e9ho,“ poznamenal Laibl.<\/p>\n
Soomaspis labutai je mal\u00fd \u010dl\u00e1nkono\u017eec s oc\u00e1skom a pancierom, ktor\u00fd bol pokryt\u00fd drobn\u00fdmi jamkami. K\u00fdm Soomaspis labutai \u017eil e\u0161te pred ordovickou dobou \u013eadovou, jeho pr\u00edbuzn\u00fd z Ju\u017enej Afriky sa objavuje a\u017e po \u0148om. Pod\u013ea vedcov to sved\u010d\u00ed o tom, \u017ee tieto \u017eivo\u010d\u00edchy boli schopn\u00e9 pre\u010dka\u0165 prudk\u00e9 klimatick\u00e9 zmeny, ktor\u00e9 mnoho in\u00fdch nepre\u017eilo. „Ich tajomstvom bolo pravdepodobne to, \u017ee ob\u00fdvali hlb\u0161ie \u010dasti mora, ktor\u00fdch sa klimatick\u00e9 zmeny pr\u00edli\u0161 nedotkli, a zvl\u00e1dli pre\u017ei\u0165 v prostred\u00ed s n\u00edzkym obsahom kysl\u00edka,“ dodal Laibl. Soomaspis labutai bude k videniu v st\u00e1lej expoz\u00edcii N\u00e1rodn\u00e9ho m\u00fazea, kam ho Labu\u0165a venoval.<\/p>\n","protected":false},"excerpt":{"rendered":"PRAHA – Pri razbe pra\u017esk\u00e9ho metra D na\u0161iel zberate\u013e skamenel\u00edn Radek Labu\u0165a fosiliu doteraz nezn\u00e1meho druhu \u010dl\u00e1nkono\u017eca z…\n","protected":false},"author":2,"featured_media":62253,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[24422,10506,33,802,43,40,42,36,50,49,48],"class_list":{"0":"post-62274","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-svet","8":"tag-fosilia","9":"tag-metro","10":"tag-news","11":"tag-praha","12":"tag-sk","13":"tag-slovak","14":"tag-slovencina","15":"tag-spravy","16":"tag-svet","17":"tag-world","18":"tag-world-news"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@sk\/116523781649742759","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts\/62274","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/comments?post=62274"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts\/62274\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/media\/62253"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/media?parent=62274"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/categories?post=62274"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/tags?post=62274"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
