Bolivijos \u201eToro Toro\u201c nacionaliniame parke aptikti p\u0117dsakai atveria stulbinant\u012f vaizd\u0105 i\u0161 pasaulio, koks jis buvo prie\u0161 ma\u017edaug septyniasde\u0161imt milijon\u0173 met\u0173. Piet\u0173 Amerika ir taip laikoma dinozaur\u0173 fosilij\u0173 lobynu, ta\u010diau \u0161i vieta i\u0161siskiria net tame \u012fsp\u016bdingame kontekste. \u010cia akmenyje tarsi susting\u0119s jud\u0117jimas pasakoja istorij\u0105 be \u017eod\u017ei\u0173, bet su ne\u012ftik\u0117tinu tikslumu.<\/p>\n

Svarbiausias atradimas yra mil\u017eini\u0161ka p\u0117dsak\u0173 sankaupa \u201eCarreras Pampa\u201c teritorijoje, kur rasta apie a\u0161tuoniolika t\u016bkstan\u010di\u0173 \u012fspaud\u0173. Tai did\u017eiausias \u017einomas dinozaur\u0173 p\u0117dsak\u0173 kompleksas pasaulyje, kuriame matyti ne tik sausumoje vaik\u0161\u010diojusi\u0173, bet ir vandenyje jud\u0117jusi\u0173 gyv\u016bn\u0173 \u017eenklai. Tokia gausa leid\u017eia suprasti, kad \u010dia kadaise vir\u0117 intensyvus gyvenimas.<\/p>\n

\u0160ie p\u0117dsakai svarb\u016bs ne vien d\u0117l kiekio, bet ir d\u0117l to, k\u0105 jie leid\u017eia i\u0161skaityti apie senov\u0117s elgsen\u0105. Vietoje atsiveria ne atsitiktinis \u012fspaud\u0173 laukas, o tarsi kryptingas mar\u0161rutas, kur\u012f gyv\u016bnai naudojo nuolat. D\u0117l to mokslininkai \u0161i\u0105 viet\u0105 prilygina prie\u0161istorinei autostradai, kurioje dinozaurai jud\u0117jo pakrant\u0117s linija.<\/p>\n

Vieta kur sustoj\u0119s laikas<\/p>\n

\u201eCarreras Pampa\u201c pavir\u0161ius atrodo kaip paprastas akmens plotas, ta\u010diau i\u0161 ties\u0173 tai sustingusi pakrant\u0117s scena i\u0161 v\u0117lyvojo kreidos laikotarpio. Dauguma \u012fspaud\u0173 priklauso teropodams, tai pl\u0117\u0161riesiems dinozaurams, kuri\u0173 tolimi palikuonys \u0161iandien yra pauk\u0161\u010diai. P\u0117dsakai da\u017eniausiai krypsta dviem ai\u0161kiomis kryptimis, tarsi gyv\u016bnai vaik\u0161\u010diojo palei senovin\u012f e\u017eero krant\u0105.<\/p>\n

Tyrimai rodo, kad \u0161ioje vietoje ilgus milijonus met\u0173 tyvuliavo seklus g\u0117lavandenis e\u017eeras. Mink\u0161tas nuos\u0117d\u0173 sluoksnis, turtingas kalcio karbonat\u0173, idealiai fiksavo kiekvien\u0105 \u017eingsn\u012f ir kartu buvo pakankamai tvirtas, kad \u012fspaudai nei\u0161tirpt\u0173 \u012f purv\u0105. V\u0117liau nuos\u0117dos u\u017eklojo pavir\u0161i\u0173 ir pama\u017eu pavert\u0117 j\u012f akmenine atminties plok\u0161te.<\/p>\n

P\u0117dsak\u0173 \u012fvairov\u0117 ir gyvenimo pulsas<\/p>\n

Labai \u012fdomu, kad p\u0117dsakai i\u0161liko \u012fvairiausi\u0173 dyd\u017ei\u0173, nuo ma\u017e\u0173 jaunikli\u0173 \u017eingsni\u0173 iki dideli\u0173, \u017emogaus \u016bgiui prilygstan\u010di\u0173 dinozaur\u0173 p\u0117d\u0173 \u017eymi\u0173. Tai rodo, kad pakrant\u0117je lank\u0117si skirtingo am\u017eiaus gyv\u016bnai ir tikriausiai i\u0161tisos grup\u0117s. Mokslininkai atskyr\u0117 vienuolika p\u0117dsak\u0173 tip\u0173, susijusi\u0173 su \u0117jimu, ir dar kelis, rodan\u010dius jud\u0117jim\u0105 vandenyje.<\/p>\n

Tokie duomenys leid\u017eia \u012ftarti, jog vieta buvo ne trumpalaik\u0117 stotel\u0117, o nuolat naudojama erdv\u0117. Jauni ir suaug\u0119 individai \u010dia jud\u0117jo tuo pa\u010diu mar\u0161rutu, galb\u016bt ie\u0161kodami maisto ar seklumose saugesni\u0173 per\u0117jim\u0173. Skirtingi p\u0117dsak\u0173 tipai liudija, kad krant\u0105 naudojo ne viena r\u016b\u0161is, o visas vietinis gyv\u016bn\u0173 pasaulis.<\/p>\n

Jud\u0117jimas kuris primena autostrad\u0105<\/p>\n

\"\"\/<\/p>\n

\u201eCarreras Pampa\u201c unikalum\u0105 sustiprina tai, kad \u010dia rasta ir p\u0117dsak\u0173, kurie paprastai nei\u0161lieka. Tarp \u012fspaud\u0173 matomos uodeg\u0173 paliktos vagos, atsiradusios gyv\u016bnams slystant ar bandant i\u0161laikyti pusiausvyr\u0105 dumble. Taip pat pasteb\u0117ti ploni br\u0117\u017eiai, b\u016bdingi plaukiantiems dinozaurams, kai kojos tik lengvai paliesdavo dugn\u0105.<\/p>\n

Dar vienas i\u0161skirtinis bruo\u017eas yra tai, kad daug p\u0117dsak\u0173 rodo b\u0117gim\u0105, o ne l\u0117t\u0105 vaik\u0161\u010diojim\u0105. \u017dingsnio ilgiai da\u017enai atitinka greit\u0105 jud\u0117jim\u0105, galb\u016bt med\u017eiokl\u0119, pab\u0117gim\u0105 ar skub\u0173 keliavim\u0105 tarp maitinimosi viet\u0173. Tod\u0117l \u0161i pakrant\u0117 gal\u0117jo b\u016bti svarbi nat\u016brali trasa, kuria dinozaurai jud\u0117jo taip reguliariai, kad j\u0173 kelias tapo tikra prie\u0161istorine magistrale.<\/p>\n","protected":false},"excerpt":{"rendered":"Bolivijos \u201eToro Toro\u201c nacionaliniame parke aptikti p\u0117dsakai atveria stulbinant\u012f vaizd\u0105 i\u0161 pasaulio, koks jis buvo prie\u0161 ma\u017edaug septyniasde\u0161imt…\n","protected":false},"author":2,"featured_media":61653,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[15],"tags":[25,14464,14470,30,31,14463,14469,1660,34,35,24,32,33,37,39,36,38,40,421,23,22,44,28,29,14465,14468,14466,14467,26,27,74,75,76],"class_list":{"0":"post-61652","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-pasaulis","8":"tag-antrastes","9":"tag-argentinoje","10":"tag-autostrada","11":"tag-breaking-news","12":"tag-breakingnews","13":"tag-busenoje","14":"tag-dinozauru","15":"tag-dydzio","16":"tag-featured-news","17":"tag-featurednews","18":"tag-headlines","19":"tag-latest-news","20":"tag-latestnews","21":"tag-lietuva","22":"tag-lietuviu","23":"tag-lithuania","24":"tag-lithuanian","25":"tag-lt","26":"tag-mokslininkai","27":"tag-naujienos","28":"tag-news","29":"tag-pasaulis","30":"tag-populiariausios-naujienos","31":"tag-populiariausiosnaujienos","32":"tag-rasta","33":"tag-soko","34":"tag-sunkiai","35":"tag-suvokiamo","36":"tag-top-stories","37":"tag-topstories","38":"tag-world","39":"tag-world-news","40":"tag-worldnews"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@lt\/115718255180575082","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/posts\/61652","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/comments?post=61652"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/posts\/61652\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/media\/61653"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/media?parent=61652"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/categories?post=61652"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/tags?post=61652"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
