Dinosaurusi oli hiigelsuuri, aga oli ka v\u00e4iksemaid. Ka teadlaste vahelisi v\u00e4itlusi on sauruste asjus olnud suuremaid ja v\u00e4iksemaid.<\/p>\n

\u00dchel suurel ja pikaajalisel v\u00e4itlusel on n\u00fc\u00fcd aga l\u00f5pp. N\u00fc\u00fcd on teada, et \u00fcks muidu \u00fcsna t\u00fcrannosauruse moodi saurus, ainult et omajagu v\u00e4iksem, oli t\u00f5epoolest omaette saurus nimega nanot\u00fcrannus, mitte aga lihtsalt noor ja t\u00e4iskasvamata t\u00fcrannosaurus.<\/p>\n

Lahenduse t\u00f5i Ameerika teadlaste uus uuring.<\/p>\n

Lindsay Zanno ja James Napoli, m\u00f5lemad P\u00f5hja-Carolina Osariigi\u00fclikoolist Raleigh’s, uurisid l\u00e4hemalt \u00fcht tuntud nanot\u00fcrannuse fossiili, aastal 2006 Montana osariigist leitut.<\/p>\n

Fossiil oli t\u00e4helepanuv\u00e4\u00e4rne selle poolest, et on s\u00e4ilitanud l\u00e4bi miljonite aastate hetke, kus nanot\u00fcrannus v\u00f5itleb sarvilise sauruse tritseeratopsiga.<\/p>\n

<\/p>\n

Zanno ja Napoli kirjutavad ajakirjas Nature<\/a>, et see v\u00f5itlev nanot\u00fcrannus oli nende p\u00f5hjaliku anal\u00fc\u00fcsi j\u00e4rgi umbes 20-aastane, seega t\u00e4iesti t\u00e4iskasvanud ja kehaliselt k\u00fcps loom.<\/p>\n

Samas erines ta mitme olulise tunnuse poolest t\u00fcrannosaurustest \u2014 esik\u00e4pad olid tal suuremad, hambaid oli suus rohkem ja sabas oli selgrool\u00fclisid v\u00e4hem kui t\u00fcrannosaurusel.<\/p>\n

Kui nanot\u00fcrannus oleks k\u00f5igest noor, m\u00fcrsikueas t\u00fcrannosaurus, siis kummutaks see senised arusaamad kasv\u00f5i selgrool\u00fclide arengust.<\/p>\n

Nii j\u00e4reldavadki Zanno ja Napoli, et nanot\u00fcrannuse sirgumine t\u00fcrannosauruseks ei ole mitte ainult ebat\u00f5en\u00e4oline, vaid t\u00e4iesti v\u00f5imatu.<\/p>\n

Paljude sauruseuurijate t\u00f6\u00f6 paiskab t\u00f5demus ses m\u00f5ttes pisut segi, et seni on mitmeidki nanot\u00fcrannuse fossiilide p\u00f5hjal tehtud j\u00e4reldusi, sealhulgas nende k\u00e4itumise kohta, suhteliselt kergel meelel laiendatud t\u00fcrannosaurustele. N\u00fc\u00fcd enam nii teha ei saa ja seni tehtu tuleb \u00fcle vaadata.<\/p>\n

Veel v\u00f5ib Zanno ja Napoli avastuse p\u00f5hjal hakata m\u00f5tlema, et kriidiajastu lihas\u00f6\u00f6jate sauruste elurikkus v\u00f5is olla seni arvatust suurem.<\/p>\n

V\u00f5ib isegi olla, et m\u00f5ned muudki fossiilid, mida on varem m\u00f5ne tuntud liigi noorloomade omaks peetud, esindavad tegelikult hoopis omaette liiki.<\/p>\n

Igal juhul on selge, et t\u00fcrannosaurusel, sel suurimal teadaoleval lihas\u00f6\u00f6jal hiidsisalikul, oli s\u00f5braks v\u00f5i konkurendiks v\u00e4iksem, n\u00f5tkem ja vilkam hirmutis, nanot\u00fcrannus.<\/p>\n

Pildil r\u00fcndavad t\u00e4iskasvanud nanot\u00fcrannused noort t\u00fcrannosaurust.<\/p>\n
