But exactly how and when they evolved to begin as tadpoles remains unclear.<\/p>\n<p class=\"dcr-1eu361v\">This new discovery adds some clarity to that timeline. At about 6in (16cm ) long, the tadpole is a younger version of an extinct giant frog.<\/p>\n<p class=\"dcr-1eu361v\">\u201cIt\u2019s starting to help narrow the timeframe in which a frog becomes a frog,\u201d said Ben Kligman, a paleontologist at the Smithsonian National Museum of Natural History who was not involved with the research.<\/p>\n<p class=\"dcr-1eu361v\">The results were published on Wednesday in the journal Nature.<\/p>\n<p class=\"dcr-1eu361v\">The fossil is strikingly similar to the tadpoles of today \u2013 even containing remnants of a gill scaffold system that modern-day tadpoles use to sift food particles from water.<\/p>\n<p class=\"dcr-1eu361v\">That means the amphibians\u2019 survival strategy has stayed tried and true for millions of years, helping them outlast several mass extinctions, Kligman said.<\/p>\n<\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/www.theguardian.com\/science\/2024\/oct\/30\/oldest-ever-giant-tadpole-fossil\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scientists have discovered the oldest-known fossil of a giant tadpole that wriggled around over 160m years ago.
