Jurassic Giant: World's Oldest Tadpole Unearthed

Researchers in Argentina have discovered the world's oldest-known tadpole fossil, dating back 161 million years to the Jurassic period. The tadpole, belonging to a large frog species, was found in Patagonia and is remarkably well-preserved, with some soft tissues visible. This discovery provides insights into the development of frogs and suggests that tadpoles have remained largely unchanged over millions of years. The study, led by biologist Mariana Chuliver, highlights the significance of these findings in understanding ancient amphibian life.
