Jurassic Tadpole Surprise: Ancient Life Frozen in Time

Argentinian scientists have unearthed the oldest-known tadpole fossil from 161 million years ago, offering insights into frog evolution. The tadpole, part of Notobatrachus degiustoi species, is well-preserved, revealing soft tissue details and showing minimal changes in tadpole morphology since the Jurassic Period.

In a groundbreaking discovery, scientists in Argentina have unearthed the oldest-known tadpole fossil from the Jurassic Period, approximately 161 million years ago.

The fossil, which belongs to the species Notobatrachus degiustoi, is exceptionally well-preserved, displaying soft tissue details rarely seen in such finds, including nerves and eyes.

This find, uncovered during a 2020 dinosaur dig in Santa Cruz, Argentina, demonstrates that tadpole morphology has remained largely unchanged for millions of years, providing new insights into frog evolution.
