Researchers uncover world's oldest-known tadpole, a 161-million-year-old giant

Scientists have found a fossil of the earliest-known tadpole, which lived around 161 million years ago, during the Jurassic period.

Notobatrachus

Notobatrachus (лат.) – рід вимерлих земноводних з надряду Salientia. Представники роду жили в середньо-юрську епоху (келовейський-батський віки, 168,3-163,5 млн років тому) в Південній Америці (Патагонія, Аргентина), тобто хронологічно ближче до сучасних безхвостих, ніж найдавніші жаби з родів Prosalirus і Vieraella.
