Much of the tadpole’s extraordinary size comes from its long and deep tail. Prior to metamorphosing into an adult, its snout-vent length (i.e. its body length) is comparable to the mature adult.

A new paper in the journal Nature details the oldest known tadpole fossil. Ringing in 20 million years earlier than scientists previously had evidence of, this fossil might get us closer to an answer.

The oldest tadpole fossil ever has been found—and it’s a big one. The discovery in Patagonia shows that frogs have had a tadpole stage for at least 160 million years.
