The specimen, which lived some 161–168 million years in the Jurassic Period, is thought to have failed to complete its metamorphosis into a frog, before being buried in ash and silt.

Because not all frog species undergo metamorphosis (some instead hatch as juvenile frogs straight from the egg), it has been a matter of debate whether frogs' earliest ancestors were first tadpoles.

Their hemoglobin changes. Even their eye pigment changes,” he said. “That’s why frog metamorphosis is a really good model to study hormones and development. It has such a dramatic effect.” ...

They will see a tadpole develop into a frog, a nymph develop into a dragonfly, and a caterpillar develop into a butterfly. Ask students to explore tactile models and overlays of the life cycle of a ...
