Last week I read a piece in Smithsonian Magazine on the oldest fossil tadpole yet described—161 million years old! Jurassic tadpole! That’s so old!!

I love frogs but I don’t actually know a lot about them, so it was really interesting to read this piece and learn that basic frog metamorphosis is really really really old. If you’re interested in reading the original Nature paper this piece is based on, the Smithsonian article has a sharing link to Nature that will allow you to read the full text.

P.S. If you’re looking to have a few interesting science and history stories land in your feed reader every day, I can highly recommend adding Smithsonian Magazine to your reader. Here’s the RSS link: https://www.smithsonianmag.com/rss/latest_articles/
